View Full Version : Engine Overheating
I am currently purchasing an 1986 Catalina 30. It comes equipped with a 21 horse diesel. The motoer starts to overheat at 2800 rpms and it has a three blade prop. I was wondering if the cooling system is plugged or if the three blade prop screws up the engine temp and torque. This diesel should be abl eto handle 2800 no problem but it does not.

I'd check both your cooling system (first) and if there's nothing wrong there, check your exhaust system. We had an overheating problem but it ended up being a rotten muffler. Good luck! LaDonna

i installed a new exhaust system about 4 months ago.air got trapped in the system during the installation.this caused my overheating problem.i ended up spending the better part of a day bleeding the system.you might try to bleed the system thru the petcock valve atop the thermo- stat.if that doesnt solve the problem try flushing your cooling system and if this still doesnt solve the problem check the muffler.hope this helps and good luck
