Do you need to fog a Mercury 4 stroke outboard?
4 strokes do not need “fogging” because pretty much all the moving parts are already coated with crankcase oil.
Should 4 stroke outboards be fogged?
Fog the Engine Ideally while the motor is still warm, treat four-stroke and conventional two-stroke engines with fogging oil to prevent corrosion within the engine.
How do you store an outboard motor for the winter?
The best way is to either leave the motor on the boat or on an engine stand in an upright position, not tilted. If neither of these are an option, try to make sure that the engine is in an upright, self-draining position. If you can’t do this, be sure that the cooling system is drained completely.
What position should I store my outboard motor?
You want to leave the engine in the totally trimmed down position. This will allow all of the water to leak out of the engine, midsection, and lower unit. This will avoid freezing water and major problems!
How do you winterize a 4 stroke outboard motor?
Winterizing Your Outboard Motor
- Drain the crankcase oil (Four-stroke motors)
- Install a new oil filter (Four-stroke motors)
- Filling the crankcase with new oil (Four-stroke motors)
- Changing the lower unit gear oil.
- Stabilizing the fuel.
- Flushing the outboard with antifreeze.
- Fogging the cylinders.
How do you use fogging oil on a Mercury Optimax?
Use a fogging oil product that is specially designed for use during winterization, such as Mercury Storage Seal. For direct fuel injected (DFI) two-stroke engines such as Mercury OptiMax models, instead of using fogging oil, squirt one ounce of DFI outboard oil into each cylinder through the spark plug hole.
How do you use fogging oil on a 4 stroke engine?
Ideally while the motor is still warm, treat four-stroke and conventional two-stroke engines with fogging oil to prevent corrosion within the engine. Remove the spark plugs and spray the fogging oil directly into each cylinder, following the directions on the can.
How do you winterize a 4-stroke outboard motor?
Follow this winterization process walkthrough for a 4-stroke outboard motor, and watch our video above for visual guidance. The first steps in the winterization process are just part of your outboard’s regular maintenance schedule: changing the lower unit and engine oils. Step 1. Drain and replace the oil in the lower unit.
Can you use automotive oil in a Mercury outboard?
Never use automotive oil in a marine engine! Check your owner’s manual or ask your Mercury dealer for the recommended lubricant products for your marine engine. The dealer will also stock the Mercury Oil Change Kit for many Mercury outboards. Each kit includes oil, an oil filter and a drain plug seal in a convenient box.
