[QUOTE="scoobeb, post: 438600, member: 6843"] The mercosil powerhead is more prone to blowing according to research so while most of the engines are near identical there is some differences. If you put a 93 and say 95 side by side there is some different components under the cowling. I've never had another merc with the power of this one and it was actually a 20hp and I put a new 25hp carb on it. The last merc 25hp I had on my alumacraft with the same weight pushed me 30ish with a 14 pitch prop, the 93 like I said pushed me 33-34mph. This motor just created so much more power and I don't know why. 1 out of 20 possessed this extra power but they were all great running engines. I love the 25hp 2 stroke yamahas a great deal but my merc ate them for lunch. [/QUOTE]
