TBH the hull looks cheaply built, I see it's warped under the engine brackets in some pictures.

Not the standard I'd accept on a brand new boat!

Is it manufactured plated and rated (looks like it is in the pic I added) ? Or is it a home build ?

There's your problem

On another subject who's done the rebuild on the motor ? Looks like "instant sealer" to me. Is its compression equal ?

nope its just dirty where it changes color it warp look like it

to tell u the truth i was gonna buy a used complete rib, so went to local guys in cpt who a close friend recommend who does retubing to get a quote jst incase i bought one tht needed tubes, and he had 2 of theses hulls laying there which he told he would tube for a good price. apparently these guys are good because he had loads of pics up in his shop of his whole team working and building boats up in romania and they had pic of nice boats so i went with them, and my buddy has a pretty nice boat which they had retubed

I had a similar engine but less hp on my bullet ski boat. Was a great motor, always a turn key boat and would literally launch out of the water when I hit the foot throttle.

Looks like You have a 25 inch leg, long shaft, but the transom seems to be for a 30 inch or extra long shaft.

Instead of chopping the transom I would suggest getting a transom bracket made up. Google outboard jack plate and you will see lots of adjustable brackets that bolt onto where your engine currently is and then you bolt the engine to that. There are hydraulically adjustable ones from places like Bobs Machine Shop bobsmachine.com which are really good but are very expensive. You could get a fixed one fabricated once you have seen one.

The flat horizontal fin above the propellor is the cavitation plate. That needs to be in a straight line with the bottom of the hull directly in front of it, ie the V part. Having said that, lighter boats with lots of hp are usually higher but you need to experiment. Higher might be an inch or so, not 5 or so like you currently have.

Also if you do a jack plate, the further back you come, the higher you go, but once again only a bit.

Some racers run really high engine heights but you need semi surfacing propellors and a way to get water into the outboard. Too hard for leisure use.

Hope this helps.

Outboard jacks are not designed to compensate for incorrect shaft lengths!

I see it as he has a long shaft (suitable for a 20" transom) and he needs a XL (suitable for a 25" transom). I think 30" would be far too long

5 pages-WOW...lol.

the answer is simple my friend. forget cutting the transom/jack plates etc-sell the engine, buy the right size (about 90hp) and buy the correct shaft length. bolt on a yam 90hp ish and enjoy.

agree with peter-you need an XL

cheers
