You will need the specifics of your own engine
to obtain the correct starter. IF you didn't receive the original papers fro your yacht when you bought her, there is a plate on the sife of the block with the engine
number although it is difficult to access. You may also need the spacer that goes between the starter and the mount. Having had to replace the starter on our engine, I can tell you it is a serious pain in the butt--really serious. If CSY
Man's small size starter will work, on your unit, it will make life a lot easier if you ever do have to replace the unit.
