Dont know the D2-55, but the MD series use a Mitsubishi starter. Nothing special, off the shelf automotive grade starter, sprayed green...like most Volvo
parts and motors. Volvo
price: $850. Auto
parts store: $85 or less.
I suggest pulling the starter and looking for manufacturer's marks. Added bonus to this approach is you get to do it once in a controlled situation (like at the dock). The MD series is a bitch to pull...you need a stupid long extension that will reach from the front of the
engine, underneath the heat eachanger, to the starter, to get to the upper starter bolt...practically inaccessible any other way...best to learn that somewhere besides mid ocean.
