We're on a river where you have to raise and lower the prop as you go from place to place, and that's easy enough with my little 4 HP Yammie. But as I look into larger jon boats that require more HP, I'm suddenly faced with the prospect of hoisting a back-breaker, and my back is "broken" enough already How do people with 15 HP and higher motors deal with that, if they don't have power trim?
