Hey all,
I'm re-aligning the prop shaft on our 2000 SAN (5.7 Apex + Walter V-Drive). While I'm there, taking care of a number of other related/nearby odds and ends (new shaft/coupling, new strut bearings, new stuffing gland hose, new raw water hose, etc.). While taking things apart, I've been looking at the two aluminum cradle angles "supporting" the v-drive. One had no lags in it any longer, the other had two of the three, but loosely - no effective fastening to the bilge sidewall at all. Essentially, they're both just suspended there by the v-drive plate assemblies. Planning to re-fasten them after I align the prop shaft. Have been toying with how to best do that, since the existing 3/8" lags were either gone or ineffective.
Was planning to pot some studs (bolts, head-side in) into the cavities with epoxy, because the sidewalls appear to have only about 1/2" of material before foam. Today, I was drilling some injection holes above the original holes to aid in filling, and I discovered what appears to be a metal backing plate in there. Either AL or SS (swarf was long/bright and non magnetic). This has me rethinking approach a little.
Wondering, if instead of messing with potting these studs, I can get away with enlarging the holes in the AL cradle angles, and upsize the lags to 1/2" instead. Has anyone done this repair before? Does anyone know any of the specifics about that backing? I suspect that if the factory used a series of 3/8" lags originally, that replacing in-kind with upsized fasteners to gain some new purchase would probably suffice, but hoping for some collective wisdom from the board.
TIA!
