Yamaha 70 hp Mods

[1650HJ]

Im really thinking about pulling the trigger on a 70 hp 2 stroke Yamaha tiller for my Xpress. What all is there out there motor wise for a little more kick.

I know yall sell the heads and exhaust tuner, but what about 90hp carbs. Say if I were to run a 70 with 90 carbs, hydro-tech head, exhaust tuner, and some after market reeds. What would that put the motor around? Power wise?

All this will be going on a jack-plate on a Hyperlift 1650 Xpress.
