This spring when I got the boat out of storage I noticed a small amout of oil under the engine. It was dirty oil so I thought it was from changing the oil before storage. Now, after running it a couple weekends, I have a small clean oil drip under the bell housing between the engine and transmission. Is this a main bearing leak? Has anyone else had any similar problems with the GT-40. I have a 2001 Ski Nautique with only 80 hours on it.
