Do you repair marine shifter and throttle controls?

Yes – we repair single and dual-lever marine control systems, including mechanical and electronic shifters. We service stiff cables, broken detents, worn control boxes, and alignment issues to restore smooth gear shifting.

How do I know if my shifter cable needs replacement?

If you feel stiffness, delay in throttle response, difficulty shifting into gear, or the handle moves but nothing engages – it’s likely a stretched, corroded, or failing cable. We can diagnose it dockside.

Can you adjust or realign my shifting system on-site?

Yes. We adjust the cables at the engine end, lubricate the control box and linkage pivots, and realign the system so it engages forward and reverse cleanly. Many shift problems are fixed in a single visit.

Do you service electronic (fly-by-wire) shifters?

We do basic diagnostics and component replacement on electronic shift systems such as Mercury DTS and Yamaha Helm Master. Setup or calibration that needs the maker's dealer software is done by a dealer for that brand, and we tell you when that is the case.

How much does it cost to repair or replace shifter cables?

Labor is $150 an hour. Replacing a shift or throttle cable usually takes 2-4 hours, plus the cable itself and the trip fee; a control box rebuild or a new control depends on the model and parts. After we look at it, you get a written estimate for labor, parts and the trip fee, and nothing is done without your OK.

What causes stiff or jammed marine controls?

Corroded or kinked cables, dried-out lubrication, misaligned shift linkages or worn control handles are the most common causes. Heat and salt exposure can speed up wear, and regular service helps prevent failures.

Do repairs come with a warranty?

Yes. Our workmanship is warranted for 90 days from the invoice date, and new parts such as cables or control heads carry their manufacturer's warranty. Your invoice lists the work and the parts.

Marine Control Box & Shift Cable Repair

Docking is dangerous when you have to wrestle your shifter. We replace seized control cables and rebuild worn throttle boxes to restore that satisfying "click" into gear.

About this service

Tactile Precision

Click Into Gear.
Smoothly.

Stiff shifters aren't just annoying—they are a docking hazard. Whether it's a seized cable, a worn control box, or a misadjusted neutral safety switch, our boat shifter repair restores the smooth, tactile confidence you need at the helm.

Seized Cable Replacement

The most common cause of stiff shifting. Control cables have internal liners that degrade over time, binding the metal core. You cannot grease them; the only cure is throttle cable replacement or shift cable replacement. We route new high-efficiency, low-friction cables for a "like-new" feel.

Control Box Rebuild

If your lever feels sloppy or won't stay in neutral, the internal detents and cams are likely worn. We disassemble Mercury and Yamaha control boxes, replace worn bushings, and re-grease the mechanism.

Neutral Safety Switch

Engine won't crank unless you wiggle the shifter? The neutral safety switch is likely failing or misaligned. We adjust or replace the switch so the engine cranks only in neutral, as it should.

The Repair Protocol.

Diagnose. Route. Adjust.

Isolation Test

We disconnect the cables at the engine. If the lever becomes easy, the problem is at the engine end (linkage or shift mechanism). If it stays stiff, we disconnect the cables at the control box: if the box then moves freely, the cables are binding; if not, the box needs a rebuild.

Cable Routing

Replacing cables is an art. We use "messenger lines" to pull new Gen I or Gen II cables through tight gunwales and rigging tubes without damaging your boat's wiring.

Barrel Adjustment

Precision is key. We adjust the brass barrels at the engine end to ensure the transmission fully engages forward and reverse without grinding or hopping out of gear.

Friction Setting

We adjust the throttle friction screw on the control box so the lever stays where you put it while cruising, but moves easily when you need to slow down.

Common Questions

Can you just grease my stiff cable?

No. Marine control cables are "sealed for life." If they are stiff, the internal plastic liner has swollen or the wire has rusted. Greasing them is impossible; they must be replaced.

Why does my boat grind going into gear?

This is often a "stretch" in the shift cable. The cable isn't pulling the gearbox lever far enough. A simple shift cable adjustment at the engine end usually fixes it.

Shift Smoothly.

Boat Throttle Cable or Control Box? Finding the Real Fault

A stiff lever does not always mean you need a boat shifter replacement. In many cases the control box itself is fine and the problem is a worn boat throttle cable or shift cable whose internal liner has swollen or rusted. Our isolation test answers the question: we disconnect the cables at the engine, and if the lever becomes easy, the fault is at the engine end; if it stays stiff, we disconnect the cables at the control box to see whether the cables or the box itself is binding.

When the box is worn, a rebuild with new bushings and fresh grease can restore the smooth, tactile click into gear. To help us prepare, note your control model (for example Mercury Commander 3000 or Yamaha 703/704), whether the throttle, the shift or both feel stiff, and whether the engine cranks only when you wiggle the lever.

How Mechanical Marine Control Systems Wear

Many outboard and sterndrive boats rely on mechanical marine control systems: the lever in the control box pushes and pulls two cables, one for the throttle and one for the shift, that run back to the engine. Over time the cable liner swells, the inner core corrodes and the ends wear, so the lever grows stiff and gear changes feel vague.

Stiffness that builds up over several seasons usually points to wear along a cable, while a lever that turns loose or sloppy points to worn parts inside the control box.
