While you have your engine(s) out to replace or rebuild do you worry about replacing the coupler(s) between the flywheel and your outdrive?

HD all the way!
Cp performance has them also Marc at BAM.
Dual springs.

I would do it. It is not a good feeling for that to let go at 10 at night.

Only if it needs it.
Why replace a perfectly good coupler just for the sake of replacing it?

But if it does show questionable, then by all means. Standard for normal applications.

If you have one w/aluminum splines they should be replaced no matter what because they sometimes strip suddenly with no real warning,Smitty

jadento, do you still have your 27 Baja? Just curious.

If you have the opportunity to change the coupler out, I would go ahead and do so.

Been there... and although it did happen suddenly, I was running the piss out of it in some rough water the previous two hours of running time.

Sydwayz,
Nope, I sold it. I miss having my own boat alot, but I get out pretty much whenever I want on friends boats. Kinda nice not having a payment and still getting to be out there.

I did this last spring after I stripped one out, I replace both at the same time with the HD's and there is a huge diff. You won't go wrong getting the HD's!!!

I have heard the extra thickness/depth of the HD couplers spline makes engine to drive alignment even more crutial. I.E. if it isn't correct the splines wear worse or faster? Is this true?
