Boat trailer service & upgrades

The trailer is the one part of the boat nobody thinks about, until they do

Every day on the water starts and ends on it. It carries the whole boat down the highway at seventy, backs into salt water, and then sits for eight months.

We service, inspect and upgrade trailers to the standard work our technicians are certified to.

One

Bearings: the first thing to go

Bearings are where trailers fail, and they fail for one reason. Water gets in and grease gets out.

Serviced to standard

Stripped, races and cones inspected, new seals, repacked, preload set by torque rather than by feel, and the protectors filled correctly.

Or upgraded to a hub built for submersion

Dexter builds two lubrication systems designed to go in the water, and either one ends the cycle.

Vault runs the bearing in a pressurised chamber of marine lubricant that is continuously replenished. The pressure holds water out and oil in, the piston is rated for high temperature, and the wear components are stainless. Less heat and less friction means the bearing simply lasts longer. There is no access hole in the wheel centre.

Vortex runs a completely sealed reservoir of marine‑grade grease, with the rear seals riding on stainless steel wear sleeves so the seal lasts and the spindle does not corrode. The threaded cap comes off for inspection without disturbing the system.

Both are maintenance free, both are built for immersion, and Dexter warrants them for six years. Service kits run from 2,500 lb through 7,000 lb axles, so there is a fit for nearly every boat trailer on the water here.

On a schedule

Booked on a schedule, a bearing gets found in the bay. Left alone, it gets found on the shoulder of the highway with the boat still behind you.

Every trailer gets a road test with hub temperatures checked and recorded before it leaves.

Two

Surge brakes: the ones that frustrate everyone

Anyone towing on surge brakes knows the feeling. Backing down the ramp and the trailer fights you. Brakes that grab on the overrun, or do nothing at all.

Serviced properly

Actuator function tested and bled, breakaway system verified and the battery replaced.

Improved with free backing

Within a surge system, free backing is the fix for reverse. The brake releases when the trailer is pushed backwards, so there is no solenoid to energise and no lockout to remember. Back down the ramp without fighting it.

Superseded by electric and disc

Electric‑over‑hydraulic disc brakes replace the surge system altogether. Braking is proportional to the tow vehicle rather than a reaction to it, discs shed salt water and heat better than drums, and reverse stops being something to work around. On tandem and triple axles it is the single biggest change to how a trailer tows.

Three

Upgrades that make loading easy

• Roller improvements — the difference between winching a boat on and floating it on
• Winches replaced, upgraded and mounted properly
• Power winches, and the electrical to run them, wired in tinned cable with sealed terminations so it survives the salt
• Bunks and bow stop set so the boat loads the same way every time
• Coupler, jack, strap and chains

Fabrication

Built, extended and repaired in our own shop

Tongue extensions

A Salish Sea problem: tidal ramps. An extension is an engineered change — load path, coupler and actuator relocation, brake line and wiring extended to suit. Not a longer stick.

Frame and cross‑member repair

Aluminium I‑beam and tube. Section replacement sequenced and fixtured for distortion control, with the trailer’s rated capacity preserved.

Galvanised steel, repaired properly

Ground back to bright metal well past the weld zone, forced‑air extraction at the arc, then the coating restored with zinc‑rich or cold‑galv. The written procedure is posted in the bay.

Axles and running gear

Ordered to spec and capacity matched, never pulled off a shelf. Alignment, U‑bolts and hangers done with it.

Winch stands, guides, racks, spare mounts and walkboards.

Titling

Trailers that have to be registered

Work that produces a new or unidentifiable trailer goes down the Washington State Patrol path from the first cut:

• No Washington VIN until it complies with WAC Title 204 and RCW Title 46
• A certified scale weight slip is required for the finished trailer
• A return visit for final inspection is required

We build to that document rather than to a drawing, so the trailer can actually be registered at the end.

Every trailer leaves with a written inspection report
