E) Once even spacing is measured all around the flange, rotate the shaft 1800. If a significant
mismatch occurs, your shaft is bent and must be straightened or the coupling face is out of square
with the shaft centerline and must be machined to correct.
F) Replace bolts and evenly tighten.
6.5) Propellers:
The standard propeller supplied with all Endeavour models is a solid bronze, two-bladed type. It has a
tapered bore that mates to a tapered shaft end and is held in place with two locking nuts and a cotter
pin. A square key locks the propeller to the shaft preventing any rotational slippage of the prop.
The hydraulic transmission on the diesel engine in the E-40 foot model cannot be locked and the
propeller will free wheel at any gear shift position. According to the engine manufacturer, this will not
cause damage but the slight noise from the rotating shaft may be an annoyance to you. A commercially
available prop shaft lock can be fitted to correct this and is highly recommended if long range cruising
is anticipated.
The standard propeller size is 17x17 R.H. two blade; the optional propeller size is l7xl6 R.H. three
blade.
6.6) Removal of Propellers:
A wheel puller or prop puller is required. This is available from automotive or marine hardware
dealers.
To remove a propeller, proceed as follows:
A) Remove the cotter pin and shaft nut.
B) Leave the propeller retaining nut in place but installed about one or two turns loose from the tight
position (to protect the threads). The puller shaft should bear directly on the end of the propeller
shaft or on the propeller retaining nut. If it bears on the propeller retaining nut, a spacer of brass,
aluminum, or copper should be used to protect the nut. The puller must be installed straight and
centered care-
fully so that its maximum effectiveness can be realized. Place the claws of the wheel puller behind
the propeller hub.
While pulling the hub, it is often a help if the propeller hub is tapped with a composition hammer. If
the propeller has been on for some period of time, some effort may be required to remove it.
6.7) Installation of Propellers:
Ensure that the bore of the propeller is free from and corrosion and that the end of the shaft is clean.
The keyways of the propeller and shaft must be free from burrs. Place the propeller on the shaft with
the keyways in the shaft and propeller in line. The key should fit as snugly at the sides with a .01”
minimum clearance at the top. Do not force the key in as this may cause the propeller to be forced off
center. The propeller, the locking nut, and the cotter pin are then assembled on the shaft. Check to
ensure that the propeller is correctly aligned.
6.8) Propeller Alignment:
Install the propeller completely as to be used.
Clamp a piece of thin metal or wood on the propeller strut
or skeg to touch one blade edge of the propeller. Rotate the shaft and the propeller by hand. Any
variance in the track will be indicated by either a gap between the next blade or the blade striking the
indicator. If the propeller is so indicated to be out of line, it should be checked and balanced by a yacht
marine yard familiar with this type of work.
