I have a 2000 V4 115 Yamaha on a 16ft skeeter The manual says the WOT operating range is 4500-5500. This is a broad range and seems to be quite low (anything under 5000). WIth my boat empty, in cool conditions I am getting 6000 RPMs. SHould I back off a little in these conditions? Im not running like that for very long/far though so am I ok running it at 6000?
IMO: The more the merrier!
Thats what I was thinking (to some degree). Anything under 5000 is lugging that motor and most other motors. The 130 V4 Yamaha was rated 5500-6000 and they are pretty much identical engines, so...
Eleven year old motor ... keep it down at 5500...no sense testing this older engine above mfg specs....and I'll bet the increased speed is minor.
If it blows you'll regret it.

My friend gives me a hard time because even though my yamaha is 11 years old, it probably has fewer hours on it than a 2009 model! All I need is some weight in the boat and I wont "red-line". Thanks

Yessir, she is propped good. Had mark B&B, clean and add cup to my pro series prop 5 years ago. Those last few hundred RPMs sure does lift and add a few MPH
