    Need to determine best prop for weird setup

    weather you swap uppers or props verify the tach is accurate. Also would do a sanity check on ignition timing and engine tune up (carb/fuel system/ignition components). Check total ignition advance at like 2800 should be 24-28 degrees or so. Not saying this is the root cause but not getting...

    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”...
