Re: Trouble with a new Waco pontoon
Boomyal is right on. Although most toons do have the 20" shaft, yours is obviously in need of a 25" shaft. Keep on them about it and you may get an upgraded motor for nothing. Dealer is the place to start. If that doesn't get it, go to Waco and complain to them. Nothing will fix it outside of a longer prop shaft or a larger, heavier, 20" shaft motor!!!<br /><br />By the way, mines a 70 HP 20" shaft and if the water is Really rocky, it will ventilate too. Not a big deal for me, but on occasion it does happen.<br /><br />Next time you have it in the water, look down at the cavitation plate and see how far it's under the water when sitting still with less than a half tank of fuel. Take pics, too. May help in explaining your problem to the dealer. If it's near the surface just sitting there, it's wrong. The only time it should be at the surface is when you're running full out. My sis-in-law has this same problem on her toon. Needs a longer shaft and it's an 88 HP Rude. As soon as you get to less than half a tank of gas the prop blows out on every little wake. What a pain! Nice boat, but I hate running it because of this!
