I was wondering if there is anything I need to do as far as maintainence on my new 2005 Mercury 50h EFI four stroke engine? I went through the break in procedure as stated, I add oil as needed, it "pees' water" good (as described by the dealer!!), but the only thing I have read is to bring it in for service at 100 hours or after the first year. It has not set up this winter; I have been taking it out fishing at least once a week. It runs great, no problems, but they all run great right before the BLOW UP!! LOL!!!
