Is there a friction control on the Quicksilver Throttle control has the trim , Trailer, and Fast Idle (disengages the gear box cable) Any thing above about 2/3 throttle it backs off
I am having exactly the same problem with my throttle on a 1978 Merc 900. Dealer told me its a safety feature. Hard to believe that losing control at 35 mph any worse than 25 mph.
