I have 2 boats and use this in both of them. It has been over 10 years since I began using Amsoil in them and they both run well, and have not shown signs of wear.

Used this for years in a Yamaha 250 Outboard lower unit. The Easy-Pack is just that - very easy to squeeze into place. Best on the market!

Great product

Like the squeeze pouch.

Easy to install with the soft bottle

This is the best gear oil. I have it in my boat motor.

i do like the amsoil lower unit fluid. It’s seemed to work well. when i drain out the old fluid at the end of the season, it still looks new. The easy packs could be resigned somehow. it’s hard to get the last little bit out of the bags.

This last summer was the first year with 100% Amsoil in the lower unit, I had been putting the last .2 qt in from a bottle of Lucas that met the required spec. This was also the first year I had zero shifting issues and it ran flawlessly all while sitting in wet slip for 6 months

Have used this product in the lower units since new. 19 years. Never had a failure. Great product.

Put this in my buddies Mercury 115 the last three years and it’s cleaning up what ever was in it when he bought it used. My Yamahas only see Amsoil gear oil and it looks good each year for the change before winter sets in

Good quality marine lube in an easy fill container.

Worked great

Best oil on the market. Full synthetic 10W/40, after 100 hours on 250 Yamahas oil still looks good. Highly recommended. Been using this oil for years!

Just did the first 100 hr service on my new Yamaha VF90. Manual called for 90 but this 75w-90 is all that’s offered from Amsoil. Hopefully it’ll be fine.

Using this product in our out boards has been great We have inspected our gears sets and found them in superb condition Just to clarify my out boat is twenty years old and has only eve had this oil in it My boat goes3-5 times per week and more with weather permitting

Used in my Evinrude motor, like the fact it is synthetic. Works great would recommend.

Very easy to install, need gear pump to get into lower unit. I am confident this is the best lubricant money can buy for a $25k marina outboard motor.

Been using this oil for years in my outboard and it performs excellent, also got rid of a clunk inhad when going to reverse/forward. Highly recommended this for any marine applications

the only thing i will use in my boat

using this in my Suzuki gives peace of mind
