Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.027". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.This Part Fits:

The best lower unit gear oil I have used
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
I have been boating my whole life, this is by far the best gear oil. I use this in my Johnson 115 even though this is technically made by Mercury. I seem to get less if any water intrusion into my gearcase with this oil. If there is any, the oil emulsifies the water and continues to protect the gears. I have had better luck with this than Pennzoil marine or others. Highly recommend. It is a blue color and easy to drain and fill.

Does not come with a pump.
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
The Good: Changing the fluid in the lower unit is a very easy DIY job. This can save you hundreds of dollars each year by doing it yourself.
The Bad: You need a special pump to change the oil, and sometimes it comes with the gear lube. Unfortunately this product did not come with it. Luckily my neighbor had an extra one from changing the lube a different boat laying around and was able to use that.
The Ugly: If you have to go get the pump, that could cost a few extra dollar but is just an extra nuisance. The pumps are interchangable but you just need to clean it between uses (DON'T MIX DIFFERENT OIL BRANDS)
