Re: Need help with Bayliner Trophy
its a new engine that I built im just worried about it over heating just not sure about this cooling system that was changed on it the water pump used to be through the hull and pump was on motor.. now pump is on leg smaller pump different volume of water???? it goes through the heat exchanger first and you heat that water up its not cooling your exhaust manifolds and risers enough maybe im just worrying to much
Your risers should run hot enough to be *just* too hot to hold your hand on them.
There have been some people that have had closed cooling using an Alpha raw water pump and had the engine run a bit hot.
The water in the heat exchanger doesn't (or shouldn't ) get all that hot. You could put a temp gage on the riser water supply (heat exchanger discharge) hose and measure it to be sure.
You should be using a 160 degree stat. The engine will probably run near 180 at a steady state cruise. Is this a "FULL" closed cooling system (block+ manifolds)?
What were you cleaning out of your risers?
You have a "new" engine, the manifolds and risers are new aren't they?
