Often times, when pulling someone on a tube and starting from a stop, the alarm will go off...I can back off the throttle, then throttle back up and it will stop. Any ideas what this is?

I thought the oil level was low, topped it off, but it still does it.
 
You don't say what drive you have, so I am only guessing. But our boat has a drive lube reservoir at the front of the engine. When that is low, I get an alarm like you are talking about.
 
The reservoir at the front of my engine has been topped off and is ok. I also have another small reservoir of some sort in one of those rear side compartments...I don't even know what that is. I guess I need to figure that out.
 
Any water in the bilge?

Do you happen to have 2 bilge pumps..... one for normal level and a 2nd for high water level .... most of which is always alarmed.
 
No water in bilge. Only one bilge pump.

A little research and it looks like the other unit in the bilge is the trim pump...Maybe I need to check the level in it? Does it have a sensor/alarm?
 
I do believe that there are only 3 reasons for the alarm to sound. Low engine oil pressure, over heating and low oil in the lower unit reservoir. If your gauges indicate that there is not a problem with the temp or oil then i would concentrate on the lower unit oil reservoir. If the oil is full and not over filled then poke around in the container. There is a float switch in there that may be stuck or gummed up. I'm betting this is your issue. And yes....that's your trim pump. No sensor there.
 
The three reasons for the alarm are low sea water pressure, meaning your impellor pumping water out of the lake to cool the engine, actual high engine temp, and the drive lube reservoir is low.
Unplug either of the two wires going into the reservoir, and see if the alarm goes away.
