72 Evinrude 50 HP main jet?

[BowTieGuy]

I am having a lean misfire condition on acceleration around mid RPM. I was wondering if anyone has or knows where i can find a chart of what high speed jets/main jet I should be running. I am in the 3000-5000 feet elevation and currently have #58's in. I want to go a size or two bigger (richer). Also where can I buy these at? The local boat shop doesn't know where to get them.

You have to get them from an Evinrude dealer.
#58 is part number 308977 and is the stock jet for your motor
#59 is part number 319831
#60 is part number 315412

Living at sea level as I do, I don't know beans about adjusting for altitude.
