Shouldn't cooling water on center rise manifolds go directly out through risers instead of back to thermostat housing and then out through risers?...
On Doug Russell they call it "shutter-water". It's a non return valve that keeps water from getting into engine via exhausts when you for instance...
Maybe I'm misunderstanding what you mean. Attached is log style manifold and riser (poor quality). On this you have one hoose on riser and one...
Doesn't have to do that and depends on how big crack you have. What happens is that exhausts from combustion chamber is pushed into cooling system...
Do as I told you. Put transparent hooses both before and efter engine and take your boat for a run. If you only have bubbles getting out of...

I have a VP 271 C (Chevy 350) with 290 duoprop drive. The last times I have been out with the boat I have noticed that the power trim have become...
If you have the "octopus" cooling system where water from exhaust manifolds goes back to thermostat housing and then out through the risers you...
Thats a smart idea. I suppose you mean that you would find the heating spot making the problem? Am I able to find for example a crack in a head...
CarbonKen I aint an expert, see my thread "Cooling problem Ford 302" where you have been giving me your thougths (thank you), but can you be...
I pulled out the engine, cleaned and inspected it (lots of dirt). The head gaskets didn't look good, the "metal rings" around the cylinders had...
I aint an expert, but did this just happen? Where all sparkplugs wet? No earlier starting problems with engine? No choking of engine at start up?...
Just for information. I checked on Doug Russell and with 4 bbl instead of 2 bbl I will get 215 hp instead of current 188 hp. If I swap camshafts...
