Loss of power
![kennydalglish](https://us.v-cdn.net/5020499/uploads/userpics/HBISADFOZETD/n6FVT8BJY5CR1.jpg)
Out yesterday running great for an hour or so. Then at about 4000 RPM's heard beeping and engine loss of power. So shut her down for 10 min. Started back up and cruised slowly at around 2000 RPM's ok but everytime I try to go above 3000 RPM's I hear the beeps again and loss of power.
During this time Engine temp (175 normal). Oil Pressure 60-65 (normal). Checked my oil. All good since I had just changed it a week ago. Checked prop to make sure there was nothing wrapped around it. All good.
Got back to dock and ran engine out of gear at 5000 RPM's all sounded normal with no beeps.
I have no idea what to check first ?? Any suggestions ?

Someone mentioned to change the Fuel Filter as a starting point ?
For some of them is there a way to unplug individual sensors to see if the beeps go away ? Ex. IAC etc.
I'd start with the raw water impeller, then check the heat exchanger for blockage (assuming the engine isn't raw-water cooled).
Anyway - if the fault only happens at high RPM, it's usually related to cooling.

Might be a newbie question but the boat is a year 2000 Rinker Captiva 232 w/Mag 350 MPI. Does that even have a gear oil reservoir ? I do see a power steering reservoir.
I have done a bit of research on the two beep alarm. I will start with the simple stuff first. Change Fuel filter, IAC valve (I am hoping I can unplug this and the beeps will go away) If so then I can drop the 100 bucks to replace it) If not I will move onto probably having my marina hook up their diagnostic tool to point me in the right direction. Thanks again for the suggestions.
I will keep everyone posted for future reference.
Aero yeah I thought that would be the case but tried it anyways. Speaking of there are a lot of plugs around the throttle body assy. I am not even sure which one is the IAC valve. The manual I have doesn't seem to be of any assistance.
YYRZ, Is this it ?? It is halfway between add and full so looks good. What fluid is recommended here ?
