Jim Desnoyers comments about the mounting brackets for the P19 ladder being modified for M15s with the mounting brackets turned inboard may explain why mine, just received, appears defective, in that the support flange for the ladder, when the ladder is extended for use, meets the ladder tube at a sharp edge, not against the flat of the flange. I complained, and was told they are all that way and work ok. OK? It may also explain why the black plastic gizmo that holds the ladder up against the transom when the ladder is not in use is not aligned with the ladder tube, and when the ladder is up, one arm of the gizmo's "U" is bent way over, and the other is not doing anything. Was told that was ok too, that it will not break off in time. Think I'll take mine to my son-in-law who can drill stainless steel and remount the gizmo in proper alignment. Have other users of the P19 ladder on their M15s noted the same problems?
