    I should be able to get you the wiring diagrams for your boat.  I am sending you a Personal Message regarding it.  Look for a red number "1" next to the globe and envelope icons next to your Avatar in the upper left corner of the screen.  Click on the envelope, then click on my message to read it.

    There is a tube going out the back under the motor area that has a red handled lever that has always been horizontal to the bottom of the boat. does anyone know what the lever is for? When trailered and lever is switched to vertical it drains the area under back quicker. Should it remain in the horizontal position.
