Is there an intake manifold gasket that works for the 525 EFI thats not from Mercury that can be bought through Summit or Jegs. I would just hate to blow all that money buying the ones form Mercury if theres a "normal" priced version that matches up.

mr gasket 121 should do the job.

Thanks Mike! That's about a 90% savings from Mercury prices!!

ya,mercury is proud of their parts for sure.
