"2005 model 90hp. overheated recently due to lots of floating seaweed, motor shut down to idle, after it cooled down throttled up again and immediately heated up. Idled back to boat ramp, Flushed engine after use, runs fine but now gauge measures about 1/4 hot all the time. Impeller or t-stat clogged with weed? Thanks."
 
I am experiencing an overheati

I am experiencing an overheating problem with a 1988 90hp. At first the buzzer was going off at high speeds - so I cleaned the heads and water jacket compartment and changed the water pump. Engine now runs at proper temp at high speed but still overheats at low speeds?
