115 or 150 e-tech?

[DoozleD]

I have a 1977 master angler with a 2002 yamaha 115 4-stroke...I hate the yamaha, its heavy and has no mid range, i think the boats slow, i cruse it a 4000 to 4300 and im getting 17kts. i feel like you have to put it in the corner to get faster cruseing. Its not the prop!...i guess my question is what are the quys that have 20's with e-techs running for power and what are u getting for numbers?..
