When I received it, it was so small that I thought it was a toy, or maybe for some 4cyl engine. It is significantly smaller than the original one. When I looked closer, the mount holes did line up, so I tried it. I did have to get shorter mount bolts. To my surprise, it works great! I don't know what the longevity will be, but it made it through a busy august! Considering the price and how small it is, I might just buy a second one to keep on board. Just in case.
