Best Universal Side Mount Boat Throttle Control for Outboards

#1 · Best Overall

1. KinHall Outboard Remote Control Box

• Weight: 5.3 lb
• Material: Zinc Alloy
• Operation Mode: Electric

Best for: Multi-brand compact control box.

Why it ranks #1: Its listed fit spans Yamaha, Suzuki, Honda, Mercury, and BRP, making it the broadest stated engine match; the zinc-alloy shell and compact footprint add useful specifics.

A listed 5.25-pound weight and 14.1-by-6.1-inch footprint make this KinHall control a compact, portable option for buyers comparing side-mount boxes across engine brands. Its stated compatibility spans Yamaha, Suzuki, Honda, Mercury, and BRP, while a removable drip tray and anti-slip feet add practical installation details.

The broad named engine-brand compatibility can help buyers considering a control for different outboard makes, while the compact footprint and low listed weight support handling and placement in a space-conscious helm. A rust-resistant, plastic-sprayed zinc-alloy shell is specified for saltwater exposure and daily wear. The removable drip tray can be taken off for cleaning, and anti-slip feet provide a stated grip feature. The listing describes forward and reverse operation, but does not supply connector or harness specifications.

Skip it if you need a specified 8-pin Mercury harness; FASWORX 881170A15 lists that connector with a 15-foot lead.

Buyers seeking a compact control with multiple named outboard brands in its compatibility list may consider the KinHall. Its missing connector and harness details make it less suitable when replacing a specific wired control.

#2 · Best Mercury Replacement

2. FASWORX 881170A15 Control Box

• Weight: 10.48 lb

Best for: Mercury Gen I OEM-style swap.

Why it ranks #2: This Gen I side-mount replacement specifies a traditional 8-pin connector, 15-foot harness, trim switch, and compatibility with Mercury, Mariner, and 1993+ Force using Mercury-style cables.

The traditional 8-pin connector and 15-foot harness make this FASWORX control a specific match for many Mercury side-mount installations. It is cross-referenced to Mercury and Quicksilver 881170A15, 8M0178521, 881170A1, and 16900A15 Gen I controls, with a handle-mounted trim switch for equipped outboards.

FASWORX identifies this as a replacement for Mercury and Quicksilver side-mount controls and states compatibility with current Mercury/Mariner outboards and 1993+ Force engines using Mercury-style cables. That gives buyers a defined replacement path instead of a universal fit claim. The 8-pin, 15-foot harness corresponds to the stated Mercury installation format, and the handle-mounted trim switch supports trim operation from the control. Front-mount trim wiring is also supported, making wiring layout a relevant installation consideration.

Skip it if you need a four-stroke 14-pin control; POWEROB TEC 881170A13 lists that configuration with a five-meter harness and power trim.

Choose this FASWORX unit for a Mercury/Mariner or specified Force replacement when its Gen I 8-pin layout and 15-foot lead match the boat. Cable style and connector configuration remain essential fit checks.

#3 · Best 2-Stroke Fit

3. POWEROB TEC Gen I Side Mount

• Material: Aluminum
• Operation Mode: Mechanical

Best for: Mercury two-stroke keyed control.

Why it ranks #3: The listing identifies a Mercury 2-stroke Gen I control with 8-pin and 12-pin references, a 5-meter harness, power trim switch, and switch key.

A key switch accompanies the power-trim control on this POWEROB TEC side-mount unit, bringing ignition-related and trim functions together in its listed Mercury 881170A15-style setup. It specifies a five-meter harness and 8-pin configuration for two-stroke applications, with aluminum construction for the control box.

The five-meter harness gives installers a stated cable length, and the 8-pin configuration narrows the intended wiring setup. A power trim switch supports trim adjustment at the control, while the included key switch adds a listed helm function. POWEROB TEC identifies the unit for Mercury two-stroke use and references Mercury inflatable-boat components. It also mentions 12-pin alongside 8-pin in its feature text, so buyers should treat connector format as a critical match rather than assume one plug fits all applications.

Skip it if you need a clearly specified four-stroke 14-pin control; POWEROB TEC 881170A13 identifies that engine and connector configuration.

Mercury two-stroke owners seeking a side-mount control with trim, key switch, and a five-meter lead may find this feature set useful. Confirm the exact connector configuration, since the listing mentions both 8-pin and 12-pin.

#4 · Longest Listed Harness

4. VEVOR 881170A15 Control

• Weight: 9.8 lb

Best for: Mercury two-stroke replacement.

