But if it ran hot...

    I have a 1984 , 150 hp black max. Parts are available and fairly cheap. I have replaced the stator, trigger, cdi boxes, water pump and so on. Compression 125 psi on all cyclinders. Just hard to crank when the temp is below 40 degrees unless you have the fast idle in a certain place. On a 17'...

    90 hp carb over filling

    Onboard tank supposedly had a leak, original owner used a portable. Would have to cut the floor out to remove the tank to check it. I aint doing all that for sure. Could be a fill hose leak or a fuel line, thier is only a 4" hole in hull to change the fuel level sensor. The boat is a 17' scout

    90 hp carb over filling

    Hi They were torqued 10 inch pounds . When i took them apart the first time after i bought the boat to put in kits they were so tight i thought i was never going to get them out with a screw driver. I thought about the high gas tank pressure also, it was the plastic EPA non atmospheric vented...

    90 hp carb over filling

I think by squeezing the primer bulb till its firm is pushing the rubber gasket out of place. Fuell pump pressure depending on rpm is roughly 1 to 2-1/2 psi. Who knows what psi the primer bulb...
