For the last 10 years, my brother,Alan, has successfully raced his Stealth 598 Step V in the NZBMC series with a 4.3 v6 190 hp mercruiser.
Well, the time has come for Alan to put on the big boy pants, and swim out to the deep end!
He's dumped a 383 chevy crate engine into the engine bay!
He moves from D class, up to B class.
What a beast!

The first 628 Stealth,fresh out of the mould!
My 17 year old daughter, Lily, is racing this in the N Z boat marathon Commission series, in E class with a 135 hp motor.
Although this model is designed for big horsepower, 300+,it's really exiting what the boat is doing with the little 135 on it!
Our plan is to keep Lily in this boat, and step up through the classes over the next few years, D class 150 HP, C class 200 HP, B class 225 HP, And A class 300 HP +.
