I've spent a few days researching now, so I feel adequately prepared to finally ask this question.
Quick background:
Bought this boat 2 weeks ago. It's a 2001 Glastron 5.0 Volvo/penta I/O. It overheated on me once in the water, which I thought was because I sucked up some reeds. I pulled the stern drive up, found no reeds, lowered it, temp went back down, trucked right along all day. Slow speeds, 45mph, etc. No probs. Ran it 3 more times, each time I would flush it thoroughly.
I pull the boat in on the trailer, attempted flushing, water wouldn't come out. It just sprayed out the sides of the muffs. The engine begins to over heat with the muffs on. If I flush water in the port on the side of the engine, it runs cool all day.
Now, I have pulled the thermostat, replaced it, verified that all passages are clear (including the bypass port). I also pulled the raw water pump and saw that it was, in fact, brand new. No leaks, it pumps just fine.
So I begin wondering if I can get flow up to the engine, so I pop off the intake hose (at the raw water pump) and run flushing water to the stern drive. No water.
I ran to Lowe's , made myself an adapter and ran water from the inlet hose (still disconnected from RW pump) and watched in amazement as clean water flowed out of the inlet holes in the stern drive.
Water still won't make it up to the pump. I pulled the clean out cover (yup, I found that one) and it's clear.
So... help?