Why it ranks #4: Designed for Mercury PT 2-stroke engines, it includes a 16.3-foot harness and describes a die-cast aluminum housing with an ABS handle.

The 16.3-foot harness pairs this VEVOR side-mount control with Mercury PT two-stroke outboards, giving installations with a longer lead a specified cable length to work with. Its die-cast aluminum housing and aluminum-alloy interior provide a metal-bodied control, while the ABS handle is described as crack-resistant for frequent operation.

Neutral is engaged by pressing the neutral control before switching between forward and reverse, a defined operating sequence for routine gear changes. The 16.3-foot harness gives the installation a specified lead length, while the die-cast aluminum housing and aluminum-alloy interior provide a robust enclosure. Compatibility is specifically stated for Mercury PT two-stroke outboard engines, so this is a focused replacement choice rather than a broadly specified universal control. The supplied details do not identify a trim switch or key.

Skip it if you have a Mercury four-stroke or need a stated trim switch; the POWEROB TEC 881170A13 specifies four-stroke, 14-pin use and power trim.

Mercury PT two-stroke owners seeking a side-mount control with a 16.3-foot harness should consider this VEVOR. Its stated engine compatibility is narrow, so match the control to the outboard before choosing it.

#5

5. Generic 881170A15 Control Box

• Material: Aluminum
• Operation Mode: Mechanical

Best for: Mechanical trim control replacement.

Why it ranks #5: This side-mount Mercury 2-stroke listing specifies an 8-pin, 15-foot harness, pull-to-open design, and integrated power trim switch, but only a 90-day warranty.

A five-meter wiring harness gives this 881170A15 side-mount control a defined lead length for installation, while its integrated power trim switch enables angle adjustment from the control. The aluminum box uses a pull-to-open handle and is listed for Mercury two-stroke remote-control applications.

The included five-meter harness and 8-pin specification identify the wiring format and reach, useful when planning a replacement installation. Its power trim switch supports adjustment of the outboard angle from the control, while the pull-to-open mechanism specifies how the handle operates. The listing names Mercury two-stroke use and particular Mercury inflatable-boat components, making this a more targeted choice than the broad side-mount label alone suggests. Its operation mode is mechanical, and the housing material is aluminum.

Skip it if you need a control explicitly listed for Mercury four-stroke 14-pin engines; BOATCON 881170A13 specifies that configuration.

Mercury two-stroke owners needing a side-mount mechanical control with trim and a five-meter lead may find this configuration relevant. Check that its 8-pin format and stated application match the boat's existing setup.

#6 · Best 14-Pin Option

6. POWEROB TEC 881170A13 Control

• Weight: 5 kg
• Material: Aluminum
• Operation Mode: Manual

Best for: Mercury four-stroke 14-pin fit.

Why it ranks #6: It targets Mercury 4-stroke installations with a 14-pin side-mount control, 5-meter harness, power trim switch, key switch, and pull-to-open operation.

The 14-pin specification makes this POWEROB TEC 881170A13 a targeted side-mount option for Mercury four-stroke outboards using that connection. Its feature listing also includes power trim, a key switch, and a pull-to-open handle, bringing several named control functions into one aluminum assembly.

The 14-pin four-stroke designation helps narrow the fit to the stated Mercury control configuration, while the power trim switch supports angle adjustment from the helm. A key switch adds another listed function, and the pull-to-open handle identifies the operating style. POWEROB TEC specifies an aluminum control box and a five-meter harness in the title, giving installers a material and lead-length reference. The listing does not provide a detailed engine-model compatibility table in the supplied facts.

Skip it if you need a 16.5-foot harness and flameout rope; BOATCON 881170A13 lists both with its 14-pin four-stroke control.

Mercury four-stroke owners whose setup uses 14 pins can consider this POWEROB TEC control for its trim, key switch, and five-meter harness. Specific engine-model fit is not detailed in the supplied information.

#7

7. BOATCON 881170A13 Control

• Material: Aluminum
• Operation Mode: Manual

Best for: Right-hand Mercury 14-pin replacement.

Why it ranks #7: This Mercury aftermarket replacement specifies a 14-pin 4-stroke fit, 16.5-foot harness, trim switch, key, flameout rope, and installation accessory package.

A right-hand, pull-to-open handle and 16.5-foot harness define this BOATCON 881170A13 replacement for Mercury four-stroke, 14-pin outboards. The listed package adds a trim switch, key, and flameout rope, combining several helm functions while clearly identifying the control as an aftermarket replacement rather than an original OEM part.

