Lay-Up and Recommissioning
Many owners rely on their boatyards to prepare their craft, including engines and generators, for lay-up during
the off-season or for long periods of inactivity. Others prefer to accomplish lay-up preparation themselves.
The following procedures allow you to perform your own lay-up and recommissioning, or you may use them
as a checklist if others do the procedures. These procedures should afford your engine protection during a lay-
up and help familiarize you with the maintenance needs of your engine.
If you have any questions regarding lay-up procedures, call your local servicing dealer for assistance.
8.1
Lay-Up Prep: Lubrication System
1.
Warm up the engine.
2.
Drain all the engine oil from the oil sump.
3.
Remove and replace the oil filter and fill the sump with new oil. Use the correct grade of oil.
4.
Run the engine. Check for proper oil pressure. Verify that there are no leaks.
CAUTION: Do not leave the old engine oil in the sump over the lay-up period. Lubricating oil and combustion deposits
combine to produce harmful chemicals which can reduce the life of your engine and its internal parts.
8.2
Lay-Up Prep: Batteries
If batteries are to be left on board during the lay-up period, make sure that they are fully charged, and will
remain that way, to prevent them from freezing. If there is any doubt that the batteries will not remain fully
charged, or that they will be subjected to severe environmental conditions, remove the batteries and store
them in a warmer, more compatible environment.
8.3
Lay-Up Prep: Cylinder Lubrication
After engine shutdown, remove the spark plugs and spray a small amount of fogging oil into each cylinder.
Rotate the crankshaft manually two complete revolutions. Re-install the spark plugs loosely for winter lay-up.
NOTE: At spring commissioning, remove the plugs and rotate the crankshaft two full revolutions. Re-install the spark
plugs, tighten each properly and connect the high tension leads fully onto each spark plug.
8.4
Lay-Up Prep: Fuel System
Top off your fuel tanks with unleaded gasoline with an octane rating of 89 or higher. A fuel conditioner such as
Sta-Bil gasoline stabilizer should be added. Change the element in your gasoline/water separator and clean
the metal bowl. Re-install and make certain there are no leaks. Clean up any spilled fuel.
CAUTION: Gasoline with ethanol content higher than 10% (E-10) such as E-15 is not allowed and may void your
warranty.
8.5
Lay-Up Prep: Starter Motor
Lubrication and cleaning of the starter drive pinion is advisable, if access to the starter permits its easy removal.
Make sure the battery connections are shut off before attempting to remove the starter. Take care in properly
replacing any electrical connections removed from the starter.
