My wife and I bought a 2012 Cutwater 28 last year, and I am still getting familiar with all the equipment reading all the manuals. I don't have an operational manual for the generator.

My wife wants me to run the generator while at sea to have an air conditioned cabin but I'm unfamilliar with operating generators - my skills lie elsewhere but I want to learn.

Does anyone know where I can get an operational manual or a step-by-step guide on how to run the generator?

Thanks,
Mr. Non-mechanical (aka Paul)
 
We have a 2.7. Mase. Our control panel for the generator on a R 27 is just below the air conditioning controller to the left of the helm area. Hit the on button on the generator after you have checked the oil in the unit. The numbers on the generator panel will change to the hours and then you press the start and wala you have power. I would be careful about continuous cranking if the generator fails to start as the exhaust is what forces water thru the water muffler. Without any exhaust you can cause issues. Hit the off button to shut it off. I would be careful about running too many items at the same time to avoid any overload issues. Heavy amperage draw items include the microwave, coffee pot, hair driers etc. You have to have the boat in the water as they are water cooled at least ours is. There is a switch up in our helm area that allows you to switch between shore power, generator or invertor. Switch to generator your AC meter should show about 120 volts. Turn on the air conditioner and keep the speed down as if you go too fast (above about 12mph) the A.C. units pick up not be able to pull water and will lose it's prime and shut off.

Paul, we too just got a C28 with the same generator. Just a word of caution about running the generator while underway. During our sea trial, we ran the generator and it seemed to operate well at some speeds but I was not paying close attention since I made an assumption that a generator installed on a C28 should operate it when you want to use it. That may not actually be the case.

You have been appropriately cautioned against using high load items at the same time. In fact, operating the AC, the stove top, and the oven will probably not work. The good news is, most of us don't cook and bake on board while in the generator.

I have discovered that, while running even at idle, my generator shuts down with an error code indicating that the generator is overheating. Obviously, I'm either having a cooling water supply issue or something more central to the generator. There has been much written here about the design of the cooling water pick-up thru hull and that we need to realize that higher speeds (over 10 mph) may negatively affect the ability of the generator to appropriately acquire cooling water.

I'm still trying to figure out what my generator can support while underway before I scream for help. I'm very concerned about the capability of this little generator while underway. We live in FL and it's a bit warmer down here than in the Chesapeake Bay and out water temp is 88F today. So far, I'm disappointed with the load capacity and the ability to run the AC at any speed. I'm going to have my diver double check my generator thru hull.

I'll post progress of failures here. I plan to check out my boat's performance this Saturday unless the building tropical storm gets here early.

Be careful and check that your hot water heater is hot on when other high draw items are needed.
 
Well, I checked out the generator while on the move and it shut off after about 10 minutes. I had the AC on, but nothing else. Next test will be to verify water circulation at the dock and then underway. In addition, my diver will need to check the intake for obstruction.
 
Talked to the factory rep in I think in Tampa about the over heating. He solved it by having me remove the sound dreading panel on the aft cover, no change in noise level. Apparently this sound deading restricts the air flow just enough to shut down the generator.
 
Just a note that there are two fuses buried low on the left side of the unit that you might want to be aware of. I had one blow early on, and it took me a while to figure out that it existed (using the schematic), and a bit of finger damage trying to get to it.
 
Read on here were a gent would just use a 2KW Honda or Yamaha Generator on the swim platform.

While not quite as integrated, not a bad option for some situations.
