My recommendation, as always, is to put maximum rated power on the transom. In view of this here's what I recommend:In the most bang for the buck category:
1st Choice: Johnson 150 because its torqy, fast, cheap (under $10k list price), simple technology (carb'd induction), lightest (375lbs).
2nd Choice: Either (a) Yamaha 150 because its cheap (under $10k list price), simple technology (carb'd induction), Yamaha's reliable reputation, or (b) Mercury 150 SW because its the cheapest (under $9k list price), simple technology (carb'd induction). I lean towards Yamaha because of general reliability reputation and personal experience with one.
In the environmentally friendly 2-stroke category:
1st Choice: Evinrude 150 Ficht because of the low end torque, lightest weight of all DFIs, and belief that Ficht problems on the 150s have been overcome.
2nd Choice: Yamaha 150 HPDI because of Yamahas reputation (can't give it a first choice rating because this engine is a beast at 466 lbs.)
3rd Choice: Mercury 150 Optimax due to the general Optimax product and service reputation, which is in need of improvement in my opinion.
In the 4-stroke category:
Only choice: Suzuki DF 140 4-stroke because it is light weight. Honda 130 is more expensive, needs EFI and needs to go on a diet in my opinion.
In the twins category:
I'm torn between the Merc 75 Classic (generous displacement, but heavy at 305 lbs) and the Yamaha 70 (small displacement, but light weight at 228 lbs). While it is true that the Outrage 18 was designed for twins, I don't think it was designed for twins that weigh over 300lbs each. So the Merc 75 Classic is really pushing the transom weight limit in my opinion. On the other hand, I wonder whether one of the two small displacement Yamaha 70s would be capable of of getting the Outrage on a plane.
No 4-strokes make the twins grade because they weigh too much and cost too much.
Overall: If it were my 18 Outrage, the Johnson 150 would get the job.
