So I haven't had a boat since the 70s. Laugh all you want. I bought this little john boat with a 25hp Mercury Force motor. Its got a trolling motor and two batteries. Its on a single axle trailer, has leaf springs. No data plate on the trailer. The hubs have grease zerts in them. So I'm thinking my first steps are, replace all of the fuel lines and such, they look kinda dry rotted. I'll replace the fuel tank too. I don't know yet if the engine runs, i'll get to that. I want to take it out on a trolling motor only lake this week. I need to know, 1: will a standard car battery charger be acceptable to charge deep cycle batterys. 2. How do I check the wheel bearings to insure that they have been maintained? 3. How much and how often should I grease said bearings? There is no data plate on the trailer to indicate manufacturer or lineage. After I make sure that my woman and I arent too fat and sink this boat, I'll get to the motor part. I grew up on the Chesepeake. This is a different world from that.
