I have a 250 HO on a 08 cougar FTD with a 6" hyd plate, running a moderate load. I am able to post some blistering top speeds but unable to find a prop that will give me a great or even good hole shot with decent top speeds. I have a suspicion it is in large part due to the 1:71 gear ratio. I have tried 25, 26 raker II's and merc trophy 25, 26 and tempest as well. All are "ok" when by myself with empty wells and half tank of fuel but with 2 people full wells and fuel horrible at best. I have been working with a couple people with same problems and we have spent thousands of $$ trying to find the perfect prop with no success. I know its not a basscat only problem as I have seen it on rangers and stratos as well. The common denomator is the 250 HO. Anyone else having this problem and if so what was the solution. Any ideas would be greatly appreciated.
