Over the weekend we were running my 25 ZX in a Poker Run. For some reason when I was at WOT, the rpm would occasionally drop from around 4600rpm down to 4000rpm and then after a while it would pick back up slowly. I could feel the boat slow down when this would happen, so I know its not a gauge issue. This boat with this prop usually runs right around 5000rpm with that prop which is also strange. I did have some cup added to the prop, but that would not have slowed me down I don't think? The boat was also running about 4-6 gps mph slower than usuall as well.
I could have been over trimming it because I need to replace the trim senders and I am trimming based on the feel, but if I was over trimming it would have raised the rpm I would think? Does this sound like it could be a fuel or fuel filter issue? I was running fresh non-ethanol fuel so I don't think it would be the fuel, but possibly the filter? All my other gauges were reading normal.
Any thoughts?
