My 2016 Suzuki df30a wont idle and wont run above 3k rpm at around 2500-3k the boat sounds perfectly smooth (7 mph speed). I drained the fuel water separator and it was full of a clear white sand like sediment, I replaced the separator filter and inline fuel filter. I also notice the motor gets extremely hot but pees a solid fast stream of water.
I also pulled the spark plugs and noticed a lot of black carbon build up and they were just changed in January. My fuel consumption was also really bad when I traveled home 8 miles at 2500 rpms.
I tried emptying the tank and putting fresh new gas with some seafoam with no luck.
Should I try cleaning the fuel injector next or what do you guys recommend?
