    No crank trigger. Distributor doesn’t look great but maybe that’s normal for marine engines. Looks like the weights and spring. Only setting on the 6al is rev limit. Here is the prop

    Thank you Glenn, that is a great bunch of info. I’m guessing it’s possible the tach has the error if anything, but i would imagine the differential between the props should show on the tach even if it’s not exactly accurate, though I am assuming. Truthfully I was worried about driving the boat...

    Sounds like the bravo 24 may have more slip then causing lower mph? I’ve got the carb out for rebuild now. I was planning on checking all the plugs and base timing when I get it back together, I’m a fuel injection guy by nature, but the advance is set in the distributor with the weights correct...

    Also I found out the carb is a 1000cfm Holley to my surprise.

    221 Vision with 496 BBC prop/speed help

    Forgot to get back to you guys. I was able to try a merc bravo 24p prop from a local guy. We got the motor turning 5000rpm at top speed with it, 200rpm higher than before, but it was only doing 68-69mph in the same conditions. Seems odd that it would turn higher rpm but go slower. It also felt...

    Thank you guys for the detailed responses. I do not know what the gear ratio is, it is a balanced roller cam motor with forged internals. It has a Howard cam. Sorry for the rotated photos. I can’t figure that out on my phone. Do you guys have a link to an example of a prop you think would be a...
