2009 210 with the 6.0 in it, 150 hours. Starts up fine. When driving about 2000 rpm or lower it drives fine too. When I start to drive about 2500 rpm’s or higher, the motor will start to bog down. I can stop, restart the motor, and the same process can happen again. And again and again. I’ve replaced the fcc filter and inline filter, also did the plugs and wires. Is there a filter in the tank or something else I am forgetting? It seems like it is losing fuel pressure at higher rpm’s. I think the boat sat somewhere for several years with only150 hours on a 2009 model. I’ve added sta-bil to the tank for the past couple tanks of gas too. Ideas?

One of the fuel pumps would be my guess. Check fuel pressure at the fuel rail.

Are you sure it isn't going into limp mode? Is the Check Engine light on? 2,500 RPM is where limp mode will kick in if it is activated.
Have you drained the FCC bowl? It might have water in the gas, and I have had boats pull water in from the bowl at about that RPM.I own and operate Silver Cove Marine, which is an inboard boat restoration, service, and sales facility located in Mooresville, North Carolina.

I drained it when I changed the filter. I’ll drain it again and hook up a fuel pressure gauge. What is normal psi at idle and around 2500 rpm?
Sometimes it throws a code, and sometimes it doesn’t. Never stays on after turning the boat on and off. I wish I had a diacom still :/2009 Super Air Nautique 210 Team ZR-409

60 psi. Usually if a fuel pump is dying the boat will start but run poorly or just quit under load or higher rpms. But failing fuel pumps can present various ways.Originally posted by Boats Bros View Post
Check pressure with engine not running. After you press start the second time and the boat is ready to start, you should be able to hear the FCC spin up and pressure in the rail be good.
