Boat will only accelerate...

Boat will only accelerate if I push the throttle back and forth

Mechanic's Assistant: Sometimes boat issues seem like they'll be really complicated, but end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so the Marine Mechanic can help you best.

It is a 2001 Mercury EFI offshore 250 runs like it is in limp mode unless I push the throttle back and forth then it will accelerate to about half throttle but if I stop pushing the throttle it goes back down like it is in limp mode

Mechanic's Assistant: Is there anything else the Marine Mechanic should be aware of?

Not that I know of
