ZXT 2,401 #2 Posted June 3, 2019 Was this 18hp engine out of a Horse? If it wasn't, the crank diameter and length might be different. 2 Share this post Link to post Share on other sites

pfrederi 18,719 #4 Posted June 3, 2019 I am assuming the 18 is a Magnum 18 from a 418A (there was no 418 H that i am aware of) Spec number in the 18 should be 24510 if so it will fit. However you will have to do some rewiring and get a new ignition switch as you are going from a battery points to a Magneto system 1 Share this post Link to post Share on other sites
richmondred01 2,307 #5 Posted June 3, 2019 Yes. The m18 Kohler (wheel horse spec) will replace the kt17. Like pfrederi said the wiring will need to be tweaked. The m18 is a great engine. I have seen them with 2500+ hours. 1 Share this post Link to post Share on other sites
