I have the captioned motor on my CL16. It runs great however whenever I put it in the water or start it I notice that a small amount of oil or gas has obviously gotten into the surrounding water. This is no good. One of the reasons I like sailing is that it is easier on the environment than motoring. I have three questions
1. Does anyone have any ideas on what might be going on?
2.I am running 50:1, is it possible that this could be 100:1 model?
3. I think I am going to have to stick a crowbar in my wallet and either buy a clymer or seloc service manual and/or the original owners manual. Any advice of which of these would be the most useful?

Hi Dougster. Couple of options come to mind. Could be residule fuel/oil mix from the exhaust. Your fuel/air mix could need adjusting. Two strokes are polluters. My old Merc does the same thing, and I'm told it's from the exhaust and I don't like it either!
Could also be a small leak in the seals of the bottom end.
You may be able to source a repair manual at the public library. The library in Barrie has shop manuals for most outboards, maybe your library has them too.
Some guys go for the zero pollution motors, ie. electic trolling motors.

I had the same problem with my fishing boat motor. The source was the prop shaft seal. As was said, all two stokes put out residue from their exhaust, but if it seams like it's getting worse check the seal. On my Johnson 50 it wasn't that hard to change.

Thanks, I think you may have diagnosed the problem. I left the motor on its side in the garage for a week or so and when I placed it back upright about an ounce of oil drizzled out of what I believe is the water intake. I have a fair amount of experience with 2 cycle motors however I haven't ventured into a lower unit before. Any advice?

I just tackled the lower unit on my Suzuki 5hp recently. Took it apart, checked the water pump, seals, changed the oil and had it back together within the hour. (Now that's not to say that it took me a few days to find somebody to tell me where the linkage rods disassembled so that I could pull the lower unit off), after that it was a piece of cake. On mine the linkage rods disassembled behind an access plate about half way down the leg. Others disengage under the engine cowling, and still others are under the motor but above the cowling. Ask specific questions at your marine dealer, and they will likely tell you.

If indeed you had oil come out the water intake, you may have had some water stay in there over the winter, freeze, expand and crack the casing. Only inspection will tell for sure. Good luck, and put a pan under your motor as you work to catch the oil that starts to come out at the unlikliest moment! Don't ask me how I learned this.

Another area that "may" leak oil is the lower drive unit drain hole. Some people forget to put on a new gasket seal when they put the screw back after changing the fluid.

Our old Merc 9.9 on the power boat had this problem. It's an easy fix.

Be thankful you don't have an inboard that you're trying to look at under the cockpit seat in a tight spot. They may look a bit ugly hung on the stearn but at least they're easy to work with on a bench.

Thanks for the help. I have taken a picture of where the oil seemed to be leaking from
