I have a 97 Challenger 1800 w/ duel 110hp. The left engine runs fine up to 5000rpm, but if I push it the rest of the way up, it will g to 7000 ten cut down to 4500rpm then work back up to 700rpm. Every time it gets back to 7000rpm, its cuts back down to 4500 and slowly goes back to 7000. I took the boat and had both engines serviced and all the carbs cleaned. The engines fire right up and will run great at 5000rpm, it’s just when I push it full throttle. The right engine runs great even the left is having problems.
