   At the start of the season my boat would crank and run a few seconds and then shut down. Through trial and error and a little luck and help from this group I found that I was not getting emough air- If I unplegged the pcv hose it would run fine, but at too high an idle. I ran it around the lake with the pcv hose off and then it would idle fine when I hooked it back up.. It runs great as long as you don't idle too lpng. I have been trying to teach the grand kids to ski and that requires a lot of idling. after a short whi;e it will start to run badly and shut off when put ito gear. I think I smell gas. It feels like there is not enough air to get good combustion at idle, that gas is loading up on the plugs. If I run it around the lake pretty hard it will act right again- for a little while. I did the obvious- changed the pdv valve and washed out the spark arrestor. Any words of wisdom will be appreciated!

	Hi Don, I'd first check your spark plugs after it shuts down to see if there is indeed excess, unburned fuel (wet tips). If so this could either be a sign of failing plugs or worse, failing fuel injectors. When the injectors start to go bad they will sometimes drip during or after running. This can cause a hard start condition as well.
