25\" shaft Yamaha hpdi 200 on 79 mast anglr 20
 

I posted this question in the general forum and haven't had much reply so I'll try here. I'm looking to the seacraft guru's and captains for options, short of fiberglassing. I want to bolt up the top set of holes in the jack brackets and motor mount bracket, that are ineveitably not bolted to the transom when putting a 25" shaft in a 20" shaft location. I'm trying to find maybe a bracket or some sort of system that will fasten to the transon and the well for added transom to motor support. With the top holes not bolted to the transom I feel like there is more strain then there should be put on the other bolts and holes. Anyone have or seen anything like this?? Here is a visual aid for my query.

Looks like the "powerlift" jack plate. A friend of mine also has one. On his transom we made up a board (wood and glass) to fill in the void and raise the transom. It was secured by the upper outboard bolts. On the inside he used a square alum backing plate (a thick one-1/4 in maybe) to pick up the 4 bolt pattern. It was aslo painted to blend. I think the addition of the inside plate and the fill board closed up the transom and provided a little more tie in but the "powerlift" is still doing the work here. I think he may also have added bolts through the outboard/lift/transom/and plate somewhere in the middle of the typical 4 bolt pattern (overkill really). I hope this make some sense....he aslo had a strong transom to start with. In the end it looked similar to what Bigshrimpin posted to your orig post.

Yup...thats where my buddy got his powerlift jackplate. Al Gore's internet sure made the world smaller ;) I'll see if I can snag a pic of his boat over the weekend.
