A method of processing the connecting surfaces between a marine engine frame and an associated bearing support, which parts wholly or partially surround a crankshaft is presented. The bearing support is removed to expose the connecting surface of the engine frame facing towards the bearing support. An auxiliary plane is established which is set-up/extended along the centerline of the crankshaft, and a second line at right-angles to the centerline. In situ processing of the connecting surface of the engine frame is effected at an angle which is a function of the position of the auxiliary plane. It is thus possible to process the connecting surface of the engine frame facing towards the bearing support without the necessity of having to remove the engine frame itself, and to carry out the processing of at least this free connecting surface, while the actual bearing support can be processed in the normal manner.
