PRODUCT DETAILS:
Direct replacement lower main bearing for Chrysler and Force 2-stroke outboard engines spanning 70 through 150 HP in 3-cylinder, 4-cylinder, and 5-cylinder configurations from 1977 through 1998. This bearing has multiple part numbers reflecting the long production history that spans the original Chrysler Marine era through the Force brand under US Marine and Mercury Marine ownership. Fits the 3-cylinder 70, 75, 85, and 90 HP models, the 4-cylinder 100, 105, 115, 120, 125, and 140 HP models, and the 5-cylinder 150 HP models in both 3.312 and 3.375 bore configurations. The lower main bearing supports the crankshaft at the bottom of the powerhead and proper bearing condition is essential for crankshaft alignment and engine reliability. A failing lower main bearing presents as engine noise, vibration, reduced power, or visible crankshaft play during inspection. Manufactured to match specifications for reliable performance in Chrysler and Force outboard powerhead applications. Always confirm your model and part number before purchasing to verify fitment.
