Re: [OMC-Boats] Tru-course Steering

Hi Lee,

I'm still looking into it.  I've only had the boat in the water once this year and the steering locked up only one time and after that I remained cognizant to not turn to far.....but the challenge will always be....just how far is too far??   I'd rather not have to worry about it.

Coincidentally and related to this very topic, just this evening I got an unexpected offer of some spare Tru-course steering wheel and outdrive related components.  Not sure yet if the offer has financial strings attached.  In anycase, the offer doesn't include the cable but I've been watching them on eBay.  There are several listed of  differing sizes and costs.  I've asked for more info and pics of the parts. 

It sure FEELS like I've been spending a lot of nickels and dimes on my project and I know it would be a good investment comfort and safety wise but the combined costs to making it happen is causing me to consider the prospects carefully. 

Stay tuned!

So Bill,
What's you plan for a "true"  course correction?

But what you don't see the are the dual Automatic Discharge Fire-Boy-Xintex Clean Agent FE-241 MA-2 Extinguishers. And the CruzPro GD-25, Gasoline Vapor Detector and Alarm.
