RE: The new Sterlite Cat
I remember my first DIY boat, twin brushed motors, about 450 size, and 2 straight shafts to large 3 blade props. They where way to big for the motors. They where also coupled with wire insulation. It let go after about 3 minutes of plowing through the water.
The boat was a 1/4 3 ply plywood v-hull. I should see if I can find a picture.
You have a lot of room for improvement, but hey, thats what doing it yourself is all about right!
You water pickups will create a lot of drag, and if the boat ever gets some speed and climbs out of the water, they will come out of the water and you will loose cooling. (when it is most important) Try moving them to the transom and keep them vertical with angled tips. Only the back/stern side of the tube needs to be in the water. Any of the bow/front side of the tube will only create more drag. You may also get faster flow of water without the Tee fitting and 1 pickup. use the second for the motor.

RE: The new Sterlite Cat
Thanks man i was thinking that as well. Especially the angle pulls the middle of the boat down. After seeing the amount of water coming out while running i knew one would be enough. Going to attach it to the rudder and maybe find something with a triangular shaped mouth put the brass tube on piece of steel and tap it into a triangular shape. Man i cant wait to get some money together for a real boat tho my batteries are eating the dust bad. Took them out of some 18v nicd ryobi packs and they were already dead.
