Ok so here is a tip from your friendly neighborhood marine tech. Good job on the whole process, but use oil instead of grease the next go around. Oil will soak into the pores of the rubber gasket and provide a solid seal against the mating surface. Also I see that you are following Mercury's service intervals based on your comments here. That's good, but oil is cheaper than iron. Don't be afraid to change the oil at half the service interval as recommended by Mercury.....especially if your fishing includes a ton of graphing and idling. I will typically change out the oil on my Mercury 150 4S every 50 hours both for engine oil and lower unit oil. Also I know they say the yellow gaskets can be reused, but they are cheap so go ahead and install a new one for each plug each time you break the seal on the screw. Lastly if you haven't already you should sign up for a BBC boards account and join the Mercury FourStroke forum. Don Weed is the moderator and is by FAR in my opinion the most reputable Mercury Service Tech in the country. Good fishing and tight lines bro!
It looks like the same exact Mercury 150 outboard that i have. When i did mine (had a marine mechanic help me), it did not take all 6 quarts of the oil, it was more like 5 and 2/3 of the 6th quart. Always easier to add more than it is to take overfill out was the advise i was given. We ran it with new oil and checked it, it was spot on. I'm curious if others have an opinion on this.
Yes this is correct. You want the oil to be in between the full and low marks on your dipstick. Over filling of these engines can cause several issues such as "frothing" of the oil in the pan. When oil is aerated it won't provide near the lubrication. If you are at the mid point or slightly above on your dip stick you are in the green. Happy boating.
Only recommendation I would have, is to use Mercury’s synthetic blend, rather than the conventional here. More protection for your engine. I also run 25w40 in the summer.
I got mine off of amazon, but I just looked and couldn't find it. You might contact Mercury directly or contact a dealer. Also all the parts are on amazon
fishnbaja1 if someone could tell me why, that would be awesome. Cuz let me tell ya it was extremely hard to remove the filter. I’ve always used grease without a problem. This seems to be a 50/50 opinion, but no one can tell me why not use it.
@@NathanBromley Sorry about the caps. The Mercury manual says not to use grease. I tried to find out why exactly, and there wasn't much information. One article seems to imply that grease is not liquid and may clog the filter if it gets in there. You've used grease for a while and haven't had that problem, so.... Great videos, BTW.

Never use grease on the oil filter gasket. Use oil!
tjk6277 why?
I understand the directions say not to, but no one can tell me why. I always have.. Do you know?
It is because the grease will containminated the oil ,but it is just little wont harm the engine .By the way How many hours on your 150mercs?
A T probably somewhere around 300. It’s a year later so I’m ready for the 2 year maintenance
@@NathanBromley grease will contaminate the engine.
Where did you get the 150hp oil change kit?

Bucketmouth Bromley Thanks!
Never use grease oil only
What size is the hose
should be 7/16 but some people use 1/2 inch
Omg. No. 🤦🏼♀️Do not use that GREASE Good till I saw that. Just use new oil dab your finger in it and wipe it all around the gasket seal.
Jeni G. I’ve always used grease on oil filters. What’s the reasoning behind using new oil instead of grease?
Nathan Bromley it activates the rubber seal to make a better seal. Same process should be applied when doing your car engine oil filter.
use the same oil your using on the seal not grease.
DO NOT USE GREASE!!
