Mercruiser V-Drive Alignment - Regal 3760 Owner's Manual

ELECTROLYSIS PROTECTION
Sacrificial zinc anodes usually found on the engine
driveshaft, rudders, and trim tabs to protect softer metals
exposed to the water. Electrolysis attacks the least noble
metals first. Because zinc is a less noble metal, it will
decompose before other metals. Check these zinc anodes
periodically and have them replaced when they are 50%
gone.
Zinc is also used to protect metal that is exposed to
saltwater. The salt causes a galvanic action that
decomposes metals.

MERCRUISER V-DRIVE ALIGNMENT

V-drive engine alignment should be left to a qualified
marine technician. Alignment should be checked after the
first 50 hours of operation and on an annual basis
normally on recomissioning. Also, it should be checked
whenever alignment may have shifted due to grounding
or striking something underwater, or after the vessel has
been lifted or launched. Angular misalignment is corrected
using the adjustments in the engine mounts. The coupler
faces must be parallel within .002 inch.
Note: Do not attempt the alignment procedure yourself
since drive train/engine component damage will result
from misalignment. Contact an authorized Regal dealer
for more information.
