Many Yamaha outboard motor owners live in climates where they are taken out of service for the winter months, which means winterizing their outboards is a must. … It ensures safe boating in the spring, and also helps to keep your outboard(s) performing well.
How do you winterize a Yamaha outboard motor?
Change the engine oil and filter by removing the 7/16th-inch crankcase bolt on the starboard side of the leg and letting the oil drain into a pan. Replace the oil and secure the crankcase bolt back into place. Start the engine/motor. Run it for about 15 minutes to increase the temperature to normal operating level.
Do outboard motors need to be winterized?
Like inboards and sterndrives, outboard engines are also subject to potential damage from freezing and from being laid up in disuse for months at a time. So outboards demand winterizing too. This project is simple enough to do yourself with the right tools, products and a bit of education.
At what temperature do I need to winterize my boat?
If you plan to use your boat year-round, and you live in a place where the temperature dips below freezing occasionally, you should winterize systems such as the water holding tank, showers, livewells, faucets and the head system — if your boat has them — and don’t use them during winter.
Should I Fog my 4 stroke outboard?
4 strokes do not need “fogging” because pretty much all the moving parts are already coated with crankcase oil. In fact,fogging a 4 stroke does not even reach or have any effect on 99% of the moving parts in a 4 stroke.
Is fogging a boat motor necessary?
Fogging oil is an anticorrosive that will protect the internal surfaces of the carburetor and the cylinders. Typically the engine will run rough just before it runs out of fuel. As that happens, give the carburetor(s) a heavier shot of fogging oil to make sure internal surfaces are fully coated.
What happens if you don’t winterize your outboard motor?
If You Don’t Winterize Your Boat, Here’s What Happens. Water freezes and expands and can damage anything it’s trapped inside. Water may seep into unprotected spaces to do this. … Mold and mildew take root, and you may come back to a boat in the spring that you can not use because of multiple system failures.
How do you keep an outboard motor from freezing?
Winter Outboard Freeze Protection
- Trim motor all the way down and let sit for a few seconds (you’ll see water draining from the motor).
- When the draining slows trim the motor all the way up again.
- Trim the motor all the way down again and drain any remaining water.
- Stow motor as usual.
Should I leave my outboard motor up or down?
When you park the boat for the winter keep the motor trimmed or tilted down, especially if it’s outdoors. This will allow all of the water to drain out of the motor’s cooling system. If it’s tilted up, some water may remain in the motor, where it can freeze and cause a cracked block or a ruined water pump housing.
Do I need to winterize my boat if I keep it in the garage?
Of course, as BOATUS states, the best winter storage space for your boat is “indoors, in a climate‑controlled facility with a backup generator.” This means that you need control over the temperature in your garage. A good garage door that seals out the cold will help keep your boat safe over the winter.
How cold does it have to get to damage a boat engine?
32 degrees is the freezing point of water. Water expands as it freezes and that is what can cause damage to an engine block.
What happens if you don’t winterize your jet ski?
Not winterizing a ski doesn’t mean you are going to damage the motor…it just means you are taking your risk from 0% chance and bumping it up to probably a 50+% chance of damaging it. It all depends on how much water is in there, and how it freezes.
Which is better 2 stroke or 4 stroke outboard motor?
Additionally, two-stroke engines are less fuel-efficient, get fewer miles per gallon and produce more emissions than four-stroke outboard motors. Four-Stroke Outboard Motors: A four-stroke engine works by running one compression stroke followed by an exhaust stroke. Each stroke is followed quickly by a return stroke.
Is it OK to run a four stroke outboard full throttle?
As long as you are propped correctly and can hit the upper end of the RPM range, [to run an engine at its maximum throttle all the time] is not a problem. Most smaller engines have two speeds, OFF and WOT. Very rarely does an engine wear out. Keep up with maintenance and you will be fine.
Do I need to winterize my Mercury 4 stroke outboard?
Winterizing is Really Important
Correctly preparing your outboard motor for the off-season will help insure that it’s ready to go next spring. In cold climates, freezing weather can cause costly damage to an engine that isn’t winterized properly.
