Injectors

I'm looking for some spare injectors for my Perkins 4-236. Any ideas on where or if there are equivalents out there? I would like to have a full spare set.

I don't care if they're rebuilt. I don't care if there OEMs. In my experience OEM isn't all it's cranked up to be. I do care that they function equal to or better than OEMs.

Thanks,
Fair Winds

I normally don't recommend carrying injectors in the spares box.

On most every Island there is a diesel shop should you need injector service.
The need for injector service on a normally maintained boat diesel should only need be checked every thousand hours or so. Injectors don't just fail. They are blamed for a lot of problems and usually don't fix what's ailing the engine.
Lastly, by the time you'll need injectors. The spares you've bought are nice rusty paper weights.

Thanks never on....

So what would you suggest as a good backup for offshore cruising and say basically a trade wind circumnav. Don't know how remote we'll be getting but assuming we do I want to be prepared.

Thanks and

For my engine spares. I have spare belts for the alternator. Thinking I need a spare lift pump, spare selonoid, spare starter, and spare zincs (I bought a bunch of those). Since engines are your forte' wondering what you would suggest.

Thanks,
Fair Winds

two areas to think about are the starter and the injectors.. Perkins are known for burning starters IF and I say IF the voltage is low and you start the motor.. thats one reason to dedicate one battery to starting the motor. injectors will go if you get some bad fuel with moisture in it.. nothing is worse on injectors than water.

Solenoid, Zincs, impellers, belts, oil pressure sending unit and a brass plug of the same thread. as many fuel filters as you can carry. If you have electric shut down, one of those solenoids. Lift pump, assortment of crush washers. a few ft of hose for all of your sizes.

By the time water gets to the injector and the engine stops he'll be repairing before corrosion can set in.

Pat is correct. Taking spare injectors and even starter for that matter, is going overboard. The list that Pat has given will be about right. I would like to add to it, Oil for both box and Eng.

If you do wish to take spares that are vulnerable to corrosion consider vacuum sealing them in a heavy duty plastic bag. Vacuum = no or minimal oxygen = no corrosion. If still worried fill bag with nitrogen or argon before vacuuming them and there definitely wont be any oxygen.

For metal parts it's a little simpler than that. Wrap them in grease and drop in the bag.

True on a modern engine, but my Perkins 4-108 recommends overhauling the injectors every 400 hours.

In addition to one spare injector I carry plenty of spare belts, impellers, a spare alternator, spare starter, spare heat-exchanger, spare head (complete except bowl), over haul kit for head, spare bilge pump, spare float switch, spare zinks for prop shaft, heat exchanger, rudder bearings, etc. Also spare water, oil, and fuel filters...And a bunch of other spare parts, can't even list 'em..Too long of a list..The boat is heavy and slow but she will get there adventually as there is a spare for just about everything that can go wrong.
