Is my Seadoo dealer trying to screw me?

I just brought my 99 GTX into the dealer for winterization. The thing has
run less than perfect all summer, at least it ran poorly after having it
tuned in the spring. The machine has a definate smell of gas now and seemed
like it was running rich. Now the dealer delivered it in the spring and we
tied it to my dock, a few hours later it was sunk, they had forgot the
plugs, someone came out and floated the rig and cleaned out the engine.
Anyway it seemed OK but never ran very well after that, hard starting when
warm. But ran well most of the time. I did notice about a 3-4mph reduction
in speed this year over last which I attributed to it running rich and the
smell of gas..

OK, so anyway the dealer has the boat for about 1.5 hrs and they call and
tell me the machine has been winterized, they found and plugged a leak on
the fin I had complained about and Oh, by the way you have two scored
pistons.......So I ask first if they did a compression test or a leak down
test, no to both, buy then how the hell do they know the pistons are
scored?!? Is there some magic 10 minute exam that can reveal this that I
know nothing about?!..... I ask how they know as they didn't have time to
remove cylinders or even the heads! They stumble and say errr.... well,
you'll have to ask the mechanic as he wrote it down.

What gives?
