This is the first time I have owned a Yamaha. I have a 2006 150 4 stroke. While riding around the other day I noticed that as soon as I let go of the throttle it wouldn’t stay put. It would start easing its way back towards neutral. I have owned mercruisers, mercury outboards, and even a Volvo penta that never did that. Is this normal for a Yamaha or do I need to adjust something. It runs great, but I am just curious about the throttle. Thanks!

If it is a 704 Binnacle, here you go:
Step 1: Remove the 4 screws holding the black cover down. This is true for a single control as well as dual controls. Two on the front and two are aft. Some of you saltwater guys may have a hard time getting these off from corrosion. Try tightening them first, then loosen. Work them back and forth since they snap easily.*Make sure you anti-seize or grease them when installing.
Step 2:* There are four small dimple type pins Yamaha uses as a secondary cover holding method. Getting the cover to pop up is the hardest part of the hole procedure. You can kind of see them in this picture and there are four of them:
You will need to pry the cover off of them. Dont try pushing the dimple’s*in as it does nothing. The cover must be pryed off. You can also try putting some masking tape down if you have a painted helm to protect it from the prying device:
Step 3:* The cover can now be lifted off forward to expose the adjustment screws. Turn them in(clockwise) to apply more friction to hold the handles from slipping back. Go out to make them move easier. Do not try to put it into gear when testing if the engine is not running. Push the nuetral button in on the side of the handle*to move the throttle handle forward for checking. Sometimes I will go out and run the boat to make sure its the correct friction setting before putting it back together.
Step 4: After you are done adjusting, install the cover and push down until you hear the dimples snap back in place. Put some lube on the screws and tighten them. Pretty simple. The hardest part of the hole job is getting the screws out if they are corroded and prying up the cover up*without screwing up the gelcoat or paint on your helm.
