I have a 2000 Macgregor 26X with an Evinrude 50 HP engine. A nut on the steering linkage has corroded and broken off rendering the steering system useless. The nut is located on the outside of the boat, in front of the engine and connects the steering wheel linkage to the engine and rudder linkage. All the parts still move, but without the nut, the steering wheel will not move the rudder and engine. Sorry for not being more specific but the steering system is not in the owners manual and I can't find anything online. Anyone out there know what this part is, where to get a replacement and how to replace it? I can provide pics if needed. Thanks.
