Went for the 20hp Mercury 4 stroke. Cost more but I don't think I'll regret it. Thanks for the advice.

Its was a smooth engine, but stupidly heavy (70kg ?) and it also sat very high on the transom making the boat feel unstable when flat out (something I had never experienced with the Futura even with 40hp on the back).

Well we've taken the boat out for the last 5 days in Cornwall and I have to say I'm suitably impressed. Boat and engine performing very well with no major problems other than scuffing the prop due to launching in an estuary at low water. I do notice, like others have, that there is a small amount of spray back into the boat at three quarters to full throttle and will play around with a small block of wood between the top of the transom and the motor. Anyone else with a similar set up with thoughts on this?

Pretty much accepted and standard practice on the Aerotec, a raiser block about 1" will do it.

Cheers Max. Looking at the set up an inch doesn't seem enough but will try it and see what difference it makes. The cavitation plate is about 4 to 5 inches under the water line at rest.

Problem you will have raising it more than 1" is that the OB clamps* will end up too high on the inner transom plate. If you want to go higher major mods are needed.

Due to the unique transom shape and deep V keel at the rear of the Aerotec engine height set up is tricky, still aim to get the CAV plate approx level with base of keel though.

*Depending on exact OB model of course.

Makes sense and yes you are right the clamps will be out of range of the plate. Will give it a go and report back.

I did not move the plates just got a 1" block painted black and Sikaflexed on. It could maybe benefit from another 10mm or so but I think the 25 engines need a higher raise than the Mercury/Mariner 15.
