I recently acquired a 2005 Sea-doo 3D, this is my first ever ski and am coming from an automotive background needless to say im sure i'll be in for some excitement.
From what i've learned its a 787 RFI 2 stroke
Before i got the ski it was stored on the trailer with the passenger side wheel taken off the trailer as added security, the oil reservoir was not emptied before storage and with the wheel missing off the trailer the oil tank was a lot higher than the block, when i first got the engine was hydrolocked, i could only get it started by removing the plugs blowing all the oil out then it would actually turn over and try fire. Got new plugs in it still couldn't keep it started unless i was cheating with starter fluid.
Now i'm not helpless here, its pretty obvious this things got a intake fuel pump module and it was not kicking on. So i sourced a entire module from a 04-07 GTI that had the same connector(fuel oulet was clocked differently too had deal with that) and dropped it in. Took a few tries, but now i am getting it to start and stay running. Yes, i keep water running to it while running and kept it running for about 3 mins while it smoked out the neighborhood. Thing hasn't ran in at least 2-3 years according to the previous owner. It smoked ALOT at first but cleared up shortly and each start now has a little less smoke.
This is my first small engine, i come from rotary and boxer engine automotive background. Forgive my ignorance, but there's no oil pan right? Just the engine case and the external oil reservoir, so do i change the oil before attempting my first sea trials? I would assume fine the lowest port on the engine and drain from there, but is there even a point to do that? Should i just suck it from the reservoir add fresh and crank it over and let it ride?
Are people concerned about the oil injection? When i hear oil injection i think of failure points, is it unwise to attempt to block off oil injection and run premix?
Or is the failure rate so low on these its really about just taking care of it.
When it comes to 2 stroke oil, only thing i know currently is "tcw3" rated oil for premixing in my cars, can i use that generic stuff here? Manual says mineral oil, but i just want a 2 stroke oil i can get off the shelf around town.

tl;dr
just got jet ski from crackhead neighbor cause was behind on rent, talking <$500 total investment so far. help me decide if want to flip or keep?
