I just switched to all lithium batteries, this weekend fishing a tournament I could only get 60mph@5800 rpm. I was running 65-69 same load before the battery swap.
2012 nitro z9 with a 250 pro xs and 8inch hyd jack plate, 1 talon, 25 pitch tempest 3 blade. I can get an inch or 2 up on the jackplate and I start to loose speed. Trim is maxed and rooster is about as high as the motor. I am at 25ish psi water pressure.
I want to get this prop worked but I want to have my set up right before I do... Before I put the lithium in I was maxed on trim and almost at the bottom on the jackplate. The motor is mounted as low as possible.
I will try to measure prop to pad tomorrow, but in the meantime any suggestions?
