Hi Derek and welcome to ribnet.

I'll ask teh questions for everyone although I'm sure someone more knowledgable will ask more.

what make and model is your boat (i'm guessing a 4.1 mtr searider from your coment about ballst holes)?
what engine do you have on?
Is there any offset on your engine?
What is you console arrangement?
what prop is on your engine?

Just as a starting point if you answer these other peeps will be able to help you a lot more.

Hello, and welcome!

I assume you bored the big "dump hole" in the transom out as well?


As a slight tangent thought, are there signs of any repairs on the underside of the hull near the treansom? Mine developed an unnerving list at speed until I took the antifouling off and found a repair near the transom - just not a partcicularly good one, so one side was slightly convex, the other concave! Only became a problem above about 22 knots.

found the fualt the fins were bent on the engine so took them off runs fine now
i have a 40 yammaha with a 12.5 pitch prop its the old style engine it had a single seater console but extended it to a 2 man moved the bat up front took the arial frame off the back n move the tank into the extention in the seat to even out the boat. yeah board the dump hole out i maintain boats alot new there was sumthing wrong with it in the process of fixing my fletcher gts just now the z drive keeps spilling oil into the engine bay its a 3l inboard 140hp will get some pics up soon
