SAE 140 oil vs 00 Grease?

[GDTRFB]

I was speaking with a Vintage Outboard Engine restorer yesterday. He asked what kind of grease I run in the lower end of my Silver Century Plus. I told him nothing but straight SAE 140 gear oil. He said to me the stuff was rubbish and that was old school thinking to still be using that. He said he runs a 00 grease in all of his vintage outboards he repairs or owns himself, of which he said he has over 700 (parts and complete units). I told him I never heard of it. His reply was it is a pourable water resistent light grease made for gear units that have bushings and aren't water tight.

Has anyone heard of it, used it or can comment at all on this stuff?

There is a lot of debate about this. Bruce has a lot knowledge. I've drawn my own conclusion and that is to have a heavy oil that is semi water soluble. Seagulls are designed to have ingress of water into box and as such the lubricant needs to be part water soluble. I prefer to have liquid for the splash factor that the crown gear creates ensuring lubrication throughout. Soluble grease will work but would require more diligence in topping up.

With my nippled gearboxes I will be running non soluble marine grease on the two top bushes and heavy soluble marine oil in gear area.

Mobil has one that I like. Designed for emulsification with salt water and has a 20% solubility factor. Viscosity of 385 at 40C. Smallest container is 20L though.

All the dry gearboxes I have come across have had grease not oil. Both will work, IMHO, if maintenance is regularly performed.

I run 90 grade in my Kingfisher and Model 110, as per manufacturer's specifications. I run 140 grade in the forties and Centuries, as per manufacturer's specifications.

Older 102 models are a bit of a special case, as we have discussed many times here.

In other words why differ from the factoryspecified lubricant? After all they only closed down 14 years ago or so!

And the use of water resistant stuff is at best questionable. It has to emulsify.

That AMSOIL Semi-Fluid 00 Synthetic EP Grease lists in the USA as 342.65 USD per 35 pound weight tub, not including shipping.

Weight for weight that is approximately 4.4 times more expensive than SAE 140 here in the UK when bought mail order with free shipping in 5 litre cans on eBay. (Slide rule accuracy).

That 35lb minimum size tub costs 225 GBP and is approximately equal to 17.3 litres of SAE140 in weight!
