prop size for 140 zuki

[Jon G]

My 20' came with a 20 Suzi prop and it only topped out at 5700rpm (bottom of the WOT rpm range), I switched to an 18 and now it revs to the max 6200rpm at wot and is much more responsive with a beter whole shot and better fuel economy the 20" pitch was borderline for my boat boat the 18" is perfect. Fully loaded heavy boat will just make 6200.
