Cooling water ways

Removal of deposits
At idle water is sucked up through the bottom of the leg via a rubber impellor and circulates though the top of the engine to cool the cylinders via a thermostat. When the boat is moving water is forced in to the cooling system by the action of the water running past the engine. Only a small amount of water is expelled from the tell tale the rest goes back down the leg.

Deposits (e.g Salt and Calcium) build up inside the engines cooling water ways over time. Engines should be periodically stripped and cleaned to prevent overheating. Always flush an engine after every trip if possible to reduce this. Removing deposits may require removal of the powerhead, head and cylinders depending on the make a model, and as such requires some expertise.

This impellor shows the results of an engine being started without water. The rubber impellor quickly melts, but providing the engine hasn't overheated the leg can be removed and the impellor replaced.
Check your thermostat

This thermostat has been neglected as the engine has not been regularly serviced. A blocked thermostat will prevent cooling water reaching the head and cylinders. Overheating of these areas quickly results in catastrophic failures, and very expensive repairs.

Never leave fuel in a engine
Engines that are stored with fuel in may experience issues with fuel lacquering or jellification. Carbs need to be stripped and cleaned in order to remove.

Fuel can only be stored for a limited period of time. Engines may run intermittently on water contaminated fuel leaving the owner in a compromising position and a long way to row.

In the ocean sand is everywhere. Sand and fuel systems are not a good combination. Periodic cleaning of carburettors and fuel pumps are essential and part of a regular service programme.
