Now that the Kenai is going four stroke or two stroke direct injected 50 hp max I am looking to add a new motor to my bag of tricks. I want to get a jet powered motor with 50 horses at the drive shaft (meaning 35 horse at the jet). I want a light, dependable motor to put on a light riveted 1684 Lowe jon boat. Weight is an issue as I tend to get stuck on sand bars when the migration happens. Which would you prefer - and why? Yamaha 50 four stroke with a jet unit. Evinrude Etec 50 two stroke with a jet unit. Honda 50 four stroke with a jet unit.
