Checking the iboats VP site for lubes and I don't see the 75W90 listed but instead "Synthetic Transmission Oil" which is API GL-5 rated but doesn't say anything about the viscosity.

Can anyone clarify if this is the right stuff?
Thanks

You have a link?

There are 2 viscosity available so you have to select which one.

If you zoom in on one of the pictures, it says 75w-140 so not the correct lube. May need to call to make sure.

The part number of 1141679 is correct though!

I have found that buying this on the net is not cost effective. Shipping kills any savings. For 2 of these shipping to me is $11

I always buy by the gallon so shipping on that is $8. May be worth it if you buy it that way.

THanks, yes I was considering a larger volume to save shipping since I will need it in the future and I wouldn't think it would go bad :)

It takes around 1/2 gallon so I always have another one handy. My pump screws right into the container.
