Basically you should have three lines coming from the oil tank. The two that go to the engine stay, and the smaller line needs to be plugged at the tank. You still need about 1-2 quarts of oil in the tank to keep the lower portion of the engine oiled. When you remove the oil pump from the rotary valve cover, you can install a bypass cover on it, or remove the gear from the pump, and reinstall the pump, and not install a bypass cover.
Here is one from a quick youtube search

Lots of threads on this, IMO not a good idea. You'll burn more oil, the ski will smoke more, and foul more plugs, and if you do regular maintenance there it really no upside to going premix. However if you decide to go pre-mix the procedure varies from ski to ski so we will need to know what ski you have. Also some ski's DI's and RFI's you cannot go premix.

Update I have removed the gear from the oil pump now I just need to determine what to do with the two small oil lines that come off of the pump I'm assuming I just block the one coming from the tank that has the filter on it going to the oil pump

The smaller line with the inline filter is the line that would need to be plugged. The two larger lines that feed and return for the bottom end need to stay, and you will need to keep oil in the tank to supply it. Is there currently a problem with the oil injection system? If not, I would leave it alone and not run premix. I have a Polaris that has been converted to premix, it definitely uses a lot more oil than my Seadoos with injection.

The only thing that fails on these is the little 3/32 oil lines from pump to rv cover and contamination. (water, wrong oils causing sludge, etc) IMO drain the oil tank, purge the lines and rv cavity, replace the oil filter, replace small lines, inspect for leaks and call it a day. Double check the oil pump adjustment. I do it twice a year, or whenever I play with the carbs. The oil cable can stretch over time and set the alignment off.
You're wasting your time, I tried to explain the benefits of the oil injection system in an earlier post, and it was ignored.

Take it with a grain of salt Fish, while some of the posts may be rough around the edges and very direct, this forum has some of the most knowledgeable members about Seadoos. They are passionate about there crafts, and always trying to offer the best advice. I am a member of other sites, but always come back to this one when I search for answers. As far as oil injection problems, Seadoo oil pumps seem to outshine all other brands with very few failures. If you are looking at other sites that are dedicated to Polaris or Yamaha, many of them say to bypass the oil injection because failures are very common. That being said, if the oil system on your Seadoo doesn't have a problem, I would clean it up and leave it in place.

Not true. While I agree that these pumps are some of the most rock solid pumps out there they can fail. I switched to premix this year because my pump is failing. When I lost my engine last year due to a lean seize, I thought it was just due to age and maybe a carb issue. I had the carbs rebuilt a second time and also serviced the pump again and put new lines, filter and using correct low ash oil. During break in when I started to read my plugs, I lean seized again. I found that the pump worked well when the rpms varied but at a steady rpm it was sometimes losing suction and providing no oil. Have to believe the internal seals are starting to deteriorate after 20 years. So now I premix and yes it does smoke a little more and I use more oil but I know the engine is getting lubed.
