What is the differance in performance between the SCIC and the 4 Tec? I am trying to figure out if the 155 HP is enough. It sure sounds like a small amount of power.

I have a buddy running the 155hp naturally aspirated and he loves it...but, for the extra money the supercharged Intercooled motor simply out runs the 155 in every way...acceleration, mph etc. I have the Challenger 180 SCIC and wouldn't even consider the 185 hp SC w/o intercooler if that helps you any.

ExCon you talking about witch boat... the sportster and the sportster SC IC ?

The SC IC is a 4-tec... its the same engine then the 155 hp but there is a superchager and a intercooler added.

Based on the test, the Sportster SC IC accelerate from 0 to 30 mph in 3 second faster than the standart Sportster and the SC IC have a top speed of approximately 12-15 mph higher than the 155hp.

But the 155hp is enough power

There are all the Rotax engine with specification -->

if you can go for the scic - i did - and they are superb

i am getting over 60mph on mine with 2 people on board

deep water slalom starts for skiing are easy

it is a fantastic piece of kit.

plus in the future - a scic will have a better trade value or second hand value than the 4-tec, or at least thats what i think,.

Has any one installed a NOZ system in a 3I 155 hp Rotax motor.
Any one out there a mechanic, will it work?
How can you over rider the rev limiter or change it to a higer limit?

[thumper]

whats a noz system - is that liek an after market nozle rooster thing?

I think he's refering to NOS..or Nitrous Oxide. Adds a burst of O2 to the intake for a quick burst of hp. The Nitrous gas is stored in a 68 ci carbon fber tank.
