    Much better, I agree. Mine was 1 hole too high from factory (parker-yamaha powermatched) as there was ventilation and porpoising. All solved lowering 1 hole.

    He won't need those tabs with the new motor height. They were installed trying to compensate for the motor being too low.

    Just took my new-to-me boat out for the first time, and noticed it leans starboard right as I get on plane. I've read that this can be solved by just powering through and them trimming up, but this goes against every common sense bone in my body. "Oh your boats listing when under power? Just go faster!" Maybe it'll work, or maybe not. I'm going to try shifting it up and hopefully this helps. Thanks for the video!

      Hey Harrison, check out our other video on adjusting your steering tab. That may help with your leaning issue ruclips.net/video/Zg-490RA-c4/видео.html

      Is the helm on the starboard side?

    • @Steve-yh1pj
      @Steve-yh1pj 2 года назад +1

      If it's a deep v hull, it's quite common with one person on board for the boat to lean to the side the driver is on. If it's just steering starboard could be torque steer and you might consider hydraulic steering. Regarding engine height check first that the top of the cavitation plate is level with the right part of the keel first before adjusting there are lots of videos around for that.

    It’s funny I have had a Yamaha 30 2 stroke for about 20 years , then I decided to upgrade to a Yamaha FH four stroke brand new 2022 . Both outboard motors lined up bang on my 20” transom to the keel lining up straight off the keel . I just picked up a brand new 14 ft. Same exact hull as the last boat however, I went with a mercury 25 new four stroke and it sits 2” below the keel . Measures the shaft length and its 22” shaft 🤔. I went looked at other new ones and are the same22”. Yamaha ones are 20” . Why is that ? . Now I need to raise the motor above the transom to avoid that spray and drag I’m getting. Or maybe go back with a Yamaha FH25 FS

    Does raising the motor changes rpm? I have a 115 Mercury pro xs with a 19p stainless steel prop only getting around 4800 rpm at wot.

      Yes, it usually goes up if the height is incorrect.

      Maybe you need 2 drop on your prop pitch if you want to raise you rpm on wot. So maybe check 17 pitch prop.

    I'm facing similar issues. New to me skiff style double hull. Has a 90hp 2 stroke Yamaha. She squats bad and had exceptionally terrible hole shot. I've been told that my motor is too low & my prop is bad. The ventilation plate is exactly inline with the bottom of the hull. My motor sounds sluggish like your first trial run did too. I'm thinking both things may be the problem for me, but I'm not sure which order to address them in to get the best result. Any advice?

    @charlesstiles8904 Год назад

    Cavitation plate needs to line up with the bottom of the hull. That's the starting point. After the boat is loaded with gear and people then you adjust it up according to the water line. Cavitation plate should just be submerged.

    I have a 16’ Wahoo (Whaler copy) that is mounted as high as it can go. The only solution I see is drilling new holes for the lower mounting bolts. The lower unit is about 2 inches too low. Thoughts?

    Could you maybe help me, on a Boston Whaler Dauntless, I have a 150 Optimax, but on the right of it a helper motor 8hp, Since the boat has a V hull, the right side is higher (or transom is shorter) what would the correct height be for the outboard engine? Should the cavitation plate be on the waterline? Thanks.

      With the boat on plane and properly trimmed the anti-ventilation plate should be skimming the surface of the water, not above it.
