    I own a 1985 MasterCraft Prostar Stars and Stripes with a 351 Windsor....

    The last four (4) times I have taken the boat out it runs GREAT and STRONG for approximately two (2) hours and then all of a sudden it begins to bog down as if it's starving for fuel. It becomes very hard to start if it starts at all. The last time I took it out it would start and then every time I put the boat in gear it would stall....

    After the first time this happened I changed the in-line fuel filter and it contained approximately two (2) inches of black particles almost resembling coffee grounds. I sunsequently changed the entire fuel filter assembly. I soon thereafter took the boat out again and the SAME problem happened again.

    Next, since changing the entire fuel filter assembly, I have also changed the following: entire fuel line, fuel pump, carberator, spark plungs, spark plug wires, PVC value, distributor cap and rotor, and ignition system (replacing the old point system with an electronic PCM kit). In my mind, I thought I have addressed all of the potential items that possible could be causing this problem.

    To my surprise, I took the boat out this past weekend, and the same EXACT thing happened again! Boat ran GREAT and STRONG for 2 hours and then began missing and then stalling and it was hard to start. Again, as in before, if the boat started once it was put into geat it stalled.....

    I hae NO idea what else to look at here......

    My only thought is maybe there is some sludge in the fuel tank that is gathering at the pick up point inside of the fuel tank thus preventing the fuel from being sent to through the system -- and this seems to happen at approximately 2 hours into running the boat which equates to 1/2 of the fuel being expended from the tank..... I have no idea if there is a screen or mesh covering over the fuel pickup inside of the fuel tank....

    I am at a total loss here....

    I would love to hear some ideas and thoughts from some of the members here as to what this could possible be....

    Thanks,

    Ted
