I am thinking the rotary shaft seal failed.
Is there still oil in the two big lines that run to the rotary shaft bath?

Of course, that is being fed by the oil tank so it depends on how much was/is in the tank.
Does it seem that the tank is a lot lower than the last time you looked at it?
At this point, it looks like the only way to find out may be to pull the rotary valve cover and get a look. You could try blocking the feed line to the rotary shaft and let is sit for ever how long it sat before you noticed this issue (unless that was like all winter or something). The feed line is the one that comes off the tank fitting on the bottom. With that blocked, the oil level in both lines would drop if leaking out of the rotary shaft cavity.
I do not see how the oil could have come from the injectors unless perhaps the tank had a LOT of pressure in it from heat. That is assuming it even could push it through the pump.

What is the symptom?
Not running? heavy smoke? No start?
If you premix and open the carbs you will find oil present.
Are you saying the bottom of the motor is full of oil up into the throats of the carbs??

pulled ski out of storage and found oil in bottom of hull and oil in motor all the way up to throat of carbs. I didnt try starting it.\
does the oil tank have an over spill that goes back to crank case of motor?

it looks like oil tank was full and i tillt ski to drain water, maybe causing oil to overspill into crank filling it up all the way to carbs, so far ive drained all oil from carbs and motor I'm going to refill let sit overnight and see what i find.

I do not think it could get through the oil pump like that so the likely leak is either the two seals on the crank for the rotary valve shaft, the seal on the rotary valve shaft itself, or the cases themselves.

Tex it looks like there is a seal that leaked on you, pull plugs, ground plug wire and put rag over plug hole then crank till most oil is gone. Then dump a little gas down carbs and repeat to try and get most oil out case. once that is done it should crank up but be ready for alot of smoke i used a little starter fluid to help mine on the first crank to fire up. was worried about burning up starter hope this helpes

rotary seal is bad,,
you can do as (trollfromthebyu) stated and get it back running,, seal should be replaced soon though.
