A long shaft measures 22", if that helps.
I just checked mine again to be sure and it’s 17”. (It’s one of the current 4 stroke EFI models)I am having trouble finding a Suzuki short shaft motor to measure in my area. I would like to know the height from top of cavitation plate to top of the mount clamp(like where it rests on your transom).
The boat I'm rebuilding has an 18" transom and I'm wondering if I will have to use a setback to keep enough water on the foot to prevent cavitation and/or overheating.
Suzuki "recommends" a 15" transom but doesn't give the measurement from cav plate to clamp anywhere.
