My gimball ring pin were changed for the oem merc steel pin for many hundreds each... What about those for sale on ebay made of stainless for 125$? Is stainless steel harder than the oem steel pin? If so, why even use softer oem steel pin much more expensive? Anyone used the stainless pin? What are the results on the long term?
Question only for my curiosity since my gimball are all redone oem, but i would like to know

Also, wondering what oil brand and grade mercruiser suggest to use for drive trim pump? I would like to have some spare oil just in case i ever need some on the water.

Thanks!

Tough question i guess!!!

Post this in the technical section of the site.

I dont know about the pin, but im pretty sure the trim pump uses 10w30 or transmission fluid. Mine still has the sticker on it and im thinking it said 10w30

I don't know the specific hardness of either pin. But stainless can normally be softer than steel because of the alloys used.

Merc makes power trim/steering fluid. I'm guessing this is what they will reccomend. It's expensive though.

think you can use 10w 30. The steel pin is prone to rust, kills the seal and water gets in. SS shouldn't rust as easy thus keeping the seal.
