A hull with that power to size/weight ratio that runs that aired out must have props that are balanced/blueprinted. Not sure if any of you have tried that at all. A stock mercury 'lab' cleaver (before the CNC props) will not be properly balanced. Unbalanced props will cause the boat to go into a chine walk if it starts porpoising at a high rate speed because the footprint on the boat is smaller at 110+ and unbalanced props may cause the boat to pull to one side, then it will toss to the other side=violent chine/death walk.

Glen with the 37 Talon, I am running 17x33 5 blade mercs I dont know if they are the cnc props, I think they are, I need to go down in diameter, they dont pull as hard as the 17.5 33's! I dont have but a hour on the fresh set up so I dont have any real #'s, I ran around 110-113 with the 4 blades last year and one of the motors was weak.

Now I remember Glen------Good Luck at "ROCK THE BAY" and I hope your boat runs great for you, we will attend the offshore races here in PT. Pleasant this weekend.

4 blades seems to be faster up top.

I would think with the quad step combined with the ventilation holes blowing air under the hull that a 5 blade would have more bite, seems like the boat has to much transom lift and is loosing bit and hunting up stairs, If I had a solid bit with the water and or clean water to continue to propel the boat foward this problem would not exsist, Or at least would not be as bad, I could be totally off! "Thats just my thoughts"

All I won was a trophy for best rigging! One of my boys did win the 10K though and his brother took 4th! All good.

That's interesting, I heard the opposite... And also thought the reason they stopped making the quad step 37's was due to handling issues/roll overs/spins??

Media Master, a cut down 37' single step with 6's and big power doesn't porpoise or chine walk.

MTM, also a single step runs over 100 mph and no chine walk or porpoise. (bravos) I've been on it a dozen times... pulls real hard.

There was also another 37' with 1200's on #5's...forgot the name, it's in Long Island... no porpoise or chine walk... single step.

I have also ridden in other 37 single steps that rode very well. I think Lets Rock just had a very high x-dimension. Because it was very fast for 900's, just not the most stable boat I have ridden it.
My understanding is that they quit making the quad step for the same reasons. Which would also stand to reason why it rode flatter. Flatter, meaning less skeg in the water, especially in turns. It was a great ride though, in fact I tried to buy one after the poker run.

The boat ran 110 with no problems the other day, I dont know what is beyond that at this point, much better with 5 blades, There is plenty left and I plan to see this weekend, I think the boat handles very well but I dont try do U turns when the hull is packed with air! The boat never had a porpoise problem, Just over that 110-113 mark, I will spend some time and start documenting settings and see what happens.

Sounds like a great ride, as was the one I rode in.
