I was hoping to see this one on the forum, but did not. I am a new boater this year with a 14' 5" Scout boat.<br />So far I have left the plug out. I am glad that I have a float operated bilge pump. I also had read that the cockpit scuppers were "one-way". In reality they have a stainless steel cup that will not let water in if you are moving at a good clip going forward. I thought there was some sort of valve in there that was "one-way", Nope! Launching with the scupper plugs out just scoops up water. But it will drain the water out as soon as I was moving.<br /><br />My most embarrasing mistake was loading up the boat on the trailer and pulling up the ramp and hearing a loud scrape and bang. I stop, jump out to see I left the O/B in the down postition. Well I scratched up the skeg pretty good but other than that Things are OK.<br />I'm sure this has happened to others. the other day I saw an I/O on a trailer with a skeg that looked like a question mark. I'm sure the lower unit on any O/B has got to be expensive.<br />It is also a good idea to bring your fishing rods, if you are planning on fishing!
