! CAUTION
Pressurized fuel system! Release all pressure before servicing any part of the fuel
system. This system can build pressure if the engine has not run for an extended period
of time. If the fuel system is not relieved of pressure, fuel and vapors may be expelled at
a significant velocity. Always protect your eyes and skin from pressurized fuel and vapors
when servicing the fuel system.

Cylinder Head Removal
IMPORTANT: The removal and disassembly procedure of the cylinder head and cams
must be strictly followed. Failure to follow the removal procedure may damage the valve
train components.
IMPORTANT: Do not inter‑mix the location of the valve train parts.
IMPORTANT: This engine is an interference valve train design. Do not rotate the crankshaft
or cams when the timing chain is loose or removed from the cam gears unless advised to
do so. Failure to adhere to this important information will result in valve or piston damage.
1. Remove the bolts securing the cam cover to the cylinder head.
2. If necessary, rotate the crankshaft with the flywheel so the timing marks are in

Cleaning, Inspection and Repair
Measuring Cylinder Bore
Measure the cylinder walls for taper, out of round or excessive ridge at the top of the ring
travel. This should be done with a cylinder bore dial indicator or an inside micrometer.
Carefully move the gauge up and down the cylinder bore to determine taper. Turn the
gauge to different points around the cylinder wall to determine the out of round condition.
Page 4A-36
90-899185 SEPTEMBER 2006

Powerhead Pre‑Assembly Cleaning Recommendations
IMPORTANT: Any threaded hole or bolt with thread‑locking compound that is
contaminated with oil, must be thoroughly cleaned with a solvent to remove all traces of
oil contamination. Failure to remove oil contamination will result in poor thread‑locking
compound adhesion.
Prior to assembling the powerhead, all threaded holes on the cylinder head and cylinder
block must be cleared of thread‑locking compound dust. Use compressed air to clear
thread‑locking compound dust.
Wash the cylinder block and crankcase cover with hot soapy water to remove debris and
honing compound. Dry the cylinder block with compressed air. Failure to thoroughly clean
the cylinder block of honing compound and/or debris will result in premature engine failure.

NOTE: When reading the crank pin bearing journal grade on the crankshaft, the journal
grade is in sequential order from P1 to P4 in a clockwise orientation.
NOTE: When reading the main bearing journal grade on the cylinder block, the journal
grade is in sequential order from the top main bearing to the bottom thrust bearing.

Main bearing oil clearance
0.014 ‑ 0.042 mm (0.0005 ‑ 0.0016 in.)
IMPORTANT: Ensure all mating surfaces, oil passages, water jackets and cylinder bores
are clean prior to assembling the powerhead. Always install new gaskets, seals, O‑rings,
piston ring and wrist pin retaining clips. Replace torque to yield screws where advised to
do so. Follow all advised lubrication during assembly.
1. Check the crankshaft journal size code and the cylinder block main bearing code.
2. Refer to the bearing selection chart to select the correct crankshaft main bearings.
90-899185 SEPTEMBER 2006

Piston Ring Installation
IMPORTANT: Do not reuse the original rings during reassembly. Always install new rings
when rebuilding the engine.
IMPORTANT: Use caution when installing piston rings to avoid scratching the piston.
1. Apply Synthetic Blend 4‑Stroke Outboard Oil 25W‑40 engine oil to the piston ring
grooves.
2. Install the oil ring spacer onto the lower ring groove of the piston.
NOTE: Ensure the oil ring spacer gap is properly orientated on the piston. The oil ring
spacer cannot be rotated after the bottom and top oil control rings are installed.
3. Install the bottom oil control ring.
4. Install the top oil control ring. The top oil control ring uses a locating pin on the piston.
5. Install the second compression ring.
6. Install the top compression ring.
7. Position the piston ring gaps as shown.

Installing the Camshaft Gears and the Timing Chain
! CAUTION
This engine is an interference valve train design. Do not rotate the crankshaft or cams
when the timing chain is loose or removed from the cam gears unless advised to do so.
Failure to adhere to this caution may result in valve and/or piston damage.
IMPORTANT: The removal, disassembly, reassembly, and installation procedure of the
head and cams must be strictly followed. Failure to follow the removal procedure may
damage the valve train components.
1. Install the timing chain on the intake cam gear. The anodized link of the timing chain
must align with the timing mark on the cam gear.
2. Install the cam gear on the intake cam. Rotating the crankshaft a few degrees may
ease the installation of the timing chain/cam gear onto the cam. Secure the cam gear
with the cam gear screw and washer. Do not tighten the cam gear screw.
NOTE: Cam gear screws are left hand thread.
3. Place the exhaust cam timing gear in the chain, ensuring the timing mark on the cam
gear and the anodized timing chain link are aligned. Install the cam gear with the timing
chain onto the exhaust cam. Secure with the cam gear retaining screw and washer.
Do not tighten the cam gear screw.

NOTE: It may be necessary to gently rock the powerhead once the powerhead mounting
studs are partially through the adapter plate.
7. Remove the lifting tool from the flywheel. Install the flywheel grease cap.
8. Install two nuts onto the aft powerhead mounting studs. Do not torque to specification
until all of the powerhead mounting nuts and bolts are installed.

studs. Do not torque to specification until all of the powerhead mounting nuts and bolts
are installed.

IMPORTANT: You must calculate the torque value of the nuts securing the powerhead to
the adapter plate when using an extension tool.
a. On beam type torque wrenches, measure from the square drive to the fulcrum
(pivot) point of the handle. Follow steps d through g.
b. On electronic digital type torque wrenches, measure from the square drive to the
center of the handle. Follow steps d through g.
c. On click‑stop or dial type torque wrenches, adjust the torque wrench to the
specified torque. Determine the effective length from the square drive to the center
of the handle. Follow steps d through k.
d. Measure the tool extension from the center of the square drive to the center of the
nut drive. The Torque Adapter Tool length is 30.48 cm (12 in.).

Add the torque wrench length and the tool length to find the sum.
Divide the sum by the torque wrench length to find the quotient.
Divide the torque specification by the quotient. This is the torque specification for
the nut or bolt.
Adjust the torque wrench to reflect the new torque calculation.
For greater accuracy, redetermine the effective length of the torque wrench and
the extension tool with the new torque calculation.
Compute for the corrected torque setting.
Adjust the torque wrench to reflect the second new torque calculation. This is the
final torque specification for the aft powerhead nuts when using a click‑stop or dial
type torque wrench.

Engine Break‑in Procedure
! CAUTION
Severe damage to the engine can result by not complying with the Engine Break‑in
Procedure.
1. For the first two hours of operation, run the engine at varied throttle settings up to 4500
RPM or at three‑quarter throttle, and at full throttle for approximately one minute every
ten minutes.
2. For the next eight hours of operation, avoid continuous operation at full throttle for more
than five minutes at a time.
