This isn't the first one I have replaced. Seems like every time I try and run my boat at home I have to replace the impeller. I bought a whole water pump kit again, don't think I'll even try and start it at home again, I'll just run it at the lake tomorrow.
Okay I will check that. Currently I am dealing with a disintegrated impeller. Water pressure isn't good at my house not sure if that's a factor. First one was jammed up and the belt wouldn't rotate. Had been meaning to replace the belt anyways so got a new one and still nothing. Pulled the water...

Hmm okay. It's one of the only things I can think of that's actually different from before the swap. It'll be a few hours before I am able to update with what ecm it has.
It doesn't have a tee fitting it just went straight to the fuel unit. It was never connected the entire time I had it, so is that 2 to 3 psi enough to cause issues?
Okay I will update when I have a look at one. If it helps it will rev up in neutral easily enough. Also not sure if this matters or not. There had been a small rubber vent line coming out of the bottom of the throttle body that didn't seem to go to anything, when I put the motor back in it...
I seem to recall seeing about 25 psi on the rail with the key switched on but engine off. I never thought to look while I was under way but next time out I will check it. A previous owner has installed a fuel pressure gauge on the rail somewhere along the way. Next time out I will have someone...