The 14-pin connection and stated four-stroke application help buyers identify the intended Mercury configuration, while the 16.5-foot harness gives a specific lead length for installation planning. The trim switch supports angle adjustment, and the included key and flameout rope add the other listed helm components. BOATCON describes a right-hand pull-to-open control and says the handle rotates to adjust neutral, gear, and throttle. An installation accessory package is included, but the unit is explicitly aftermarket.

Skip it if you require an original OEM control box; this BOATCON unit is explicitly listed as an aftermarket replacement.

Mercury four-stroke owners needing a right-hand 14-pin replacement with a long harness and included helm components may consider BOATCON. Its aftermarket status and connector configuration are important boundaries for replacement fit.

#8

8. SeaStar Xtreme CHX8051P

• Weight: 16 oz
• Material: Chrome
• Operation Mode: Off

Best for: Chrome control with cutoff switch.

Why it ranks #8: The side-mount chrome control includes both a trim switch and engine cut-off switch, but the listing does not state a multi-brand engine fit or harness length.

An integrated engine cut-off switch sets this chrome SeaStar Xtreme side-mount control apart, adding a shutoff function alongside its trim switch. The package lists both switches with the control, giving boaters seeking helm-mounted engine and trim functions a clearly specified combination in a marine-compatible unit.

The included trim switch provides a control for engine trim at the helm, while the engine cut-off switch adds a separate shutdown function in the same side-mount assembly. Chrome is the listed material and finish, and stainless steel is specified for the contact material. SeaStar identifies marine vehicles as compatible, but the supplied facts do not name a particular outboard brand, cable type, or harness length, so those details should guide replacement decisions rather than assuming a specific connection.

Skip it if you need a stated Mercury connector and harness; FASWORX 881170A15 specifies an 8-pin plug and 15-foot lead.

This SeaStar suits marine buyers who want a chrome side-mount control with both trim and engine cut-off switches. Because connector and engine details are not supplied, it is best where those fit requirements are already established.

#9

9. SeaStar Xtreme CHX8554P

• Material: Polypropylene
• Operation Mode: automatic

Best for: Black SeaStar trim control.

Why it ranks #9: This black side-mount SeaStar control includes a trim switch and lists boat compatibility, but provides no pin count, harness length, or specific engine range.

The included trim switch gives this black SeaStar Xtreme side-mount control a helm-based trim function in a polypropylene-bodied assembly. SeaStar lists compatibility with boats and marine devices, making it a marine-focused option for buyers who want a black control and do not require an engine cut-off switch in the listed package.

The trim switch supports engine-angle adjustments from the control, while the polypropylene body distinguishes this model's material specification. SeaStar lists copper for the contact material and boat and marine devices for compatibility, providing useful context for a marine installation. The included components identify a black Xtreme side-mount control with trim switch, but do not list a key switch, cut-off switch, harness length, or specific engine family. Those omissions make existing wiring and control-system requirements important when selecting it.

Skip it if you need a listed engine cut-off switch; SeaStar CHX8051P includes one alongside its trim switch.

Boat owners seeking a black SeaStar side-mount control with trim functionality should consider this model when its wiring suits the installation. The supplied details do not identify a specific engine family or harness length.

#10

10. Teleflex CH2100P Sail Control

• Weight: 4.8 lb

Best for: Compact sailboat helm control.

Why it ranks #10: Its compact single-lever, dual-action design is described as suitable for sailboats and space-limited applications, not as a broad outboard-engine control.

Its compact construction and single-lever, dual-action layout make the Teleflex CH2100P a space-conscious side-mount option for sailboats and other tight helm areas. The listing also describes it as a drop-in replacement for controls sold by NW, Onan, TX, Vetur, and Volvo, giving replacement shoppers named reference points.

A single lever performing dual action consolidates control into one compact unit, which the listing specifically positions for sailboats and applications where space is limited. The stated drop-in replacement references provide useful starting points for owners replacing controls from NW, Onan, TX, Vetur, or Volvo. Teleflex lists a 13.1-by-5.8-by-4.3-inch product size and a silver, classic style. The supplied information does not specify a harness, trim switch, or engine compatibility beyond those replacement references.

Skip it if you require a listed trim switch and five-meter harness; POWEROB TEC 881170A13 specifies both for its four-stroke 14-pin control.

Sailboat owners and buyers with limited helm space should consider this compact, single-lever Teleflex when its named replacement references apply. It is not the specified choice for shoppers needing a listed harness or trim switch.
