Andy, when you said in earlier post you may have to go for long shaft, is this because of what waverunner is refering to,

obviously the installer of the engine thinks this is ok. but wouldnt this put more stresses on the casting. the reason i ask is that originally i put a deposit
on a 150 verado x long, but in the meantime mike at osprey had alredy cut the transom for a long shaft. when i contacted bill higham and told himwhat had happened, he said it was allright to lift the engine up 3". But after seeing another thread on here about bill higham, im curious to know if his oppinions are correct.

Ps nice seat backs, im having some new ones made shortly with the osprey
emblem stitched on.

Did I say I might have to go for a long shaft? Must have been a very early post as I had the deposit paid on the XL DI since May.

Mike makes his EL transoms 27" high as outboards run best on the Osprey at 2" above the planing wedge. I had him cut mine to 25" as I wanted the option to fit Alloy props and wasn't completely convinced about a prop running so high. The reson for the gap is that the outboard is mounted 1.5" higher based on the information Mike and Roy gave me. The offset is 1.25" to Port.

I can't see how you could run an Extra longshaft outboard on a longshaft transom. The outboard would have to be mounted at least 5" higher just to get the Cav plate on the outboard level with the bottom of the hull. You might then need to increase this gap by at least 1" or 2" higher to get maximum performance. That's 7" above the transom

If I recall correctly, you were talking about the auxiliary

the point i was trying to make is, does it matter that the engine is not sitting
supported on the engine bracket, but is soely supported by the bolts and the weekest point of the casting. or should the gap be filled with some kind of
wedge.

No all the strength is where the bracket bolts to the back of the transom, my etec is a normal long shaft and to get the anti cav plate 2" above the wedge I have about 3" between the top of the transom and the underside of the bracket.

Yes, all the weight and force of the outboard is taken by the engine mounting bolts, however you cannot raise the outboard by too much as the mounting points for the bolts will become too close and will have an effect on the strength of the installation.

In my experience Longs are much better on 5.8 & 6.2 Vipermax's you can never really get the height with an Extra Long while keeping the centre of gravity low enough.

Suzuki insist that the gap should be filled with hard wood, Merc & Mariner don't mind.

Wouldn't have thought that Evinrude mind, because the DI's generally gone bang before the 20 hour service, not giving the mounting time to crack.
