Engine overheat
Have a '89 and the port engine has an overheat problem. White smoke (steam) comes from the engines at 2500 rpms and higher. Have changed out risers, thermostat, water pump, cleaned out intakes, etc. Anyone have an idea???
Maybe at 2500 rpm whith the bow in the up posistion you are not getting enough water to the engines. On my boat the temperature rises in this range but no over heat. just a thoght change trim tabs around in this range to see if you get a temperature diffrence
OVERHEATING
IS YOUR WATER PASSAGES OPEN IN THE ENGINE BLOCK OR YOUR HEAT EXCHANGER IF YOU HAVE ONE. YOU CAN USE MURATIC ACID IN YOUR BLOCK IF VERY CAREFUL. THEY RUST AFTER YEARS OF USE .
