HAFTS
The shaft coupling is the connecting point
between the shaft and the engine. The alignment
should be set at a maximum of .005" (0.13mm).
A slight misalignment will cause loss of power,
excessive wear, noise and vibration and should
not be tolerated. When checking for parallel
coupling faces (the proof of proper alignment),
use a feeler gauge not more than .003 to .005 of
an inch thick (0.08 – 0.13mm).
With coupling faces brought together by hand –
not bolted – the feeler gauge should be tightly
gripped at all points around the edges of the
couplings. Next, hold the engine coupling flange
stationary and rotate the shaft coupling flange
90 degrees in either direction. The feeler gauge
should still be tightly gripped at all points around
the edges of the couplings.

The shaft log is a fiberglass tube which
provides an opening through the bottom of the
boat for the propeller shaft. The Strong Seal
™
is connected to it by a short length of special
flexible hose which serves to absorb normal
shaft vibration. The Strong Seal
™
prevents
water from leaking around the shaft and into
the boat. Shaft alignment and straightness
must be correct to assure proper operation of
the Strong Seal
™
. Refer to the Strong Seal
™
information for the seal carrier kit in the
Owner’s Manual packet.
