I just purchased a boat with a '91 200 hp Johnson.

I go to start the engine and it fires up, but starts to smoke
REAL bad. Clouds of white/blue smoke and oily water pouring out of the
hub. It will not idle, but will run above 1200 rpms. So much smoke
that the cloud of oil takes 5 minutes to clear the house, yikes!! I
did reading in the Seloc manual and figure that I have some air leaks
in the fuel line.


Get rid of the NGK plugs and use the Champion QL77JC4 gapped at .030" for
best results. Check the cylinderheads to make sure the motor is coming up to
temperature at idle to about 140 degrees or so. If not, change the
thermostats and check the rest of the cooling system.

From your description, it sounds like you have a leaky oil outlet check
valve inside the "VRO" pump. The only fix, if that is the case, is to
replace the pump. The latest ones, 1998 and later, are completely repairable
and rebuildable, and are simpler inside. For more information on the "VRO"
and troubleshooting, go to:
