I’ve owned them both.
The first time you run the 2.5 you’ll think you’re cutting with the most impressive ice auger ever made. IF there was no 3 HP version you would NEVER feel like you needed anything more.
And then you pull the throttle on the 3 HP version for the first time… simply amazing!
If you regularly fish on thick ice (25″ – 30″ PLUS) and you’re one of those guys that punches dozens upon dozens of holes in a day… the 3 HP is worth the extra $$.
IF you punch 10 holes a day or you don’t run into 30″+ ice very often… the 2.5 will do more than you’ll ever ask of it.
Either way you’re getting an auger that is in a whole new class when compared to the Tecumseh powered versions that were retired two winters ago. If those Tecumseh powered augers represent your last hands on experience with a Strikemaster… you’re in for an eye opener the first time you hit the throttle.
