Which engine?

[never monday]

I'm not here to discuss the pros of a 930 Vs a Miata. I stated that a supercharger and a turbo are equal. They both create free Hp.
That was off topic and I'll let it go.

AS far as spares and your story.
I disuade people from carrying expensive spares as much as posible. Starters, Alternators, injectors, IP's. these are all readily available.
Back to the original topic at hand.
The Volvo units mentioned are a 20hp-1cyl, a 30hp-1cyl and a 40hp-2cyl. After reviewing the specs on Volvos site I'd have to CHANGE MY OPPINION. In this instalation the 30 would be better than the 40. I try to stay away from 2 cylinder engines as much as posible. The vibration from the out of phase piston masses can be anoying.

The Volvo units are 3 cylinder (20Hp and 30HP) or 4 Cylinder (40HP).
Specificall D1-20, D1-30, D2-40

My mistake,
Volvo started using D? to state displacement. I regularly confuse it with Yanmar who states cylinders. Vibration won't be an issue with either. This puts the equasion back to money Vs. Hp. As I've been corrected so many times I'm going to reserve further comment.

My point is, you're down to one engine, you're in a remote spot, what do you do? You get to the next point of supply. You find they have to order your part. You find it is 4,6,8 times what you would have paid in the states. You pay, you wait in a spot you don't won't to be for another 2 weeks, you continue on. That works. Or, the heck with it, you continue on your cruise with one engine. That works too.

Been there, done that, got the tee shirt. Couple of them. It's a great club, you'll meet all kinds of people you might not have had a chance to meet! I even know I'll be there again. So, it comes down to captains choice, of course there is the admiral, who may just leave you there . You had guest coming in?? Oh, too bad, they can reschedule their tickets, don't they now what cruisings about?

Bottom line, it is mostly paridise and if you can keep in mind that you're mostly doing what you want to do, mostly where you want to do it, it's only money, its only a little time .

understood Strygaldwir. To each his, own and it does depend on where you are, experiences and so forth.

My point was, you are better off than a monohull-er that is carrying 'cold' spares, unless they are carrying TWO of everything.

(If I had guests coming they could hand carry the part!)
