Mariner 60efi 4 stroke Hesitates
I had a cooling problem fixed under warranty, since getting it back from the dealer the motor hesitates badly when coming off the throttle hard then throttling up again. No good at all in rough conditions!! It runs well at constant RPM and the pick up is ok in the upper rev range.
The dealer is unable to create the fault when loading it up on their Dyno, no problems reported on the ECU diagnostics however the fault happens in the real world.
I have tried a new tank of fuel and fuel line and checked for anything obvious. The engine was so smooth before.
I will phone Barrus on tuesday to find out if they are willing to help resolve this issue.
Can you recommend a good Merc / Mariner dealer? I am willing to travel.
