View Full Version : Outboard length

03-07-2011, 10:37 AM
Will a 20" Johnson outboard work for a Donzi F 23 transom? I know how to measure to prop, but has anyone run a pair of short shaft 20" motors? Any issues?
Thanks.......all ideas appreciated! :)

Don't be discouraged if your answers are not plentiful. The vast majority of people on this site run I/Os, not outboards. Also, not too many with that boat.

pretty sure you need a 25"

Appreciate the replys..........was wondering if anyone out there? Good point on the I/O's.......did not consider that issue. :cool:

I know its not the same boat but my 23 Seacraft used a 25

Sounds to me like that would be a 25 for sure. A 20 is a very
short shaft length. My maritime skiff uses a 20. It has 12 degree
dedrise hull. Almost flat. I would think the F23 has a much
sharper V hull than that

I did some measuring and 25" is necessary. 20" would be too short, even in a dual setup. Thanks for the replys!
