Question: what rpm should i run my outboard?
Answer: For older two-stroke motors the WOT range is typically 4500 to 5500 rpm. On newer four-strokes and direct-injected two-strokes, the range is often at higher rpm and is narrower, 800 to 600 rpm rather than 1000 rpm. Ideally, you'll prop for an rpm right in the middle to upper part of that range.
