Winterize!

For boaters to whom the coming of cold weather means a seasonal reduction or hiatus in the activities they love, there are few less happy words than "winterize." But conversely, there is no better way to protect an investment or assure a trouble-free return to the water when the calendar swings back toward sunshine.

The following checklists are adapted from the maintenance manuals of Nauset Marine on Cape Cod, a part of the world where summer boating conditions are widely regarded as idyllic, and in a bad winter the Bay can freeze all the way to the horizon.

All lists end with the admonition: LEAVE YOUR BOAT CLEAN!

  • Gear Oil: change; double check sealing washers & replace if necessary
  • Prop: r&r as needed; regrease shaft
  • Teleflex: pull out tilt tube and grease
  • Grease Fittings: grease

  • Cylinders: check balance; pull plug wires
  • Fuel tank: use fog-mix; don't run dry; add stabilizer; tape caps; fill (but do not overfill) built-ins; drain six-gallon tanks if less than half full; don't fuel rusty tanks; double check gauge when filling tanks
  • Fresh water systems: add antifreeze or drain
  • Salt water systems: drain
  • Overall: spray engine with lubricant
