Good job to have done I got to get my motor serviced. The bass are hitting on the Richiboucto but I haven't been out yet busy getting ready with the build.
TF-I'm hearing the Stripers are in the bays and the boys are getting them. Another week and I'll be heading up! Good luck with the build and hope you vlog some of it.
Thank-you for this video. I'm going to look at/purchase a used 2018 90hp tomorrow. I'm changing boats and graduating from a 60hp. I guess I'll check the lower unit oil when I get it home. It's probably due a 100hr service anyway.
First time I've ever seen the lower unit oil drain/fill plug in the the prop exhaust hub. Both my Merc 40 and various Johnson/Evinrude V-4's have the drain/fill plug on the slightly forward lower side of the gearcase and the vent plug just above the anti cavitation plate.
My 2010 90hp 4 stroke efi has a straight engine oil plug bolt . Can you change to the hose hook up you have ? If so would you know the number on the plug ?
Tim, I had a 2008 motor like yours with the oil plug bolt. Always was a mess and I'm not sure if you replace it with the new style. I'll have a look for the part number tmr and Id confirm with a dealership.
Just checked the hose hook up and there's no part number on it. I'm not sure it can be removed. The owners manual states to not turn it anymore than a couple times as you could strip it!
The manual says 666 ml or 22.5 fluid ounces. I never measure it. Just have a full bottle and pump it until she starts coming out of the top vent hole. Stay safe!
@@MasterCrowOutdoors I just bought a 2015 mercury 115/80 jet, and the dealer gave me 25w40 to put in it. I just wanted to make sure I wasn't messing something up by using to thick oil. I just spoke to the dealer and he said to run the 25w40 in summer and 10w30 in winter.
Awesome thanks, I am struggling to find 7/16" inside diameter tubing anywhere, I might just have to use 1/2". That's all I can find here in BC. Great video very helpful, thank you

It's that time of year again! Nice fresh motor for another season!
Yup!
Thanks for that, I was looking at a 75 tonight on a trailer, thinking where is the drain screw. Now I know. Thanks again.
Anytime. Glad I was able to help out!

Anytime my friend and changing the oil and lower unit fluid will only help. Safe boating and congrats on the upgrade!
Hey. Good quick short and sweet content. Nice vid. Thanks
Big-D Glad you enjoyed the vid. Have a great n safe boating season!

MB-It is a little more work than removing a drain plug, but I gotta give Merc credit for making the motors a lot more user friendly for servicing.
Per-fect quick easy video, thanks
Appreciate that! Hope you share and subscribe. & stay safe!
Scott-Yes sir, nothing worse that being stranded on the high seas!
Or anywhere else!
Great video. Is there any reason you couldn't fill the gear lube from the vent hole until it starts to pour out?
Yes, I don't think it will fill properly due to air locks.
@@MasterCrowOutdoors thanks for the quick response!!
@@jaycrockett3260 Anytime!
Good stuff man!
JS-Would prefer to do it at the end of the season, but she's a little chilly up here in mid December!
What happens if I loosen the drain valve too much and break the seal?
I'm no mechanic, but my understanding is that you'll most likely develop an oil leak.

How many quarts of gear oil? Thanks.

why do you use 25w40 instead of the 10w30 as stated on sticker?
That's a great point! My sticker says 10w30 also, but the Owners Manual does say 25w40. Strange?

@@troydunn04 Smart move. The dealer will typically steer you in the right direction. Have a great season and stay safe!
Do you know what size socket to get the prop off?
I believe it's a 1 1/16"
What size is the oil drain tube required for this? 7/16" is the inside or outside diameter?
12mm or 7/16" is the inside diameter!
Awesome thanks, I am struggling to find 7/16" inside diameter tubing anywhere, I might just have to use 1/2". That's all I can find here in BC. Great video very helpful, thank you
@@paulbennett107 Glad to help out. I also couldn't find 7/16" inside diameter, so I heated the tubing up carefully n that worked.
I couldn't find the 7/16 ID tubing so used 1/2" instead. It worked fine without modification.
Thanks man.
Glad I was able to help out. Have a great season n stay safe!
You really shouldn’t use your torque wrench to loosen…just a question of calibration
Is it because it will through the calibration of the torque wrench off? Really appreciate you telling me that!
Ddigd
Not sure what that means, but hope the vid was helpful!
