How come the kid in blue had no life jacket?

I knew someone would pick up on that. He had one on as we got on the boat, but decided he wanted a different one as we pulled out of the dock (literally seconds before this picture was taken). The women all pulled out their cameras before we had a chance to get the new one on.

To throw my two cents in. The post under handle of "southern7" the hyperlink put up, thanks. I hit it, and found a Force prop I've been looking for, and called them. The guy Gene there knows his sh** (stuff), and put up with me putting him through the 3rd degree. Then only charged me $12.00 for shipping!! and should it not fit (due to wrong info on my end) will take it back! I wish it was that easy evertime I need parts or dealing with someone. Thanks

We just bought a new 18' Sun Tracker Party barge. It came with a 13.75 X 13 and would do 24mph. It would over speed, so I replaced the 13 pitch with a 15 pitch stainless. Big mistake, the prop 'slipped' at anything over 4000rpm. Then tried a 13.75 X 17. Get about the same speed, but engine won't turn over 4200 rpm. Soooo, I guess a 17 pitch is too much, and a 13 a little too low. I'm having the 13 pitch redone to a 15, which should be just right. I should get another 400 to 600 rpm and a couple miles per hour. When I get the prop back from the prop Dr. I'll let ya know.
