i did a search and didn't find much info, i need to get a new oil pan gasket and i am not sure if i need a special marine one or if i could just go to napa and get one. its 1990 454 carb 330hp markiv motor with the stock merc pan. thanks for the help--

get one from felpro marine

Save yourself some pain and get the Felpro one piece 1884-R gasket. Its more expensive but soooo much easier to deal with. A little dab of sealer at the corners is all you need.

Just got through using one. Got them at auto zone for 26.00. Forgot the part number but it was felpro and blue rubber. Only problem I had was the sales woman insisting on a cheaper cross referenced gasket. Obviously not the one I wanted because it was in a flat box. The one peice will be in box about 4 inches thick.

Yup, the one piece gasket is the way to go. I only use those on the MKIV 2 piece rear main seal motors. Much nicer to use and install. Plus if you ever need to take the pan off you can re-use it again!

tickfaw thats her the blue felpro white box, (brown box automotive)

thanks for the help i got the fel-pro coming from my napa guy.

I tried a one piece felpro, didn't actually fit that well. I ended up having an annoying leak all summer. You may want to go with the MR. Gasket Ultraseal - MRG-5883 on summit racing. It only costs $10 too.

The key is what you use with it though. I highly recommend using "The Right Stuff" gasket maker by Permatex. I've been told you can seal leaks externally with this stuff. It comes in a aerosol can too so it's easy to apply.

That's the current setup I'm using, no issues. Just my 2 pennies though.
