Islander is selling an engine lifting bracket on this Forum for a 100 quid, seems a better option than carving your new transom.

more speed

Raise your motor 5 to 10cm.(watch your water pressure)
Buy a good stainless prop.(makes a big difference. try a mirage+
pitch 17-19)
Your problem has more to do with your prop than hight of your motor. Believe me I know.
A power lift is also a very good option.
Then you do at least 5-10 more knots.
greetings,
Niels

You can buy an engine crane for less than that!

or you could even hire an engine crane for a few days from a desent hire centre !!! after all what the hell do you want with an engine crane after your engine problems have been sorted out ?

Boat now sorted

Evening all,

Many thanks for the suggestions for how to sort my problem.

I have now had the transom top trimmed by 25mm and lowered the engine by one hole of adjustment - 20mm and the boat is back in speed demon hooligan mode.

Perhaps my new transom was just built higher than original.

My transom builder carried out this work at no charge and the charge for removing and refitting the engine was 1.5 hours on top of the cost of an engine service.

Now a happy bunny.

Duncan

Raising the engine too high can slow the boat down more because you can't raise the bow enough without the prop blowing out. A decent SS prop would probably allow you to run at the higher transom setting without losing bite. It also sounds like you might get a bit more top speed by shifting the CG back a bit so you don't have to run with so much engine trim to get the bow up for max speed. As ever, the downside of that would be that it might take slightly longer to get on the plane, however depending on your current setup this could be a good compromise, down to your personal requirements really.
