Marine Specialties 31 inch Challenger

Hi this was given to me.Just the hull,no box,or parts,or instructions.I run rc cars,planes,heli's,but never had a boat before.

I have been looking at boat parts to see what I might need at HK.Just a little unsure on what to get.

Hull is 31 inches long(780mm),9.5 inches wide(241mm),approx 4.5 inches at it deepest point in hull.

Any thoughts or help is much appreciated.

Thanks whiskykid,I've been searching google pics for days.

Any thoughts on the flex shaft?Maybe just get a 5mm one and see if it goes thru?

Fill the holes, pull out the stuffing tube (it's no good with the kinks) and set it up for a surface drive.
There are many choices for power depending on what you have or are willing to buy for batteries.
Thats a good hull, it deserves some decent hardware, if it were mine I'd be installing a speedmaster rudder and strut, 3/16 flex shaft (hughey makes the best) the prop would depend on the motor.
Everything you need to get it running with good hardware can be bought from the Offshore Electrics online store. Good guy to deal with.

Yep that would be an alright setup!
There is another way you could do it but is a little more difficult to implement.
It would use a strut as opposed to the stinger drive. The stuffing tube is built into a "wet well".
This gives you up and down adjustment as well as angle.
I've never built this particular boat so I'm not sure where you want to drill the stuffing tube hole in the back. I'll send you a message with a link

I have the holes filled,I guess I'll get it ready for paint while I wait on parts.I have a local hobby shop,that has a selection of parts,I need to spend at least an hour going thru the stuff though.

Registered at Offshore Electrics,and searched and found a few Challengers built over there,gives me an idea of was used.

I searched for a setup like you mentioned Sibe,"wet well",but cannnot find anything resembling it.Any pics or diagrams?

Thanks again.

Back to sanding..

It's kind of hard to explain.
If you can find pictures of the inside of a Proboat Impulse it has a wet well setup.
Basically you build a small sealed box around the last few inches of the stuffing tube inside the boat, there is a bigger hole drilled in the back of the boat where the stuffing tube comes out.
This allows you to raise and lower the strut a fair amount for getting the boat dialed in, the stuffing tube is able to move up and down giving you greater range of motion.
I have one done using brass tubing, give me a bit and I'll go downstairs and try to take some pictures of how it's done, This hull was bought set up this way used, I'm seriously thinking about re doing the setup, it works but looks messy. Got it stripped down trying to decide if I want to change motors, might be easier to buy another hull and keep this one running it's current motor.

The stuffing tube goes into and through the larger diameter brass tubing you can see on the inside.
The lager diameter is epoxied in with a pile of JB weld (messy part I don't like, used boat though)
In the second picture you can see the stuffing tube coming out the back of the boat through the large diameter hole.
The "wet well" is the fact that the large diameter brass can fill with water through the big hole, but it's sealed on the inside so no water gets into the inside of hull.
I can move the strut up and down a fair amount with this setup.
I prefer a sealed plywood box as opposed to the big brass hunk back there.

O.k. now I get it.Great pics btw.I see how you would have more adjustment.I don"t think I will have that much time in water to make it worth it.

I think I'll get that kit I linked earlier,I see they have the Hughey cables too.

This may end up being mostly shelf queen.

I'll change this to a build log,and keep updating.

Thanks for getting me the pics Sibe.
