Just started my engine after a couple of years of storage and noted a couple of leaks where the powerhead(?) mates to the drive unit in the rear(?). It does not leak with the engine not running and the hose attached and turned on, only when running. The engine is an early 80's version. I seem to remember it being refered to as a cross loop model? I have been searching deligently to find the maintenance manuals I purchased years ago to determine what seal has gone south. Could someone enlighten me in the mean time? Thanks in advance<br /><br />Paul
