Was working fine and was dialed in pretty well then it seemed like it was running out of fuel when comming off a turn and powering up.
Thought it might be loosing tank pressure so I checked all the lines and tank but found no problems.

The pickup is at the correct end so during exceleration the fuel goes to the pickup.

I installed a new tank stopper and brass or copper line whatever comes in the kit and i'll try it again tomorrow night.

Anyone experience similar problems and what was the cure.

Ron and boatdoc thanks for the earlier help.
The props were 230 and 235 prather.
what other props would work for this boat/motor config.

It might be a little lean or the prop too low in the water. The 7.5's seem to want to lean out as they start to build up heat in them after a few minutes.
Other props to mess with would be the Octura X-646/3, X- or M-447, X-448 or X-450 in both 2 and 3-blade versions.
