will 3hp honda work on grubee gearbox???

Hey out there! I was wondering, I plan on building a motoredBicycle with a with a honda engine on a grubee gearbox and mount. i was wondering if instead of using the recommended 2.5hp Honda GXH50, if i could use the 3hp honda gx100. Will it destroy the gearbox? will it fit on the gearbox? heres a link to where i would like to purchase the engine from:
