Hi Benc;

A whole new engine but i dont think Yamaha has a couter rotating 115hp.
I can be wrong, will check on Yamahas homepage.

I was wrong, they have counter rotating in 4-stroke.
Than i would guess that the engines are to high, my old boat had 2 X 300HPDI and only 8,2m long boat and my wobbeling came around 59-60 knots.
I lowered the engine and it disapered but than i got the galopping effect instead.
But the boat was a little over powered, with 2 X 250 i would never have the problem.

Hmm, edited as it didnt make sense

Looking at this picture, it looks as though I already have one counter rotating engine, as it looks like the propellers spin opposite ways.

Yes it`s a counter rotating, it`s really hard to se on pic but they maybe look little high.

Have you tried putting extra weight on bow before you adjust engine height this will help

Give Barnet Marine a call and ask them. Laurence Lock is your man, he knows all there is to know about Tornados

Thanks for the suggestions guys, I tried to go down and try adjusting trim today - but when I got there found my battery was flat so going back again tomorrow night hopefully. and this weekend is meant to be nice so will play then if not.
