you will need to drain the block BEFORE doing the heads. Being that deep in the hull , remove and plug the raw water inlet hose as a precaution
Ok, I knew I had to drain the block before doing the heads. I assumed you said that thinking I had seawater in the block.
Thank you
As you didn't tell us what the engine is or if the engine is raw water or fresh water cooled, anything said is 'generic'.
Rgr...it is the engine/boat in my sig with fresh water cooling.
Thanks
:facepalm: Quite right... Signatures are a bit like EULA, everybody knows they're there, but.... Sorry about that...
As you have freshwater cooling, just drain the fresh water side as you know. For the raw water side, plug the raw water hoses that go to the exhausts (either elbows or manifolds depending on full or half system) and when you remove the elbows, leave the tubes and everything else in place on top of the Y-pipe...
