I have this engine in my seagoing Fisher 34. It’s the original 1979 engine. 1800 hours. I bought her in 2016. The exhaust was a total rebuild. Have serviced her yearly since and she has run smoothly. Noticed several perished connectors including that from water cooler to engine. That perished last trip out, last week, noticed engine overheat, switched off and we were towed back. Are there any experts on this type of engine who travel to Dorset to repair in situ? Would be happy to pay for an assessment.
