oil consumption yellow seadoo motor

[pudd750]

i now understand i guess that if the rotary seal in the yellow seadoo engine is bad a oil pump removal wont help- the oil tank remains for lubing the valve ? i went thru oh 1-2 quarts of oil in 2 hours- good spark kept it running - at 1st i was hoping the premix would lube the valve but this is not the case?

It lubes the valve's drive gear on the crank.

Are you saying you are consuming that much oil after removing the pump?
You'd think it would even be leaking down while not running if its that bad..

Re: oil consumption yellow seadoo motor

i havent removed the pump yet but i was stranded in the muskegon river without a plug wrench to blow some of the excess oil out of the case - with both plugs removed - watta day wow -- ive installed inline shutoff valves in the oil lines feeding the pump & bath -- my dealer says twc -3 is light enough to not worry about cavitating the pump --shutoff valves are ok - im now pretty sure i only need the one valve inline to the bath - very bad internal seal- on another note a usual upgrade from the short electrode B8ES is going to a BP8ES --little longer to get the kernel lit a little better? anyone running the "P" NGK plugs in their sleds? sorry - pwcs?

BOTH those plugs are wrong - you need BR8ES, no others.

Re: oil consumption yellow seadoo motor

ah thank you - the "R" being a little extra load for the spark system to equate to a little hotter spark when it does let go?

It's a resistor plug to make the CDI ignition happy.

Re: oil consumption yellow seadoo motor

ok i put it in lake lansing (michigan) today - for a few minutes- till it was obvious the bath oil is invading the crankcase too much to run- nursed it to shore feathering the choke- brought it home- the drive train is now on the bench - jettisoned the oil pump - block plate is due here within days does the mag box interfere with the removal of the lower end cap? hope not - does the crank need to be removed to service the bath seals?
