2003 Yami Vmax 200 3.1
Had this motor rebuilt about 4 months ago. Overheats every time you come in when at idle. Replaced the impeller and no difference. Never did this until it was rebuilt. Any ideas?

Debris in pressure release valve. Its partially open. Clean or replace with a new style mushroom head valve, like the one in a 3.3L hpdi.

Did you replace just the impeller or put a complete water pump kit in.

Just the impeller. I thought the housing might be bad. ?

did you fix this? I have the same problem on vmax hpdi 175hp

Check the rubber o-ring where it slides up onto the tube inside the lower unit housing.
