Got a 08 moomba mobius with a 325 assault and I'm wondering what oil filter I'm supposed to use. Are the filters supposed to be marine specified or is there such a thing? I thought this motor was a GM 5.7L so I figured I could use a ac Delco filter for that engine and order it from GM dealer or am I wrong? Also I'm unsure of the weight of oIL I need to use and what brand it needs to be or does brand not matter?

Can anyone tell me what this motor really is and what I need for an oil change?

Thanks

There is a sticky in the HOW TO section with all the specs, etc. for your engine, which is a Chevy 5.7L. Here's a link to what you need:

BTW, if someone remembers what size cotter pin that was somebody asked about the other day I'll add it to the thread along withe the prop nut info.

OK I work at a dealership and we stock the PF25 but it's the classic version. It's not blue like typical filters from ac Delco are,it's white and it has a big red AC logo and says full flow. I assume this will still work.
So my other question is..I'm seeing some stores selling marine grade oil. What is the difference in marine grade, Conventional, and synthetic?

Kane, how can I tell if my engine has catalytic converters? I thought it did but after reading the manual I found on indmars site I'm thinking differently.

the 325 Assault does not have Cats, only the 340 with a black intake. Yours should have a plastic cover on top of the engine and then a round flame arrestor under that.

Does anyone fill the new oil filter up half way before installing to the engine?

Fill mine pretty much all the way. Same with all my vehicles where the filter is mounted vertical.

OK cool. So my engine holds 5.5 quarts. Will I still fill the engine with 5.5 quarts on top of filling the filter?

I put 5 quarts in start it and check and add from there.

like stated above, I put in 5 and let it run and warm up and then recheck/top off as needed. One tip on removing the oil filter I learned here is loosen the filter up just enough so you can do the rest by hand. place a large zip lock bag around the filter and then finish removing it with the bag around it in case it drips. I also put a large old rag/towel under as well incase anything drips.

Search for "engine id" or "what motor".
The first link has pics . . .

The ziplock bag works great when removing filters.

I always fill my truck or boat filters to the top when putting them back on.
I do the same process as above, start with 5, check, add some oil, check, done.
Not looking to overfill.

I always check my oil when I drop it in at the boat ramp. It's a habit, not sure everyone does this each time.
Since I store most all of my equipment in the back 2 lockers, it does not take a big effort for me to open the engine compartment and check oil level.

That's actually the recommended way to check and get's the most accurate reading (when level in water with no ballast or loaded).
Confirms where it should be although doing it on the trailer will get pretty damn close unless you have it at a big angle towards the bow or aft.
