Just had my Baystar steering put in matched with Yam100 4 stroke.
The Baystar being for under 150hp
Seastar for above 150hp
Even the Baystar helms come in different specifications. I had the Baystar plus, just an improvement in the bearings over the standard Baystar helm.
I wouldn't be surprised if the Baytstar helm that you have couldn't just be swapped for a Seastar helm. Whether the hoses/tubes are compatible with each unit........would need to ask, but this brochure seems to think they are.
Whether the engine rams are totally different, but could only guess that either is up to the job, just one is perhaps more inclined to hard commercial use.
Shame to give the boat back just for the steering.
