Re: Noise level of Johnson 60 vs Johnson 90
Noise to noise sensitive people is less about loudness than it is about the "type" of noise. In reality, four stroke outboards and two stroke outboards at wide open throttle are not very far apart if you look at the noise levels (dB levvel). But because 4-strokes make a different sound (they sound less busy) than a 2-stroke you might say they are quieter when in fact they are very little quieter. So I suspect that the 90, because it is a four cylinder will be smoother and will make a "different" sound, she will likely prefer the 90 over the 60 although she may not actually "like" either one. Years ago my neighbors wife would not allow her husband to run their boat at more than half throttle because she didn't like the noise. I had a 19 ft Century with a 351 Ford at the time which was a much quieter rig than their outboard. Because the noise was different, she didn't have a clue when I was running faster than half throttle.
