Twin 787 bogging down top end

[bellski]

Idles fine. When about mid to top end boggs down usually dies, will start right back up typically... had carbs rebuilt and that did not help at all... any advice is helpful.... in shop now putting new fuel pump on...

I have a 1995 speedster with the 657x engines im sorry but just realized something about your question
my engines have the fuel pumps on one carb on each engine and when I rebuilt the carbs the rebuild kits comes with the pump rebuild stuff

so you say you had carbs rebuilt that should have already did the pumps right
or you may have separated pumps on your boat sorry mines a 1995 it may be different

From what I have found they do have external pumps...

Get the new pumps installed and try it out. I think you will see a difference.

After you run it for a bit, pull the plugs and see if they are chocolate brown.
