What parts would I need and where would I best source them from? Sierra maybe? here
Anyway, my question is, is this something I could tackle myself? As a bit of background, I'm fairly mechanically minded, and have rebuilt my fair share of motors, if that helps. here
I'm currently in the process of repowering my 1998 4.3GL Volvo Penta and having taken off the outdrive (It's an SX but I'm not sure of the exact code, I can grab a serial number if need be.), I've noticed some oil in the U-joint bellows and also coming from around the prop shaft. So now it's got me thinking that it might be worthwhile to replace all the seals in the upper and lower unit as I have never had it done while the boat has been in my possession and the previous owners maintenance habits were sporadic at best.
Any special tools I'll need or can I get away with other methods? here
And finally, anyone have any wisdom they'd like to share on how to go about it all? more

Wipe away dirt and debris from the exhaust port. Wipe a small amount of bellow sealant from the kit onto both the exhaust port and the inside of the bellow and then slip the new clamp and bellow in place. Tighten the clamp with the Phillips screwdriver. Slide the new clamp over the U-joint and then wipe bellow sealant on the inside of the joint bellow and then slip it on. Tighten the clamp with the screwdriver. [links]
Use a Phillips screwdriver to remove the clamps holding the old exhaust port and U-joint bellows in place. If necessary, cut the old bellows away with a sharp knife. [links]
Lift the outdrive lower unit and replace the mounting bolts.
Use a socket set to remove the propeller nut and then pull the propeller nut, along with the propeller, off the bottom of the outdrive.
Remove the nuts holding the trim pistons in place on the outdrive with the socket set and then hang them out of the way with a bungee cord. more
I was under the impression that the 200-thru 280 used the volvo cut out and the 290 and sx/cobra used the merc cut out?? My point being going from a 280 or older to a newer 290 or sx would mean glass work on the transom . If that's not the case I sure would like to know .
I do not know the outdrive's ratio ? here
CLYMER Stern Drive Shop Manual 1968-1993 has helped me out over the years. It is about 2/3 motor and 1/3 drive in content. There is also a 270T Volvo drive. I believe that is what I have on my 16. There is one long cylinder inside on top for tilt and one short cylinder outside, on the bottom of the transom plate, for trim. Maybe your 270 could be converted to a 270T with only a few parts.

It is a fun & interesting project !
