Re: Stus-List Overheating as high RPM only

It must be something to do with that area. We sucked a fish into the engine water intake while anchored in Smuggler Cove, running the engine to charge batteries. I'll keep the crushed taco chip idea in mind. Jim Watts Paradigm Shift C&C 35 Mk III Victoria, BC On 11 May 2015 at 22:42, Rick Rohwer

Hi Russ, I don’t know if sardines eat corn chips, but I love a good ceremony! After this incident, I was very suspicious of the moon jellies when we were anchored in Prideaux Haven. They looked very suicidal! Do they go for corn chips as well? Thanks for confirming this crazy behavior. It w

If all else checks-out it could be load related as well. If your prop has variable pitch it may have gone to an over-pitch situation. I've also heard that a very dirty hull can increase drag enough to overload the engine / make it run hot. Good luck with it. Francois Rivard 1990 34+ "Take

If you have a heat exchanger, that could be getting clogged. Open the end/s and look at the tubes. Sea water flows through these cooling the coolant. Over time they plug up and need to be cleaned. I use a long drill bit and doubled up 0.040 safety wire, then a bore brush.  Doug Mountj

Re: Stus-List Overheating as high RPM only

Read an article recently on impellers looking perfectly fine, but the "fins" had become detached from the hub. The drive pin did not go all the way through the hub to the rubber fins so it allowed the hub to slip inside the fins. So impeller may look absolutely fine, but not fully functioning.

Stus-List Overheating as high RPM only

We did a run last weekend to a local harbor for the weekend. Wind was fluky and it was a short trip so we were motoring. Alera has a Yanmar 3HM35 with around 700 original hours and was running fine at our usual cruising RPM of 26-2800 on the tach. The hot alarm went off and I let her cool do
