Finally after 13 months my boat is headed back into the water. During her time on the hard the engine was only run long enough to siphon antifreeze through the cooling system. Now I want to check out / service the engine before the yard puts her back in the water.
The engine is a Yanmar 3GMD. This model doesn't have a heat exchanger just raw water cooling. My question is this: Should I be concerned about using pressurized water,(from a hose) applied to the input side of the raw water
pump while I'm checking things out?
Once I know the engine runs satisfactorly, I'll wait until she is back in the water to complete the maintenance.
