The Service Bulletins listed below are those that may be important to Nevermore maintenance and operation.
The first set are in the engine Tech Manual; we may just list the "important" ones, but now (Oct07) are erring on the side of listing too many. They seem to have been selected for inclusion in the tech manual because they refer to the W50 engine, while we know that all bulletins are identified in ONE sequence of numbers for all engine models.
The second set (only one bulletin, #130) was found in Nevermore's papers, and appears to be important.
The third set is a selection from a list of all bulletins starting with Bulletins #20 and #49, then appearing somewhat more complete starting with #101. No rationale for skipping some, including the "important" (#130) one found in Nevermore's papers, can be deduced.
- in Technical Manual Westerbeke 50 Marine Diesel Engine
- Pub #23156, Ed. One, June 1978
SB# Service Bulletin Date page
--- ---------------------------------------------------- -------- ------
020 Svc.Bull. #20: Oil Pressure Sensing __/__/__ p:V.2
don't remember what this is actually about
TODO: look it up
069 Svc.Bull. #69: Exhaust System _____ failures? __/__/__ p:V.3
TODO: what's this about
072 Svc.Bull. #72: Gauges -vs- Senders non-Interchangeability __/__/__ p:V.4
4 different manufacturer sources for instruments gauges
require matching senders; outlines of the different
gauges are given
076 Svc.Bull #76: Bleeding Hydraulically Governed Fuel
Inj Pump (if fitted) 08/27/75 p:V.5
special procedure for anti-stall device to hold the
locknut in position when opening bleed screw for this unit,
because the locknut setting determines the adjustment
of the anti-stall feature; losing that adjustment
may not let engine start, even after bleeding.
081 Svc Bull #81: Muffler (don't remember subject) __/__/__ p:V.7
TODO: look up why we remember this?
082 Svc Bull #82: Battery Recommendations __/__/__ p.V.9
084 Svc.Bull #84: Heat Exchanger Rubber End Cap Positioning 09/04/75 p:V.__
reassembling heat exchanger requires a particular
alignment of end cap on the exchanger body
087 Svc.Bull #87: Alternator Output Splitter 09/18/75 p:V.__
optional splitter discussed; might require rewiring
where charging voltage is taken from the alternator
(from regulator output rather than "generator" screw)
Note: We don't think Nevermore has this optional device (Sep07)
but it IS included in engine 12-v electrical diagrams.
2-way splitter P/N 20654, alternator max 120-amp,
will give charging voltage approx 0.8-V less than usual.
092 Svc.Bull #92: Troubleshooting W.T. and O.P. Gauges __/__/__ p:V.__
gives some step-by-step tests, and a couple
admonitions about what NOT to do
094 Svc.Bull #94: Fuel Pressure Switch Installation 09/09/76 p.V.15
Thom remembers this as discussing how to ADD switches
and locate them if more switching is required;
also remembers this is where we got insight into
the one switch we do have, and the implementation of
the "keyless" ignition Nevermore has
in loose form among papers MIT received with Nevermore Aug07
SB# Service Bulletin Date --- ---------------------------------------------------- -------- 130 Svc.Bull #130: On Engine Fuel System - Bleed Procedure 12/08/83 Westerbeke W50 P/N 33547 gives steps for bleeding the fuel system, "after air has been bled from that portion of the fuel system between the fuel tank and engine...", picking up with purging air from the secondary filter. Then it gives steps for starting the engine. Note that this Svc.Bull. did NOT appear on the web list below.

SB# Service Bulletin Date
--- ---------------------------------------------------- --------
104 Service Bulletin #104: S.W. Pump Pulley Set Screw
- Westerbeke 30 & 50 01/22/80
make sure waterpump pully set screw #11357 must be tight!
107 Service Bulletin #107: Thermostats
- All Models 05/01/80
>=May 1980, bypass hole allows some water circulate
during warmup; this flow is mandatory, so use genuine
Westerbeke thermostats
114 Service Bulletin #114: Water Heater Installation
- All Marine Engines 05/06/82
use of Westerbeke FLOWCONTROLLER in hot-water circuit
to allow suffient flow for users, but also good circulation
for engine. Also lots of considerations of not having
trapped air (use continuous slope from WH to engine, or
install bleed petcock; avoid loops in tubing trapping air.
Also: FLOWCONTROL kits available to retrofit late 1980-82
W. engines; different for manifold on left or right side.
121 Service Bulletin #121: Shift Cover Sealing
- All Marine Propulsion Engines 03/18/83
- for HBW xmissions, like type that Nevermore has
the moral for us is that we shouldn't mess with this cover!
however, our xmission was probably made BEFORE this change?
Shift cover put on now (>= 03/18/83) with orange loctite,
replacing use of gasket #22207; warranty broken if this
cover is removed..."
125 Service Bulletin #125: Oil Pressure Switches
- All Models 08/14/83
TODO: check whether we have hex shaped case with
indented corners, need special wrench socket
132 Service Bulletin #132: Manufacturing Date Code
- All Models 11/08/83
SUPERCEDED BY Svc.Bull. #242
136 Service Bulletin #136: Shift Lever
- All HBW Transmissions 02/09/84
Thom thinks this is applicable to Nevermore
this is for HBW (Short Profile Sailing Gears)
148 Service Bulletin #148: Tachometer
- All Propulsion Engines 01/23/85
probably pertains to Nevermore
TODO: check part-number of H'more's tach to 11917 here
153 Service Bulletin #153: Fuel Pick-Up Screens
- All Models 04/13/85
don't know if we have a screen
162 Service Bulletin #162: Exhaust Elbows
- All Models 02/28/86
don't know if we HAVE "locally fabricated exhaust elbow"
239 Service Bulletin #239: Transmission Lubricant Change
- All PRM80 and PRM 120 Transmissions 10/27/03
NOT Nevermore we think change from hvy oil -> ATF (Dexron III)
TODO: put ref here how ThomS KNOWS our xmission uses Dexron anyway)
242 Service Bulletin #242: Manufacture Date Code
- All Models 08/20/04
SUPERCEDES Svc.Bull. #132 dated 11/08/83
TODO: compute date based on Nevermore's engine number
BUT:: maybe we SHOULD use Svc Bull. #132, since our engine
was manufactured before that Bull's issue date
(or wasn't there info in pubs that came to us with Nevermore
of how to determine manufacture date?)
