Replace the steering fluid completely. How do I decide if I should have my helm rebuilt at the same time? http://www.boatsteer.com/index.html I'm also looking to upgrade my helm seat. Any suggestions? I'm thinking something like this. http://www.llebroc.com/product-p/4brtrw03-.htm We do some traveling, and the original seat just doesn't hack it after 4 to 6 hours at the helm.
