What's the Project Life for my Honda BF40?

[Atlantic Bryan]

I've got a BF40 that I purchased new in 2004. It's now got about 700 hours on it. It lives in salt water and is used pretty much daily winter and summer in Nova Scotia. Individual trips aren't long ... usually only 10-15 minutes. I'm pretty good about following Honda's recommended service intervals (except that not much gets done in mid-winter) and so far it runs like a champ. I'm curious as to whether my motor has days to live or decades.

Thanks for your advice.
