I hear a lot about people breaking drives (I have too), but this weekend I blew a coupler. The boat was not sitting up all winter, sorry you northern guys. I was just wondering how many of you have had this problem. Thanks for the input.

I caught a bad one (wear) after I bought my boat.
The teeth were sharp instead of square.
Went with the stock replacement. (I am only 260 hp/side)

I've gone through a couple, no pun intended . Could be due to engine/drive alignment, high HP, or maybe bad gimble bearing.

Mine was due to bad alignment from the previous owner.

Mine was due to bad alignment from the (ex) engine installer

Mine was due to the previous owner NOT EVER charging the grease fittings.

I'll put this in the Technical Q&A section. Alot of folks lurk that section and could offer some assistance.

A Bravo coupler failure? Unheard of!!!!! Just kidding, probably #3 behind blown uppers and loose gimbal rings.
Very common, keep engine aligned and grease it and it will last somewhat longer.

I agree with gary, If you pull the drive once a year check alinment, grease the shaft , change the drive oil your problems will be far and few.
