oh ok. I couldn't remember what rpms they ran it I just remember it was low. Never the less it is still very impressive. Our local water taxi has a pair of f90s. They have probably a couple thousand hours. But he runs them poor motors hard. They look like they are a thousand years old. They have been through several gearcases also. He had a running problem so he ran the boat, picking up passengers no less, while I checked out the motor. His driving scared me! I will never go on that thing again. Our Honda 130s that we have on several of our towboat have been very good. A couple are closing in on 3000 hours.
