normal temp 160.was trolling temp went to 240. stopped fishing increased speed went back to 160.
changed impeller,ran boat temp 160. next day went fishing temp 160 on way out,slowed down to fish
temp back up to 230. stopped fishing ran back in temp down to 160. went home now changed
termostat and water pump. ran boat in driveway temp stayed at 160. anything else that could
be the cause of high temp or do I have the problem solved? I thought the temp would go up with
speed but went back to normal at high speed and went high at trolling speed which is 2 to 3 miles/hour.
thanks for any suggestions.

The water going in needs to be able to go out. When were the manifolds and risers changed last?
