Guest, we are pleased to announce that Hydrophase Ridesteady is offering an extra $50 off for JETBOATERS.NET members on any Ridesteady for Yamaha Speed Control system purchased through Sunday, February 14, 2021. Ridesteady is a speed control system (“cruise control”) that uses GPS satellites or engine RPM to keep your boat at the set speed you choose. On twin engine boats, it will also automatically synchronize your engines.
Mounting hardware would be the same stuff a I/O small block Merc would use, I believe. Major hurdle is gonna be mating the engine to the drive. The bell housing bolt patterns are completely different and the crank flange bolt pattern is different. As you didn't list the year or the make of the drive you are mating to, thats about all the immediate info I can give you.
