I would think you could expect similar results from the SeaCraft. The Scout 195 is a little larger and heavier but probably as close to the SeaCraft as you will find tested since most modern 19' fiberglass boats are powered with 150ish HP motors. Based on these bulletins the 2.1L Mercury is outperforming the Yamaha F115 in economy and speed. I'm not trying to bash Yamaha, I love mine. Just comparing something that is known to something that is unknown for reference. Different prop & setup are probably a factor in that but still impressive numbers for Mercury. I looked up two reviews with decibel levels and Mercury did well compared with Etec and Yamaha there too. I think the noise one is a little more subjective. Acoustics are complicated because they measure a spectrum of frequencies and some frequencies are more dominate to the human ear than others. A loud purr may beat a softer screech when it comes to the sound you hear in the cockpit at cruise speed.
All in all it looks like a nice offering from Mercury and they are usually a little less $$. I hope they hold up over time! |
This is with the old Yamaha 115 by the way since it is listed as 408lbs. The new Yamaha is close to the Merc in weight, not sure of displacement.
