Rib/engine rating

Hi, I have a 4m Sea Rider and have replaced the old 50hp outboard with a newer 40hp four stroke with trim and tilt, the engine appears to be too heavy for the boat as there is a tendency for water to swamp over the transom when stopping even when being cautious. is it possible the engine is too heavy for the boat? what could I do to prevent this happening.

Has the transom been cut down?
It should be straight across the top.

Hi,
It isn't straight across the top so yes it must have been cut down

You could block the flooding hull to allow the boat to sit higher at rest
Plenty of older 4 m boats are short shafts so not a problem in itself but obviously with the Sr flooding hull it reduces the freeboard
Lots of boats will ship water on shutdown if your not carefull you just need to come off the plane slowly or blip the throttle just before the wave comes over the transom

But that will probably have minimal impact on "pooping" (when your stern wash comes back over the transom after you stop.

Thanks Guys for all your comments, Blocking the holes in the hull had crossed my mind however there is a dean hole in the back of the boat which drains in to the space below the deck and then out of the large hole at the back.
May have to exchange for a different boat.
Thanks again for all your comments.

Just block the drain hole there should be an expanding plug to do it and drain via elephants trunks
Seems a bit extreme to change the boat for a fairly minor problem
We run a 38'hard boat and can flood the decks on that if we power off too hard
As poly says not much going to stop it other than being carefull

That was one of your more informative posts Poly and it's cleared up a bit of confusion for me - or at least I see the stern talking to that I got from Mrs willk in a different light...
