Yamaha 3cyl 60hp two stroke

[Kymbo]

My motor will indeed all day long but as soon as I give it throttle it runs fine for about a minute then bogs down an will only idle let idle for a bit an then takes off fine butt bogs again

Inspect change fuel filters.----Test run with another tank and hose.

Also, check the fuel tank vent to be sure it’s open and allowing for free venting….

fuel pump or sucking air maybe
does it help to pump the primer bulb?

I'd do a compression test also. I know the evinrude/johnson motors would lose the center cyl often. I'm not sure about the yammies though if they had the same issue.
