Beau - the key thing which stands out to me in your question is "long range" cruising. If by that you mean getting off the beaten trach and into the international boondocks, then Yamaha 2-stroke is the ONLY way to go. I keep my boat in the southern Caribbean
and the ONLY motor
you see on the boats of local fishermen as well as on 90% of cruiser's dinghies are Yamahas. Why? Because the Endoro series are simply, they run forever and because parts
are available all over the world. By the same token, those who cruise
the world say pretty much the same thing. If you plan to spend most of your time in the states or in highly civilized places with plenty of marinas
and techies to work on your equipment
then go for a 4-stroke with EFI; they are more efficient and pollute less. BUT, if you want long term reliability
, simplicity and availability of parts, then by all means go Yamaha 2-stroke.
BTW - mine is a 2002 15 horse on the back of a 10.5 foot AB aluminum
which I use with my charter
boat. I have no idea how many hours are on it at this point, but it is a lot
. It has been flawless! I probably should change the spark plugs on of these days .....
PS - one of the big bareboat charter
outfits are using Tohatsu's - but I also see many of their clients having trouble getting them started: FWIW.
