Full throttle only :cool:
 
All good tips....

My favorite being - Clean your bottom! Many people have no idea that a dirty boat creates more drag - in my experience as much as 25% more fuel used or more. When my boat used to get dirty (before I bought a lift), it would go from a top speed of 48-50 - down to 35-37!!! That loss goes across the whole speed/rpm spectrum. So full throttle to go 35, or for example 3/4 throttle to go 24! It kills your wallet!

This is one of the reasons we don't use our slip anymore. Tired of the fuel consumption, dirty boat and having to bust my arse when cleaning the hull.
 
What have y'all found to be optimal RPMs / speed for fuel efficiency?
 
Yeah on mine we run around 25-27mph but mostly because it is a nice balance between comfort and speed. But no clue if it is the most efficient
 
6grand seems best on both the 195 and the 252.
 
Lol, when we get out, its all about suckin gas and haulin ass!!
 
Boattest.com has the fuel usage charts for most Yamaha models that will show you the speed, RPM and fuel burn with optimal cruise speed.
For my boat, I've found the sweet spot right at 5000-5200rpm for fuel efficiency over longer distances. I've observed 5100rpm at 27mph consuming 9.0gph for 3.0mpg. That's with 3 people, full fuel, 200lbs of gear, and bimini open in my 2020 212s with the 1.8L engines. Wind, current, water conditions, will all affect that of course.
 

The sweet spot is right there at 7.9 - 8 gph… with 3-4 people, an extra 22 gallons of fuel, 160# of trolling motor batteries, a 40-50# trolling motor, and probably another 250# of gear, and a 50# ice chest I was getting right at 3.0 mpg at 3900’ of elevation with OEM impellers.

Same here 25-28 seems to be the sweet spot
