My motor tops out at about 5800 rpms. It's a 4-stroke 115 Yammy. I've always followed the conventional wisdom of not approaching the top rpm's when I'm running from spot to spot. Typically, I'll run at about 4600 to 4800- it's plenty fast and I assumed used less fuel. However, I've heard recently that this isn't necessarily true. Is it true that 4-strokes will get better fuel efficiency and be easier on the motor when they're run at higher rpms (like 5300 to 5500)? For the life and health of my motor, what's the ideal rpms to run it at? For fuel efficiency, what's the ideal rpms to run it at? If these aren't the same, what's the ideal compromise to run it at?

We're usually fully stocked but you caught me on a bad night!
Tuesday night is usually "board meeting" night if you know what I mean. Stop in and have a tasty beverage some Tuesday night after these holidays are over and things get back to normal.
Im sure I will be back soon my kids go through the pork burgers pretty quick. Suzy knows who I am she can help ya. Cant ever turn down a nice cold Busch Light.
