I have a 30' Chriscraft with twin TAMD 40B's. The last two trips I have experienced a problem where the Port engine looses RPM's. I will be cruising at 3200RPM and the port engine suddenly drops to 2900 or 3000, then after a second or two it slowly climbs back up to 3200. It does this every few minutes. Aside from the loss of power, the engine seems fine, temp holds steady, no change in exhaust smoke.
I changed both the main and secondary fuel filters, but problem is still there. Only happens on the port engine, not starboard.
Any ideas what can cause this?
