Turning up the boost makes me think the motors are not going to last and the NXT trans might break we are planning trips to Keys and Bahamas and dont wont to have problems
Motors have 7.5:1 compression which is very, very low, more boost, as long as controled with the proper fuel, spark and air discharge temp out of the intercooler is actually very safe.

I am very happy with it.

I go to several runs a year and yes some people go by me also they break a lot of times and I wind up ahead of them at the end of the day.

I am just like the next guy I want to go faster, but this boat will cruse at 85 mph making
5 lb. of boost all day. I came from a Scarab 26 that was about wide open at that speed
My last boat 35 lighting was really taxing the motors to cruse 85 mph all day.

My concerns are as follows:

1.) How much re-freshing (bottom or top end) do you have to do when you turn them up

2.) Will the Trans/clutch handle it

3.) I do not want to go back to pulling motors in and out of a boat again

The hardest thing on the engines is RPM, not boost. So if you want to keep your engine close to stock hours, then you'll need bigger props if your going to constantly be running top speed. For most, they just occassionaly take it up and this has very little change on the life of the motor.

Trans and drive has proven to handle the power.

You do not need to pull the motors all the time, even in stock form, the first thing to go is going to be the valve train, followed by head gaskets, so you should rebuild these around 300-400 hours no matter what.

What kind of torque does the whipple 700 upgrade give you?
The 700 stage 2 gives you just over 800lbs of torque, but this can also be dialed in to whatever you want.

If you want less torque, we can take timing away at lower speeds. Torque is also dependent on how much throttle you give it so you can always give it less throttle. You only reach peak torque when your full throttle.

I think I had it told to me there were some tweaks and upgrades to the ECM program since I had mine done a year ago. Is this the case?
