Pro Boat Formula Fastech Jet Drive Project

[Diegoboy]

I am considering scraping the Mamba project. It's too nice a boat and I'm to poor a driver. If she sits on the shelf long enough for my driving skills to improve, then...
I'd hate to wreck this boat, I honestly feel that the Mamba is too good a boat for me to run right now. I know, it sounds like an excuse, or even a cop-out, but it is the truth. I can't drive a boat. Why does the FEMBOT club only have 1 boat in the water at a time? Because I have been known to hit other boats.

This is going to be TOO COOL!

How is the hull quality??? I'm seriously considering getting one of these and seeing how it races!

This hull is surprisingly well built. The transom looks to be about 1/2 thick! *Correction 3/8"
Here's an inside view of the transom...

I Was thinking of buying the parts and building a hull skinned in thin alum. for bashing up all these small creeks and rivers we have here. maybe even set up gates to get through........a whole new venue for scale racing

I already started this one before I realized, I need to take pics.

On 10/02/2008 @ 7:16AM I made my choice

Thanks for those bottom pictures.
I have now found my next "jet" boat hull!
I'm excited about this one!

On 10/23/2008 the jet drive arrived, so the project begins.

Start with either a bare Fastech hull (like I did)



...or strip down a Fastech to it's bare hull.



Pull out the stuffing tube:
Remove the hatch, place the hull upside down and score a line around the stuffing tube base where it exit's the bottom of the hull. Score a line in the same manner to the stuffing tube where it enters the hull as well. Apply heat with a torch (keeping the flame directed away from the hull) and heat the stuffing tube from the outside. Once it's nice and hot, grab a set of pliers, channel locks, vice grips, etc. and twist the tube. you will hear pops, that will be ok. Do not twist degrees yet!
Keep this technique going until the tube lets go. Start twisting the tube 180 degrees now and get it out carefully.

Assemble the jet drive you have chosen. I choose the Graupner 40mm
