The one in the picture on the trailer is a 20" (long), which IMHO was too long for the application. I have since switched to a short (15"), which is what was on the transom in the picture with the boat in the water. By making the switch I actually gained a fraction higher speed (less drag).
Mercury's catalog indicates that they do not even offer an XL (25") in the single cylinder 3.5 HP 4-stroke model.
Would be nice to know the Model number of your motor.
Many manufacturers change their specifications from year to year so trying to find out what any particular years specification can be challenging.
Always best to post Factual information here so we can all be on the same page.
A short shaft apparently is good for your boat/situation as you mention for your Montauk 150.
It may not be good for other models like a Montauk 170 as Mjfnet states in his post where the 20 inch long shaft works for him.
Nice to have references for both newer model boats.
