I have a 4.3 v6 Cobra. The outdrive is shot ( someone did a patch job on the case years before I got it and the patch gave it up on the lake one day and well, now the whole thing is toast. BTW, they put a ton of paint on it and neither me or the previous owner had any idea it was there.)
Shopping for a replacement and finding a few outdrives for 3.0 Cobras. Is it the same unit? Or is a 4.3 a different unit.
Thanks.

Ayuh,.... Even if another Cobra, the gear ratios are very different, 'n it won't work,...

The upper gear housings are the same but the lowers are different up to 90/91. Early 3.0s had a lighter duty lower that was eventually changed for the same one used on the V6/V8s.
And yes the gear ratios would be wrong for the 4.3.
