C-Ranger Wiring

Charged batteries while cooling down the fridge with switch on #2.
Unplugged and kept the Fridge going: Readings in Volts

2:25 PM - 12.5

6:30 PM - 12.5

7:30 AM - 12.0

At the 7:30 AM reading, all electronics worked and fridge was still working.

Overnight temp was in the 50s.

Conclusion: We don't have to worry about the fridge running down the battery for an overnight cruise or an all day tow.

This has been a serious concern of mine.

Nice relief, hope this is useful.

Hi,
I'm a former C-Dory 25 owner and am about, I believe, to purchase a 2007 21 EC new here in upstate NY as a mate to my 53 Hatteras. I have a few concerns about the batteries getting so hot under the hood. Anybody have a thought about that? Maybe relocate them under the aft seat if needed?
Also, during a 4 hour test drive I could only get the rpms to 3050 max with two adults, two kids, half fuel, no water or waste. The factory says 3400. Does anybody truly see 3400rpm? I ran at 2800 to be safe but believe I should have cruised at 3000-3200, no? Many thanks in advance.

Andrew, My response may not totally apply since my tug is a 2006 21 just prior to the EC and I have the 20 HP instead of the 30 HP. Being in Florida my engine box is probably as hot as they get. Opening it while running I have not thought it to be that hot. In fact it is cooler that under the hood of my truck. I am not concerned with this issue but have also considered moving the batteries so I would have better access to my stuffing box. My fuel tank is there also and I have to pull the batteries and fuel tank to get to the stuffing box. Just inconvient with something that I would like to check. My first inboard and didnot know to check it after about 50 hours the first time. Lighting knocked out my battery charger so no bilge pump and I took on more water than I expected until I tightened it.
On the RPM I have had no problem turning 3400 but usually run about 2400 and burn very little fuel. Figure the small difference in speed is not worth the fuel burn.
The tugs are great and a lot of fun. My hardtop addition is a plus in the Fl. sun. (in album)
Wish you luck with the tug and have a great time.

Andrew,
I agree with Ron. Our Tugly is an '07 EC Tug '21 with the 30 HP. We normally cruise at about 2600 RPM. Depending on the load and conditions, that will give us from 6 to 8 MPH on the GPS. Fuel burn is as close to nothing as I can imagine. I can get her up to about 3200 RPM but she starts to squat and strain. Difference in speed is maybe 2 MPH from easy cruise to straining wide open. Prop may be a bit big but that is a great advantage at the slower speeds. We greatly enjoy the relaxed pace.
