Tohatsu/Nissan Outboard Break-In Chart

4-Stroke Outboards
CAUTION: Four-stroke Tohatsu and Nissan outboards DO NOT come with engine oil already installed. You must add engine oil before attempting to start your four-stroke outboard for the first time. Failure to do so will result in extensive damage to your outboard. For more info see 4-stroke oil type and capacity.

Following the recommended break-in schedule will prolong the life of your new outboard and ensure optimum performance. RPM's should be varied throughout the break-in period without exceeding the maximum RPM limits as shown. We recommend that break-in be performed on the boat (under a proper load). For detailed information on the break-in procedure, please consult your owner's manual.

Note: This outboard is equipped with an Engine Oil Warning Lamp. When the warning lamp is off, it indicates that sufficient oil pressure is present. If the warning lamp is on (red light is on) or blinking on and off, immediately shut down your outboard and check the oil level. Replenish as needed. If oil level is at the appropriate levels, consult a Tohatsu or Nissan service center for assistance. Never run your outboard if the warning lamp is on or blinking on/off.

TLDI (Direct Injection) Outboards
