2007 VP 5.7 Gi Throttle 'hold-at-speed' issue. Four Winn Horizon 220

[Tydog96]

I have a throttle question.

The Throttle will not hold 'at speed'. Example, set at 30 mph and very soon it has slowed down to 25 mph - even in calm water. You can't stand in the boat by the wheel at running speed without having to constantly go to the throttle to speed the boat back up. aggravating. Is there a tension adjustment anywhere in the throttle linkage or assembly? I've not yet pulled the flame breather off the engine manifold to see what that linkage looks like.

Ideas? Thanks.

The control may have a tension adjustment. But you told us everything except what control you have.

Moving into the Steering and Controls section.
