Seafarer 38c - Fresh water leak and steam from engine

[edbolles]

Hello Seafarers. I have a 1979 Seafarer 38c and love it. The marina did not winterize properly and now my fresh water system is leaking most of the holding tank into the bilge. The leak is between the engine area and bathroom. How hard is it to replace hoses? Yesterday I ran the engine for 3 hours and found steam in engine compartment and the bathroom. I shutdown the engine and seemed very hot. Ideas? Are both issues caused by the water leak?

The plumbing leak should be simple to trace and repair. The engine is a different animal. No temp gauge on the engine? Any leaks from engine?
