Force Fuel Pump?

[MN_Jack76]

Hello fellow boating friends, I have a 89 Force 50 I overheated last summer on the river and when I noticed and throttled down it died. It hasn't started since, although it "wants to" with the starter spinning. I checked compression thinking I blew the head gasket and got about 115psi on both cylinders (although I don't know what the compression should be). Then I checked and have good spark on both cylinders. So I turned to fuel, I noticed without the connector on the fuel tank, it doesn't "shrink the pump bulb". I took the fuel line off the fuel pump and it seemed to pump fuel very weakly but possibly enough?? I then took the pump apart, but didn't see any tell tale signs of diaphram problems. I Know this is driven by engine vacuum or pressure and put my finger on the suspect (a bracket coming right out of the block), and it seemed to blow a "medium to low" positive pressure until a backfired burned my finger almost off - lol. Any Help by my fellow boaters would be greatly apprecitated!! - Jack

Do you know what caused it to overheat?

I'm assuming I need a new water impeller/pump. I figured I'd tackle that later, I just wish I could get the dog to start first! - lol

Actually Maxum, now that I think about it, I did some lower unit work including replacing some seals and the impeller 2 years ago? I remember the impeller housing was scorn but I cheaped out and also didn't want to wait for and/or drive to get the parts. If I remember right, I checked the thermostat and it was good.
