Thanks for your not helpful at all response! He also has no idea what to get, so this post is actually to help him as well haha. So, I’m not really sure what this response was meant to do.
The response was meant to let your husband make the appropriate choice, since if he had the boat I assumed he was a boater.
My apologies for trying to help with no other agenda in mind.
Bass trackers are still in business. If you have a Bass Pro or Cabelas in the neighborhood, take the boat there and they will show you what you need. If not, they are on the internet.
Regardless, you have a 25 year old boat so possibly it's a maintenance issue. It could be a simple problem that can be corrected by some lube in the proper place. A marine mechanic may be an alternate option first.
If the steering issue is simply because he installed a new motor, then we probably cannot help you. You need a marine dealer who can see the issue in person to assist
