C28 Manual and Wiring/Plumbing Schematics?

[GulfSailor]

I appreciate that a manual doesn't get written overnight, but the wiring and plumbing schematics should already exist in one form or another at the factory for use in building the boat, and it would be very helpful if copies of those were available.
For instance,while many of the individual wires are clearly marked, there remain quite a few unlabeled 'mystery' circuits.

Is there any indication of when the manual, and more importantly the schematics might appear?

Thanks.

Thanks for requesting wiring and plumbing schematics. I will be working with our electrical provider to get the cutwater wiring schematics here soon. I will also be working on the manuals for the cutwater towards the end of this year which will have your plumbing schematics and so fourth. In the meantime, Ronnie,Kenny and myself are all here to help you with anything you might need on your new boat. Please dont hesitate to contact us at anytime and we will be happy to help you figure out your these mystery circuits you are talking about.

Thanks Andrew, I'll get some pics to you in the next couple of days.

Has there been any progress on this?

As one who has a new Cutwater 28 on order, I cannot second this very reasonable request strongly enough. I am looking forward to having a boat where I can actually understand the systems. (My other boat was built in 1966 and fixing anything is an exercise in archeology).

Please devote some resources to producing some documentation that matches the quality of your very fine boats!

Many thanks,

steve

sdubnoff: Welcome to the site!

What we are asking for may not exist I fear - not sure to what degree these craft are standardized. Still doesn't hurt to ask though.

We are happy to help with any schematics you need. I provided (4) cell phone numbers to each one of the customer service team that can assist with any questions you may have. I have a manual written but it is not finalized. How about some wiring schematics to start?

Cutwater customer service again proves itself second to none!!!

It is 2020 and I have not been able to get the wiring diagrams for my 2018 Cutwater 28. Not sure why the factory will not provide them but it is very discouraging.

Gary, unfortunately the illustrated wiring and plumbing schematics are of fuse panels, breaker panels, and location of the equipment. Then it states:
See charger/Inverter schematics for wire sizes and fuse size.
Sees engine schematics
See thruster schematic
for fuse sizes.

The best way to understand and troubleshoot an electrical or plumbing issue is just dig in and trace it. I have followed and traced every 120AC wire in my boat to confirm it was connected properly and tight. I have found some discrepancies and loose connections while doing so. I found the main 120V ac from shore power plug to ELCI to rotary switch to be 12ga boat cable. It should be 10ga. The 12 ga theoretically will handle 30 amps but some of that current doesn't go thru the 30 amp panel breaker as the panel is wired. The microwave /convection oven and outlets only have the neutral protected. If the incoming shore power has a load over 30 amps which is marginal for 12ga boat cable the only protection is the ELCI breaker. I highly recommend that if you are a DIY boat owner. Trace and inspect each 120V ac circuit for tight connections proper location of hot and neutral, confirm a good safety ground. Inspect boat cable size to match load. The 12 V side is easier to trace because of the labeled wiring. I confirmed that the right fuses were installed in the right place. in doing so I found several fuses installed for circuits not in use and the wires were terminated with an open butt connector or just cut. Example the down riggers wires ( down riggers never installed) were cut and left exposed under the gunnel protected with 40 fuses but (hot), the macerator pump ( I don't have one installed from factory) wires cut left exposed in the engine compartment with a fuse in (hot). I have a feeling that the electrical system is not installed by an ABYC certified electrician. He/she installs the electrical system by design and doesn't really know the electrical codes. A wire is a wire and a the design says put this size fuse here. I'm sure there is an employee that is a representative of the ABYC and is certified that says the boat meets the standards in general. If everything works fine its probably ok. As the boat owner if there are any descripencies check the electrical system out completely or have ABYC trained certified electrician inspect it. There is a difference in residential codes and ABYC electrical codes This is not to say residential electricians are not well trained and skilled electricians it just means there are different rules on boats. Good luck in troubleshooting you systems hopefully Fluid motion can shed some light into what issues you are having.
