A/B quickie lower unit

What kind of oil or grease and how much does a A/B quickie gearcase take.
Thanks

Every Quicksilver gear case that I return to an owner gets filled with #0, Lithium soap, EP grease. It is a very thin grease, and flows easily thru the unit. The EP additive, (Extreme Pressure) is similar to that which protects the gear sets in automotive rear ends. Mercury’s Special Gear Lubricant was a #0 grease. NLA from Mercury Marine. I purchase the lube in 35 pound tubs, and have used as much as 70# per year. An acceptable, commonly avalable grease is John Deere’s Corn Head Grease. It is not Lithium based, but it is #0, and is pretty good at protecting after water intrudes. I beleive the Quicksilver cases hold about 2 ounces of grease. I suggest they be lubed after bing used, and before storage. Tail cone needle bearings require thicker lube (#2) and if the seals are good should be lubed about every 8-10 racing heats.

Do all tail cones have needle bearings? Mine seams to have just a brass bushing.

You have the older brass bushing tail cone, no lube there but for storage I would pull off the cone and grease the prop shaft and reinstall the cone to keep the corrosion down. The corn head is a great grease for the gears in the old cases it is a 0 at rest and becomes more fluid with gear motion then immediately goes back to 0 when motion stops. If you have good seals water will be kept out but regrease the gears often like after each use to keep the case in good shape. They are expensive to get parts and fix, grease is cheaper than parts. These quicki’s were not sealed that well with the type seals used.

FYI on the quicki’s I use with cone needles I find the #2 grease to thick and the rollers tend to slide rather than roll. I find the corn head grease in the cone works best for me and no water entry issues, and seals always need to be in good shape.
