A few years ago I was representing for Pacific / Black Lab boats, manufacturers of welded plate alloy boats.
The demo boat we had at the time was a 23' center console that wore a 250 Suzuki (with a 30" shaft).
One of the boats I sold went to a local rescue squad and wore a 250 Evinrude, so I had the opportunity to run a pair of nearly identical boats, with Suzuki and Evinrude power.
Seat of the pants impression?
Both motors returned good performance, but the Suzuki was absolutely the louder of the two. Airbox noise maybe?
Not sure why, but at cruise the Evinrude was noticeably quieter.
The Evinrude was also quicker out of the hole and onto plane.
Don't get me wrong, the Suzuki was no slouch, but with a direct comparison possible, the Evinrude got my vote.
Wasn't too sure when the rescue squad chose the E-Tec, but they had local service for it, so that was a big factor for them.
I have to say that when I did our on-water delivery training, the 'Rude made a believer out of me.
