I need some help here. I have a 1985 sear ray sundancer with twin 190 mercruiser motors. Recently the port side motor has been giving me some issues when running on longer trips. (12 miles out or so). I seem to be loosing some rpms and bogging down and then when I try to give some more throttle she Boggs even more. I have had the carb rebuilt,full tune up, and coil replaced and it has not fixed the problem. Any suggestions would be very helpful. Thank you.
