Keith,
Next time out can you pull the load and speed numbers for: 1750, 1850, 2000rpm. I just want to see if they are roughly the same. My boat has a diver on it monthly so bottom is always clean.

Yep. I will check it this weekend for you......with a beer in hand and smile on my face.

Can anyone tell me where the AC raw water cooling pump relay/trigger is located? The guest cabin AC unit will not turn on the cooling pump. The master unit and the salon unit both turn on the pump, but the guest cabin unit will not. I've confirmed that I have voltage coming out of the Cruisair control box to the relay, but I can't find the relay/trigger. Thanks!

Update: I found the trigger relay. It is aft of the washer/dryer under the athwartships bunk. It's a Cruisair 3 station pump relay W/3-TR230 triggers Model PR3X-3C. Now to continue troubleshooting...

Second update: The trigger was bad. Replacement was $50 plus shipping from Citimarinestore.com. Bought two so I have a spare when the next one fails. Had to take the bunk supports off and prop up the bunk to do the work. Any day you can fix a boat problem for $50 is a great day!

Mike,

Here is a link to West Marine and a Garmin NMEA starter kit. You need to create a "Backbone" which is nothing more than a cable with connectors. The "backbone" must have power (Yellow cable) and simply plugs in and you twist the cover to lock it in position. Then connect a black cable from a connector to your device (anything from a gauge to a chartplotter, Fusion radio, VHF radio etc). Take another cable and plug it into your Maretron sensor and a connector.

That's the basics of setting up a NMEA2000 system. The devices will find each other and talk to one another automatically.

I put in a NMEA2000 system in my 340DA. Hooked up a Fusion entertainment radio, a Garmin chartplotter and VHF. Turned them on and they worked. The radio got map co-ordinates for the Emergency button and the chartplotter could operate the Fusion from the helm.

Steve,
I think I might already have the NMEA 2000 hardware installed on my boat. The PO upgraded much of the electronics prior to my purchase of the boat, to include new Garmin chartplotter, Garmin radar, Autopilot, VHF radio, and more. I know the tech who did the installs and I'll bet he tells me that the NMEA 2000 is already there. I might just get lucky! I'll let you know.

1755 RPM—-load 65
1859 RPM—-load 71
2004 RPM—-load 84

It was a windy day and I was heading into the wind, which may affect it slightly. I was 9.5/10 fuel and full water with four people on board.

Thanks Keith, this past weekend I was running 1750 at 20-21mph and my load was 72%. My guess is I need some pitch removed, does that sound correct?

My mechanic just got my port engine put back together after digging into the dreaded manifold leak. What I assumed was just the standard leak turned out to be a blown out gasket on #6 which was puffing soot back behind everything. We machined the manifold at my shop and my mechanic did the aftercoolers, heat exchangers, replaced hoses, replaced the coolant circulation pump and we also replaced the turbo. It was put back together using the latest service bulletin and spacer recommendations.

We sea trialed on Saturday with 3/4 fuel, 6 adults and 5 kids, no dinghy. I had one cup # removed over the winter and am very happy with my numbers.

2000 RPM
38 GPH
62% load
930 EGT
20.5 knots

Going to watch to make sure the leak doesn't reoccur then will do the STBD side next winter.

I think I have the same problem, I realized I am getting soot on the aft top end of the port motor. What am I in for?! Did you pull your floor? That’s something I do not want to do. It appears it’s leaking towards the rear at the exhaust manifold/cylinder junction. First problem is finding a mechanic down here - two days labor?

 

[quality time]

I'm not familiar with the CAT set up Russ but I did not have to pull the floor for the PORT engine repair on my QSM. I will for the STBD side next winter though. I also haven't gotten a bill yet but my mechanic is a good friend so I don't expect any surprises. He probably had 3 days on and off over a 2 week period.

