Hi all, I'm a new Suzuki owner and need some help diagnosing what I feel is a problem. My dealer doesn't seem to be much help as they don't think there is anything wrong.
The boat is a 2018 Robalo R200 with a 2018 DF140A. The boat struggles to get on a plane and has no top end. After a few test runs these were my results.-----------> R200 Suzuki DF140A.pdf
This is the same boat with Yamaha engines----------> R200 Yamaha F150XA.pdf R200 Yamaha F115XA.pdf (only comparisons I could find for this exact boat).
The big difference I have found with my boat compared to any other DF140A tests I have read is that my fuel flow rate is 8.5 GPH at WOT compared to 12 GPH +/- for every other DF140A in the world.
I dropped the boat off at the dealer Monday morning and explained the issues to them, suggesting throttle linkage or a restriction in a fuel line. I do not believe this is a prop pitch issue, since it doesn't get out of the hole or have any top end MPH. It is more of a lack of power. Fuel flow is in line with a DF90A, and it feels like power is too.
I stopped by the dealer again this afternoon and was told that the throttle was barely out of adjustment, "not enough to make a difference" were the exact words. The service manager told me the tech took it out and the boat planed in 6 seconds and topped out at 6,300 RPM's @ 9 GPH. They couldn't tell me what speed they achieved, as "RPM is all that matters". According to them there is nothing wrong and the fuel flow rate isn't an issue, because they got it to 6,300 RPM. My guess is they had the motor trimmed high enough to get the prop out of the water.
I'm going back tomorrow morning to put it in the water with the tech from the dealership, but I think I'll be left figuring this out on my own. This is where I could use some help from someone familiar with Suzukis. Is my assumption correct, that I cannot be achieving full power while only burning 8.5 GPH? Can anyone with a DF140A let me know their fuel flow at WOT?
Any help would be appreciated!
