Yamaha Top Speed

Phill asked on 3/5/2019 10:52:43 AM
I have a 2011 Yamaha 40LA on a pontoon boat. Runs and starts fine. My issue is the maximum RPM is 300 rpm higher in cold water than the summer. Every spring and fall the engine and boat speed is higher. 4700 rpm cold water and 4400 Rpm during the whole summer season. Is there a faulty temperature sensor? Possible adjustment somewhere?
Any help would be appreciated.
Phill
