I need a 12V DC motor that can be ran fully submerged under water up to 3 meters. Horsepower range from. 5-1 with around 1500rpm and as much torque as possible. I will need a couple samples for protoying and the a small scale first order followed by more if all works as planned. This product will have a propeller mounted on it and be used to circulate water to keep ice from forming in small ponds. The shaft would need to be 3/8" or 1/2". Thank you for any help in this matter Show More
