    It is not common for the tanks to leak. Sometimes it is from cross-threading or tightening the cap too much and a hairline crack develops between the tank threads. Other times it is the cap that is faulty.  Inspect the tank threads closely. If all looks good, try a new cap first.

    Late reply but I've dealt with the same problem on my 50 for quite a while. I hadn't even touched the cap in months because the oil lasts so long but one day after trimming it all the way up and driving home my bilge was oily and I was like ****? Did you ever get it fixed?
