warning alarm

[blake115Yami]

I have a carb'd 115 with oil injection removed.The warning alarm goes off every time I hit a decent wave or boat wake.In flat water everything is fine.It is not a rev alarm because the boat is not leaving the water,just pounding a little.Any ideas?

blake,
The wiring that use to go to the level sensors of the local and remoter oil tanks may be shorting out when you hit a wave - causing a low oil warning.
Or the wiring to the thermoswithces may be shorting - trace the wiring from the switches on back as far as you can to the CDI and look for shorting to the engine block.

Where would the oil level wires be?Also,where are the thermoswitches on the motor?When I find them what can I do to make it stop happening?

blake,
The thermo switches are located in the head assy - one on port and one on starboard side. They are towards the top of the head and are a small round rubber looking thingy about the size of a nickle. They have two wires coming out of them - mine are black and pink (2000 C115). There is a bullet connection for each wire about four inches away. Look there for possible shorting to engine block.
The local tank for that motor I believe is located on the side of the port cylinder assy. I would look for the wire harness there. You are looking for any wire that has been left open and bare with a terminal connector attached - something that could short out to ground (engine block) when the motor is shaken (hit a wave).
The remote tank would have been located down in the bilge area close to the transom. Again look for any wire that has a bare end.
If you find any wire that has been left bare, just put heat shrink on it, or tape it well with electrical tape - something to keep it from shorting out to ground or any adjacent wires.

Loose battery cables can cause an alarm, make sure battery cables are clean and tight and check the 2 inline fuse holders on engine, unplug the fuse and make sure it fits into holder may have squeeze prongs in fuse holder to get a tight fit between fuse and holder.
