Just completed a week of watersports with no motor problems. My son reported that on the way to the launch ramp the boat suddenly dropped from 43mph (wot) to about 35 mph. He said after that it seemed to surge...rev up and down. The hour was late so I could not do any additional checking. I am going back to the lake in a couple of weeks and am wondering what I should check first. I put 12 gallons of premium fuel in that same day and obtained the fuel from the same station as I always do. I know this isn't much info but would appreciate any help you guys can provide.
