Well, The proformance could be better, So far, the original motors seemed to do better, It seems that the boat cannot get off of plane, but it was doing that before I replaced the motors so I'm trying to figure out what it could be other than per haps the trip tabs. I've considered taking them off, or adjusting them, but I'm not sure which way I should adjust them. When I ran them, with a 5 coil water cooling kit over both motors, they seemed to keep a reasonable temperature, I didn't notice any overheating of any sort. Tomorrow I'm going to mess around with the boat until hopefully I can get it off of plane.
