Author Topic:   Winter Project: Helm Electronics Upgrade and Relocation

Over the last couple of seasons I decided to simplify and upgrade my helm area. My thought process included researching and deciding what to add--that was not an easy task because there are so many great new products on the market--while using the space allocated in my Whaler's electronic box. I looked at and laid my hands on all the new units, and finally narrowed my choice down to the Simrad NSS 7 and Raymarine E7d. After taking a look at all the features, functionalities, and displays each unit offered I decided on the NSS 7. The E7d is a terrific unit but the NSS 7 just suited my needs. I planned to keep my Garmin 740 as my primary navigation and weather unit and the NSS 7 as my SONAR and backup navigaton unit.

Just before I ordered the NSS 7 I went back on the boat for one more evaluation of the mounting space I had to work with and much to delight determined I could squeeze an NSS 8 in.

As I rewire and move to commissioning I will post more pictures. A big thanks to Jim at BOE as usual he came thru an offer I couldn't refuse and as always a pleasure to do business with. You have questions Jim and his staff have the answers.

Here's some pictures of the project.

Happy New Year to everyone!

Tom--That's excellent work. Your helm has been uncluttered with no loss of functionality. Looks great, too!--Butch

Blue: Why did you go with a Simrad unit instead of another Garmin? Do not get me wrong. I think that a Simrad is a high-end unit, and I was just wondering why. Would think that purchasing another Garmin you could [connect] the units so they could talk to each other.

Where did the Standard-Horizon radio end up? I don't see it in the "after" pictures.

You'll see a label in one of the pictures SH GX2100. If you look closey you'll see a gimble mount. I haven't mounted the radio. I yet have a lot of wire to route.--Tom

Worked on the Garmin and SH GX2100 wiring this afternoon. I'm lucky as I can do a lot of the wiring off the boat.

Looks great. I'd love to hear your impressions on the two units after using them side by side.

I really like the look of your NMEA connections.

Have two systems sharing data via N2k network still refining that.

Will post some pictures later.

Tom, it looks like the panel your chartplotters are mounted to is wood. If it is, how it that working for you what is the finish on it? If not, what is it? It looks good.

I see only three NMEA 2000 tee's, I would assume you have both the Garmin and the Simrad connected plus one for power, so how is your satellite weather connected?

Yes, the dash panel is wood. I used a piece of 1/2-inch oak and spray painted it with three coasts of paint. I prefer wood over KING Starboard. My last installation using wood was in place for five years.

I have one Simrad cable that has an adapter plug so it can connect into the Garmin [wiring devices on the] NMEA-2000 network. I am waiting on one more cable and two more Garmin Network T-fittings.

You always inspire me. I have the same glovebox and I need to update my GPS unit.

If you changed fish finders, did you have to also change out the transducer on the transom? It would be nice to see pictures of that install too.

I have to change to a different Airmar P66. The current on is an Xducer ID and the Simrad can't use it. Nothing to changing it out I have a Stern Mate transducer mount so all I have to do is remove 4 allen screws and then install the new P-66.

About 95% complete finished the underneath wiring today. Here are some more pictures.

I had to raise the SH GX2100 two inches off the mounting surface so I could get the N2k network connectors installed.

Last report .....

I swapped out the old Airmar P66 transducer I used with my Furuno 620 and intalled the new one for the Simrad. The good thing is I have a SternMate tranducer mounting system so it was a matter of removing four set screws holding the SM mount to the back plate on the transom then removing 3 bolts and nuts holding the P66 to the SM. Process took all of 15 minutes and I had the old one off and the new one on the transom. Took me about half an hour to route the new P66 cable to the Simrad.

Some pictures ......

The P66 angle looks steeped than it really is the fron of the Whaler is jacked up so as to let the water run to the stern. Two%20of%20a%20Kind%20Electronics%20Box%20Redesign/117.jpg?t=1326057999

Post install ......

The NSS 8 install was very easy to do. Documentation was straight forward as was the connectivity (NMEA 0183/N2k). Only thing left for me is waiting for a Nk2 cable that has an adapter to connect the NSS 8 to my Garmin N2k backbone.

Wiring the NMEA 0183 connections between my ICOM 504A tand NSS 8 was simple. Simrad did a very good job laying it all out. Two%20of%20a%20Kind%20Electronics%20Box%20Redesign/111-1-1. jpg?t=1326293821

I'll do some video comparisons of the Simrad NSS 8 and Garmin 740. It's been very interesting having the two units side by side comparing displays and functionalities.
