    How to tell if outboard is salt or freshwater

    Smoke in Carbs on shutoff

    Pontoon Replacement?

    I just bought a 1971 MonArk 24ft Pontoon boat w/ trailer and motor (for cheap) and started looking over all the things that I need/want to replace. The pontoons are in pretty rough shape. They do not appear to have been punctured but someone has obviously hit a few logs, stumps, and docks in the...
