Overheating M35-B

[emoney]

Ouch, I think that prop (and shaft for that matter), MIGHT just scratch your leg if you go near it...lol. Little critters get into everywhere. Buy hey, I need to go under mine this weekend as I fear the same sight.

Most times the thru hull is reachable from hanging over the dock, if not just a mask and holding your breath.

Use a steak knife sideways and on an angle (pulls the critters out) to clear it out. The strainers will catch anything that stays loose inside.

If you are getting water out the exhaust in an amount consistent with your boats history it is unlikely a raw water supply problem. Check the coolant thermostat and clean out the heat exchanger, check the coolant pump and belts. Generally a fouled prop will cause overheating only in a system that is having or about to have other problems, as it has little effect of the cooling systems ability to remove heat.
