3 spare water
pump impellers and one spare endplate for same, perhaps bearing as well depending upon engine
. If the raw water pump
is not integral with the engine
manufactured carry a complete spare pump. Two spare fresh water impellers.
Spare injectors already set up by an injection shop for proper spray.
You may be able to get a "kit" from engine distributor with head gasket
, various other gaskets, "O" rings, rings, bearings, etc. which a mechanic
can use to rebuild
Case of fuel
filters for first filter, several for engine vacuum sealed.
filters vacuum sealed. Consider switching to a parasynthetic (compatible with regular oil) oil
for engine and transmission
oil changes giving you a 3X longer time between changes and, therefore, you don't have to carry as much engine oil.
Set of engine mounts (note that Yanmar
has different part #s for port vs. stbd mounts for torque reasons and the rubber stiffness is different).
Two spare sets of alternator
belts and water pump belts.
If you add a large case alternator
to charge your house batteries leaving the stock alternator merely to drive the engine electrics the belt it will last for more than a year and alternator bearings for the engine will last for around 5000 to 8000 hours perhaps, otherwise carry spare alternator. You can get spare bearings and brushes
and diodes for large case alternators which you can rebuild
yourself with a little knowhow AND if you carry this small kit you probably woun't have to use it!
If you use a "high voltage" start battery
(like the Optima) and have low resistance cabling to the starter you should not need to replace the starter or its solenoid for 8000 hours or more!. Most starter failures are due to corrosion
or abuse by cranking with a low voltage which may double or quadruple the wear and heating
. Keep in mind that owners of diesel
engines who keep care of them get years and thousands of trouble-free miles. Only yachties, in general, have troubles due to neglect and poor installations.
Check on line for others with your exact engine model number for specifically related spares required beyond the usual as mentioned above.
People with engines that have raw water
heat exchangers for cooling
oil should carry a spare heat exchanger
Don't forget the zincs if you have engine zincs Spart throttle and shift cables
. Spare "bulk" fuel
line long enough to replace all of your flexible fuel lines. Spare "bulk" water hose. Spare multiple hose clamps--hich quality....see Gord's recommendation.
Many people should consider carrying a spare pressure plate (there are other names) which absorb the shock of putting the transmittion in gear
KNOW how to realign one, and have the necessare special devices to properly keep it concentric with the engine when reassemblig or else you will scatter the springs out of the new one in short order. Not all mechanics pay sufficient attention to this detail.
For long trips carry a spare exhause elbow
if yours is the type that is where the raw water
enters the exhaust
system. If you spend the extra money
on the high-tech silicone-type exhaust
hose you can store it easily because it bends WAY better that the normal stiffies. They also take much higher temperatures before exhausting themselves.
I'm sure the others here will find what I"ve missed (I hope).
