kicker

[pikfish]

The HP needed for a kicker depends on what you want to do. Almost any small outboard 5hp+ will get you to about 8 miles an hour in calm water and even a 25 hp won't get you more than 9 mph. This is due to the limits of the displacement hull speed of a 20.5' boat (not on plane). The differance is if you need to fight a head wind and waves? Still you won't go faster but with more thrust you will be able to over come the resistance of the wind and waves. I totally agree you want an EX-long (20")+ kicker. What height is the current bracket mounted at in relation to the hull bottom?
