So the Repowering is done. I'm suspecting +\-300 hp. The cam is rated idle to 5 Grand, which I think is a good redline for me.
Using a tweaked 3 blade SST 14.25x21 the acceleration to 3000 is very good-then the cam and carb really come on and the revs jump like afterburners are lit. At 5200 rpm I throttled back. GPS MPH was about 62.
Figuring I can pull a 23" pitch, a custom shop let me try an OMC Cyclone 4 blade 14x23 tweaked. Wow, awful. I lost 700 rpm, lost a few mph top end, and got chine walk at 58-59 mph as a "bonus".
At at his point I have 2 options: keep the SST and mind the tach, or buy a new more recent design prop and try to pick up some mph.
We're headed to the River soon so I could use some input.
Thanks folks, John C
