www.hyperprod.com has the Rossi's. I've got one and it runs very well but they take what seems like forever to break them in.
I'm still lloking for a CMB dealer.

The pull-start engine I don't know about, I didn't know that they had one!
The .21's have 3 names, Pirahna, Niagara and the Marinello (sp.). The spec's are all the same from what I've seen, just the color of the cases and heads are different. Mine is supposed to be the Niagara.

what are they just different models from each year , as you said with a diferent paint job . ha , alright thanks, hey alo i was looking at the rossisales and is that the best ahrdware to use , i have again looked around the web and most places that sell hardware kits are made for gas boat, and i have no luck with local hobby shops in my area , they carry no boating stuff and wont help you when it comes to ordering stuff, so most of my research has been done on the internet. any other hardware stores that you know of that you have used and would recommend would be great. clay

I just found a site with CMB's, http://www.seaducerboats.com/motor.htm . If Jerry Crowther has them, get the TT pipe to go with it. It'd very reasonably priced for a tuned pipe and very quiet. One friend has the engine and pipe and it's so quiet that you can hear the water splashing off the hull.
The Rossi pipe I didn't care for and the header placed the pipe too far out for me so I used an old Nova Rossi header that I had, the one in the shot hooked to an Irwin quiet pipe.

It's a Speedmaster 21.
I'm not sure who's selling the Irwin quiet pipes right now. Check www.rocketcityracing.com and look for the Cooper pipes, they're the same thing as he took over the inboard pipes from Jim Irwin.

It came with the boat. If you need a radio box, Aeromarine sells them in a lot of sizes and shapes.

Are you asking whether to buy a pre-made radio box or make your own? If you've got the tools, some plywood, and the time, they're easy enough to make. If not, just buy one.

When you make a box out of wood it's a good idea to waterproof it both inside and out. Epoxy works fine for this. Use slow curing epozy and a bit of heat to thin it.

when making the lid for a box do you use a fiberglass top with a set of hinges to make it able to get it to or do you seal the entire thing. thanks clay

I guess I'm too utilitarian. I can't see myself spending $40 for a 4 ounce tank! [X(]
