Question

I have a 91 12.5 hp `lawn mower. Can i put a 11.5 hp enigne on it? They are both vertical shafts. Will evrething hook up great to the other enigne?

Answer 1

You really should take a long look at your conversion and make your own decision.  You didn't specify if the engines are the same make.  The difference in HP probably won't make much difference but, are the shaft and or pulley sizes alike or are you going have to buy more pulleys/blade hubs?  Will the throttle and choke controls change over without modifying?  Can whatever electrical wiring you have be converted?    Are mounting bolt patterns the same or can the body/frame be re-drilled without causing weak points?  Some things to consider.

Answer 2

as long as the mounting bolts line up, it will be fine

Answer 3

as long as the belt is not off center and it mounts up no problem
