1990 Seadoo SP Oil Leak
Is there a common place that these leak oil from the front of the machine?
I'm wondering if they have a habit of cracking the reservoirs, or a good place to start looking..
I havent been able to see anything obvious.
Can I just ignore the oil injection and just run it premix without any issues? (just oil in the gas, and not cap anything off..let oil system dry out)

you can but it will ruin the oil pump if it runs dry unless you get a block off plate and remove the oil pump driveshaft behind the front housing

The rotary gear chamber must have an oil supply on a Rotax. I would check at the bottom grommet of the oil tank, and also the tank seam itself. If it were mine I would loop the large oil lines together with an elbow and make sure they are full. Pull the oil pump off and install a blockoff plate. You can also just remove the pump drive from inside the intake, then leave oil pump and lines intact. Then start running 40:1 pre-mix.
