I was wondering if anyone could help me decide on Seastar Pro Or Baystar hydraulic steering system on a 1991 20' Aluminum Jetcraft with a 2005 150 horse Mercury Saltwater mounted on a offshore bracket?The Seastar cost twice as much.The Baystar I can order for a little over $500.00 dollars and is rated up to a 150 horse.Mine is an extra long shaft and seems like a lot motor.Any input would be appreciated.Thanks.
