OPERATION

Setting Trim Angle While Running Engine at Idle Speed
The exhaust relief hole on the outboard may become submerged if the outboard is trimmed full-in while running at
idle speed. This will cause exhaust restriction, rough idle, excessive smoke, and fouled spark plugs. If this condition
exists, trim the outboard up until the exhaust relief hole is out of the water. The outboard should be lowered for
accelerating from a standing start or from idle speed.
CAUTION
Severe damage to the engine can result by not complying with the Engine Break-in Procedure.
GASOLINE/OIL BREAK-IN MIXTURE
Models with Electronic Fuel Injection (EFI) - Do not use pre-mixed gas and oil during break-in. Oil from the oil
injection system will supply adequate lubrication during engine break-in.
Models with Carburetors - Use a 50:1 (2%) gasoline/oil mixture in the fuel tank for the first 114 liters (30 gallons)
of fuel.
BREAK-IN PROCEDURE
1. For the first hour of operation, allow the engine to warm up for 30-60 seconds.
a. Run the engine at varied throttle settings, the majority of the time between 3000 and 4500 RPM or
three-quarter throttle.
b. Change engine speed approximately every two minutes, and avoid continuous operation at idle speed
for more than ten minutes. Short bursts of full throttle for periods up to ten seconds are acceptable.
c. Avoid trimming the outboard out (up) beyond a vertical trim position during operation.
NOTE: It is the driver's responsibility to always drive in a safe manner. Improper trim angle of the outboard when
driving at speed can be difficult and dangerous. The purpose of specifying trim angle is to help guide the operator
in determining how to put the propel load on the engine. They are intended to be guidelines and do not suggest
or require unsafe boat operation.
2. For the next three hours of operation, change engine speed every ten minutes.
Starting The Engine
Before starting, read the Pre-Starting Check List, Special Operating Instructions, and Engine Break-in Procedure
in the Operation Section.
CAUTION
Never start or operate your outboard (even momentarily) without water circulating through all the cooling water
intake holes in the gearcase to prevent damage to the water pump (running dry) or overheating of the engine.
1. Lower the outboard to the vertical operating position. Make sure all cooling water intake holes are submerged.
