I am new to the boating and need some help please..
I have a 83 34' scarab with twin 502's and trs outdrives. I just bought the boat from a trustworthy friend and when we pulled it out of storage we realized that one of the outdrives had a busted lower case. I have not figured out the problem yet but am looking for another unit so I can get in the water.. Can anyone help me on what I need to know... Alls I have come up with is its a LH rotation with a 1 1/16" prop-shaft bolt. The sticker on the top of the drive says "500" I have seen some online say "330" can someone please help me on what I need to get
Thankyou

There also should be a metal plate/tag on top of the trans that tells you if its a borg warner. Red tags were 71C, and Green tags were 72c. My guess, in a 1983 scarab, prob green tag borg warners......they are the good ones..

The drive shaft is different on a Merc trans compaired to the BW.BW has a shaft with external splines and a Merc trans uses a shaft with internal splines and a spring on the end.
