    counterbalancer oil

    on the 787, how often does one need to check the oil level in the counterbalance? and how much oil to put in? how do you tell if it needs oil?

    every season.Take a wide flathead screwdriver and remove the cap and should see the oil close to the top and i used synthetic oil to top it off.Thats good that your checking that,ive seen alot of failures from this and theres no mention of it even in the SHOP manual as i remember.

    You are showing your ignorance now sea-one.

    The c/b shaft oil never needs changing on a 787 engine, as it's open to the cases. It constantly exchanges with the fuel/oil mixture that runs through the cases of the rear cylinder.

    You only add 3 ounces of whatever two stroke oil you intend to use when you build the engine. Thereafter, it is a constant mix of fuel/oil.

    have to agree being an ex employee of a seadoo dealer, and having rebuilt a bunch of engines, the 787 doesnt work the same as the 951 with a oil rev. for the CB shaft.

    +1. Also FYI, I believe the Seadoo shop manual says to use SAE 30 which is WRONG for the 787 engine. Just use two stroke oil.

    I have always wondered why Rotax put in a fill plug starting in 1997 on the 787? Drain plug I can see, as it is the lowest part of the engine if it ever gets water in the cases, but fill plug?
