    Littlescreamers 63mmwater jacketed Motor

    Steven had asked me to post a little something about our new water jacketed outrunners we are producing. This is a project I have been working on for some time now and am very excited to be able to show off what we have coming out soon. I am posting some pictures as it is way simpler to show you how it work then to explain it.

    I will give it a shot!

    The internal cooling works by passing cold water through a bell attached at the end of the motor, This bell is removable and is sealed with 2 O-rings one front and one rear. this bell is completely enclosed and sealed, No water can enter the motor or the shaft as the bearing on the end is outside the bell and sealed with the O-ring. (see pic) Inside this bell is an extension of the bearing tube witch also holds the stator, Now on this extension I have machined cooling fins to absorb the heat with the water passing over these colling fins and the whole things is Aluminum so it wil act like a heat sink. So with this setup there will be no issues with heat and as all of it will be pulled strait from the motor and out the exit! The faster you go the better the cooling.

    As of now we are going to release 3 versions of this design

    1 for the Mini boats

    1 for the mid size boats

    And a competition 1/8th 1/10th scale motor


    Here is a picture of the new production 63mm water jacketed motor for 1/8th and 1/10th

        That is NICE! I just read a post where they are having great success with the outrunner's in the large hulls. Water cooling them is even better, might possibly make inrunners a thing of the past in a few years.

          The ones being used up here in the Seattle Area in the bigger boatsd I don't think they are even watercooling them. They don't seem to get hot at all

              There are a lot of people especially in Seattle that don't run to break speed records and run spec setups

                    Ok
                    I have a little more info on the motor.

                    This Large Water Jacketed Outrunner was designed for big boats 40-90". It will perform well as a drop in HP replacement for the Weed Eater type gas boats. Designed as a racing motor to run against the gas and will be competing in the racing scene beginning 2010. Testing so far in a 40+ Race hydro we are running 65-68 MPH and completing 7+ laps on 10s. This is very exciting for a low cost alternative motor to be running with the $600 Modified gas motors and the Large Neu inrunners. Testing continues and I will update soon!

                    These pictures are from the 55" Deep Vee I am doing a conversion on. I started with a new hull (Snagged from the LHS for $50 new in the box) and then bought all new Proboat hardware, I am waiting on an ESC and then I will finish this project. I am very excited to see this thing scream across the lake with the new power system.

                            Scott, any release info on a 4S, 1800 - 2200 KV motor ? I'm sure there's a big audience for something to compete with the Neu 1515 / 1521 types.

                              Working on that one now, I have 5 new motor designs going to the factory. 2 are smaller versions of this motor.
                              I will keep you all updated on how things are coming along.
