when i made my approach to the dock i lowered to an idle and shifted into reverse to bring her to a stop. it then started to chug and would not raise rpms to even idle, i shifted into neutral and worked the throttle in vain as the dock grew ever closer and my jetski looking ever more fragile. luckley my friend was able to jump to the dock and muscle her to a stop bur this is a growing problem does anyone have any ideas as to what this could be. is there any way the batteries could be over taxing the alternator and putting too much load on it at low speeds? or maybe a carb problem?

Others might be able to help with a bit more info. I suggest putting your boat information including engine (s) and drive in your signature.
Sounds to me like an adjustment issue on your shift cable. Your shift interupter is coming on causing the engine to stumble (which it is supposed to do when shifting) but it is not coming off when you give it more throtle.

Its most likely the OMC ESA shift interrupt switch. When its working, its what makes the engine stumble when you shift out of gear.
You may need a lower shift cable and an ESA switch replacement, plus a fresh adjustment.
Remember that your gear selection changes must be made quickly and decisively...... don't fool around with slow shifts.

More likely a sticky lower transom cable is keeping the ESA engaged when you are in reverse gear. That is only supposed to engage in the split second that it takes the drive to drop out of gear. Because you are coasting in neutral, but moving forward, there is a lot of load on the prop so the ESA most certainly is needed to get it into neutral.

There will be both a ignition interrupt and an over-stroke micro switch in the system.
