Author	Topic:   Shaft length for 1974 Revenge
j244466	posted 08-26-2011 03:27 PM ET (US)         I'm confused about 20" v 25" shaft length. What is the appropriate length for a 74 Revenge?
Tom W Clark	posted 08-26-2011 03:58 PM ET (US)             It is not confusing at all, 20" is what you need. By the way, you might want to mention which 1974 Revenge you have. There were more two, 19' and 21', though they both used 20" shaft length motors.

For twins, a 20" engine has to be installed all the way up in the fifth bolt hole, as shown here: http://smg.photobucket.com/albums/v429/lgoltz/Outrage%2021/?action=view& current=Scan_Pic0015.jpg A higher HP single can be installed in the 3rd bolt holes, if higher performance prop is used.
