Kicker Horsepower

[Geekie1]

I didn't want to highjack the "Auxilliary Motor" thread so I started this new one.

I have a V20 cuddy with a 150 Yamaha and with gas prices as they are and how prices may get I am seriously considering installing a kicker. I go offshore alot and do some trolling from time to time depending on conditions. Sometimes I troll out about 10 miles to a spot where I anchor to do some striper chunking. My V20 has outriggers etc.

I think that since I would use the kicker to troll which requires varying speed to match the bait presentation may require a larger kicker than a 10-15 HP. I want economy plus useful trolling speed. My question is:

What HP and leg length kicker would be most useful on a V20 for how I use the boat?? I will probably buy a Yammy for the kicker and just switch fuel hose from the 150 to the kicker when in use. Thanks in advance for your replies!!
