Maybe someone has ideas....

I've got an old Merc 500 that I love. Always runs, etc. The pee stream out the back isn't flowing lately. I've tried to check the water pump, and it seems to be working. When I run the hose flush attachment and pull the water pump flushing plug, I get plenty of water. The hose and n ipples from the block to the outlet are clear of debris. I even have the water jacket cover off, and for the 5 seconds I could bear to risk running it this way, the block seems to be getting water too.
Do these things have a thermostat that could be stuck? Seems in the past it always peed right off the bat without warmup, but I might be wrong. Is there anywhere else that could be clogged that I can get to without tearing into the powerhead?

HELLLPPPP!!!

We have an old Merc, and the only time that we had a condition like that we replaced the water pump and it fixed the problem. If you need any parts, or a jet pump in excellent condition I am going to sell a parts motor. My e-mail is [email protected] Good luck!
