Need a little more out of my Yamaha 130

[dpf-01]

Guys, I need a few more ponies out of my 1994 Yamaha 130hp 2-stroke. I know Yamaha produced a 140hp using the same block, does anyone know if a 130 can be upped to a 140 with bolt on parts?

10 hp will get you 1 mph. and the parts will be prohibitively expensive unless a blown 140 lands in your lap.
