10point Posted March 18, 2011 Report Share Posted March 18, 2011 I took my boat out last weekend and last night I found what looked like a puddle of grease about the size of a grapefruit along with a little water under my motor. It appears it came out of the bottom of the motor where the propeller meets the lower unit. The motor is a 2000 9.9 2 stroke Johnson. Plan was to go fishing tomorrow but now I am thinking I might need to take it to a marina. Any ideas? Link to comment Share on other sites More sharing options...
skeeter Posted March 18, 2011 Report Share Posted March 18, 2011 Did you check the lower end gear lube screws that hold the gear lube in? Then take them out and drain the gear lube out to see if there is water in the lower end. Link to comment Share on other sites More sharing options...

fishnsled Posted March 18, 2011 Report Share Posted March 18, 2011 (edited) Oil leaking through the exhaust from fogging it? It doesn't take much to get a puddle that size, especially if it's been sitting there for a few months. Water could just be some condensation from the winter months or a bit of water from the engine intake. Was the motor fogged and the lower unit oil changed before storage? Is it storage in a warm area or cold? What colour in the oil? Edited March 18, 2011 by fishnsled Link to comment Share on other sites More sharing options...

Now you get to see what you pollute the water with. Link to comment Share on other sites More sharing options...
10point Posted March 18, 2011 Author Report Share Posted March 18, 2011 (edited) Haven't fogged it and I think it just appeared after taking it out the other day. I haven't drained the oil to check for water yet but will tomorrow. The marina here told me a lot of times it can be fishing line and last time I was out I got hung up trolling and had to break the line so that could be it. I will take the prop off tomorrow and see if there is line in it that broke a seal. Boat is stored in my garage. Can get cold but I do have an insulated door. I am going to have to look at more closely tonight but I think it was like a tan color. Edited March 18, 2011 by 10point Link to comment Share on other sites More sharing options...

Big Cliff Posted March 18, 2011 Report Share Posted March 18, 2011 Check the lower unit very carefully, look for signs of a crack. A clean paper towell wiped over it will pick up any oil that might be on it. If you do find oil on the towell then you may have had water in the lower unit which froze and could have cracked the housing or if you are lucky just blew the seal. Either way the leak has to be located and repaired before you go anywhere with that motor. If it just blew the seal, consider yourself lucky and remember to drain and refil your lower unit every fall before you put the boat away for the winter.

Billy Bob Posted March 18, 2011 Report Share Posted March 18, 2011 What Cliff said....but what color is the Oil/Grease......if black it's from the exhaust and forget about it and go fishing....if it's clear like....Houston, we have a problem...

It's most likely residue from unburned oil that has drained out the exhaust through the hub in the prop. If it was a lower unit problem then it would be gear oil which has a unique smell and texture. I have the 1996 version of that motor and it drains the residue every year, even if you don't fog it.

bow slayer Posted March 18, 2011 Report Share Posted March 18, 2011 if it is a tan colour like you mentioned sounds like you have water in your lower unit that has got in from a damaged prop seal.change the oil and replace the seal. http://www.ehow.com/how_7674124_replace-boat-prop-seal.html Link to comment Share on other sites More sharing options...
Billy Bob Posted March 18, 2011 Report Share Posted March 18, 2011 It's best not to assume when your dealing with the lower unit...a pressure test of the lower unit will tell all.... Link to comment Share on other sites More sharing options...

I agree, If its black its just exhaust, an nothing to worry about. Same thing happened to me last season.... I ran a lot of Seafoam at the end of the season because I had heard such rae reveiws...not sure if it had anything to due with the increased exhaust oil runoff, but it had me worried as well. In the end it turned out to be nothing. But if its creamy lookings....you have a seal issue. Link to comment Share on other sites More sharing options...
10point Posted March 22, 2011 Author Report Share Posted March 22, 2011 It was creamy and I took it in this weekend. Getting the pressure test done. Link to comment Share on other sites More sharing options...
fishnsled Posted March 22, 2011 Report Share Posted March 22, 2011 It was creamy and I took it in this weekend. Getting the pressure test done. Best that you did that before you ran into some major issues on the water. Sounds like a seal but could be as simple as an O ring gasket for the fill, vent, level screws. Hope it's not to painful on the wallet. Link to comment Share on other sites More sharing options...
