Give it a go. I asked this question on my 9.8 tohatsu long shaft and some said no. It's fine you may not get top end a couple of knots shy cause u get more drag with a longer shaft in the water. Don't know about the shape of you yam leg but I get a bit of water overflowing in with the long shaft but isn't that bad and I think it is a Tohatsu issue

Your sib should use a short shaft as that is what it is designed for, at slow speed it should be ok but don't forget that the leg is longer in shallow water.

If you want to use your boat on the plane obviously you will be putting more strain on the transome and also the trim will be effected so I guess you will need to trim all the way in, but it still may ride high at the bow.

If it's only going to be used on a sib you should really get a short shaft, AJ is only trying a long shaft as he also uses his as an auxiliary engine for his rib.

One more thing, you need to check with your insurance company that everything will be ok and you are covered.

Hope that helps....
