RE: Prop type on your Rio 51
I'm quite happy with the stock set up and I am currently switching to a gas bag tonight for a lower CG as well. I realized early in my research that the stinger could break off in so many ways so I did a mod on the internal stinger and posted it on the original RIO thread so others can benefit from it in not loosiing the wholle prop assembly. Some boats run better without trim tabs, I will keep mine on for now. I understand that you have a full mod zen I will do more research on the 2814 prop for now and see where that brings me.
