Yamaha Break-In
New Yamaha Outboard Break-In
New four-stroke boat motors have a lot of similarities to car engines ,however they do have a few differences as well. The biggest difference between a car and boat motor is the break-in process, as most cars are turn-key and ready to go.
Since boat engines are designed to run at constant RPMs and are put under intense loads, it is very important to properly break in your motor. It is a very simple process that anyone can really do and we recommend that everyone with a new boat follow this break-in procedure that Yamaha recommends.
The first hour you want to keep the boat under 2,000 RPMs. So really all you are doing is driving the boat around and keeping the motors under 2,000 RPMs for an hour.
After the first hour you bring the speed up and keep the boat under 3,000 RPMs. This speed will be just about on plane, and you DO NOT want to be full throttle.
For the next 8 hours of run time run the boat at varying speeds and avoid running the boat at wide open throttle for more than 5 minutes. After 10 hours run your boat at normal operational speed.
Once you have had your boat and have ran it for 20 hours ,it is time to bring your boat in for a service. This service ONLY happens at the first 20 hours and is designed to drain out all the fluids from the initial break-in, as many internal parts of the motor are moving against one another for the first time, and you want to have all your fluids clean. After this service it is standard to have your motor service either annual or every 100 hours, whichever comes first.
