runs great Doug at Dixie is awsome recomend him to anyone..

Island Hopper does yopur Formula chime walk any after 80mph..mine seams to get a little squirly up there can't figure out why yet..

Re: 496 Durability?
 

CT,
No, I am not having any chine walking. Are you turning your props in or out? Mine are turning out. I believe, if I recall corretly the drives should be towed in 1/4" at the prop shaft. Do not know if this will make a diference or not. Formula sets this from the factory. Check with them for the exact measurement.

mine have 150hr of 80% wide open throttle and doesn't miss a beat ! I Love this motor!
