I got one for you. Bought a 40 that was a 3QM 30 from the lakes. Came south here and was retrofitted with Sendure heat exchanger.
So I buy the boat. And immediately notice the temp sending unit is cracked. Go to the parts counter and provide the engine model and get the part. Install the unit and notice the engine overheats a higher RPMs. Start doing the overheating diagnosis dance. Fixed, or replaced everything. Still over heating. In desperatation I drop a temp sensor in the exchanger while running the boat hard to overheat her. "Overheats" at 140°. It then hits me. RWC engine model got me a RWC temp sensor which goes off at 140°. Switched it out. Problem gone. Sent from my Android. Please forgive typos. Thank you. ________________________________ From: CnC-List <cnc-list-boun...@cnc-list.com> on behalf of Ronald B.

Quite frankly I thought fresh water cooled referred to non-salt water.

If you have a radiator cap and glycol coolant then it is freshwater cooled. On Sat, Jun 13, 2020, 23:30 Ronald B.

If you have a 2QM like I do, it is Raw Water Cooled – water from the lake/bay/ocean is pumped through the engine for cooling and merged with the exhaust and expelled.

That thing would shake the entire boat. Some had Atomic 4s I think, which are much smoother, but any original A4 that is not FWC is living on borrowed time at this point. Actually ANY RWC engine from the 80s not in a fresh water lake is.

Owned our 82 for 21 seasons. Absolutely love it. Original Yanmar 3GM which is just the right power (do not recommend a smaller engine) No major design or build issues just issues of being such a tender age :-) Of course get a competent survey of hull rig and all systems. Our main hatch cover had delamination of core as screws around the edge went through the balsa core, they leaked and core rotted. Removed cover, installed solid glass around edges for screws, new balsa and glass, reinstalled. Filled 2 screw holes in deck with epoxy reassembled and no more leaks :-) Sails like a dream. Very sensitive to trim and weight distribution. Races with the best of them need a crew of 6 or 7. Easily cruises for 4. 2 can easily sail her. Is designed for light airs but can handle high winds and seas well. The designer Rob Ball has one - need I say more? Contact off list if need anything else.
