Re: 150 hp under powered
 

I am also using a 15x17 ss prop on a 155 commercial evinrude. I get about 38 mph wide open. Is the 15x17 prop used by most of you on a step v 20 ? I was going to try some different prop sizes but I think I'll leave it alone if that's the best torque and speed I'll get. Dennis

I use a 15X15 1/4 I have used the 17 but I like the out of hole better then I like the top speed.
When there is 3 guys and 200+ pounds fish I need that little extra push!
But I stll get up to 38mph with a light load, and curz 30+ with all the weight and thats fine by me ;D

I've never herd of a 155 commercial Johnson what year is the engine. I had trouble matching my vin. number to part # when trying to find a few parts. The place working on my motor said that it was a Military issue and when I asked the difference they had no idea. They thought maybe a little more corrosion protection and gearing than the commercial engine.
