Are u talking about the spline where the u joint shaft came out of on the engine side?

it might look something like this, bolts to the rear of the flywheel, look through the hole where the drive shaft come out of to the rear of the engine

This is what mine looks like

coupler looks perfect

ok, sorry thats not like a Bravo 1 never mind

If anyone has any thoughts I could really use the help thnx. I will most likely take the stern drive in to ensure it is okay. Then take boat into a shop. 😭

Gotta be the rubber hub in the propellor, post a picture of the type prop you have.
from memory (1984-1989) the volvo prop hubs have what looks like the thrust washer from a merc prop built cast as part of the splined barrel the rubber hub is on so when it is pressed in the thrust washer fits inside and flush to the prop hub, and you cant see the rubber like on a merc. Stamp or scratch the prop hub and the part that looks like the thrust washer, the marks wont be aligned after a boat ride. Any prop shop can press in a new one.

I'll try to find a pic of a volvo prop splined hub.
