Cooling system service · Orem, Utah
Boat cooling system service — keep your engine running cool.
Overheating is one of the most common — and most expensive — boat problems. We replace water pump impellers, service heat exchangers and closed cooling systems, and fix overheating issues on outboards, sterndrives and inboard wake boats.

- Heat exchanger service
- Thermostats & hoses
- Overheating diagnostics
Why it matters in Utah
Hot summers, silty water, hard-working engines.
Most boat engines are cooled by lake water pulled in by a rubber impeller. Sand, silt and shallow-water running shorten an impeller's life — and Utah has plenty of all three, from shallow, silty Utah Lake to the sandy shores of Lake Powell. Running the engine dry, even briefly, can ruin an impeller in seconds.
When an impeller fails, the engine overheats quickly, and broken rubber vanes can lodge in the cooling passages. Replacing the impeller on schedule costs a fraction of repairing an overheated engine — which is why we recommend checking it every season and replacing it on your manufacturer's schedule.

Benefits
Why cooling system pays off.
- 01
Prevent overheating
A healthy cooling system keeps your engine in the right temperature range all summer.
- 02
Avoid costly repairs
An impeller is inexpensive; a warped head or seized engine is not.
- 03
Better performance
Engines that run at the right temperature run smoother and more efficiently.
- 04
Peace of mind on the lake
No overheat alarms halfway across Lake Powell or Bear Lake.
- 05
Corrosion protection
Anodes and zincs checked to protect metal cooling components.
- 06

Cooling System FAQ
Cooling System in Utah, answered.
How often should I replace my boat's water pump impeller?
Most manufacturers recommend replacing it every 1–2 years or after a set number of hours, depending on the engine. Replace it sooner if you run in sandy or silty water, run shallow often, or the engine ever ran dry.
What are signs my boat's cooling system has a problem?
A weak or missing tell-tale water stream on an outboard, rising engine temperature, overheat alarms, steam, or loss of power at speed. If you see any of these, shut down and have it checked before running again.
Why do impellers wear out faster in Utah?
Sand and silt act like sandpaper on rubber impeller vanes. Shallow, silty water like Utah Lake, sandy beaches at Lake Powell and frequent beaching all speed up wear.
What's the difference between raw-water and closed cooling?
Raw-water cooling circulates lake water directly through the engine. Closed cooling uses engine coolant inside the engine and a heat exchanger cooled by lake water — similar to a car's radiator. Both still rely on a raw-water pump and impeller.
Is it bad to run my boat engine out of the water?
Running without a water supply can destroy the impeller in seconds and overheat the engine. Always use proper flush muffs or a water source when running the engine on the trailer.
Can an overheated engine be repaired?
Often yes, depending on how hot it got and for how long. Stop the engine as soon as you notice overheating and have it inspected — catching it early makes a big difference in repair cost.
