It’s that time of year once more, and unfortunately, it’s time to keep your watercraft for the season. While it’s always a bit more enjoyable to pull out your boat than to put it away, correctly winterizing your Yamaha outboard engine prevents engine damage and will certainly assist in a smooth start to the beginning of following period.
While there are numerous points you can do before keeping your boat to get a get on next season– like changing your oil, altering your Yamaha fuel-water dividing filter, and possibly touching up some scrapes on your cowling cover– there are 6 very recommended steps.
Thoroughly flush your engine
Stabilize your fuel system
Fog your outboard engine
Change your spark plugs
Modification reduced system oil
Separate your battery
Flush Your Engine
Electric motor flusher
It is very important to extensively flush your engine to eliminate any kind of salt build-up if you are a saltwater boater, or general mud as well as gunk if you are a freshwater boater. Failure to eliminate this particles can cause or add to deterioration in the engine. If you’re a saltwater seafarer, salt crystals in the reduced device can create a large amount of damage.
If your outboard has a hose pipe adapter, merely screw the tube into the port, activate the water and also let the water compete concerning 5 minutes.
Next, remove the cowling cover as well as try to find any salt or grime accumulation that might have cleared up outside any engine elements. If you spot any build-up, simply wash it away.
Lastly, turn the engine completely up, after that cut all of it of the way down to make sure every decline of water drains from the engine.
** Caution **.
Do not run the engine when purging while utilizing a pipe port. This approach is solely made for purging while your engine is totally off.
Flushing Your Outboard with the Engine Operating.
To flush your Yamaha outboard with the engine operating, you will make use of an electric motor flusher (additionally referred to as earmuffs). Screw your garden pipe onto the electric motor flusher, then move the electric motor flusher over the engine’s water consumption. You need to make certain that the earmuffs are entirely covering the water intakes. Using this flushing method, you will certainly activate the engine. But first, make certain that you have an excellent supply of water and that water is appearing on both sides of the earmuffs.
Beginning the engine and also make sure that water is moving from the tell tale. Assure that your engine is not overheating by holding your hand under the tell tale water stream. prop for 40 hp mercury outboard should not be awkward to hold your hand in the stream of water. If the water is exceedingly warm, water is not streaming properly, and you are overheating your engine– turn off the engine, rearrange the earmuffs, as well as start once again.
Maintain Your Fuel System.
Fuel stabilizer ideal for long term storage space.

Yard hose pipe.
Due to the fact that it is so usual, a number of us use ethanol-enriched gasoline much of the moment. We suggest making use of a gas stabilizer every one of the moment when running ethanol-enriched gas. Review our Ethanol Fuel In Outboard Engines write-up to learn why. Furthermore, it is important to use a gas stabilizer like Yamaha Fuel Stabilizer as well as Conditioner Plus when your boat will be sitting unused for anymore than 2 or three months.
Include the amount of gas stabilizer routed on the item’s packaging to your fuel– for example, 1 ounce of Yamaha Gas Stabilizer as well as Conditioner And also for each gallon of gas, assuming the engine will certainly be kept for greater than 2 months. If you are saving the engine for 2 months or less, the suggested ratio from Yamaha is 1 ounce of stabilizer for every single 3 gallons of gas.
Run the engine with stabilized gas for 10-15 minutes to extensively flow the stabilized fuel throughout your gas system. If your watercraft runs out the water, comply with the Flush Your Outboard with the Engine Running procedures outlined above.
Misting Your Engine.
Substitute spark plugs.
So, what is fogging oil or fogging fluid anyway? Yamalube fogging oil is a wax-based oil that coats the engine and protects against corrosion. As you resolve this process, you will quickly comprehend why this process is called fogging the engine as there will be plenty of white smoke.
Given that mercury outboard propellers will certainly not remain in the water while executing this job, you will certainly require to make use of a motor flusher to maintain the engine cool while you finish the fogging procedure. Adhere to the Flush Your Outboard with the Engine Running procedures detailed above.
If relevant, remove your engine’s air cleaner to reach the carburetors or cyndrical tube air intakes.
Rev the engine to a little bit over idle, and with the engine operating, spray the fogging oil into the carburetor( s) or air consumption of each cylinder.
Continuously spray fogging oil right into your engine’s carburetors or cylinder air intakes up until the engine delays. Be sure to spray a finishing of misting oil into each cylinder or carburetor. Do not spray too much oil simultaneously and also eliminate the engine right away, yet after a continuous spray, the engine will eventually stall. This is precisely what you desire, and the ultimate delaying indicates that the engine is extensively covered with fogging oil.
Next off, use your crescent wrench to remove the spark plugs as well as spray fogging oil into each cylinder. Turn the flywheel to relocate the cylinders permitting you to layer the whole cyndrical tube wall surface. As opposed to transforming the flywheel to relocate the cylinders, you can also simply start the engine for just a few secs to enable the fogging oil to coat the cylinder walls– repeat this procedure a number of times completely step. Replace old spark plugs with brand-new spark plugs to ensure that you prepare to enter the springtime.
Modification Lower Unit Oil.
Enough amount of reduced unit oil/ gear lube oil.
Equipment lube/oil pump (for obtaining oil back into the lower unit).
2 brand-new drain screw gaskets.
Drain pipes pan.
Large level head screwdriver.
A few cloths.
We strongly recommend altering your Yamaha gear lube prior to storage to ensure that there is no water in the lower device’s oil. Any kind of water in the oil can ice up, expand, and also crack your reduced device. Additionally, altering lower device oil means one much less point to do at the start of following period.
First, you’ll require to recognize how much reduced system oil/ gear lube you need to have on hand. Check your proprietor’s handbook or find your engine design within our Yamaha Specifications & Capacities Chart.
Locate the lower and upper lower unit oil drainpipe openings. With your drain pan in position, initially, remove the reduced drainpipe screw. The oil will begin to drip out right into the drainpipe pan.
Next, get rid of the upper drainpipe screw– oil will drain pipes out swiftly. Enable the oil to drain pipes entirely.
It is vital that you pay close attention to your reduced device’s oil. If the oil is a milky color, there is water in the lower device, and you will have significant problems down the road. If this is the case, go directly to your aquatic auto mechanic to diagnose the problem as well as ideally repair the issue prior to it causes a lot more damage.
With the oil entirely drained pipes, screw in your pump fitting as well as connect the pump. Eliminate
6E5-45945-01-00 of your container of lower device oil as well as screw the pump onto the bottle.
Pump till oil starts spurting of the upper drain hole.
Mount a brand-new lower system drainpipe gasket onto your top screw plug. Put the top screw plug, hand tighten, after that tighten firmly with your flathead screwdriver.
Install a brand-new lower system drain gasket on your reduced screw. With the lower screw in your hand, remove the gear oil pump installation. Rapidly insert as well as tighten the lower screw.
Wipe whatever down as well as appropriately throw away your old oil reduced unit oil.
** Care **.
There have to be no water in your lower system oil. If there is water in the reduced device oil as well as your watercraft is saved in the cool, the water in the oil will ice up as well as break your reduced system, which is most definitely a bad thing.
Separate Your Battery.
Battery terminal cleaner and also protector.
Detach your battery and spray Yamaha Battery Terminal Protector & Cleaner on your battery terminals.
