So I just replace the Impellar, Started the boat using a Fake a lake I noticed there is very little water coming out the Exhaust.
Then it starts to heat up, If Rev it up it seems to Cool down. I rev it up and water is coming out with steam
Also there seems to be alot of Steam coming out of the Exhaust and the manfoldsare much hot then I remember. I basicly burned my hand when i touch the top of one of them.
So I start pulling hoses. The hoses that go to the Bottom of the Exhaust manfold has alot of Brown scale in it??.
I cleaned that out.
The hose come from the Top doesn't seem to be Hot and there is no water in it ( or very little ) when I take it off.
So could the be a Clogged thermostat ( i hope) or a Clogged exhaust manafold??
Enginer is a 2008 5.7 Black Scorpion with 190 hours.
Any help would be better. suppose the be leaving for a trip next Tuesday
Any Ideas is some I can Take apart to Check??
