Hi Gang
I have a twin engine inboard Pursuit I am working on. The motors are 2008 5.7 fwc TBI with dry joint exhausts and a serpentine belt setup. These are Mercruiser replacement motors. They idle and run smoothly.
After 5-7 minutes of running both motors at 3200 rpms, the port engine hiccups, bogs and drops down to 2500 rpm. If I return the throttle lever to neutral and accelerate up to 3200 once again the problem re occurs after 5-7 minutes of operation like clockwork.
I can cruise all day at 2800 rpm on both motors and all is fine.
The fuel vents are clear and the fuel filters are new. Any ideas?
Thanks in advance
