Pete McCrary Posted June 3, 2017 Report Share Posted June 3, 2017 The new Suzuki 2.5 comes in both short (15") and long (20") shaft versions. Here's a photograph the long-shaft version: I've yet to know what the purpose is of the square rudder-like thing shown above the anti-cavitation plate. It seems to me that (for a transom-mounted OBM) it would prevent a reversing (180 degree) rotation UNLESS there is a motor bracket that extends substantially aft of the transom top edge. Even further for a transom with a negative tilt (like a CS20.3). I guess that wouldn't be required if it had a reversing gear? BTW, the short shaft version has the same feature. Does any forum member know anything about this feature of the new Suzuki 2.5 ?? Quote Link to comment Share on other sites More sharing options...
Don Silsbe Posted June 4, 2017 Report Share Posted June 4, 2017 I'm only guessing, but it might just be their way of turning a short shaft motor into a long shaft. Quote Link to comment Share on other sites More sharing options...
Steve W Posted June 5, 2017 Report Share Posted June 5, 2017 I'm dissaponted to find your Suzuki didn't work. I bought one, but I have a Honda 2hp long shaft as a fall back to use. I made sure it would also fit. Quote Link to comment Share on other sites More sharing options...
Chick Ludwig Posted June 5, 2017 Report Share Posted June 5, 2017 It is an insert that extends the length from 15" to 20". Too bad they don't make an actual 20" tow er housing. Quote Link to comment Share on other sites More sharing options...
Ken_Potts Posted June 5, 2017 Report Share Posted June 5, 2017 The Honda also has an extension to convert a short shaft into a long shaft. The Suzuki engine bracket (like the Honda) has an adjustable tilt. If you can't get enough tilt with the adjustment you can add a pad to the transom to adjust the motor angle so there won't be interference when you try to reverse. I don't think (and I'm prepared to be jumped on over this ) that the angle of the motor is incredibly important when we're putting along at four knots so why not adjust the tilt of the motor forward far enough to get rid of the problem?

Steve W Posted June 5, 2017 Report Share Posted June 5, 2017 Ken....I hope you are right because my setup has the motor tilted back just a bit. It should drive the stern down a bit in forward. I don't have a "mount" like Pete's. It relies on the clamp being opened fully and I have a spacer on the back of the transom to keep the motor back and still get 180 reversing. I hope it works. I bought it brand new. Quote Link to comment Share on other sites More sharing options...
