They look similar but I have not yet removed the starter from the 650 yetAfter you answer alldodge's question, are the mounting holes the same pattern?
An81 50hp MercWelcome
What motor is the starter used on?
I appreciate your help and all others thank youThanks
Merc part 50-65436 and 50-44369A1 and 50-73521 and a few others are all supersceded part numbers, so there should be no issues
