UPDATE!!!!!! After hundreds of dollars spent on this motor it’s fixed. The new air box arrived yesterday and we took the boat out today and it runs flawlessly. Reaches full rpm without bogging. Sure would have been nice if the marina would have known that but I guess my son wouldn’t have got it for free if they would have. Thank you Fleetwin and Michael!! I didn’t even have to hear the motor run, the smile on my sons face said it all. He got 18mph on the gps in his 14 ft alumacraft. Thanks again. Dave

We got the motor for free. So I’m not out anything really. I did the water pump, gear oil, carb rebuild, plugs and of course the air box. I always change the pumps when I get them so I know when they have been done. This is a fresh water only motor. My sons father in law gave it to him after the marina charged him $500.00 and didn’t fix it.

His father in law was actually here when we test ran it. He told me I was wasting money on the air box but I had remembered seeing something on here at some point about the importance of the proper air box and knew I would get good advice. We have a copy of the bill and I will post it when we get home. We have a bunch of motors that HAD the 100:1 stickers on them and the first thing we do before going over them is remove it. All of my kids and grandkids have Been instructed as well. I remember buying a new Evinrude 20hp that the dealer was bragging about running on 100:1 and actually told me it would void my warranty if I ran 50:1, I ran 50:1 anyway and it still runs perfectly today.
