You may have a boat, but it may not be performing how you want it to. Maybe it's not giving you enough power or the fuel economy is bad. You can improve these things when you repower the boat with an outboard motor. This is going to work out in your favor if you take these actions. Be Honest With Current Boat Performance The only way outboard motor repowering is going to lead to optimal boat performance is if you're honest about the way your boat currently performs.
