Last year, I purchased a Pontoon boat that has a Johnson 90hp outboard motor. Although it sits out of the water on a "lift" and I have properly treated the gas for the winter, but I want to make sure I've done any water "draining" that some of my friends keep asking me about. I see no plugs or ways to drain any water that is/might be in the lower housing and would appreciate any suggestions or help. The original owner is deceased and didn't get any kind of maintenance books. Your comments would be appreciated. THANKS. 
<br /><br />UPDATE: Thanks to all who responded. I contacted the manufacturer with the model number, year model and other basic information only to be told I needed to advise whether it was a 90 or 180 degree engine. Yea, right...like I'd know and the boat is 70 miles away. All I would like to have is a picture of the motor and the location of the areas that I should either grease or where to check the lower unit gear housing for contaimination. If someone has a schematic or drawing or whatever might help would be appreciated.
