I have a 1987 searay 268 with twin 470"s. The starboard engine runs fine at apx. 148 degrees. My port motor overheats. I have just put in a new impeller and complete housing kit (Gaskets and housings) It still over heats, but not as fast as before. I have been doing a LOT of reading here over the past 3-4 weeks. I have also changed the thermostat. Ran it w/o the thermostat to no avail. I am pretty much mechaiclly inclined. Need to know whats the next step(s) to take to cure this issue. I do know about the 470"s and the issues with them. I have not let the motor go past 200 degrees, as I am aware of the issues that may arise with this motor. Amy/All help will be appreciated.
