love2speed 0 Report post Posted March 20, 2014 I changed the out-drive oil on my new to me Monterey 322 last fall and noticed that both out-drives are slowly leaking at the drain bolt.I can only think that the size of oring the marina gave me was wrong because when I put them onto the bolt they did not seem to sit in the channel very well, by that I mean they did not fill in the channel. Also the marina gave me 3 different orings for the drain, vent and dipstick, but my research suggests that the vent and drain are the same size??Any info/advise would be appreciated.Thanks in advance Share this post Link to post Share on other sites