 

[Russ Calasant]

Thank you, good luck

Hey Keith, can you get me some additional numbers? At those cruise speeds (1750, 1850,2000) can you get your mph/kts. Thanks

Ok, am I the only one who's starboard tank vent is blowing some fuel the WHOLE time I am fueling up. I have to run the pump so slow compared to port. I'm debating running a new vent line and trying to figure out how to increase the angle so it's more uphill.

Mine will blow fuel but only when it’s completely full. Not sure what is causing your issue.

You must have some type of obstruction in the fill line or at the tank. Follow the lines from the fill hole to the tank and see if you can detect an issue. I am not sure if you can even see those lines.....and I am not at the boat to check for you. Other than that, I have no idea why you are getting back flow out the vent line. You may want to post your question on the Ask the Captains forum and see what they say. Those guys are REALLY good.

Has it always done this or a new thing? My guess is that there's a low spot that held some fuel from overfilling since the vent is on the Port side. That's a lot longer run to the STBD tank.

Steve, I checked with the electronics guy who did the upgrades on my boat for the PO, and I do have NMEA 2000 on my boat. All of the installs were done in summer 2019. Most of the electronics are Garmin, 8612 Chartplotter, Garmin 8412 Chartplotter/Radar, Garmin autopilot, Garmin VHF radio, and underwater lights that are connected to the chartplotter.

Having said all that, can you tell me if I get the Maretron device you mentioned, will it connect to the chartplotter? Can I connect it to a separate gauge? If so, can you recommend one? Will the link you sent for West Marine give me everything I need to install the probes into the exhaust and tell me where to install them? I know these sound like rookie questions, but I am new to dry exhaust and I don't want to screw it up.

I had this problem with a SR 450 I owned. Fuel would come out the fill hole until I got about 50 gallions of fuel in, and then it was OK. It took forever to get that first 50 gallons in. Turns out, the vent hose for that tank was dipped down, instead of being bowed at the top. Fuel would settle in the dip of the vent hose and not allow air to escape as it was displaced by the incoming fuel. Once we repositioned the vent hose, problem solved. Good luck.

Once we repositioned the vent hose with a bow at the top, problem solved. Good luck.

Mike,
I am not that familiar with the Maretron devices or your engines. You might want to call Maretron. In theory once you have the correct sensors you simply run a NMEA-2000 cable from the sensor to the NMEA Backbone that your installer put in with the other Garmin equipment. Once connected everything should talk to each other.

Thanks Steve.

If you have no intentions of doing future NMEA 2000 equipment I wouldn't bother just for EGT readings. I would just get a bundled analog kit like the one from SBMAR.com even though you will still need to run wires from the bridge to the engine room. I only went that route because I already had a NMEA backbone in the ER plus lots of other equipment on the network.

Hi QT, I checked with the electronics guy who did the upgrades on my boat for the PO, and I do have NMEA 2000 on my boat. All of the installs were done in summer 2019.

Having said all that, can you tell me if I get the Maretron device you mentioned, will it connect to the chartplotter? Can I connect it to a separate gauge? If so, can you recommend which gauge? Are there instructions with the Maretron that will guide me, and will it include the probes I need to install into the exhaust and tell me where to install them? I know these sound like rookie questions, but I am new to dry exhaust and I don't want to screw it up. Thanks in advance for your help.

Mike,
You would need to purchase a Maretron TMP100, two EGT probes, assorted NMEA cables/tees and a Maretron display (needed to set up the TMP100). I chose a Maretron DSM410 as my display that also replaced my depth sounder as it will display most any data on the NMEA 2000 network. Mine also scrolls engine data through Yachtdevice gateways. You can purchase probes from Maretron for ~$130 each or Amazon for ~$30 each... All in you will have around $800-900 in the project.

Instead, you may want to look into this Yachtdevices NMEA EGT sensor for around $300 total. I have no experience with them but am happy with my other Yachtdevices products and their support.

https://yachtdevicesus.com/products/exhaust-gas-sensor-ydgs-01?_pos=1&_sid=0f2101e14&_ss=r

The probes are installed just after the turbo in the threaded hole in the DeAngelo exhaust elbows. There will be a pipe plug in them now that you need to remove.
