2006 Yamaha T50 issue

[carolinaskiffman]

Hi I have a 2006 Yamaha T50, idles good, gets up on plane fine. 30sec to 1min after on plane in bogs down almost to shutting off. Will idle and go slow speed fine but wont get up on plane. I thought was over heating. I changed thermostat and waterpump impeller kit, same thing. Kinda stump. Any ideas?

Anyone got any thoughts?

What you describe sounds like a restricted fuel flow....maybe fuel tank venting not adequate, or bad fuel pump....check your vent and fuel flow hoses, fittings, pump, etc.

Thanks will give lines/vent a look. Just replaced the fuel inj pump recently.
