Engine trouble overheating.....

[Gramps]

My buddy has an 03' 210 with less than 300 hours on it, he was at the river 2 weeks ago when his boat overheated. He checked the engine compartment and found a lot of water, after draining the bilge he noticed that the lower hoses had been blown off of the water pump. He re-attached them and was under way again and the boat ran fine for 30 minutes or so until it overheated again. He again checked the engine compartment to find more water in the bilge, he again drained the bilge and checked all his hoses and they were all ok. After 10 minutes the boat shut down again from being hot and there was water in the bilge, he started the motor and found he was leaking water from the risers really bad and he said the boat made a sound that sounded like a blown head gasket.

My question is if he had water in the bilge up to the mid point of the motor and a valve was open when the motor shut down could he have gotten water in the motor somehow? What other damage could have been caused and what could be causing the boat to overheat so much and what could be pumping enough water into the bilge for it to fill up so fast? He told me the amount of water coming in from the riser gasket area wasn't that bad but it was leaking all around each risers.

Any thoughts or ideas would be appreciated.

Thanks, Gramps

RE: Engine trouble overheating.....

Could the muffler be blocked not allowing water to pass through. Alot of water passes through the risers and out through the baffles when under a load. If there is a water restriction there I can see that with that much pressure building up, something would have to give. If the muffler has gotten hot in the past the fiberglass could be breaking down inside clogging things up kinda like a large hairball in a drain. I don't know though thats just a guess. Keep us posted. Also if that were the case that could have been the sound he heard. With that much pressuer building up the fiberglass may have busted on the muffler causing the bilge to fill even faster. Good Luck! if it is those run about $500-$700 if it is the 330, not sure about the gt40.

RE: Engine trouble overheating.....

first check id do as far as the headgasket idea goes is check your oil and see if it is milky...if so then your getting water into your oil passages which could be a head gasket, but could be a something else. But that is usually a good first check

If the hoses were not on the water pump there may be a damaged impeller in the pump now as well.

From Gramps' "buddy":

"The exhaust risers are clogged with rust causing back pressure in the cooling system. This back pressure found any water line that was not extremely tight to fall off. When I removed the riser from the passenger side, there was also a small hold between the water jackes and the exhaust. Water was forced into the exhaust portion. When the boat was shut off, water was able to flow into the cylinder causing hydrostatic lock. New risers and the problem should be fixed."

good to hear its solved!!! I was thinking a cracked block or a blown frost plug, I've seen boats fill with water from this. Never a good time telling someone they destroyed their motor, actually aside from being the owner there are few things that feel worse.

Is it safe to guess this boat was run a lot in salt water and not flushed? An 03 should have nothing of sort of rust described.

[Gramps]

Yep it's safe to say that.....

First 2 years of my friend owning the boat it was run in salt water almost exclusively.

My concern for him now is the water in the cylinder causing the hydrostatic lock. Could there be more damage not seen?

He plans to take off the risers and just change them out along with the impeller that was fried.

What do you think????

I am not a motor guy, really. However, it should go without saying that that much dough spent on a boat should warrant a little more care. He is going to have issues throughout his cooling system. Water pump, fittings, everything. I would go through all that stuff now, or it is going to chisel away at him one at a time. And every time is going to be that perfect day on the water.

Bummer...

BTW: Gramps, you have the sickest wake. Ever.
