Propeller Shaft
(MIE Inboard Models)
The following information can be used as a
guide for determining vibration problems
on boats powered by inboard engines (MIE
models). For installation, alignment and re-
pairs to shafts, struts, shaft logs and rud-
ders, refer to boat manufacturer's service
manual. If boat is equipped with V-drive, or
a remote mounted V-drive, refer to Section
8B or boat manufacturer's service manual
for all servicing and troubleshooting. For
MIE engine installation and alignment, re-
fer to Sections 2E and 2F.

Checks Made with Boat In Water

1. Disconnect propeller shaft coupling from trans-
mission coupling.
2. Check fit of coupling to propeller shaft.
Straight Bore Type:
a. Loosen set screws.
b. Try to move coupling by hand. The bore of the
coupling should be a semi press fit to shaft.
c. Check shaft for wear. If worn, replacement of
shaft may be necessary.
d. If shaft is not worn, try another coupling.
Tapered Bore Type:
a. Check nut on shaft for tightness.

b. If nut was loose, remove coupling and check
for damage to taper on shaft or in coupling.
c. Replace worn parts.
d. Always make sure key is not sticking out of
coupling.
e. Install coupling on shaft without the key.
f. Mark the shaft (behind the coupling), then re-
move the coupling.
g. Now install the key and coupling. Make sure
coupling still lines up with the mark. This en-
sures that key is not oversize and holding the
tapers apart.
