all the strike master augers can be switched out if you choose too. they come in 5,6,7,8 and 10 inch models. they also made a 9 inch at one time. the new this year strike master lite series of augers is offered in a 6 inch lazer model and a 8 inch chipper model. they both use a 1.5 HP solo motor. the lazer version will run about $379.99 and the chipper version will run around $329.99. they will weigh in about 21 pounds for the lazer model and 24 pounds for the chipper model. this is not the honda 4 stroke thou. the honda is only sold with a 8 or 10 inch auger. okay I just re read our post, I take it your honda came with the 8 inch but you just found the 5 inch power auger to replace your 8 inch. if that is the case then just to let you know they have always had these you just don't hear about them much. Reed's has all sizes for sale in their catalog. I am thinking of ordering a 6 inch for my auger.
