I have a 96 5hp 4stroke kicker with water in the crankcase. I ran it last year with new oil in it in spring. Changed it October and the oil that came out looked fine. Used it up in LBN into November in cold temps and rough conditions. I took the kicker off before I stored the boat and was finally getting around to changing the oil and the lower unit and found the oil in the crankcase was milky. Could the cold air and water temps have something to do with it or did a gasket or seal let go? |

Jon,
The crankcase is vented, so atmosphere can get in. I would change the oil and keep an eye on it. If water was getting into the crankcase due to a bad gasket or seal, it seems to me you should have noticed water in the cylinders also.

In my area (Maine) a lot of guys are experiencing the same issues with the 4 strokes. What we found was that they a very cold blooded and take forever to warm up and if you use them regularly for short runs the thing never comes up to temp properly and has a tendendancy to build up condensation in the crankcase. If you start them up let them warm up properly and run them for an hour a day at least this does not seem to be a problem. Kim |

Kim and Jon,
I have worked on some four stroke outboards, but not many. The long warm-up time that Kim refers to makes sense to me. Four stroke engines, using carburettors, need to have the fuel warmed up before it gets into the cylinders in order to run well. There really isn't anything to facilitate this in an outboard. In my opinion these engines need fuel injection, especially in colder applications.
