I recently had to have one of my shift cables replaced and then adjusted as the shift levers were not aligned after the replacement. Now, after the mechanic completed that task, it seems my boat will not reach full power.
When I throttle up to go on plane, my engines are only reaching about 3300 rpm. (full throttle should be about 5400) if I throttle back to about the 3/4 position, the rpms stay the same, there is no change in rpms from 3/4 throttle to full throttle and the engines do not sound any different either. I also noticed that according to the sync meter, the port side engine is running faster then the starboard engine, from the 3/4 thru the full throttle position, the engines are in sync up until the 3/4 position.
I am assuming this is a simple cable adjustment issue, at least I hope it is. Prior to the shift cable being replaced. I did not notice this problem.
How do I correct this, do I adjust the throttle cables at the helm in the throttle control box or back at the engine?
