Hi, i have just carried out a sea trial on a sealine f33 1999, with twin kad 32's. On the sea trial i found after about 15 mins both engines had a temperature of around 110c whilst revving at around 3500 rpm. The engines have covered 478 hrs and look very clean. They haven't done alot with the previous owner, he has barely used the boat in the 3 years he has owned it. Has any one got any ideas why these engines are running this hot?
Im thinking it could be due to lack of servicing as the impellers haven't been changed out on quite a while is my suspicion.
Thanks Gavin
