The biggest difference is going to be hull length. Chop the rear off your SJ and shorten the pole, thats 99% of an aftermarket freestyle hull. Shorter boats are easier to get into the air. They are also more difficult to plane and riding fast usually means you're bent over. Lightweight guys...

All freestyle boats need to be short in order to get the nose up and to rotate quick enough to complete a flip. This configuration is "very" difficult to ride around like long OEM hulls. Manufactures have made "freeride" hulls that are somewhere in between, usually with no rocker at the rear...

You gotta put some water in the exhaust! The ringing in your ears is a dead giveaway.

Everyone got rich at the same time. It will likely turn around just as fast. It seems like I can only find good deals when I'm broke.

I have weighed some square nose SJs at 340lbs range with gas. There was one RN there but I forgot what it weighed. I have worked on a ROC hull that had the same problem you are describing, It had an old R&D race engine and a Hooker 10-16. As I remember we increased the pitch a little and the...

How much forward speed does it take to keep the pump from going flat? I have had skis that would do this at zero speed but were fine with any forward movement. It seems like large hub impellers are more susceptible to losing everything at once where small hubs fall off more smoothly. Adjusting...

A lot of these "templates" are a little too wide and too flat for good ring life. I recommend doing some research and drawing your own with a better closing radius at the top.

I've had grate bolts that broke through the inlet shoe cause the pump to blow out at low speeds. I consider Protec nozzles at 85mm to be very good, they seem to work great. Your problem is commonly caused by an excessive pressure drop somewhere in front of the impeller. A .quick test would be...

The most accurate advise on jetting? Whats in my carbs probably won't work in yours. Learn how to tune!

Tune the top screw using your tach on smooth water. Set it at the rich side of peak rpm. Then adjust the pilots, then recheck the top screws. I suspect your pilots are too small, how does it sound at 1/3 throttle? Each step in pilot size makes a noticeable difference. Mains aren't nearly as...

A good picture of the bottom and the pump will tell a lot about its overall condition. Fortunately for sellers, buyers don't seem to care.

A stock 61x cylinder doesn't have enough exhaust port area for 7000rpm. With a pipe, 62T cylinders run great. They just lose low end response faster than 61x cyls so getting the pump right is more critical.

The USA is good to go as long as the petrodollar is a thing. When that goes, winning an old fashioned WAR is the only way to maintain dominance.

Rider height and weight play a big role in determining how long a ski needs to be since you stand behind the center of gravity. Little guys have no problems with shorter hulls, big guys really struggle getting them over the hump.

Excellent, your full throttle mixture is correct. Now your pilots need to be just rich enough to provide good throttle response, it will probably need to sputter a little at 1/4 throttle. Considering your impeller, the rpm and top speed are about right for a low port cylinder with a wet pipe.

I use single line cooling with no problems. Make sure the elbow at the pump has a 5/16 inside diameter. I usually have to upsize the fitting. From there the entire line and fitting on the manifold and head also need to be close to 5/16 ID. This will provide plenty of cooling. I like to tee a...

I.don’t understand why you are worried about pilot jet size when your complaint is lack of full throttle performance. Are you able to tune the top screw at full speed?

8X or 40X, its too much leverage and it doesn't matter. The crisis begins shortly after the LAST buyer has made his purchase.

Stocks are still too expensive. Buy stocks when old Superjets are back to selling for $1500.

For SBN44s I would get the popoff near 25psi. Remember that twostrokes can run with very rich mixtures, they just lose power and sputter more. The low screw can be set perfectly out of the water, just close until rpm peaks and then open to slow it back down. Where it ends up is anyones guess...
