Twin Disc Marine MG-5075A , 1.77:1 Ratio Marine Transmission / Gearbox

Description

Twin Disc Marine MG-5075A , 1.77:1 Ratio Marine Transmission / Gearbox. Includes 12V electric shift valves, input coupler (needs new rubber inserts), and SAE adapter to bolt up to Cummins 6CTA with 11.5" flywheel.  The 5075A version has the down angle output shaft.  Data Plate picture in this listing.  The info is a bit hard to read so the BOM # is S-14807 and SN is 5HZ961.
Removed from 2004 40' Riviera FB with 1600 hours.  Was working perfectly at the time and had been regularly serviced.  Pictures show weld repair on housing where small crack had formed (non-structural and likely due to a small casting imperfection per the Twin Disc Service dept).
Ready to ship.  About 300lbs with coupler and shipping pallet so it needs to go by LTL truck.  Ebay listing doesn't support freight shipping so I put 0 flat rate but I'll coordinate shipping and payment for shipping (actual cost only) with Buyer after purchase. Or you can pick it up in San Diego.
No warranty or returns but I'm happy to work with potential buyer to ship to to Palmer Johnson or other Twin Disc service center for evaluation/test run before purchase.
