Working with Eric and OJ is great but I feel you are missing a huge opportunity by not consulting the guys at Acme Marine. I have tested a number of props and finally tested one from Acme this summer and it their prop made a noticeable difference over the others I was testing. I would recommend at least giving them a call and potentially trying one of their props.
