Now has name and "port of origin" plus flag and is performing well. Still has a leak and I think the engine tends to run hot. I'm considering changing the original 3-bladed prop for 2-bladed one as I'm told that will cause the engine to draw less power from the battery. Does anyone have any experience with this sort of mod?
Liked by DaveWhittaker and BOATSHED and
It's a racing prop and will use lots of power hence the heat.
As you have a cabin cruiser it does not need such a coarse pitch prop and changing to a prop with a lesser pitch will improve your running time and produce less heat. Performance will depend on the chosen prop but should not be much different from what you already experience.
As you already have a water cooler inlet and outlet you could just wrap some copper tube round the motor and connect with silicon tubing to keep the heat down
