    Oil lines for the ultra 150

    okay with some really good luck i inspected my oil lines for the first time. All three of them have about 100 cracks leading to the carbs. There was a small pool of oil by each carb. I was wondering if they made certain oil lines that were better then others. If not then what do yall recommend and where from?

    I just replaced all my lines. Talk to Steve at Skiworx. He has good quality line.
    Be carefull removing the lines at the carbs. Watch so you don't remove the checkball fitting on each carb. ( the barb fitting the line connects to) PM me if you need more detail. Ron

    I replaced the oil lines on my '99 last winter. They were in good condition, no cracks or anything, but I feel better now. I used urethane hose and secured them with stainless safety wire.

    One thing I did find was the cable that hooks to the throttle was badly frayed. Apparently this is a common problem.

    Mine is about toast but I'm on a small enough lake if it goes out I can still make it to shore with ease.

    Take a razor and slice/split the line so it comes off easy. Remember to put the lines back from where they were removed. Also fill the line with injector oil prior to the final connection point. I ran 50:1 premix on the first tank while checking for air bubbles in the lines. Once your satified run with just the oil injection.

    you can block the oil pump off and go premix if you want

    or if you replace them, make sure you bleed them first of fill them as mentioned above.

    Not on an Ultra 150.

    It is well known that the oil pump on an Ultra feeds the counter balance cavities. That oil is then cycled through the crankcase on the front and back cylinders.

    You can premix an Ultra but it is pretty envolved.
