  • Rub rail leaks??

    I have a 1994 maristar 200. The rub rail was removed and replaced (caulked all screws when replacing them) and I have removed the back seat and tank and sealed the entire inside, but still getting lots of water at 10-20 mph. Has anyone had a simiar problem and remedy?

    During my first few weeks with my '93 I noticed water POURING in the back right of the boat anytime I made a slow left turn. It was hard not to notice because the rear corner became saturated with water during these turns. All I did was seal the bottom lip of the rubrail where it met the fiberglass. I used some clear marine grade silicone and water never poured in again.

      Hey footin

      My boat leaked like that - I used polysulphide black caulk (BoatLife) anf just ran a bead up under the rail - if you use masking tape, you'll get a nice straight bead that won't need much tooling (with your finger) boat's rail is black with a black stripe just under it so the "repair" just disappears...

      Due to the config. of the hull back there, get someone to drive at 20 mph +/- and if you stand back there and look you'll see water being kicked right up under the rail and consequently, forced thru the crack...

            Hey Wes - did you ever get your motor straightened out?
            If one day you're asked:
            " How did you spend your time here on Earth?"
            Will you say:
            "I kept a crabgrass free lawn"
            It's time to SKI.

                Same leak in 2003 MS230

                Just tried the silicon fix under the right rear end. My neighbor with a MS 210 1999 had the same leak. Has the factory offered any guidance? Seems like this is a very common problem.

                  I am getting more and more water in the center bilge compartment?
                  1999 Maristar 210.
                  Heater system is by-passed. (We never use it.)
                  Motor bilge is dry.
                  I don't get it?
                  Prop seal?

                    Check your packing on the drive shaft
                    Lots of power is good, more is better, too much is just right.
