Rickson1 1 #1 Posted October 2, 2017 Will I be able to put the 20hp onan from a 93 520H into a 95 520H without any problems? Share this post Link to post Share on other sites
cleat 7,058 #2 Posted October 2, 2017 Should be no issue. I put a 16 HP from a 416 onto a 520 and vice versa. Everything still worked properly. 1 Share this post Link to post Share on other sites
