I just got a good deal on a 1971 SeaRay.<br />WHen I got it home I found milky oil on the dipstick. So I replaced the headgasket, intake gasket and the carberator gasket. Flushed the motor with (engine safe) solvent. This fixed the milky oil problem. Took the boat out and had a blast (hooked for life). <br /><br />1 week later I put the boat in the river wich was very low, and hit a sand bar.<br />Once i felt the boat slowed down i tried to trim up, but i was too late.<br />when I got passed the sand bar i trimmed down to get up on plane and noticed my engine wich was running very cool was now overheating!<br />I shut the engine down and trolled the boat ashore.<br /><br />I called alocal marina, they told me to put the earphones on and check for water pump failer due to sand getting up in the drive sys. they told me to take the plugs out of the motor and check to see if the lower pump is pumping water up to the engine. And it is. So I know the lower water pump is fine. My best guess is that I have sand in the intake. So I am going to take the head and intake off again to clean an flushout. I should be done in a few days.<br /><br />I guess my question is has anybody mad the same stupid mistake as I and what did it take to fix it? I am doing the right thing, looking in the right area ect?
