I need to replace the valve springs on My 1994 500's.What would be a good reasonably priced spring ,retainer and locks set ?.................Gofast

I know that Merc is buying the springs from a aftermarket supplier. Proably crane. Or was it comp? Either way, I believe that you want to use the newer HP500efi spring. This spring helps resolve some of the earlier breakage problems.

Try the info Scott gave me in this thread!

HP 500 valve springs

Good Luck!!

I ended up finding the seat pressure was still too high with the new crane springs I have switched over to Comp Cams. If you need a Part # let me know and I will look it up. This info and recomendation came from my head builder. Scott

Scott , I was e-mailing comp-cams about springs and they mentioned part # 924-16 for a spring to use. Does that look like what your head builder would use?...............gofast
