    Wayne,

    I have been going over parts here, and I think that you will pretty much need to sacrifice 2 motors, to make 1, or use a whole lotta parts, which we have as well.

    We need the 35hp swivel brackets and exhaust housings, with the cowls for cosmetics. Then basically a whole 40hp powerhead long block, with everything attached. Need to use the 40hp gearcase as well. Unless there is a way to swap out the drive shaft? If there is, I have a stash of 40hp drive shafts to use.

    Another thing. I have done this before, and am wondering if I did it on the Lark you now have? I wonder if that is the motor I put the 40hp powerhead on? I remember having to gut the gearcase as I said, I wonder if I did to install 40hp components in it to accept a 40hp drive shaft.

    I dunno, my memory sucks, but that Lark may have a 40hp powerhead on it already.
