Several things could cause this issue, but my first hunch would be to check the thermostat.  However, during a diagnostic procedure, I first check fluid levels, then raw water operation.  Check seas strainers, raw water pump impeller and make sure the seacock can open and close freely.  If all that is good, then I start checking fresh water components.  160 seems a bit on the cool side to me, and I'm comfortable at 200.  220 is when I start getting concerned and 240 you are doing damage.  But the quick and easy, see if your thermostat is stuck open.  Good luck and fair winds.

Pearson 365/367 Mechanic Shop / Overheating

Last post by Capn - September 03, 2025, 03:35:02 AM

I have a 1982 Pearson with a Universal Diesel 44 HP. It is a Kubota block. I recently installed a new heat exchanger. I can run the engine at normal cruising RPM for 2-3 hours and it never overheats (runs about 160 degrees), but when I stop for an hour or so and restart the engine, the temperature will spike to 200 or so. If it sits overnight, it won't spike the next morning when I restart it. I think I am getting an airlock in the system but don't know where it is coming from. Any thoughts or ideas?

Okay, so now I have learned that PeteW whom I purchased #6 (Tartanic) from, was an avid poster on this forum. I have read every post he ever posted, and understand everything now, knowing he is an Avionics Engineer. I am blown away by his ingenuity and effort he has put into this boat. I knew I was looking at something that someone put some serious time into, but I had no idea to this level.

That said, I am also dumbfounded now at how so much of his work actually works on the boat. And, how or if any of it will be easily fixed if needed, because it is so custom.

I have tried many ways to reach PeteW to no avail. I wish I could have a consultation with him to learn some things about this boat. If anyone is still active on this forum and has any recommendations, please advise.

Just purchased Tartanic (name will change) here in San Diego. Boat is in great shape, and I can't wait to get to know her better. I am reading all the posts here nightly to get up to speed on this boat. Looking forward to learning more!

Greetings, I have signed up, I can login, but every time I try to make my first intro post, the system says I have the letters wrong and the riddle answers. I am using Safari 18.5 as my browser. What in the world am I doing wrong?
