    Best oil and filter for '87 Mercruiser 5.7L GM?

    Have been running a 5.7 Merc in an '87 230WE on Mobile 1 15w 50 for 3 decades. Was thinking about changing over to Amsoil 25W 40 Marine. Any recommendations? (I've heard Amsoil is the best and i use it in my tow vehicle). Maybe I shouldn't change the type oil that I've been using for so long?

    Hi all, last summer my remote oil filter lines were showing signs of wear and were leaking oil into the bilge. It was a slow leak, but over time the bilge got pretty full of oil.

    Oil leak from filter hoses

    Hi all, I've been noticing the bilge in my boat getting thicker and thicker with oil lately. Figuring I had a leak, so I checked my oil level and it was indeed low. I looked around and found the hoses that connect to the oil filter have oil at the transition from pipe to hose. I cleaned all that...

    Changing Lower Unit Oil: Bravo III

    Replaced my lower unit oil last week. Followed the proper procedure as far as pumping in from bottom until oil came out top vent plug. I then put the vent plug back. I gave it 4-5 more pumps I noticed there was way to much oil in the reservoir so I took the bottom bolt off to let some drain...

    Oil recommendation for 4.3 Mercruiser

    hey all, I’ve recently purchased a 1990 sea ray 180 with 4.3 Mercruiser. It came with all documentation EXCEPT the engine manual. None of the paper work I have on it says what type of oil to use. I’m assuming a good synthetic 20w-50? I’m new to the inboard world. Thanks in advance!

    Synthetic or Regular Oil

    I purchased a 2017 Sea Ray 19SPX I/O with a 4.3L Mercruiser this year. I'm preparing to winterize it and I'm trying to find out if the engine came with synthetic oil or regular oil.

    Hi, Quick question. My old transmission on my 1989 Merc 454 I think is low on oil but I just need to know when I put the dipstick in should I screw it all the way in and than measure it or just put it in and pull it out without threading it in. And also do you have a recommended oil to use in...

    Hi there, I bought this boat with 15 hours on Rebuilt engines, and was confident as I got to see the entire invoice leaving the previous owner paying $20000 in the end. So far have had no issues and have about 100 hours on them since rebuild but when I checked the oil yesterday I noticed...

    Hello Club SeaRay!!! We bought a 99 340DA in June and are loving it! We take good care of it - better than our kids (yes I am kidding). I noticed a fair amount of oil in the bildge yesterday on both sides. I checked the filters and they are dry but above the filters there are two oil hoses...
