Drift Boat & River Sled Motor Repair
River boats take damage no lake boat ever sees — gravel through a jet pump, a skeg folded on a rock bar, a kicker that drowned off Scappoose Bay — and that's most of what we fix.

River boats are a different problem
Everything about running a river works against the motor.
Shallow water means debris ingestion. Gravel, sand and silt go through intakes and pumps that were designed for open water. It isn't abuse — it's what running a river involves.
Strikes are routine, not exceptional. Rock bars, gravel, submerged timber. Lower units, skegs and pump housings take impacts a lake boat never sees in its life.
Silt gets everywhere. Into cooling passages, water pumps and intake screens. A motor run in the Sandy in spring has been drinking suspended sediment the whole time.
Boats get launched and beached anywhere. Which is hard on gearcases, and hard on motors that get swamped.
Motors sit between seasons. Fishing is seasonal, so these motors sit for months — and stale fuel is what follows.
What we see most
Jet pump damage. Nicked impellers, scored wear rings, bent intake grates. On a jet, worn clearance shows up as lost speed while the engine runs perfectly — which sends people chasing engine faults for a season. Jet pump work.
Skeg and lower unit strikes. The skeg exists to hit things first, and on a river it does. Skeg repair — and after any strike, check the gear oil, because the same impact can open a seal.
Cooling blocked with silt. Weak telltale from a blocked intake screen or passage rather than a failed impeller — worth checking before replacing parts. Overheating.
Kickers that won't run. Stale fuel and blocked carburettor circuits after a season standing. Small outboard work.
Drowned motors. Swamped at a ramp or rolled. Recoverable if dealt with immediately and usually not if left — see below.
Prop and shear pin damage on prop-driven river motors.
If a motor goes underwater — read this first
Time matters more than anything else here.
Do not try to start it. Water in a cylinder doesn't compress, and cranking a hydrolocked engine bends rods.
Get it out and get it to us, or get it to a state where we can work on it, the same day. Fresh-water submersion caught within hours is very often fully recoverable. Left overnight, corrosion starts inside the engine and the odds drop sharply.
Keep it wet if you can't act immediately. Counterintuitive, but a motor kept submerged corrodes more slowly than one drying out in air.
Call PHONE. This is the one repair where hours genuinely decide the outcome.
Jet, prop or both?
River boats run all three configurations and they need different things:
Outboard jet — conventional powerhead, jet foot instead of a gearcase. Powerhead work is standard outboard service; everything below the plate is jet work.
Inboard sled — a marinised V8 driving a Hamilton or American Turbine pump. Big power, thin water.
Prop-driven — kickers and outboards on drift boats. Skegs, props and shear pins take the damage. Small outboard repair.
Where we work
At the ramp, at your house, on the trailer, or wherever the boat is sitting. River boats mostly live on trailers, which makes them among the easiest to service — no dock access, no moorage paperwork.
Service area · how on-site service works
Before the season
River motors sit through winter and get asked to work hard on day one, often a long way from a ramp.
Worth doing before the first trip: fuel system and carburettor check, impeller, gear oil (and a look at what comes out), pump clearance on jets, skeg and prop condition, and a compression baseline.

FAQ
Do you work on drift boat and sled motors?
Yes — kicker outboards, outboard jets and inboard jet sleds. River boats are a substantial part of our work.
I sucked gravel through the pump. How bad is it?
Depends what it hit. Nicked blades can often be reconditioned; a scored wear ring is a replacement. Worth inspecting before the next trip, because a damaged impeller cavitates and cavitation accelerates everything.
My motor went underwater. Can it be saved?
Often, if we get to it the same day. Don't try to start it. Call immediately — hours matter more than anything else.
Why does my jet boat feel slower than it used to?
Almost always impeller-to-wear-ring clearance rather than the engine. More here.
Can you meet me at the ramp?
Yes, and it's common with river boats.
My skeg is bent from a rock bar. Does it need fixing?
It affects handling, and the strike may have done more than the fin. Check the gear oil — milky means a seal opened. Skeg repair.
Do you service the kicker as well as the main motor?
Yes, and it's worth doing both at once rather than discovering the kicker is dead when you need it.
