Hi I am a newbie to the forum and electric boats, need all the help I can get. My Fireboat is my own design mono deep V hull built with plywood without plans and it is 55 inches long 16 inches wide and weight is 25 lbs without any hardware. The end weight will probably about 30 lbs with all batteries motor and other parts needed. The speed I am looking for would be 15 to 18 mph, the prop I think will do is an octura X450/3. I used the Octura brushless speed prediction -RC boat calculator but it does not take the weight of the boat into the factor. What I would like to know is the seize of motor ,batteries and esc that is needed without over heating anything. Thank you for any help.
