Can't wait to see your results! Looks like a very well thought out build. At that power level there is a lot of speed left to find with small tweaks to the ride plate and pump angle.So, I got a little crazy and I’m completing the last mod to finish up the stage 3 build, that I doing to my SX195.
Here’s a list of the mods that I have completed so far...
*Jet boat Pilot Lateral Thruster
*Wet Wolf Yam-5 Adjust a Thrust
*Solas Concord YV-CD-13/18 Impeller
*K&N Cold Air Intake
*Fizzle Factory Y-1000 Intercooler
*HKS SQV4 Blow off valve
*RIVA Racing MaptunerX Stage 3 Tune
*Worx High Flow Water Strainer
*Engine-Tech 17 PSI Boost Wheel
*Riva Racing 1000cc Fuel Injectors
*PLX Monitor with Bosch Wideband O2
*R&D O2 Sensor Housing
*AMSOIL 10w40 Marine Synthetic Oil
*Resonator Delete w/Custom KCS Free Flow Exhaust
Jesus at Riva racing was able to build a custom tune and we got everything dialed in before the end of last season. Currently it will do 60 mph @ 8550 rpm with a full tank of fuel, 3 adults, and gear.
The only upgrade I’m completing right now is to remove the jet pump and switch to a SOLAS Concord YV-CD-14/21 impeller. I am currently running a SOLAS Concord YV-CD-13/18. After speaking with the guys at Impros, I decided it was a good idea because the boat is making, so much more power than stock motor, With the higher pitched impeller of 14/21, it will lower the rpms to about 8350 at WOT, but will increase the top speed to about 63 mph, with a normal load.
I’ll let everyone know how it goes, once I’m done....
Based upon what I’ve seen so far in regard to adding power to these boats; is that eventually your drag limited by the design of the hull!!
I'm running 12 psi boost. On a hot day I'm running 60 mph @ 8350 rpm. On a cool day I'll be bumping the rev limit at 62 mph @ 8550 rpm. That's with a YV-CD 13/17.? Pitched by Dean's Team. I credit 2-3 mph to ride plate and pump angle adjustment. Not sure what the max safe speed of our hull is...
