Volvo Penta Cobra SX repair

[zbob]

My SX sterndrive failed after running low on oil. I know. Should have known better.
Have a 1998 VP cobra SX-C 3868584, 1.79 R. I assume 21-26 gears.
VP V6 4.3l GL PBYC.
I am a DIY guy, getting ready to pull it. Am thinking maybe the upper gear case can be replaced to fix this problem. I understand the SX=A are newer than the C models and are not backwards compatible. My Seloc manual shows that a M model is applicable. Can I use the M model upper gearcase? I need advice/ guidance please. Need a list reputable companies that offer rebuilt and new gear cases too. I think the lower gearcase is good, and will find out soon...................

Throw the seloc manual away and get a factory manual

You have to rebuild the whole drive. Grenaded parts from the top make it to the bottom

It would be cheaper and faster to find a different drive

Thank you. Any idea where to buy quality rebuilt drive? Can an M replace a C with the same gear Ratio?

Check Ebay. They seem to carry a good selection of used and rebuilt units. Sell yours for parts to recoup some of the cost.

I would look at sites like https://www.freshwatervolvopentaparts.com/ and get a complete good used drive.

I’ve had good luck with boatwrench.com for rebuilt drives. They are easier to reach than freshwater.
