Can't find oil leak RXP-260

[andrewthomz77]

I have a 2012 RXP-260. Almost 300 hours on her and nothing but perfection!

Last time I was on the water, every time I let off the throttle, I kept getting the low oil indicator. So, I pulled her out, and checked the oil, only to find out that it was almost bone dry. I do routine checks every time I ride... It was at the correct level before going out, and empty when I got back in.
I ended up putting another quart of oil in her, took it out again, and after 20 minutes of riding.... I got the indicator and checked.... oil was empty again.

I have found forums saying it could be the oil cooler, the drive shaft leaking, or the oil filter.
I replaced the filter, no leaks or issues there... I'm leaning towards the oil cooler but that's a big job to do if its not the thing that is leaking.

Before I rip the machine apart... is there anywhere that you guys can think of that I should be checking for the leak?

Often its the drive line oil seal,,,dumb question,,,is there oil in the hull?,,,if yes,,,great,,,you are in luck.
Or,,it could be rings or valve seals,,,have you checked compression?

If not in hull, seems like you should see it in the lake.

Do any of the spark plugs look like excess oil is getting into power cylinder?

It seems like all the oil is leaking into the hull... haven't seen any oil in the water at all.

Spark plugs came out clean, no oil in there. Just a lot of oil in the hull everytime. Vacuumed it out last time... filled up the shop vac 1/3 of the way.

Putting my 2005 215 back together. Have most of the service manual memorized by now
There is a weep hole on the water pump / oil pump / PTO housing. If the seal between the 2 starts to leak, it will leak either antifreeze or oil depending which side of the seal fails, into the hull.
Not sure if your year is the same but you may want to wipe it down and look for signs of leaking.
