    frozen steering/cable questions

    All right guys, I know this has been posted before (I did a search) but the steering froze up on me on my Yamaha 70hp 2 stroke and have a few questions.

    prop selection?

V-bottom I guess (6 degree deadrise at transom). It also has a skeg about 1.25" that runs all the...
