1997 American Skier Volante
« on: May 03, 2020, 05:01:09 PM »
Hey guys, I bought this boat from sister 2 years ago and its due for an oil change.  I have the service manuels and the part number for the oil filter doesn't exist. The engine is 5.7 Vortec, would it be the same as a car oil filter or these different??   10w30 fine?  Thanks!!!!

Yes, oil filter is the same.
Just make sure you have an oil that has enough ZDDP.
Most people use a 15W-40 or 20W-50 in marine engines. Most modern standard 10W-30 oils don't have the ZDDP levels suitable for flat tappet engines.
The suitable oil should be addessed in the manuals you say you have.
When people run down to the lake to see what is making that noise, you've succeeded.

The boat came with 2 books, parts manual and the other engine service manual, neither of them say what type of oil to use but I did see the 5.7 uses roller lifters instead of tappet style. Now it did give the part number for oil filter but nothing pulls up.  So, do I still use the heavier weight oil or just 10w 30??

Marine engines generally like a little heavier oil but it depends on how close the tolerances were built into it. If you know how much oil pressure you were previously running when cold and warm at idle and at speed you have a good base. I would say you should be safe with 10-30 or a good quality 10-40. Watch the oil pressure and adjust accordingly.
