    3.9 HP model year and value

    I'm thinking about buying a 3.9 HP outboard from a local guy. The serial number is 2444631 and I was wondering that year that may be. One chart I found would suggest 1967, but another suggests 1968 or later. The guy selling it thought it was 1978, but I don't show them making this HP that...

    Honey colored oil out exhaust port on 59 10 HP Johnson

    I went fishing in a no wake zone, so the day was limited to trolling. The next morning, I noticed a sizeable puddle of honey colored fluid on the floor of my garage. It was coming from the exhaust port. I've used this engine a few times before without issue, but have never only trolled. I...
