Bogging down at higher RPM's

[dvan1901]

I have a 1993 Larson All American 190 with a Yamaha 4.3 V6 in it. I took it out the other day and it ran great up to about 4,000 RPM, but when I would go to open it up to about 4,400-4,500 RPM's it would bog and lurch. The built-in overrev doesn't kick in until about 5,200 RPM's. It was the first time is was ran wide open all year, but I was thinking of putting some fuel cleaner in it and checking the plugs. Is there anything else I should pay attention to at this point, or just see where this gets me?
