Yamaha Outboard Service Kits FAQ

How do you grease a Yamaha outboard engine?

Greasing your Yamaha outboard is an important part of keeping the motor functioning. A grease gun is an important part of maintaining your Yamaha outboard motor. To do this, you load a tube into the grease gun and use a trigger-activated plunger to slowly dispense the grease as needed into the grease points.

Grease points are metal fittings attached to your outboard motor that allow grease to be fed into the system under moderate to heavy pressure. Because you don’t have to remove most engine components to access the grease points, they’re easy to work with. To find grease points on your outboard, refer to your service manual for your particular Yamaha model outboard and add grease where grease “A” is specified.

How do you perform a Yamaha outboard leak-down test?

An outboard leak down test is a simple diagnostic checkup for your Yamaha outboard – and it can even be incorporated into your regular maintenance intervals for peace of mind.

A Yamaha outboard leak down test indicates the condition of each of the Yamaha engine’s cylinders and the overall condition of the motor. Similar to a compression test, it involves spraying compressed air into each cylinder and using a pressure gauge to measure a percentage of pressure that’s lost as compressed air after a short period.

Part of performing a leak down test on a your Yamaha outboard motor is to listen for any signs of leakage. By listening closely to each cylinder and the areas around them, you’ll better understand where leaks may be present.
