No wonder he gave it to you.as said it will only fit a 15 transom.. (not your boat) and old heavy weight like that will on fit a very limited amount of boats.. if you cut the transom you will have just hacked half the value of the rib. go and get a proper engine to suit.

Can someone explain what the big problem is with cutting the transom, I don't see the issue if the engine is to remain on the boat long term.
You potentially reduce the free-board height at the transom, and all the potential issues that are likely to arise. Insurance will probably be an issue going forward, considering the boat will now be modified.

The 40hp 2-stroke standard is still desirable or some SIBs, namely older-style Zodiacs GTs and Futuras. Sell the Evinrude and by a long-shaft outboard, job done. Either that or search out the original seller!

So the only down side is a bit of loss of freeboard and potential insurance issues?
Come on ffs it's a rib you get a bit of water over the stern so you drive away and it drains out!
It's been modified is a problem? have you read some of the threads about refurbs and upgrades, people change their boats a lot more than dropping the transom a few inches and don't give it a second thought
The original seller gave him the engine so I guess no joy there!
The boat will be fine with a lowered transom.
my boat is 3.6m and has ample freeboard even loaded with 2 divers all the kit and a driver & it's never sunk, if we leave it in a marina we drop the trunk if it rains we get 50mm of water on the deck the rest runs out the trunk
I'd assume the op is on a budget seeing as he was given the engine so his most cost effective way to go boating is chop the transom a bit of glass over it & go boating
Even if he wants to fit a long shaft later it's not a massive job to rebuild just look at all the Sr 4 rebuild threads almost every one has replaced the transom

Considering the OP bought the outfit, not fully understanding that the engine wasn't right speaks volumes. What's he going to do, take out his junior hacksaw?

I don't doubt it will be fine. That's just my opinion.

Would a four blade prop help with this problem. And yes know that the shaft length should be long and not the short shaft on. Just a thought

Thanks for the information guys.
I've had nothing but problems with this rib.
The rib is great but came with a 13.5hp which was boring obviously.
Found this 40hp which was sat in an under build and possibly for years.Even though it looks tatty the mechanic says it's done hardly any work and the compression is spot on.I had to buy new throttle control box etc and after that it still doesn't go like I thought it would.Gutted really as this has taken months to sort out.
Don't want to cut the transom so will just potter around till something else turns up.
Do you guys think this motor would fit on an old fletcher arrow because I know someone selling and it's probably cheaper and easier than finding a new outboard.
Thanks again

This is the boat I could buy. Are they any good and would the motor fit it?
Thanks again

I don't see your reasoning in buying another hull to fit the engine to,when you have the answer for almost no cost?
A Fletcher may be a short shaft transom but will almost certainly be inferior to the rib you already have
why not alter the rib to fit the engine at zero cost and go boating?
If you get the jigsaw or grinder out you could be on the water in a couple of hours instead of searching adverts for a hull to fit the engine or an engine to fit the hull
Surely the answer is marry together what you have?

It does sound tempting.
I'm more than capable of doing it but would it weaken the transom?
This motor must be 150kg+
