Choosing an outboard

[foolharty]

Have been searching Craigslist and the eBay very intensely over the last week. Restored 20 CC with composites, lighter than original. 50 gallon tank. Will see some trips loaded with lots of people, also can run as fast as my heart desires in an enclosed harbor. Conversely, will do a lot of open water 25 mile trips out to Nantucket. My options/ leads as of now are:

02 Yamaha 115 2s for $2300, looooowwww hours but 20" so would need $600 baymfg extension kit....... Verdict: Rather not

97 Mercury 125 2s for $2700, ~350 hours, 25"......... good option, nice and light

98 Mariner 200!! 2s for ~$3500, 1050 hours, 25" no prop, controls........ 400lbs, "very efficient" according to owner. Will have the power to fly, but can also tone it down to cruise at low stress. Heavily considering this, most likely talk it to $3000.

05 Suzuki df140 4s $4000, 1050 hours too, 25", no controls........... obvious perks of a four stroke, about as big a 4 as weight allows. Probably more reasonable than a 200 with gas and resale considered. Weak 140 horses?

What do you all think? Fuel management is probably the most important consideration. Budget has a bit of heft but by no means want to blow it all... trying to be frugal but will sell it later and want it to be appealing to prospective buyers.
