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 Formula 242 SS with VP 271 C (Chevy 350) with 290 duoprop drive. I bought the boat a year ago and the power steering didn't work. My...
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...
Thanks, Woodboat
Hi I have a Ford 302 (188 hp Mercruiser 888) in a boat that weighs about 2 ton. The fuel economy isn't that good although engine seems to be...
Is it possible that theese holes are to bleed the air out of the manifolds when engine has been out of water, and if the holes are plugged the air...
Yes, there are restriction holes between manifolds and risers with about 1 mm diameter. What purpose with those tiny holes? What happens if they...
I have tested that with no obvious result because every flow connects back to the thermostat housing on 888 engine. It isn't very logical that all...
Gonzo I don't have powersteering, but thanks anyway. However, I haven't checked the hose between outdrive and stern for possible pieces. I will...
Thanks What is radiator flush? Isn't it enough to just remove the crap out of engine, manifolds and risers or do you use the radiadtor flush to...
