Lake Shannon water level down, fall winterizing reminders.


Dock & lift out, blow out sprinkler lines, drain hoses, turn off o/s spigots, clean gutters.

  • The inboard
    • Covered in detail on this post:
    • In spring: disable fuel/ignition before attempting to start engine. This will allow the oil to prime as indicated by the manufacturer.
    • Synthetic only.. why??? Shear strength .. helps if over heat… Valvoline vr1 or Mobil 1 15w50.. throw in some hyperlube zinc replacement. Motorcraft ok, but I like WIX or Napa platinum..
  • The outboard:
    • pull prop, grease
    • add stabilizer to fuel, run till stall
    • fog cyl’s
    • pull/ charge batt
    • change oil/ filter
    • add lube to lower unit ?
    • tilt down to drain, then tilt up
  • The PWC:
    • fill oil tank to prevent condensate
    • antifreeze the lines – pull, fill, turn over engine, pull refill
    • add gas stabilizer to fuel, then run engine w/ gas off until stall
    • fog cyl’s
    • pull battery, give a pre-winter charge before storing.
    • tilt to prevent water freezing in foot trays


Marine fuel: E0, E10, E85?

Running E-‘anything’?, update those lines and primer bulbs to ethanol compatible. Lines like to break down and clog your system. (I also like to add an extra glass fuel filter between bulb & engine on the outboard.) Note: wave runners are inboards and you do not want to compromise of any fuel line fitments and connectors!!

If possible, store your boat with a full fuel tank….in winter, add a fuel stabilizer the Lake Shannon Fenton MI Anibal Group LLCengine for 10 minutes to distribute stabilized fuel into the engine and fuel lines….top off the tank to reduce the amount of exchange with the air that may bring in condensation.

“…E10 may actually be a superior marine fuel, as it tends to keep low levels of water moving through the fuel system, keeping the system “dry”….However…”

E10 is certainly not as trouble-free as E0, especially the first few tankfulls. But for newer engines, those built after about 1991, there’s no reason the initial problems can’t be overcome. No less an authority than Mercury Marine says, “After the transition period from E0, E10 may actually be a superior marine fuel as it tends to keep low levels of water moving through the fuel system, keeping the system ‘dry.'”
