1. Use the full 4 digit year for everything you are asking your question about. Example: 1962, 1988, 2000, 2011
2. Include the correct name of your Whaler model. Example: Montauk 17, Montauk 170, Outrage 26, Outrage 260
3. Include the length when necessary. Example: 16, 17, 18, 20, 22

Tilt and trim O ring question

The tilt mechanism is still working but I am hoping I can get another month out of it before I pull the boat for the winter. Should I leave it alone, or is there anything (e.g a blob of grease) that I can buld up around the shaft to prevent water from seeping into the cylinder? The O-rings on the trim rams look fine. Any suggestions are much appreciated. Thanks. Peter
