What type of grease to use on intermediate bearing housing for AR190

[JayHat]

Was looking around to see if there is a special grease I should be using on the intermediate housing in my 2021 Yamaha ar190. Also, what’s the verdict on keeping the motor compartment forward drain plug open or close? Thanks for the tips y’all!

I’m using Lucas oil 10682 marine grease

Agree, Lucas Marine Grease

Yep, that’s what I use on my 2020 SX190.

I stick to the Yamaha marine grease.. yeah it's more expensive, but you use so little it lasts forever. I also use it for the trailer bearings.
As far as the drain plugs. Closed in the water, open on land, although if I leave them close all the time.

How many pumps of grease do you guys recommend applying to the intermediate housing at the 10 hour service? Anything else that I should look into besides changing the oil and filter during the 10 hour service? Thanks so much for all of your help!

 

[HangOutdoors]

@JayHat I just put in 2 or 3 pumps for good measure at the 10hr.

I would reference the manual. It's measured out in .oz.
Pull the rear bilge cover check all the hose clamps. Not a fun job but I found 2 hose clamps so loose I could spin them by hand

Not all grease is compatible with others and can do damage when mixed. Yamalube marine grease is a lithium soap base, but the exact type is not disclosed. (Yamalube® Marine Grease - Yamaha Motor Canada).

Check this page Grease Compatibility Chart and Reference Guide and pay close attention to this statement:

"The compatibility of polyurea greases with soap-thickened greases is probably the most debated area of grease compatibility today. Greases based on simple lithium soaps (lithium stearate or lithium 12-hydroxystearate) and lithium complex soaps (containing simple soap and a complexing agent, such as lithium azelate) may or may not be compatible with polyurea greases. ".

For this reason, the other grease may be better but I am sticking with Yamalube in this application.

Thank you for that information. I will check the chart!

One thing I would like to contribute is that the owner manual says YAMALUBE Maine grease or Yamaha grease A can be used at the points asking to be lubricated including the intermediate housing . Reading the back of the YAMALUBE marine grease tube I have, they do state that it is "highly compatible with a variety of other greases". You can get Yamalube Marine Grease on Amazon for about $15

In the manual for the 2021 AR190 it does not check lubricating the intermediate housing as a thing to do during the 10 hour service. It says do do it every 100. I have read on other threads that they used to not ship with much grease. Going by the manual it would suggest that it comes with a proper level of grease when shipped from the factory. Crazy something so simple can become complex to find accurate answers. Happy Boating Y'all!

It's actually not in that section, at least for the 2020 manual. The manual states to grease the bearing for the 10 hour service in the care an maintenance section below.

The number of pumps depends on your grease gun. For me, it took about 30 pumps from the gun. Just go slow and and it should be fine. You can feel the line as well since it will get stiff as it gets filled.

Good luck!

30 pumps seems like an awful lot, if you put too much in and blow your seal that is very bad. You do see that the grease capacity is just over 1 oz and that is total volume. I would not suggest anyone put 30 pumps in there. There are proper threads on here on how to do it properly and safely.

Further more, an average grease gun will pump somewhere between 2.2cc and 3.0 cc per pump. Considering 1 oz is equivalent to just under 30 cc and you did 30 pumps you may be forcing too much in there. If you are going to be specific measure the output of your grease gun so you know what it is doing. I checked mine before I used it for anything.

Also there is another zerk fitting at the bottom of the hose on the 1.8's unless they changed it, where it goes into the housing. Pumping into the top zerk, if this is what was done, does not guarantee it is pushing into the intermediate bearing housing. You may just be filling the hose.

1oz per stroke for a manual grease gun is allot... All the ones I've ever owned only pumped a fraction of an ounce per stroke. It would be nice to have one that pumps that much per stroke for my tractor...
...
Yeah, the initial 10 hour service calls for 1.11 - 1.18 oz which for my gun comes out to a little more the 37 pumps (Amazon.com: LockNLube Professional Pistol-Grip Grease Gun: Home Improvement ). This is for the 2020 212s. It has a long tube connected to the housing to relocate the grease fitting to make it easier. Not all models have that. If not, then its allot less grease since you don't have to fill the line with grease in order for it to get to the housing. You would have to check that specific manual for the amount since I am not sure.

After the 10 hour, it calls for .20-.27 oz every 100 hours OR 6 months, so then I pump 7 pumps which is a little less than that.

That's all from the manual pic I posted above. I tend to just do what the manual calls out since I am not smart enough to improvise . Lots of poeple do remove the hose and go direct, again I just do what the manual says. The service manual says to do the same.

If you feel the tube between the housing and grease fitting you will notice it getting stiff as you pump it full of grease. The 1st time I did it, I felt the very bottom of it (the end closest to the housing) as I pumped (a pain btw) so I knew when the grease reached the housing.

I actually did the same thing for my 2009 FS SHO (same housing and tube except with a supercharged engine) and never had a problem... At the end of the season I usually just pump some grease into the housing while I do the rest of my end of season maintenance.

Hope the helps!

Not sure where you are getting 1 oz per stroke from in reading my post as I indicated it is between, on average 2.2cc - 3 cc. Perhaps you misread it. I do see that your gun pumps less than the average per stroke.

Additionally, I tend to follow the recommendations of members who run 1000's of hours on their engines over the manual, such as @Cobra Jet Steering LLC as well as others on how to grease the intermediate bearing correctly and safely.

There are those whom pump too much and blow their seals.

Also, the grease you pump into the hose gets old and then you force that old grease down every time you pump new grease into the top of the hose at the zerk. Poor design imho, hence the recommendation to add grease at the lower zerk or remove the zerk and use dental syringes.

But each to their own!

Sorry, my bad, I missed the decimal point and saw 22, lol. No doubt there are allot of expert users on here that know way more than I. I just tend to follow the manufactures directions in situations like this since there seems to be conflicting information out there. No doubt, you can blow your seal if you do screw it up so you need to be careful.
