             D Driveshafts for the Mercury Mark 55H or Mod engines.

    

There are three versions available, the standard Mark 55H, a second in the standard length with five (5) inches of crankshaft splines and the third that is two (2) inches  longer which can be cut down to any length for use with a coupler.  The standard length with the longer splines can be cut off up to four (4) inches so a coupler does not have to be used for a shorter shaft length.  All of the shafts are made like the originals including heat treating and hardening in the bearing area.

Prices                               Standard length                                $295.00        

                                                    Longer length                                    $225.00

                 Mark 30H and Mark 20H Driveshafts

            

        

Made from Mercury plans and checked against an NOS C shaft.  These are the standard Mark 30H shaft and the Mark 20H shaft that uses the Mark 30H bottom end and the 16 mm 6202/16 bearing. This shaft has been called the Metric shaft due to the use of this larger bearing.  Also available is a cut down version of the C shaft for use on a Mod unit.  You just have to make a coupling on the top and you  are set to go.
