I photoshopped one on my boat when they first showed the 225. I thought it was going to be hideous. I ended liking it. I will post Later.

So, it they can flash a 4.2 liter V-6 SHO to 347 flywheel HP. How much will they get out of a 4.6 liter V-8 when they break the code? Any guess on peak HP and Torque?
I did not see a sportmaster listed for a gearcase
I like the look.......The old Square Box V6 Opti Pro XS has aged.
Now, where does one get a Performance Tuner so that you can HEAR that V-8 Rumble when on the Fly :)

Its says the 250r is 520lbs but the 300r is 512lbs..
Over on S&f supposedly the 300R went 103 on a bullet 21. 6400 limiter. This motor could be the ticket on a Xb 21
Those Pro XS and R Series engines sure sound good.

Not sure I see the correlation between the prop price and speed. I have and have tried $1000 props that get out run by the stock Promax. If I had your magic Promax I could be even better off.

When I ran the 32 Promax, 32 Pro ET and the 32 CNC prop they all ran the same speed on the rev limiter at 99 mph. We went with a 34 CNC prop because they don't make a 34 Promax prop or a 34 Pro ET.
