I have a 1988 mercruiser 4.3l engine (Alpha). Im planning to video the problem in hand. It runs fine but when facing the engine the hose off the left side of the water pump starts to boil water inside and expands.Its boiling from the lower end of the hose. Everything is brand new parts for the engine also the engine is new. Any ideas?
