    Unfortunately the pictures don't quite show the "bad" pods issue, what is it ?

    Just that they don’t provide enough floatation. They have a beveled edge so there is no room for trim tabs.
    Plus the kicker and kicker bracket make it impossible for trim tabs.

    A few people have suggested a lighter motor and getting rid of the kicker. An extension pod would be cheaper then swapping to a lighter motor. I also need that kicker motor.

    I'd suggest trying a bolt-on to the cavitation plate lifting device, the rectangular ones seem as good as any, more in-trim for the engine, and see what happens, if the resting trim of the boat does not concern you.

    I believe the resting trim is of concern for Connor.

    How much to extend the pods is just a guess without more information

    If those existing pods are foam-filled, are you sure they aren't water-logged? Even closed-cell foam eventually can get water-logged. That could potentially add a lot of weight to the stern.

    If that's the case, I'd remove the foam, rebuild the existing pods so they are hollow and watertight, and add a drainplug to them (this is how i have a boat set up).

    What kind of waters are you operating in? If they are calm waters, you can keep the pods (existing or new) even with the bottom of the hull, essentially lengthening the hull. This will provide the greatest stern-lifting effect, but also keep you from raising the bow when waves get high. OTOH, if you run in high waves from time to time and would like to raise the bow in those conditions, then you will want the flotation pods to sweep upward toward the rear, so that the transom becomes the pivot point in the rocker.

    Good point about the foam getting waterlogged, worth checking that.

    @DogCavalry look familiar?
    Pretty sure I saw this boat on your dock last weekend...

    It does. But what on earth is he compensating for with a 300 verado on a 23' boat? How about a 150 evinrude? I wonder if he ever got it solved. If he's my neighbor, I'll go look.

    This is the motor the boat came with. It’s always had 250-300HP motors on it. It’s a very heavily built duel hull with a pilot house, a 150 would not be capable.

    Unfortunately the boat pod has not been addressed yet, house renos and a global
    Pandemic got in the way. I’m going to be working on the pod in the fall of 2024. I’m hoping to get in contact with a marine architect or someone who is experienced with this type of job, I’m hoping to show them the boat in the water this summer so they can see how it’s running.

    I’m still open to any suggestions, and if you know a marine architect or pod builder I’d love to get any recommendations.
