Yamaha 100 Oil leak

New user and looking for advice on Yamaha 100 4 Stroke. Engine is 2000 with about 1100 hours but in mint condition.
Recently Iíve noticed when I return to the boat that thereís oil dripping from the lower front cowl down the transom into bilge sump. I store the engine tilted.
Under the hood thereís no trace of oil dripping or leaking anywhere . Tried the usual spots, filter, dip stick fill point etc but nothing other than this small amount that gathers at the front of lower cowl when tilted and drips out. Any ideas ?? I did notice oil level on dipstick is at max but that shouldnít cause it ?
Please help.

hi I had the exact same problem with a yam 80 similar hours looked every where for it and couldn't find it. I took it in to cammy at clyde outboards in Greenock for a service and he got it straight away it was a bolt that had worked loose underneath the bottom tray not shure which one but he cured the problem.
