High oil level?

[nelbird]

Hello, I changed the oil and filter on my 89 ski nautique this weekend. I let it drain for about two hours before I put the new oil in. I put in five quarts but the oil level is very high on my dip stick. Do I need to drain some of the new oil? I let the boat run for about five minets after I changed it I hope this didn't hert anything.

Thanks

RE: High oil level?

Drain some oil. You don't want excess oil. I don't have the "why" on this, just the experience that every auto or boat forum I belong to says to NEVER overfill the oil in a motor. I'm sure many engines act differently but I know in my old Porsche, an overfill means it is going to smoke like crazy until it can burn off all the excess thus fouling plugs, etc in the process. Hopefully someone will provide the why better than me. Just isn't worth the risk of damage if you ask me.

Too much oil will hit the crankshaft everytime it spins around. That means that for every revolution you wil slap the oil eight times. This slapping the oil causes little bubbles to form. Soon the oil is all foamy, and then the oil pump can not eficiently pump the oil, thus starving the bearings and leaving little or no protection between the two metal parts. Then the parts contact and gouge a large scratch, and then the metal that was gouged out starts to float around the engine, and scratch more parts. Soon the engine either smokes really bad, or worse yet it just locks up from the metal parts welding together.

Don't overfill the oil.

Ditto every word, and also it causes leaks around the filter on remote oil filter set up's. Regards to ALL!!! Mike :grin:

High oil level

Was the boat sitting level in the water when you checked the dipstick or was it on the trailer? The dip stick is marked to give a correct reading only when the engine is sitting in the proper atitude (positioned as it sits in the water). Also, did you run the engine to fill the filter with oil?
