Engine maintenance for circumnavigation?

[Kwik Decision]

Maybe fit an exhaust temperature alarm or piddler tube in front of the helms view?
If you get a water inlet blockage/failed impeller then in theory by the time the engine overheat alarm goes off, plastic water mufflers, water hoses, exhaust hose ‘ might’ be a bit cooked.

Excellent suggestion. I fitted one of these on our boat a few years ago, and thoroughly recommend them:

I've witnessed the aftermath of cooling water failure without such an alarm. By the time the engine overheat alarm went off, a hole had been melted in the plastic silencer box. The blockage was quickly removed, and the engine re-started, only for the bilge alarm to go off a couple of minutes later...

I did fit an exhaust temperature, but I removed it and fitted a raw water flow switch that would alarm if the raw water flow stopped

This would indicate potential over heating before any engine damage can take place

Unless you are planning to motor all the way I would just take a basic spares kit like filters. Your engine is pretty common world wide so spares would not be an issue. I would concentrate on the sails and rigging making sure all is well, which I'm sure you have done.

Until you find they're not.

Viz trying to source a D1-30 head gasket on the west coast of Scotland. So I'd definitely be carrying a full set.

Parts4engines appear to have the full gasket set available for the D1-30 including the head gasket for next day delivery. I also think I'm right in saying that the D1-30 is based on the the Perkins 403-11 and if you search for this or the original part number for the gasket (111147570) you will find plenty of EU based suppliers that will send it to you in a few days.

You might consider taking some injector nozzles.

Injector nozzles?
If you lot suggest much more the Op would be better off just taking a spare engine

Personally, I would check the HP sauce
Cannot seem to get HP sauce anywhere outside the UK

My boat, which has sailed afar, came with a spare oil cooler above the gearbox. They cost about £250 quid new. Not sure how at risk an oil cooler is, but failure would limit the use of the engine, even if bypassed.

I would not do a cooling system or oil system flush, if there is no evidence that the engine needs it.


If I can’t find parts in the UK I go to Transatlantic Diesel, in USA.

Sure - I use Parts4Engines a lot.

But sometimes 'in a few days' means you miss a weather window, or engineer availability, or other external constraint kicks in and makes life complicated. So having a set on board removes that worry. They're not exactly bulky!

I have to say that I got the message from the first post. I assumed that your casual response merely reflected your usual approach to sailing problems, something that I probably share myself, and look where that got us.

Given there has been a healthy thread about UK Circum ... I don't think DB is only one to assume UK ... I know I did as well ......

Also, as the OP talks about a RTW trip, in several countries customs procedures can be veeeeery long even for Tom Hanks at FedEx, long meaning weeks and weeks, I found a lot better to be self reliant as much as possible. People 'waiting for spares' for weeks are a very common occurrence.
Examples
A friend in Salvador Brazil was sent two new generators by the boatyard (it was Lagoon first attemp at an electric boat, so they were giving full unconditional support to the boat, regardless of cost), the equipment arrived in Sao Paulo a few days later, queued in Custom procedures with unknow availability date, a few weeks later the recipient was asked to travel there to be able to clear and take possession of them, yeah 4k+ kilometers with two 50kg machines The boatyard accepted to just forget them and sent another two machines in another country.
Another friend in Gambia had a fishing line around the stuffing box, after asking locally about delays, his wife preferred to travel return to the UK to collect the spare.
French Guyana, I needed a new headstay, despite the fact that they send space rockets no one could make one, I wanted to buy it in mainland France but locals said 'forget it, Douanes are on strike you'll have to wait at least a month to have them cleared' (France Overseas Departments are a different custom territory).
Besides cruising being 'doing maintenance in exotic places' I'd add 'waiting for spares'

No one seems to have mentioned hoses and belts. A set of these would make sense.

I wasn't saying not to carry a spare gasket set, just that it should be easy to get hold of a head gasket for a D1-30 on the West Coast of Scotland as it sounded like you had been struggling!

Perkins is owned by Caterpillar and our local caterpillar agent supply all Perkins spares so should be available worldwide
