Hey Alex- Your set up looks pretty good. Here's a couple of ideas.


Looks like you have solved this already but- To hold the battery pack in place you can use some velcro patches. Place one near the edge closest to the motor and then attach some pieces to all your battery packs. I use the fuzzy side of the velcro on the battery packs and grabby part (technical term) in the board itself. The velcro not only holds the batttery pack but it also elevates it slightly above your u joint or motor coupler.

You can also fit 7 cells in there though you may have to cut away a little of the shrink wrap in the front of the battery pack to give clearance for your cen racing u joint. The 7th cell would be attached to your six cell pac cross ways at the end nearest the rear of the hull. This will also help balance the board so it doesn't bounce around as much.

Someone suggested making a bigger coil to keep the motor cooler and I totally agree. If you decide to add a water cooled speed controller you can add another water pick up made from brass to the other side of the hull. Make the exhaust hole on the right side of the hull. Basically opposite of the one that's there now. Your intake looked fine in the picture you posted. I would check and make sure it isn't plugged with anything. You should be able to blow air through it fairly easily. Another test is, get a mouth full of water and blow the water through the exhaust hole on the side. If your making a new one you can use bigger diameter brass tubing then the stock set up. Yes it will help if you angle the intake slightly forward. You can exit an 1/8 inch from the bottom of the hull without incurring any noticeable drag.

I saw your movie (nice music btw) and it looks like you getting some good speed. If you want to bump it up another notch you can try the Mega Motor 22/20/2 with a 70amp Hacker navy controller. This set up rocks on 7 cells.

I use marine grade grease in the stuffing box.

Here's a shamless plug......A friend and I actually produced a movie/DVD about RC Surfing called Radio Waves. It includes a bunch of modifications you can make as well as some pretty cool rc surfing footage. There's a review in the latest issue of Radio Controlled Boat Modeler (2006 Buyers guide) as well as the March issue of Surfer Magazine. There is also a teaser clip on my website just in case your interested in seeing what is possible with a modified rc surfer.
