Well, I put an Octura 440 prop on my nitro, replaced the shaft, replaced the pick-up tube with a bigger brass one, replaced the receiver batteries with ni-cads,replaced the exhaust tube with one that wont melt, and replaced the glow plug wire with one that won't fall off, and now I have a fast, awesome boat!

There are new pictures of my boat and modifications at:
I bought the high temperature exhaust tube at Mark Twain Hobby. It is made
Blue Line Exhaust http://www.remotecontrolproducts.com/shop_exhauststacks.htm
It is the same exhaust tube used for tuned pipes on airplanes.
The part number is 1024. It has a 3/8" inside diameter
and a 5/8" outside diameter. The stock pipe is 1/16" thinner and seems
to melt easier.

You need an octura part # OCGCSS prop shaft and an Octura x440 prop
I also got these parts at Mark Twain, but you can easily order from Octura.

I did not change the tubing for the cooling also. Only the pick-up tube
seemed to have an unusually small inside diameter so I just replaced it.
I still pipe the cooling out the exhaust but am considering to vent it out
the side if I can find a clean way to do it.
Also, the extra stabilizing fin in the rear of the boat seems to be mounted
wrong and the boat actually performs better without the extra drag.

Hmm, I have one of the first Nitro Vee's that hit the market and I know there's been some changes since then, but can you explain how your cooling is run through your exhaust http://www.traxxas.com/ubb/confused.gif
Currently, I have one inlet hose (from the pickup) and one outlet hose leading out the rear (between the muffler tubes)...
Also, there's a hose leading from the bottom of the exhaust manifold to a fitting on the driveshaft tube...
What exactly is this for http://www.traxxas.com/ubb/confused.gif

Did the same thing to mine and now it's an even better boat. I ran the water discharge out the side (just made a small groove in the side of the cabin), cut the end at a 45 deg angle, and used brass (can use aluminum also)7/32" tubing. Also used a little larger sized silicon tubing in making the bypass. I left about 5/8" original water inlet tubing to the muffler, but pinched it off with a tie strap.

The Tube coming out of the bottom of your exhaust manifold over to the drive shaft allows the excess oil in your exhaust to lubricate the drive shaft. On the newer Nitro Vee, the exhaust manifold is in the path of the cooling tube leaving the head because Traxxas had a lot of trouble with the rubber exhaust tube melting at the manifold. The cooling tube on the newer boat goes into a fitting on the muffler so that the cooling water exits the muffler.
