So I'm having this ongoing problem with my 97' Challenger single. NOT cavitation. Boat bites fine. No over revving. As I start to advance the throttle everything comes up fine...to a point. Then It plows water at around 4K for 5 to 15 seconds before it jumps up and makes full throttle. This doesn't happen every time. I almost think the problem is more frequent with a heavier load and/or when warm. Making some quick erratic movements on the throttle seems to help. It never misses and runs smoothly. Once on plane, everything is great. It goes down to slow cruise and back to WOT without a problem. Throttle response is fine.
My current WOT is around 6500 with an average load. Engine has 40 hours since rebuild and 145 PSI on each side this spring. Running XPS and midgrade fuel. Tickling the choke during this condition causes the engine to puke out. Switching to RES line does nothing.
Been told to start with a RAVE service which I will do this week. Been told to change out the plugs, too. Other than that, I'd like to pinpoint my efforts a little. Ive never really heard of filters being a problem on these boats. Maybe carbs? What to you think.
