I have a 2002 sundancer 260 5.0 bravo with 250 hours. Just put in new risers, manifolds, alternator, water pump. Took boat out and was running well then about 5 minutes into trip and moving at about 4000rpm warning signal goes off showing high temp!! I shut off engine and let it cool down. Then started up and cruised for 30 minutes at about 2500 rpm and boat ran great , no high temp. Then got closer to home base and ran it up to 3800 rpm and again heated up, lowered to 2800 rpm and it cooled down. Does anyone have suggestions as to why it would heat up at 4000 and not 2800?? Thanks so much.
