Re: i/o vs outboard pros and cons ??
It all depends on your boating preferances. I personally love our I/O for river, lake, and intercoastal boating. We spend a lot of time doing watersports, but also spend a lot of time just anchored off either in a lake or on a beach. We love the rear padded area, and we love the platform over top of the outdrive. We like not having that engine right in the middle in the way of the swim platform and our grilling out on the lake. It is super easy to maintain, takes all of about an hour to change engine oil, outdrive oil, and spark plugs, if that. About an extra 45 minutes to an hour if we are doing bellows. They are extremely easy to work on, Plus if we have a major engine failure, it is less than $2k to replace, and we are back up in about 2 weeks. About the same if we have a drive failure, maybe a little less. No way you will be doing those repairs on an outboard that cheap.
If I was going to be doing shallow boating, or offshore boating, I would certainly be looking at outboards, and I have. But for our boating, this is the best option. They both have their merits, and you have got to determine what is best for your boating and lifestyle. There is no way anyone will convince me either is better than the other.
