Boat feels maxed out at 1500-1600 rpms

Hey everyone, so I just replaced the carb with a quick fuel 600, a née fuel pump and fuel filter/water separator. Boat starts every time in the driveway, but when I get it on the water it feel like the engine is maxed at 1500 rpms. Any ideas??

Also when in the driveway the port side exhaust seems to get much hotter than the other.. not sure if it’s because the pressure of the hose is not enough???

And final question. Promise:) the looking glass on the secondaries keeps filling up no matter how much I adjust the screw on the carb, anyone else have this issue?

Thank you in advance!

Joe

Keno,

I think it idles the best it has since I bought the boat, but I am sure it can be tuned better. I tried adjusting the secondary float this morning, thought I had it. But once I let it run for about 10min. They were full again.

I probably need to check the fuel pressure at some point?

Do you think the timing might be off? That is something I have no experience with if so..

I just don’t understand how it starts every time first try, Stays idling but when under load or in gear can’t get it above 1500 rpms.

Don’t know if that explains anything? Haha

Thank you so much

Joe

From his previous thread

Check to verify that when you open the throttle the carb actually is opening to wide open.  New carb just installed maybe your linkage is not right.
