Newbie new build delta force 26"

[Brushlessracev]

i do not know if anyone has tried this but i am going for it, I am using GM windshield washer pump in conjunction with a 5amp speed control and mixing it with throttle for cooling motor and speed control. in theory it should work really well, more speed more water flow or you can control water flow with throttle curve. if nothing else it will propel boat back to shore with water pressure. the water out lets will be sum urged in water at stand still.

well that sounds good in theroy but in reality the motor and esc run coolest wide open. the esc builds more heat at lower throtle than it does at full wide open. think of how it works, it is a switch; at lower throtle it is on,off,on,off,on,off,on,off,on,off,on,off, at full throtle it is on... plus you had better start watching the weight, this is a 26" mono on 8l 3s... it would be one thing if it was on a 1515 1y or 8xl but it is not.... good luck but i would reconsider that idea..

Its really not needed and will add extra weight to your boat with no real benefit.........although, i totally understand fabbing something different and neat.........i watercooled my motor on a land rig once

its only 5 oz of weight i do not see this being a problem

It's 5oz of dead weight that you can do without though. What type of pickup are you going to run on it? I bet the pump will cavitate like crazy depending on the pickup type and location.

i just weighed the pump and speed control and its only 1.8oz i really do not think the weight is going to be an issue. one 2s battery weighs more.

How will the pump pick up water when the boat is on plane? A single rudder pickup is plenty of water to cool the esc and motor. Too much flow is not good either.

twin rudders, i am not using steer-fins just trim tabs. we run a coarse so i want it to turn right just as good as left so twin rudder was a idea,

So, how will the pump stay primed while the boat is on plane? 2 rudder pickups? Certainly no need for a pump.

boat is only going to be on plain for just a few seconds, we run a coarse so at slower speeds the pump will be picking up water at plain the rudder will force water past the pump.

On plane for a few seconds? If it is moving, faster than 10 mph it will be on plane. The only time the pump will work, is at a stop.

ok!! rudder is in the water all the time or you would not be able to steer the boat.

So, why the pump? Will the boat be sitting stiil in the water for a large amount of time between throttle? All I am saying is that you will not need that little extra help from the pump when the boat is at a stop. Your rudder pickups are more than enough.

thanks for the help i will keep it in mind. i think its a good idea. i do not know why your trying to be so negative about the idea. when my motor is running at 60 deg your is at 100+ you will change your mind about the idea.

[Rumdog]

Not negative. Just questioning your motive. BTW, you are the self proclaimed newbie. I am just offering help, and trying to understand what you are wanting to do, and why.
