DHD has the same set-up without the problem.

most likely due to console arrangement .. offset is an issue, but when your flying .. ballast distribution is everything I find

Yep, that was my thinking, but he said it behaved the same at all levels of trim.

I disagree. They're not the lightest of 5.8m boats.

Hehe well lifting the motor worked on my 5.8 a couple of holes , but it scared the bejesus out of me before that, but then it just cavitated too easily after the lift.. and I couldnt corner as hard .. I vote for ballast + pies + teenagers everytime

Thanks for all the replies... Info is a week late due to the weather, but here we go.

The engine is offset 1inch.

The Cavitation Plate is 1 & 1/4inch Above the hull line.

The prop is a Mercury Lazer II and is a 19P... and has 48-16544 on it.

There engine is fitted with 1 inch to spare on the top of the transome.

Downhilldai... is this the same as yours ??

To claryify... It dives left, regardless of trim...

I'm now thinking, move the engine accross by 1/2 or maybe 1 inch and down by 1/2 inch maybe 1 inch.

You thoughts please !

Just spoke to Roy at Osprey (very very helpful) He suspects the engine may of been hung too low.... I've got a few more measurements to take this weekend. Basically I may have to lift the engine 3/4 to 1 inch up.... watch this space.

Is the offset in the correct direction? ie when looking from behind is the engine 1" over to the right of the boat?

Does the hull have a drain plug fitted? is there any water in the hull that could be unbalancing the rib.
