I'm negotiating a 1982 Catalina 30 with an Atomic 4 gasoline engine that is raw water cooled. The survey was today and found only one major issue.
The engine overheated in the following way. Engine started and warmed up to about 160 degrees. Ran for 10 minutes at idle. Adequate cooling water discharge was observed. Surveyor shut down the engine for 30 mins. Started the engine. Warmed up to 160 at idle. Engaged forward gear and opened throttle to about 3500-4000 rpm. The engine overheated with temp spiking over 200. Shut down engine. Some soke from engine compartment and surface reading on the engine head were 210-220 at various places.
Any ideas what cause the overheating with cooling water flowing?
Every other aspect of the boat was solid.
Thanks,
KBG
