What Engine Parts Should I Bring?

Hi All,

I have a question regarding engine and spare parts to bring on an extremely remote and cold voyage where access to mechanics and spare parts will be next to impossible. Also what are peoples thoughts regarding engine driven bildge pumps in case of emergency?

What are important spare parts to bring water pump, impellers, belts, oil filters fuel pump ????

Please check out our rare and remote voyage we would like your feed back at

Thanks !!!

You might want to mention the engine make/model.
Fresh and salt water pumps and/or rebuild kits.
Spare injector
head gasket
starter motor
gaskets/seals for water system and fuel system
hoses for water system
either a spare alternator or secondary method of electrical generation

Looks like a V***o MD2 on their website.
They make nice anchors!!!

Filters, pump kits, oils, injector and seals, full gasket set, hoses, alternator.
Being as your playing with icebergs maybe a spare prop.

Rather than an engine driven bilge pump take a separate engine driven salvage pump anything less than 2" and you'll struggle with a real leak.

Good luck with your plans, it looks like a superb trip
Arved fuchs has an interesting site about the trip.

Or both!

Approximate Flooding Rates, for smooth holes at selected depths, are calculated using the formula:
Flooding Rate in gpm = 20 x d x square-root of h
where:
d = diameter of hole in inches
h = depth of hole underwater in feet (head)

Hence, for a 2" dia hole at 3 Ft depth:
Q = 20 x 2" x root 3 = 20 x 2 x 1.73 = 69.2 gpm(4,152 Gal per Hour)
then
69.2 / 60 = 1.15 gal per second, or 2.3 gal in two seconds

Sorry its a Volvo Penta MD 11 C 23 hp. We are looking into a new one for the trip and will have a spare diesel outboard powerful enough to be our backup engine

Having the Penta MD17C, same thing almost. Our is running 6000 h now and we are on the way to the ice opposite of your route, Antarctic

I'll recommend bringing a whole new checked starter motor (and open up and check the one you have), rebuild the ignition key with a rely close to the motor. Without the startermotor it is hard to start the motor (!) even if there in theory is possible on the MD11 if you have strong arm and the handle that sometimes is still in the boat

Anodes for the heat exchanger if you have one (fresh water cooled), impellers (lots of them!) and packing material/liquid gasket, extra bolts to the impeller, a complete pre-pump (the one with the manual lever to pump diesel to the motor, said to be almost indestructible but I have manage... there is a new version, check that you get that one!) change ALL tubes before you go, and check the gearbox, most of them are bad. I had mine rebuilt before I took off and took a look at the parts inside.. bad!)

Make special tools to unscrew the bolts to the impeller (sometimes covered with tubes and hard to reach), make a ring-key 14 and cut an opening to loosen the spreader tubes with, hell to get those with a normal allen), bring green pain Change the small O-rings in the house where the start of the spreader tubes goes onto the aft of the motor, hard to get)

We found we needed extra ( lots of them) seals for the fresh water pump, filters of course, alternator, belts, any odd bolts etc, hoses for various things, exhaust etc.. your current mechanic is a good source of suggestions for what to bring. Good mechanics will know what they most received desperate calls about. We have a volvo MD 2 B. Thinking about repowering but the thing always starts, and never misses...so it continues on.

This is some great information. We are really thinking about replacing the engine now

I don't think you should be taking any spares more than a few hose clamps, spare oil, filters.

If your engine is not up to scratch or your knowledge appropriate then you should seriously consider going on an "extremely remote and cold voyage".

That is specialist stuff.

A spare starter motor and alternator is imho a woftam... waste of time and money. If you need one and not just a spare set of brushes (only for an old starter motor) you wouldn't have the knowledge to change it anyway.
A spare alternator is, again, a waste as you will have alternative power in wind or solar generator (in your case: wind)

if you are thinking about it, like reefing, it proably needed to be already done.
Get a new donk, plus all the attachments

Or a new boat fitted out properly with newish, low hour engine etc.

Modern engines (starter motors, alternators etc) don't really break down.... (*********Touch Wood!!*************)

Proof to the pudding is Auto Electrician shops.... very few these days

A couple of years ago, my boat was setting in a marina in the middle of winter and the ignition shorted out the ignition switch melting the brushes/commutator/bearing. It was 200 miles to the closest place to scavange for a starter so I found an outboard one that was close stole, epoxied, filed and fitted parts to work. My current spare. I agree a spare starter is a good thing. And if you think you have enough raw water impellers, get more.

If the engine runs well, has good compression, does not burn oil, then why replace it? I have a Volvo MD7a. About the same age. Recently the injection pump started leaking diesel fuel. The seals had deteriorated with age. It doesn't cost much to have the pump rebuilt, if you can take it off and reinstall it yourself. An additional benefit is getting to look inside the engine yourself during the process, so you can see if it has any carbon buildup, worn exhaust ports, corroded cooling system, etc.

I got my injection pump rebuilt, and the engine runs like new.

Most of the spare parts lists given above have to do with rubber things (or electrical windings) that deteriorate with age in a marine environment. It's really not too difficult a job to give that engine a thorough going over and check or replace all those parts. For that matter, it's not too difficult a job (from what I understand) to rebuild that engine yourself. Either way, it's a heck of a lot cheaper and easier than repowering. Plus you'll be much more confident about the thing if you sort of get intimate with it.

Much depends on engine age and make.

I would take:
- assortment of hoses,
- gasket material and cutters,
- anodes (if exist),
- filters aplenty,
- oil aplenty,
- raw water propellers,
- fresh water pump (if electrical one),
- alternator,
- starter,
- injectors,
- not least: a super duper set of applicable tools chosen so that you can disassemble and assemble every piece of the monster,
- engine manual (not the one we all have, the one mechanics use).

Much depends on how handy you are with engines. I am NOT ;-(
