The PS screen on the fuel pump. It had a little gunk in it, and not that much but apparently enough to hinder the pump. I thought about the fuel pressure and I may end up having to check that. I also read about these fuel pumps not working as well below 1/4 tank and I have about 1/8 of a tank in there currently. I didn't want to put too much fuel in in and have it sit all winter, bc I am not sure how many more times I will be able to use the boat this year.
I didn't think about the tranny cooler. I just have to locate it now. If it is set up like the PS, then it should be on the stbd side.
