    WOT

    No issue going up to recommended WOT rpm . How long you leave it there is up to you. As others have mentioned I routinely go wot for fairly long spurts, they are designed to take that. You do want to make sure your prop pitch is correct in that the engine can get up to its wot range. This...

    Need to determine best prop for weird setup

    You would need a 13 or maybe 15” prop to get the rpms right When I repowered my boat with a larger engine, I kept the old higher numerically gear ratio drive and went up 2” in pitch and it works ( 1.81 drive vs 1.62). As mentioned above double check tune up Of engine. Would have expected 4”...

    84 3.0 Exhaust Riser Gasket Leak

    As others have stated there should be no water in there. Did u drain it before removing the elbow? Were the mating surfaces flat filed flat or belt sanded before new gasket went one? Did u check the manifold for leaks ? The crack Repaired is obvious sign of freeze damage did u check it for...

    Mercontrol cables

    Doesn’t answer your question but my neighbors 1969 StarCraft had that same control hooked to a 110 hp 4 cyl and I believe MC1 drive They had bought that boat new and replaced it in 2010. Got a lot of use skiing daily, had a valve job maybe complete overhaul in late 90 s , one stress crack on...

    Mercruiser 3.0 prop suggestions.

    No that is fine, more or less equivalent to a Black Max from Merc. Everybody used to use rubber hubs for decades until swapping over to the insert style hard plastic (delrin). You are fine with what you have. If your engine is in good shape drop to a 13 and you are done.

    Mercruiser 3.0 prop suggestions.

    yes down in pitch dont sweat the diameter if staying with same type of prop. make sure engine is in good shape as suggested. Probably a 13" will get you into 4500-4600 range which will put less strain on the engine. Are you currently running a basic aluminum Black Max type ?

    MerCruiser 3.0 Runs Poorly As It Warms Up

I also play around with old stuff too ultrasonic was a game changer for...

    MerCruiser 3.0 Runs Poorly As It Warms Up

    Use a spark gap tester to see if you are loosing spark from when it first runs to when it runs poorly. Is choke fully opening ? You say you regasketed the carb - did you clean it out in an ultra sonic cleaner ? When it runs like crap open the fuel tank fill cap- wonder if the tank vent is...
