in-line 6 overheating problem

[moneyhole]

Destroyer,
That's where I'm lost. There was no water at all in the 3" round tube and no water in the manifold when I opened the drain. I do know they used the old engine's thermostat when the swapout was done. Could I have dual problems.... engine T'stat not opening at set temp and have a bad stern drive water pump impeller pump at the same time? I'm just speculating at this point. Thanks again for any knowledge shared...it's making me crazy

If you pull the inlet hose like I told you you could see if the lower unit pump is working. Like most have said it is probably the raw water pump, buy one and install it for good measure if it hasn't been done in awhile.

I have never seen a 3" exchanger on an inline six. You have any pics of this motor?

There is a pic of the motor on my album page, but you can't see the 3" round exchanger too good in that pic. I did measure it and it's 3" in diameter. I bought a complete stern water pump kit today...drained the lower unit just before the sun set and the grease/oil most lilely had water in it. It has that funky smell and is olive colored. If I reading the manual correct, I should be able to pull the lower unit without removing the prop. We'll see how it goes and pray for sucess!!
