Re: Getting a boat ready for salt water?
In addition to running water though the motor and washing the hull, you need to spray the springs, hubs, and axle down on the trailer. Alot of people overlook this and I've experienced the results. Especially if this is the only time you plan to dip it in slat water- you wouldn't want a freshwater trailer rotting like all the salt water ones. If it is an outboard, you'll want to wash down ALL areas exposed to salt water.
I had an abused mariner outboard whose pivot steering bracket that runs paralel to the midsection decayed to almost nothing before it was replaced. Powerhead had to be pullled briefly. If that part had dissapeared, my motor would have been hanging on by the control cables. It was a great motor, clean, flushed every time, but no one ever paid attention to the harder to see exterior parts. I noticed only months later. Cover all your bases and have fun.
