    Official Cummins 6cta 450C thread

    We toasted our batteries this summer (an expensive adventure!) and in troubleshooting the root cause I did note that the grid heaters suck a lot of power when cycling. Was thinking of disconnecting the heaters as well, didn't realize there were fuses which could be pulled, where are they...

    I had this thought when putting it together - I looked for a 3-way valve so i could switch between. I didn't find one and for us, we are in fresh water so there is not an imperative to install one. If you choose to do so, let me know what valve you put in ... I can easily add one.

    I connected mine in 2020 and it has been working great. t Pump: I had a spare Jabsco pump (60psi, 4gpm) and mounted in in the ER beside the AC pump. It is mounted it on a board that bridged over the sump area; Plumbing: I tee'd into the AC line - I didn't add a valve (or check valve)...

    Hey Dean, I added one, for the exact reason you mentioned - not using our fresh water. Do you have a specific question?

    Hi Brian, the mixed use has its pros and cons for sure. The SeaRay wiring choices are not the ones I would have made and it can be frustrating. We have not had any problems for the past 4 years, it was only on this trip, one that required use of the bow thruster often AND having set up the...

    Thanks for the confirmation, Alex. Something I just hadn't anticipated but will be more careful next time.

    Check out https://www.sbmar.com/ to find the locations on your engines. Mine are the 6CTA and they had the diagram of where to put the two connections. I think I remember seeing the QSC on the page as well.

    Raymarine 4' Open Array & RL80C Pathfinder for sale

    Cleaning out the garage and forgot that I still have the radar and chartplotter. The last person interested didn't follow thru so bumping this up in the list. I'm not in the business of selling electronics - if you can use it, will sell them for $250 for the radar (including cable) and $200...

    We returned from a 7 week trip thru the Trent-Severn waterway - which consisted of 43 locks in one direction. We regularly did about 6 locks a day. During the locking process (in and out) I used the bow thruster so the Admiral could reach the lines and on exiting. After about 4 travel days...

    I added a loop off the engine to the hot water heater for the very reason you mention. We just returned from a 7 week cruise where we spent most of the time without shore power and this was one of those 'we are sure glad we added it' upgrades. We had hot water at the end of the travel day and...

    Had a foot or two of 'daylight' LED strip lights left from a home project that I added in the galley. Connected to the existing lights so they all come on at the same time - the brightness is materially different. The strip has an adhesive backing, easy enough to put up and you don't see the...

    The fuse is indeed the problem. I didn't think these would ever 'go' so was looking for a more complex problem. Mine have screw terminals - which I haven't been able to find. Do you remember where you sourced yours? Thks

    The engine sync pop-out fuse below the steering on the helm, is, well, popped out. It will not stay in when reset - even with no power on the circuit. There doesn't appear to be a short and I would have thought that with no power on the circuit it should be able to be reset. Any ideas on a...

    Can't help with any experience but I'm very interested how to lift the engine to replace the mount without punching a hole in the bottom. Will be following ...

    Surprising response from Sea Ray customer service

    This thread was helpful for me, so here is an update as of today's date. I was looking to reach technical support for a couple of build documents related to a electrical wiring diagram on my 2004 420 Sedan Bridge. 1. Called the support number at 865-971-6250: Was told there was nothing that...

    When I purchased the boat the centre mfd had already been replaced and you can see the adapter panel (it is actually a box with supports behind) - it was made by Tecnografic. When I changed the port side an adapter plate wouldn't have looked right (more on top and a sliver on the sides) so I...

    I added the same VHF last season for much of the same reasons you listed. I have mine tied into the N2K network and it will display the AIS targets on the MFD's. We might add AIS at some point but at least we can get those with AIS displayed. I did have some challenges with CPA alarm, would...

    I'm thinking that this is a good idea! Could either just let the hose hang loose and connect to the extractor when needed or plumb it into the Reverco line for the engine drain (with a valve on each line). As for the 'last bit', given the volume of oil (around a gallon) vs the residual in a...

    Hi Dean, nope! had my hands full getting the oil changed and ran out of time. I have the socket but I still have to grind down the chamfer as recommended. I've seen a comment somewhere on the forum that the fiberglass dam that is across that area needs to be ground down in order to get a...
