Re: advice required
That can be caused by hull design but more likely it is how youare trimming the engine out.
If the drive is trimmed out to much(lower farther from the boat) it tries to lift the bow but it is too heavy so it drops, this cycle continues until you trim down.(lower closer to the boat)
Try lowering your trim a bit when it starts doing that, tabs would probably help too but see if you can get it to go away by adjusting the trim first.
