I have one sitting on the bench right now. I am planning on a little glass work on the gear mount plate.

I think the ply mount will be OK for a 90 2 stroke. Mine is getting a soft mount and a YS 1.20.If you are really oried double it up with lite ply and laminating resin and don't forget to add triangle bracing.

I would be interested in any other info on the model.

I am planning on a re-cover since the covering has lifted since I bought it and won't stick back down worth a hoot.
