POWERHEAD
ASSEMBLY
Test at least three corners of the rod and cap joint
with a pick. Joint must be smooth with no step.
Repeat steps for remaining connecting rods.
Crankcase
Thoroughly clean and degrease the mating
flanges of the crankcase and cylinder block with a
non-petroleum based solvent, such as isopropyl
alcohol or acetone, and let air dry.
IMPORTANT: DO NOT allow solvent to get on
internal components. Clean only the mating
flanges.
Apply Gasket Sealing Compound to lower oil seal
groove in crankcase. DO NOT put any sealer in
upper seal groove.
Use a small brush to dab a thin, even coat of Gel-
Seal II sealant to the crankcase mating flange.
The application must not come within 1/4 in. (6.4
mm) of seal rings or bearings.
IMPORTANT: Gel-Seal II has a shelf life of at
least one year when stored at room temperature.
Test the Gel-Seal II or replace it if the age of the
tube cannot be determined. Using old Gel-Seal II
could cause crankcase air leaks.
IMPORTANT: If Locquic Primer is used, crank-
case halves must be assembled and tightened
within ten minutes after the Gel-Seal II has been
applied.
Lower the crankcase into place. Confirm that
upper oil seal and lower seal housing are seated
correctly in grooves.
Apply outboard lubricant to the main bearing
screws and install screws finger tight.
When the crankcase is seated, install and firmly
seat the crankcase taper pin.
