Yes we are running 3300 rpm at WOT now and do not plan on raising it with the tuning. Eric @ OJ props has been helping us with prop selection.

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.

We ran the 14x20 prop last weekend. It gave us a bit more mid range but no additional top speed. Eric @ OJ props has been nice enough to send us a 14x15.5 to test out. We will be trying it out this week.

15.5 isn't going to give u any more speed especially going from a 20 pitch

You should talk to robert at nettle props he can help you out and add insight on the setup. He will work with you on getting it right. deals in acme and OJ so he knows both brands well. whats the elevation that the boat is used at? what is boat overall weight any ballast or just running around empty.

The Boat is inside for the winter. For the last trip of the year we turned the RPM up to 3700 and it worked well. Top speed is around 40mph full of passengers. Eric at OJ props is going to send us out a 22 pitch prop to experiment with. Plans for 2014 will be to ad an electric selectable side exit exhaust cut out so we can hear the turbo when we want it heard. Finish hooking up the mechanical gauges so we are not relying solely on the digital gauge. Also we will be adding as much ballast as possible to see what the wake can do.
