Re: I/O vs outboard
Morrisy18 I currently own a 1977 Merc 150 Outboard and a 1988 Mercruiser 4.LX sterndrive. I have peviously posted a long discussion on the merits/drawbacks of both. The readers digest version is:<br /><br />Outboards use more fuel, are a bit noisier, and have more power per pound. They also need much less periodic maintenance and spare parts.<br /><br />Sterndrives are quieter, idle much better, usually have better low-end power and less top end. Sterndrives need engine waterpump, alternator and starter replacements much more often than outboards, as well as normal replacement items(bellows, manifolds, risers, ujoints). I estimate that it costs $300 more per year to maintain (not fix) a sterndrive versus an outboard, du to the replacement intervals required for manifolds, risers, ujoints and bellows. Will the outboard cost you more or less than $300 in extra fuel and oil? Also, not all boats are large enough for sterndrive power. You really need at least a 19 footer with its size and displacement for a sterndrive to make sense.
