Hello, my name is***** you for allowing me to assist you today.
The piece looks like rub rail.

Expert:  Charles replied 1 year ago.
Thanks,
Have you done a compression and spark test on the engine yet?
What is the max clearance between the pump impeller and the wear ring?
Customer: replied 1 year ago.
Less than a 1/16 of a inch and no I haven't done a compression test what should it be on this engine
Expert:  Charles replied 1 year ago.
The max for the impeller is 0.040"
the compression should be more than 90 and close to each other. No more than 15% between the cylinders.
After you installed the new throttle cable, did you make sure that the carbs are still opening all the way?
Customer: replied 1 year ago.
Okay I will do a compression test on it and yes I adjusted the cable so I would get full throttle . The boat starts fine when in netrual out of the water turns about 4000 Rpms and when in gears it will turn overs 5500rpms no bogging or anything like that
Expert:  Charles replied 1 year ago.
That is out of the water right?

Got it,
How fast will the boat run with out the tube behind it?
Customer: replied 1 year ago.
Same it does not make a difference
Expert:  Charles replied 1 year ago.
Really,
That is sounding more like a jet issue. Can you measure the distance from the impeller to the wear ring using a feel er gauge?
