Macgyver 90 #1 Posted February 7, 2017 Ok I have a chance to get a 416-8 with a 48" deck cheep no engine. My question is can I drop in a spare 16hp engine I have from a 416h or is the engine drive pulley different? Share this post Link to post Share on other sites
oldredrider 2,547 #2 Posted February 7, 2017 The engine drive pulley is larger on the hydro. Eight speed pulleys are readily available. Share this post Link to post Share on other sites
bmsgaffer 2,043 #3 Posted February 7, 2017 I think you will need a different belt guard, but you could just throw it on as is and you will go a bit faster than you used to. Oh and the only direct swap will be kohler -> kohler or onan -> onan, otherwise you will need more bits and pieces (engine mounting plate, wiring, etc) to make the swap.
