I learned to waterski at 6 - I was a skinny kid - and it can't be done on a 10 horse. You need at least 25-35, 50+ is better.

"Navigable Waters" is basically anything you can navigate, even in a canoe. Got to license that 9.9 in Washington.

I have a Suzuki 9.9 4-stroke that will push my 15 foot Smokercraft along at 20-21 with me in it and 16-17 with a bud. I'm looking for a bit more motor, however, and may be interested in selling the 9.9 - it's 2 years old and has a 5 year warranty.

Carl, what kind of 15 footer are you running your Yamaha 15 on? I'm trying to decide if I want a 15 or a 25 - my bud has a 25 on his Gregor and it will also troll at nearly a standstill, while shoving it back up the drift at a good clip, but his boat is quite a bit heavier than mine.
