Jet and am currently having it repaired. They are going to have to tear
down the whole engine to check the internals.
I too called Mercury and they seemed awfully complacent about the whole
thing..strange when you think of what an oil shortage can do to a
2-cycle engine.
I ran it back to the dock while it was intermittently beeping (every 2
mins or so) so am concerned about engine damage.
The oil tank float sensor is a different device than the crank shaft
sensor, so how would cutting the float sensor elimate the beeping for
the crank shaft sensor? By the way, the oil tank sensor can be
unplugged (following the wires) which would do the same thing as cutting
it, wouldn't it? We tried that, and we got a constant beeping. What
you really want to do is to ground the blue wire (I think it is..I
can't check since my boat is in the shop). This will bypass the float
sensor but will do nothing for the crankshaft sensor. I'm not sure how
to get around the crank sensor. If I were you, I would take the painful
approach to the problem: park it until the shop checks it. Like Larry
said, there might be a piece of gear bouncing around in there. Plus, if

there's any engine damage, you might be partially responsible.

P.S. If I were you, in the future I would strongly suggest premixing
some oil in the gas tank to give the engine some extra lubrication which
might help if you encounter another oil injection problem. I learned
that from this newsgroup and am hoping it has saved me a fried engine
