rejetting evinrude 9.5

[Philip_G]

Does anyone have the jet sizes, stock and the part numbers for the smaller sizes for a 1970 9.5? I swear I've seen it before but can't for the life of me find them on the forum.
I need to go down about 7% in size.
Thanks!

The question begs to be asked---Why? Did somebody drill it out? The correct orifice is part number 309681 and it is a #48 (.048"). There should be no reason to deviate from that.

I live at 6500 feet and run the motor much higher than that. Local BRP service center advised 1% per 1000 feet in elevation, but I don't have the part numbers, the factory manual doesn't mention the stock size even. Guess I'd need around a .044 then

Re: rejetting evinrude 9.5

The origninal was 0309681 which was a .48 and is superseded by 0324020 which is a 49D. Early recommendations were for a 43D at 3,000 to 6,000 feet and 37D at 6,000 to 10,000 where 49D was used at sealevel.

43D is part # 0328539 NLA
37D is part # 0328537 NLA

38D is available, part# 0328525
