I have a 1994 70HP Force outboard. It's on a 1994 Spectum Dominator 17 which is a a 17' aluminum bass boat, similar to 17' BassTrackers. I was wondering if anyone knew or could point me to a place to find the OEM prop size for this outboard. I haven't inspected the currently installed prop yet to see exactly what size it is. It seems to do fine now with what is installed but I would like to get a new one and keep this prop as a spare.

I should add my tach doesn't work so I do not know what my WOT RPM's are which I know is a big factor in prop sizing.

They come in sizes from 8p to 17p
Take yours off and see what's there.
And like you said, no tach, no use!

Your motor uses a very common prop size.
It was used on Merc 40 - 60 hp motors for 30 years.
Check the numbers on the side of the prop, or remove it and check the numbers on the end of the hub.
Then buy similar.
