			When I installed mine tabs, I had the same problem, but  after a few trips (like 10 maybe) it stopped I have to say I don't think I got it bled out very well, so the more you use them the air gets worked out. Has been 5 years now, and have never added a drop since.

			leaking seal on cylinder.... I bet that if you trim full down and hold for a few seconds you will see evidence of the leak..... rainbow sheen on water or oil spots in driveway I had a trim leak this past july which turned out to be a cracked trim hose from transom to drive which only leaked when pressure was built up from down trim or boat in reverse in water |

			I am telling you when my old Yamaha was doing that it was the cover coming lose on the piston, I had to keep tightening it, then the O ring on that same cover went, the oil was washed away in the water so you could never see the oil leaking. I found it by lifting the motor up and down in the water , the oil made a rainbow, I just kept looking till i found it.
