The boat that I have taken over is a 1973 Hydrafoil Corp. Hydrastep22 built in Florida It has a Firm Fiberglass Hull and Cuddy with a 1973 Ford 5.0L. It was my understanding that the outdrive was a mercruiser but it was rebuilt 140hrs ago and was called a "MR" outdrive. I have never heard of this type of outdrive before. It is a black outdrive and looks similar to a Mercruiser but there are no identifying markings. Has anybody heard of a MR outdrive.Thanks for any feed back.
