Thoughts on quality of SEI gaskets and bellows kits?

[CurrentObsession]

I am getting ready to order two new Alpha knock offs from SEI for my new to me boat. Will need shift kit, bellows kits, gaskets etc.

Wondering if anybody has good or bad results with these type of parts from them.

Gaskets would probably be safe, but I’ve read about problems with aftermarket bellows kits. I decided to go OEM when I did mine. It’s too much work to screw around with non-OEM stuff.

I’m sure the quality is fine, but I always use OEM parts.

Another vote for OEM here. I did the job alone last spring and it was challenging, no way I’d want to do it over anytime soon.

I have not used any of their stuff but in general I think OE is best for certain critical parts like a driveshaft bellows and impellers. Both can cost you a lot if they fail. The OMC Cobra/Volvo SX OE d/s bellows easily lasted 10 years on my boat....
