I have a full SSM4 conversion here
Boat has been sitting but everything spins nice and feels great, transmissions worked when parked a few years ago so should now, I see no reason why not.

You get
2 SSM4 small shaft drives 19 spline
2- transom assemblies with trim cylinders and lines to cylinders
2- Extension boxes
2- carrier bearings and driveshafts
2- 72c transmissions with driveline style tailstocks
All parts from transmissions back to prop shaft that you need

Came from Tripple engine boat so no tie bar or steering plates, I do have a tie bar and plates separate for another 1000.00 from ssmiii parts I have here

18,000.00 picked up 44138 Ohio

Parting entire boat so lots of parts to be listed

Would you sell the two #4 drives without gimbles? I could possibly trade you two 3’s
