Hey there all, im an Aussie new to the Jet Boat scene. Been following and learning about Jetboats, and Jetdrives for the last year.
I was recently lucky enough to snap up a 500hp 79 Bahner with 454BBC, and Berkeley 12JC pump that was recently imported into Australia. Its a great boat, wicked fast and i love it! Its great to jump on Youtube and the forums to see some of the extreme Jet boats that you guys over in the states build!
My Berkeley pump has been recently reconditioned, but im already planning some upgrades. It already has a loader scoop but parts i am looking at include:
- Inducer impeller and suitable matching shaft. (Get a better hole shot)
- A/T Split Bowl with built in stuffer and matching A/T impeller.
- Berkeley style Droop snoot
- Hyd Place diverter.
Jetboats from the 70's 80's era are non existant over here! So i wanted to spruce the jet up, give the boat some more punch, and be able to throw a roost!
Problem i have at the moment, is while i cruise the boat has a porposing problem. The only way to help prevent it from occurring is to have the passengers sitting towards the nose as far as they can….. Or you have to perform a gradual turn to stop it bouncing, or just back right off the throttle.
At full noise it doesn’t do it, but at cruising speeds it does. Will the droop and place diverter help eliminate this problem?
Jim and Performance Jet believes that the droop could make the situation worse. So im not really sure what avenue to take. I really want the boat to not porpose, but still be able to throw a good roost. I understand every boat is different, i just need to discuss it with people from the USA because there isnt many people in the know over here.
Maybe i should keep the JC housing and Berk impeller, and just add the diverter? Roost wont be as big, but i dont want to make the porposing worse!
Also another thing, what is the purpose of a shoe/ride plate?
Any advice/ideas for the Jet boat owner in Australia?
