While I'm sure they wouldnt hesitate to run more power, I've never heard any of them claim they were underpowered. I run an 83 115 tower of power ande it does about 36 and gets on plane instantly. My only complaint is fuel economy at hull speed.
The new merc sounds excellent in weight to horsepower ratio. Its only 20 to 30 lbs heavier than the etec and zuke with more ci and ponies. I like 2 strokes, especially modern direct-injects, but I cant argue with a 4 stroke that has cut considerable fat...did they leave out any parts 
Another thing about the merc is that your controls probably swap right in. |
From my readings, they went with a simple SOHC design in place of a DOHC. This accounts for a good chunk of the weight savings. Simpler is better imo
