Cooling & Overheating
Marine cooling and overheating specialists — water pumps, impellers, and overheat diagnostics — because nothing ends a day on the water faster than a temperature alarm.
// Overview
What we do
A marine engine relies on raw or closed-loop cooling to survive constant load, and a single failed impeller can cook an engine in minutes. Overheating is one of the most common and most damaging marine faults, and it is almost always preventable.
We diagnose and repair the entire cooling system — pumps, impellers, passages, thermostats, and heat exchangers — and we treat impeller service as essential preventative maintenance, not an afterthought.
Catching a cooling issue early is far cheaper than the engine damage a failure causes.

Services included
Water Pumps
Keep the coolant moving
The water pump is the heart of marine cooling. We inspect, service, and replace raw-water and circulation pumps so coolant keeps flowing under load, and we check the related passages and connections while we are in there.
- Raw-water pump service
- Circulation-pump replacement
- Housing & seal inspection
- Flow verification
- Passage & hose checks
- Corrosion assessment
Impellers
The cheapest insurance there is
A rubber impeller wears out and can fail suddenly, cutting off cooling and overheating the engine within minutes. We replace impellers on schedule as preventative maintenance and inspect for shed vanes that can lodge downstream and cause further trouble.
- Scheduled impeller replacement
- Shed-vane inspection
- Housing & wear-plate check
- Correct impeller for engine
- Lubrication & reassembly
- Cooling-flow test
// Process
How it works
Inspect
We inspect the full cooling path from intake to exhaust for flow and heat-transfer faults.
Diagnose
Flow and pressure testing confirm exactly where cooling is being lost.
Repair
We replace impellers, pumps, or thermostats and clear any blockages with correct parts.
Verify
A run-up confirms stable operating temperature under load before handover.
