Nope, not a bad thing to lose the engine as such. Where the issues come in, is for those visiting some out of the way, 3rd world countries and then have the engine die. You can have great difficulty in obtaining expertise, the correct part and the cost can be an issue. Even ordering from your home country, can take an eternity to get the part to where yoiu are, and then, you have to be absoutly sure you ordered the correct part, or something different turns up and you go through the entire process again. Hmmm, now where have I read issues like that just recently
So it is being a little self sufficient that the answer lies. Of course, you do have to draw a line somewhere, or you may as well just tow behind you a compleate nother boat. Just what IS carried is up to the individual and his/her expertise in repairing possible problems from No.8 fencing wire and Bailing Twine As we kiwi's like to say. Actually our saying is more acurately, "If No.8 can't fix it mate, nothing can"
Plus room. Depending on boat size, storage
space is alway's an issue, and you have to draw a line as to spares somewhere. And remember, it isn't JUST the engine spares you need to worry about.
