I have a 2001 310 Sundancer with twin 350 Horizons and V-drives. While prepping the boat for launching today, I noticed that the starboard throttle was at about 1/2 speed. When I pulled the handle back to the idle position I noticed that there was virtually no tension on the handle when moving it between the 1/2 throttle and the idle position. After checking further, I discovered that from 1/2 throttle to full throttle there is far more tension than there should be. I had no problem with the throttle when the boat was hauled last season, but I did have some work done on the engine a few weeks ago. The port throttle is fine. I’ve seen some posts about stiff shifters or throttles, but none about a handle that was too loose on the low end and too tight on the high end. Has anyone experienced this and determined the cause?
