Aloha Chris,

There is a manual called "Outboard Motor Service Manual: Covering
Motors Below 30 HP from 1969". Check it out at www.marineengine.com.
Key in 8 hp yamaha in the search area for engine manuals. Hopefully
it has the specs you're looking for.

Thanks for that I have just ordered it from Amazon thanks for the info
