Service Manual 15-30 HP E-TEC Installation And Predelivery
Wedge a block of wood between propeller blade and the anti-ventilation plate.
001992
Install the propeller nut and tighten to a torque of:
• 120 to 144 in. lbs. (13.5 to 16.5 N•m)
If cotter pin holes in the nut and shaft do not align, tighten further. Do not loosen. Install new cotter pin.
IMPORTANT: After installation, make sure out board is in NEUTRAL and carefully spin propeller. Propeller must turn freely and should not spin off center. If propeller appears to wobble, check for possible bent propeller shaft.
WATER TEST AND FINAL ADJUSTMENTS
An in the water test is required to make sure the outboard(s) and boat are rigged correctly, propeller selection is correct, and that all accessories function properly.
Pay special attention to the following, especially if the boat is repowered with new outboard(s):
• Engine mounting height
• Correct propeller selection and WOT RPM
Make all needed adjustments or repairs and retest before delivery.
When ready for delivery, give all instruction sheets, operating instructions and user guides provided with accessories to the owner. Advise the owner of any special operation or maintenance information contained in the instructions.
IMPORTANT: Complete the Predelivery Check list and obtain owner’s signature at the time of delivery. The Predelivery Checklist must be kept on file for seven years.
Engine Mounting Height Adjustment
Goals include:
• Engine RPM within the full throttle operating range
• Best acceleration and top speed
• No excessive ventilation while boat is coming onto plane.
Start with the engine lower on the transom. Make a test run, taking note of engine RPM, water pressure, trim level and boat speed.
Raise the engine and repeat the process until the best acceleration and boat speed are achieved.
Trim Sending Unit Adjustment
The sending unit eccentric cam must be adjusted so that the gauge needle is aligned with the lowest gauge mark with the outboard trimmed all the way DOWN.
- Lowest gauge mark DR2827
Check if the gauge needle is above or below the lowest gauge mark. Tilt engine UP and engage trailering lock.
- Trailering lock 18954
To avoid personal injury, do not adjust the sending unit eccentric cam while the
engine is being tilted.
When the outboard is trimmed all the way DOWN, the sending unit lever touches the eccentric cam just forward of the top of the cam at the contact point.
Loosen cam screw and rotate eccentric cam to adjust full down gauge position:
• If the needle was above the lowest mark, move the thick part of the cam TOWARD the contact point. Tighten the screw, and recheck the gauge reading.
• If the needle was below the lowest mark, move the thick part of the cam AWAY from the contact point. Tighten the screw, and recheck the gauge reading.

Tighten eccentric cam retaining screw and check needle position at full trim DOWN.
Trim Tab Adjustment
Improper trim tab adjustment can cause difficult steering and loss of control.
A propeller will generate steering torque when the propeller shaft is not running parallel to the water’s surface. The trim tab is adjustable to compensate for this steering torque.
IMPORTANT: A single trim tab adjustment will relieve steering effort under only one set of speed, outboard angle and load conditions. No single adjustment can relieve steering effort under all conditions.
If the boat pulls to the left or right when its load is evenly distributed, adjust the trim tab as follows:
• With the remote control in NEUTRAL and the engine OFF, loosen the trim tab screw.
• If the boat pulled to the right, move rear of the trim tab slightly to the right.
• If the boat pulled to the left, move rear of the trim tab slightly to the left.
Tighten the trim tab screw as follows: • 15 – 30 HP: 60 to 80 in. lbs. (7 to 9 N·m)
- Trim tab screw 007044
Test the boat and, if needed, repeat the procedure until steering effort is as equal as possible.
Outboards with High Transom Heights
The trim tab may be above the surface of the water when the outboard is trimmed out. Steering effort might increase. Lower the trim setting to submerge the trim tab and to reduce steering effort.
