Yamalube is it worth it?

[Nick Hearne]

Should I be using Genuine Yamaha Yamalube SAE90 API GL4 Outboard Gear Oil?
Or will this be just as good with out the Yami price tag?
COMMA GO45L 5L EP80W90 GL4 GEAR OIL - FREE TRACKED POSTAGE | eBay
I can get 5lt for the price of 1lt of yamalube and I have 3 gear boxes to do!
What do you recon?

if its the same grade to the same spec I'd go for the cheaper option pointless paying for the name!

your probably more likely to change it as its not making your eyes water every time you do it

no doubt someone will be along to tell you the yam stuff is designed for marine use & is more water repellent but imho the water should be on the outside & the oil on the inside if the two come into contact you have a problem IE a damaged seal

obviously if your changing the oil regularly you are more likely to find any water ingress early & hence get the source fixed before it does any damage

I asked there tech dept if it was suitable for outboards and was told it was

IMO, there isn't a whole lot special about marine gear lube. Maybe some additional corrosion inhibitors in case water gets in, but I can't see a whole lot else being different. And if water gets in to any great degree, the lubricity will decline pretty quick in any case, so I'm not convinced the corrosion inhibitors would be of much use anyway.

I use West Marine branded gear oil rather than the pricier name brands, but wouldn't e averse to using automotive gear oil if I needed to. Maybe check/change more often (or maybe not), but it wouldn't keep me up nights.
