Sometimes when motoring my engine stops pumping raw water. It stops coming out of the exhaust and it sounds like the water lift muffler is dry. I take it out of gear and rev the engine a few times which seems to kick start the flow but stops when it drops back to idle. If I get it flowing and immediately shift into gear and get the revs up, it seems to pump ok. I checked the impellor(new in May) and checked the raw water strainer and both seem fine.
My thoughts are possibly a small air leak in the feed side(seacock to raw water pump intake) of the raw water system that lets air in when at low rpms. Any other ideas?
The Engine is an M25xp.
