Ski Jet was actually two classes back in the 70-early 80's. I raced in Ski-Jet II which was a 460 CU limited class where you could run angle valve heads (BBC and Hemi) Ski-Jet I was for wedge head motors Olds was the primary motor. All iron blocks single 750 carb, and marine exhaust (over the transom was typical). No headers,
two seats, off center steering, through the deck fueling, no adjustable nozzles. Classes were run in drags and circles. we also had powder-puff heats for the ladies.

Than wizard

I saw some new rules on Njba website but wondered if anyone raced it was planning on doing it or heard of it

I gotta read the rules again but looked like limited CI motor adj nozzle was okay but I'd have to peek at it again

Im interested in a class which has fairly stock ski boat class u know very mild race class maybe that is the nestalgia class I don't know I'm in Norcal all the good stuff is in Socal as far as boat racing goes.

Okay so its a jet boat equiped with at least two seats or bench for two people
460 Max CI
Equipped with ski tow
Any nozzle
Any Carb non modified intake any production is fine
GPS speed up to 80
No aluminum blocks


Sounds perfect for a budget racer.

The current version of NJBA Ski Jet is an all out, hardcore racing class. Some of the boats can run in the high 8's. Not exactly a beginner's class.
NJBA does have several classes where you could start out:
River Racer - a non competitive class where you make runs and learn the ropes of the track and tuning your boat.
Super Eliminator - a dial-your-own-ET class where anyone can compete as long as they pass tech.
12.00 & up sec bracket - where you race against other boats that have similar performance.

When you go, let them know at sign up or drivers' meeting that you are new and people will help you learn.
Good luck.
