rejetting carbs on a 1990 60 hp Johnson for high altitudes

[utfisherman]

does anyone know where and what jets do I need to put in my 1990 60 hp Johnson. I will be running at about 8900 feet elevations. and where can I get some. It doesn't run as good as it does at lower elevations.

Thanks

There should be specific jetting recommendations for your altitude. My old Mercury Service manual had them for each altitude, but the Johnson factory service manual I have now doesn't. They suggest changing the prop pitch for high altitude.

I did not see alternate jets for your carb. You might try to locate them, because if you cannot, your question is mute.

Best to change prop...

Talk to your local friendly boat shop.-----They likely have the list for the available jets.
