    I did not check the to see if pressure dropped on the stumbling. I will hook up my pressure tester and that that this weekend. Also I was told if I add any other filter other than the simple inline filter mercury runs it will restrict flow. And I change filters a few times a year. At least 3...

    Thank you for all of your help! I will be cleaning the injectors and fsm by this weekend. Another question. You do not think my symptoms sound like more than junk clogging filters and screens? Like a bad lp or hp pump or fuel regulator? Or I have been reading about shift position sensors?

    1974 302 Holley 2barrel

    Thank you Scott. I have been reading and it seems like the fuel pump I have will have a built in fuel filter? I didn’t know this I just changed the inline. Can I get a good reading on the fuel pressure without the boat being under a load?

    I have a 1974 302. I had the carb rebuilt about 2 months ago. Ran great for about 20 hours. Now it will start and idle great. Run great going slow at lower rpms. Get to WOT soon as boat is getting to plane it dies. Replaced all filters, fuel line, anti siphon valve, spark plugs. And still does...
