I've seen a small Fletcher speedboat have the Port side nearly go under because of being dead centre. When it was moved an inch to Starboard it was perfect.

I've seen a 6m Searider run with its port sponson permanently in the water. Raising the engine an inch sorted the problem.

Rule of thumb is try a smaller pitch prop and ensure your not overevving by doing so. Then lift the engine an inch. Lastly move the engine or engines to Port.

I was taught that the SR5.4 had an offset console for more room on deck and a place to put a casualty. The ones with the speedboat layouts didn't really suffer by not being offset.

So,I think that another reason my boat (XS 550) leaning a little to the left,
is the asymmetry vpad at the transom as you can see at the photos.
I wonder why it's less from the left,that mean for me less lift from the left.
XS 550 transom.
As I mentioned before, the engine (opti 125) has right shift installation,and despite I lift the engine one hole,and trying some other props I had the
same results.
So,i plan to try another option,making the asymmetry vpad just symmetry.
Already I have construct a wooden mold,which I plan to fit with sika just to see what would happen.
If it will work I will make a permanent fiber construction.

Your opinion please.

Sorry, but of brain fade in my comment. If you need to you should move the engine to Starboard, not Port as I said earlier. DOH!
