OK; Yam's manual says 25 US Oz, just shy of a quart. Don't know what length shaft that was for, but can't be that different, can it?
I guessed that the OP's 70hp had a comparable sized gearbox to my F60. I didn't think they were making "big foot" (or whatever they are called) oversized gearboxes back then. And seems like most 50/60/70 hps have the same sized legs. 90/100/115hp legs seem to be the next size up. I buy gear oil by the quart and it seems to last about 3 changes, but I end up dripping alot in the process.
Ok edit I looked my Yam F60 up, 14 US oz = 0.4L
