Slack in shifter

[Crab Island Cruiser]

I noticed yesterday that my F115 Yami 4 stroke wouldn't get over 4600 rpm. There is a lot of slop in the shifter. Where is the best place adjust that slop? I'm not finding any good help on the net.

Sounds more like a failure of some sort rather than an adjustment (although I wouldn't rule it out). If it was originally working properly, then something came loose or broke. I'm guessing you will find it at the motor end.
1. Check each end of your cable housing (sheathing) first. You likely will have to carefully take the lid off your control box to do this. There are several ways that cable housings are attached, but you should be able to spot if something broke or came loose. Have someone move your throttle lever while watching the cable housing mount point at each end. There should be LITTLE OR NO movement in your housing. If you don't see anything wrong proceed to...
2. Inspect the cable ends where they attach to the throttle lever (forward) and throttle mount (engine). Make sure they have no slop or broken parts. Put the lid back on your control box.
3. Check for kinks. Disconnect your cable at the motor end (throttle mount). Move the throttle lever back and forth. The cable should move extremely smoothly with little or no resistance. Hook the cable back up at the motor.
4. Verify your control 'box'. In neutral, the throttle at the motor should be at idle. In EITHER forward or reverse, the throttle plate at the motor should begin to open. If this is not happening, there is a mechanical problem with your control box.

Good luck. I would put money on either the cable itself or one of the cable mounts in some way. But I have been known to be wrong, so don't take any of this as gospel.

Take off your cowling. Put throttle at wide open. Take off cable and see if there is any more motion that the linkage can advance.

I don't normally like to argue with guys on a forum, but in this case I might have to call you out on this one. If you 'set' the cable for WOT, you likely will lose your idle setting. Most motors, you set (adjust) the cable for idle, then WOT is limited by the length of the cable (or the throttle stop). Ya'll can beat me if I'm wrong. It wouldn't be the first time

I didn't say anything about adjusting the cable. I can pull one clip and my cable end slides off the linkage. This is just to see if there is more throw available in the linkage. If there is, then you have to investigate why the remote control isn't giving full throw.

Gotcha. I think we are on the same page here. Something came apart or unscrewed.

My guesstimate on slop in this instance may be the fact the OP doesn't realize just how much shifter movement is involved locking the lower unit into forward or reverse before he actually detects the engine rpm's picking up.

Since the shifter and the throttle are 2 different cables, it doesn't matter how much throw is done by the shift itself.

Most shifters have different holes for where the cables attach. If the throttle cable was in the wrong hole at the shifter, you could have less throw.

If the boat used to work well and this is something new that is happening, highly unlikely that the throw all of sudden got less unless something broke inside the shifter.
