does any e23 7 series have that master cylinder or just the 750il? i didnt know the e23 came in a 750il. they are the 1977-1987 7 series. did you mean to say the E32, which was from 1988-1994 or so?

oops,
88 to 94, some 740's have them too.
very easy to tell by the orientation of mounting bolts, e30's and this bigger MC's are the only ones with parallel mounting pattern.

well put, that's a slick auto-x setup, and should be fine for an IX with a waverunner. 17ft boat behind an e30 --- rediculous. Buy a beatup pickup.

My car was used to tow a 17 foot boat for a little while until my dad got his truck. No problem.
