All I know about this salvaged Volvo penta outdrive is the approxiomate year & the serial which is PZNR 27127221. Besides that, I would love to know the gear ratio. I do think its a 1987. I've included pictures. Thanks for your help.

its in serious need of rebuild. looks like it had water in the bellow for a long time. the input shaft will need to be replaced, the upper gear box re-sealed and shimmed, and the lower skeg replaced.

Other than that, its a volvo 290 drive

Not a 290, wrong exhaust port. If it is from 1987 its most likely a 275. I agree with Scott, those ujoint are nasty.
