1652 Weld-Craft side console W/transom pods for a total length of 17'-11" and 6' width. 2020 Zuke DF60A W/Stainless 3 blade Power Tech 15" prop. Zuke operating range is 5,300-6,300 RPM. Currently getting 10.5-11.5 MPG @ 20-24MPH cruise @ 3,900-4,300 RPM. Top speed is 34 MPH @ 5,400 RPM, 900 RPM lower than Max RPM. This is at 3/4 throttle, the last 1/4 of throttle (around 2.5" of throttle range) does not increase RPM. This tells me I need to reduce pitch to at least a 14" to optimize RPM range. I'm not looking for more top speed, 30MPH is plenty fast enough. I'm looking for better MPG @ cruise. I know with a lower pitch my RPM will increase a little @ cruise speed but in theory I think matching the prop better to the engine will increase efficiency and help overall MPG. Anyone agree of not? Am I chasing my tail and just leave it as is? Thoughts?
