If your engine is the same model / stable mate of my Tohatsu and it has the same 15hp carb I don't see why the upgrade wouldn't be possible.

Thanks for the help but I think my engine was the block which was made for the 9.9, 13.5 and 15 hp and is less cc than the current model which is a 15/20 hp. Mine I am told has less cc than the current model.
