oil leak

[Paul Herder]

does anybody know what the three oil lines coming out of oil reservoir tank are for, one looks like it goes to oil pump and carburetor. is one a return
line ? this is on a seadoo speedsterSK with Rotax 717

The one to your oil pump is the oil injection, remember it’s a 2-stroke so it burns oil with the gas.

The two other lines are for the rotary gear oil bath. It doesn’t circulate it is just a cavity in the block to lube a right angle gear for the rotary valve.

Make sure you are only using API-TC oil, never anything that says TCW-3.

Thanks for come back. that must fill up that cavity, that thurd line must be return since it goes
to the top of tank
