15 Horse Feul Problem?

[Nairn Martin]

Experiencing a problem with a 1992 15 horse Mercury. When running under load as revs rise over 50% bad miss occurs and boat slows right down. No problem at idle and slow speed.

A good place to start would be to check your fuel lines for any air leaks,it's possible that you may need to rebuild the fuel pump.
