Measuring Shaft Length

Please be sure to measure your drive shaft when checking stock or placing an order. Measure from the top of the shaft to the mating surface of the gear housing. 18" = Short Shaft (15"), 23" = Long Shaft (20"), 28" = Extra Long (XL, 25"), 33" = Extra Extra Long (XXL, 30").

Core Info

Core value is primarily based on the condition of the housing, prop shaft, and drive shaft. You'll receive a core-return label for sending your old unit back for credit -- do not return a core without the proper label.

Old style 150 XR4 and XR6 lower units with 4.25" diameter propeller hubs do not have any core value.

New Units

New gearcases are not OEM-boxed; they're either re-boxed OEM, or assembled with all new parts, depending on availability.

Three-jaw lower units aren't available new. You can upgrade to a 6-jaw unit, but you'll need to purchase a new shift rod from a Mercury/Mariner dealership.

3.0 Liter Units

Please specify whether your drive shaft has 9 or 13 splines on the drive shaft.

Caution!

All units are shipped without oil. Be sure to use the proper gear oil and filling procedure in your owner's manual.
