    Suzuki DF60A Throttle body.. Is this fully open when in WOT???

    Unfortunately, I live on an small island and don't have a lot of options. I bought the boat from a manufacturer and bundled the engine based on their HP specs. I wanted a Yamaha 60hp because we have a dealership here, however at that time they didn't have any available. I went with a Suzuki with...

    Suzuki DF60A Throttle body.. Is this fully open when in WOT???

    I don't mind loosing a couple of mph at top end, if I can get the boat on plane easier at lower rpm. Maybe a smaller diameter and 11 pitch prop might work better for my case when switching to 4 blades....

    Suzuki DF60A Throttle body.. Is this fully open when in WOT???

    Yeah, that's what I was thought as well. In theory anywhere between 300-400RPM. Here's a performance test from Suzuki DF60A on Caravelle boat that weights over 1500lbs, with a bigger pitch 15. This is confusing as my boat weighs about the same loaded on a 14 pitch and struggles to get on...

    Suzuki DF60A Throttle body.. Is this fully open when in WOT???

    Yes i absolutely agree. I ordered a Solas 11.6x12 to see if there’s an improvement.. I’m also looking at getting a 4 prop to test, heard they plane easier and lift the stern.

    Suzuki DF60A Throttle body.. Is this fully open when in WOT???

    I can get to about 6000 rpm alone, but this was a run I did once. most I got on two person with gears and half tank of gas is 5300-5500 at a speed of 20-23 MPH. 4 people no gear, just cooler with drinks, ice and some food, it will not hit 5000.

    Suzuki DF60A Throttle body.. Is this fully open when in WOT???

    It was rated for 40-60hp. The prop size is an 11.6x14 and trim set all the way down and slowly move up as I pick up speed. The boat can plane when I'm alone or after a long day fishing with another person when most of the gas and ice melted. Top end speed with two person as in low 20's.

    Suzuki DF60A Throttle body.. Is this fully open when in WOT???

    It was pretty much the same, no change just worked with what I had. A mechanic suggested to try and adjust the mounting hole as it was originally sitting a bit low below the transom from the factory. Another suggestion was a prop with a lower pitch. I'll be testing the prop soon when it arrives.

    Suzuki DF60A Throttle body.. Is this fully open when in WOT???

    Yes I agree, boat feels sluggish. I'm not sure if the butterfly is fully open, as I am just inspecting visually from what I can see. Based on position of throttle body on WOT, there is still some leeway for the butterfly to swing a bit more. Just wondering if someone who has a suzuki motor can...

    Suzuki DF60A Throttle body.. Is this fully open when in WOT???

    I have Suzuki DF60A 2022 on 17ft fiberglass fishing boat which weighs around 1,100 that struggles to get on plane with full tank of gas (20 Gallons), a cooler with ice, and two adults weighing close to 200lbs each. I have adjusted the engine mounting two holes up with a slight improvement...
