"My first post here; my 4 year

"My first post here; my 4 year old Yamaha F25 just runs, with no hassles. But now I need to know the exact "shaft length" (short shaft).

Yes, I know, it's a nominal 16" or something, but I am building a boat to a very unusual design (W Atkin's "Rescue Minor", if you care) and am temporarily installing the outboard in such a way that this dimension is critical.

Unfortunately, I won't be near my F25 for a few weeks, and I forgot to get this measurement. Can anybody help me out?

I need the measurement from the top of the transom to the top (or bottom!) of the anti-ventilation plate.

Thank you

"Thanks - according to the man

"Thanks - according to the manual, "transom height" is 16.7" . but it slso says "Mount the engine so that the anticavitation (sic) plate is between the bottom of the boat and 25mm(1 in.) below it."

so that brings me back to - what is the actual measurement of the motor? I suppose I could guess 16"?
