    top end prop for a 20' lake and bay boca grande

    new to the forum, hello all!

    what props do you guys recommend i try on my boca grande/300 hpdi series 2? i have a 26 and 27 fury that push me to 80mph, and offer great hole shot. have a 29 tempest that will touch 83mph, with a slightly delayed hole shot. anyone have this rig and have tried a pro et, or any other prop that has a better top end?

    Welcome
    your prop choices are pretty good so far! Sounds like time for a tweaked prop. I would just start borrowing props 3 and 4 blade and see what works. I have no personal experience with your rig. My fastest prop so far is a 29" SRX by DAH.

    The new Merc Promax prop might be a player.

    It will all depend how much and what type of lift your boat will like as to what prop will work best. Since you did well with a Tempest, I would try a Yamaha T1-29 next. It will give alittle more stern and overall lift and might give you better numbers. Then having it B&B and possibly adding cupping to fine tune.
