"I have a 98 Silverton 352 motor yacht with 454 tpi crusader's. when motors are started after a few minutes they will drop rpm's almost stall then pick up again run for a minute or so then repeat the same thing. So far I have cleaned the screws for the ign module, replaced fuel filters, replaced both IAC motors, cleaned oberg filters,disconnected the orange slave wire connecting the motors, and added new fuel and conditioner to both tanks. The condition does not happen above 1000 rpm's. The boat runs fine at cruising rpm's and even WOT. I also have a definate hesitation on the throttles when in idle and attemting to get the boat on plane. The hesitation only occurs for a second then the motors respond."
