Water mixed with the oil ?
 

I just purchased a 2000 34' PQ viper with HP500 efi's. the starboard engine has a coating on the oil filler tube that looks like white lithium grease I know that this has to be water mixing with the oil. My questions is how bad is this ? the motor ran just great on the flushing unit. looking into the valve cover thru the oil filler hole everything looked good,no white oil,no rusted springs, nothing. The oil was a shade lighter than the oil in the port engine. Anybody got any experiences with this problem ?

Yup. Possibly condensation. It's worth a closer examination though.

When you say the oil was a shade lighter do you mean "cleaner" this would make me a little suspect of a pre existing condition being covered up. Maybe I am a bit cynical but you get that way working around boats most of your life.

If this engine has a pcv valve make sure it is working correctly. Also make sure the oil temp is getting above 212F.

Probably simple condensation, normal.

CHECK the oil level, is it high?

Is it milky?

Oil level can vary when the boat's not floating, so if it's high by a quart....no worries.

If the answer to both are NO then you probably have no problems.
Change the oil and wipe off what you see and it might not be back.
