10
years of economical, dependable service. Specific technical questions regarding your engine may be
answered by your dealer.
6.2) Transmissions:
The diesel of the 40-foot model is fitted with a mechanical drive. To ensure trouble-free operation of
the clutch, only use oil of the recommended type. Under no circumstances should the oil contain any
additives such as molybdenum sulphite. We recommend commercial Automatic Transmission Fluid
(AFT), Type A.
Check the oil level in the gearbox about once a month. Correct oil level: index mark on dipstick.
Always use the same oil grade when topping up. Change the oil for the first time after about 25 hours
of operation, the; at intervals of at least 1 year.
6.3) Propeller Shaft and Stuffing Box:
All models have solid stainless steel propeller shafts. The diameter of the E-40 shaft is 1¼”.
The propeller shaft is supported at the inboard, or engine end, by the shaft coupling. A square key is
used to prevent turning of the shaft in the coupling. In addition, a stainless steel bolt with locking nut
passes through the coupling and shaft to prevent backing out of the shaft in reverse.
The shaft passes through the hull at the stuffing box. Water tightness is ensured by the packing
material in the stuffing box. A slight dripping, say three or four drops per minute, under power is
normal and desirable. Always tighten the packing nut (farthest forward) by hand, never with a wrench.
The locking nut (aft) can be wrench tightened against the packing nut to lock the system in position. It
is important to never over tighten this stuffing box as excessive twisting loads will be placed on the
rubber hose between the stuffing box and shaft log. In extreme cases where the stuffing box would be
virtually locked to the shaft by over tightening, the rubber hose could be ripped apart allowing sea
water to enter.
The packing material should be changed annually to ensure trouble-free service. Packing of the proper
size is available from most marine hardware stores. The E-40 takes 3/16” square packing. Cut packing
in three or four individual rings, rather than a long spiral, to prevent binding on the rotating shaft.
The prop shaft on the E-40 foot model is supported at the aft end by a cutlass bearing mounted in a
stainless steel shaft log bolted to a fiberglass skeg immediately aft of the keel. The skeg is integrally
molded with the hull.
All cutlass bearings can be removed for replacement by loosening the allen head set screws and either
driving the bearing out from one end or, in difficult cases, sawing it into three lengthwise sections with
a hacksaw blade and prying them out. The replacement bearing should be a light drive fit. Light
hammer taps should be sufficient to drive in place. Sand or lathe turn the outside of a replacement
bearing to obtain the proper fit. Replace the alien screws when in place.
6.4) Shaft Alignment:
All new Endeavour yachts are shipped with the shaft coupling disconnected to ensure that alignment is
performed after delivery. All molded fiberglass boats will change shape slightly when launched,
causing the relationship between the engine and propeller shaft to change. It is essential to align the
shaft coupling only after launching, especially with new boats.
Alignment is checked in the following manner:
A) Remove the bolts on the shaft coupling.
B) Slide the couplings together by hand.
C) Use a feeler gage or paper-thin metal sheet to check that the gage is gripped with equal friction
completely around the circumference of the coupling faces.
D) If the feeler gage does not pull evenly around the entire coupling, the engine is misaligned. This is
corrected by adjusting the mounts on all four corners of the engine.
