For auction is a ZF HURTH 280A marine transmission, comes complete with original oil pump and SAE#3 adapter plate, not shown in pics, the input and output shafts turn without issues and the shifting block go's into three position smoothly. from what information I obtained was the unit would sometimes not engage into forward, the shifter would though. this can be an easy fix, one of two issues the select valve block needs cleaning or rebuild, or the forward piston seals needs to be changed. If you are interested in our shop rebuilding this unit contact me for additional cost and we will revise the listing for and easy transaction. Any questions please let me know
