I have a pro boat impulse 26 that I took out the old motor and esc and put in a castle 4.5t 4600kv 2 pole brushless motor into it( It has the water cooling shroud around it and runs super cool) but the esc(castle sidewinder, no water cooling) thermals like 3 minutes into running. I have a 1.6 x 2.5 pro boat prop on it that was used on the stock brushed motor. What prop should I get for my esc to run and not thermal? but if it gets up to like 140-150 degress thats fine as long as it dosent go over 160 degrees. Do I have to maybe get a better esc?, but i prefer to keep using my sidewinder. Please help me out guys
