Bob,
Your set-up looks great. I tried to install a set of Gibson's on my Flame a couple of years ago, but they were too long and wouldn't fit around my external steering. Looking at your pic, looks like you got around that problem by attaching them with 4" wet exhaust hose. What is that hose lenght? Are the turndowns angle cut on the bottom, like the Gibson's? I think the angle cut was to prevent reversion when in reverse. What length did you end-up cutting them @? Have you tried them yet? I'm really interested in doing this on our Flame, if you could give some details, I would greatly appriecate it. Presently, all I have on our boat is internal flappers and Salibury external flappers.
Thanks,
Dean
BTW, SWEEEEET Looking Flame, what speeds are you seeing with her? I bet whatever speeds she's running, it's only a matter of time, til you start tunning her up!

I tried a set of labbed 30" props this weekend and was able to get 76.6 MPH(gps) at 4700 RPM. It was running 73.6 with stock 28's before with approximately the same load and weather. So, I need to find a set of labbed 30's. Keep in mind this boat has the 496 Mags, not HO's.

I've got about 4 hrs running time with the tips. I cut them straight across at the bottom, but I'm going to recut them at more of an angle. Right now they actually tuck under slightly, so if I were to lose power while running at speed water could conceivably be forced in the exhaust. They do quiten it down a bunch.
