I have heard that it is not good to let modern engines run dry though I don't know why. My 4hp 2s Mariner wouldn't start one year after storing it with gas in it. I finally got it cleaned out by spraying a lot of carb cleaner down it's throat. Now I run it dry every time I get off the water and have not had any more problems in the 16 years I have owned it. I also have a 50hp 4s Evinrude (not on the M15) that seems to always start no matter how long I leave it (no running dry with this one); I think the difference there is fuel injection vs a carb.

I was speaking with the service advisor about the right way to shut down a new Yamaha 4 stroke and he said don't run the carb, dry. He said just shut it off. He said the float inside the carb. should not run dry under normal boating. I also asked the same question to a different service advisor at the Suzuki shop and he gave the same advice. I was always told in the past to "run it dry" but apparently that's changed with the new tehnology motors., at least Suzuki and Yamaha. Anyone else discussed this with your outboard shop?
