Replacing our Generator, Bayliner 4788 Motor Yacht: Westerbeke to Northern Lights

446 ratings | 8493 views
After dealing with the 1999 Westerbeke 12.5 KW generator that came with our boat having continual brown out issues for months (and lots of diagnostics time) - we decided to replace it. We selected a Northern Lights 6 KW (1/2 the size physically and power, and about a 1/3 the energy use) which is an overall better fit for our power needs. This video goes over why we replaced our generator and then the removal of the old one, installation of the new one and installing a sound shield after that fact. Hopefully an enjoyable and educational ride :) Here's also our full blog post going over this project: http://www.technomadia.com/2018/08/boat-generator-upgrade-installing-a-northern-lights-m673l3-in-a-bayliner-4788/ ***************** Big huge thanks to AskCaptainChris.com for filming from the ground and for his excellent commentary.. and for Eddie the mechanic for welcoming us in sharing his work (East Coast Power Systems - Ft.

FYI, I read that the best boat crew would be 5ft tall, arms about 6 ft and super thin, two thumbs on each hand double jointed, and magnetic fingertips. Silent of course. Just saying, any aliens available?
Laurence Socrates (22 days ago)
That is an incredible video!!! I would have freaked watching that generator going out while the boat is moving at the same time. Wow. I do fail to understand why they didn't have the new generator ready to put back at the same lift out. It's not like haul out is cheap, and I"m sure they charged you both times :-((( I was just reading Nigel Calder yesterday who suggested that for most loads except AC, it was best and more $$$$ effective to use the inverter instead. I THINK that's what I understood. Id love to hear your input.
Laurence Socrates (22 days ago)
Not even consideting the usual delays, missing parts, etc, I get it. It's RV headaches, times 100. But the lure of the water, and the challenge, are more piwerful than reason...
Technomadia (22 days ago)
There was a lot of potential work to do between removal and installation to get the bay ready for the new genset (cleaning, new mount to be built, fittings, etc) ... they would have had to block us and keep us there while that was attended to (more costs, and no AC while on the hard). It was easier to return to our nearby slip and be in comfort... where we also had our living room remodeling going on too with our carpenter. Haul-out was cheap in comparison to the alternatives :)
Technomadia (22 days ago)
We have long given the same advice - it is silly to run a generator for small loads like charging a laptop or making coffee. As for why we needed to haul twice - we weren't certain how much time would be needed for any repairs or prep work once the old generator came out. Considering the cost of reserving the lift and crane, it didn't make any sense to keep them on standby for potentially hours.

Any chance of that blue oil line being cut from engine harmonics?
Technomadia (22 days ago)
There are no sharp edges touching any critical lines.

I just started watching your channel and love it! I as well have a Bayliner..mine is only a 21 footer but I love it. I live in the midwest and just boat in lakes but I dream of a big boat in crystal clear waters!

Very very very smart purchase!!! That 12.5 was WAY too big for your needs, and you are correct in saying that generators should be ran at load. 60% load is a good starting point. Personally, I would have gone with a similar size genny, and upgraded electrical loads. Led lights, efficient refers, 3M solar film on windows, etc is a better use for your money. Thanks for another great video.
Charlie Odom (1 month ago)
Technomadia great, thx. I just got through your launching video after the channel marker incident, so I'm way behind!
Technomadia (1 month ago)
Check our '1 Year Loopivesary' post back in April.. we shared all that then.

Technomadia I ran 28k worth of ac in a camper on 5kw, but i couldn't run the microwave at the same time, so I'm sure you'll run into something similar as you noted in the video. There really is no sense in running the oven, stove, 3 ac, etc all at the same time. I meant to ask what is your fuel consumption rate per hour while typical cruising and running the genset?
Technomadia (1 month ago)
Oh, we'll be doing all that too (already have all LED lights) - but cruising in the summer time as we will be - we do want the flexibility to comfortably run at least 2 ACs when needed.
jjaus (1 month ago)
Presumably the mountings to the boat in the old and new generators didn't line up? How did Eddie/you solve that?
jjaus (1 month ago)
Ah, thanks.
Technomadia (1 month ago)
We removed the original base plate after the old generator was out, and Eddie made a new one before the new generator was brought in. No biggie.

Glad the old Westerbeke generator lives on!

Love this video!
chris neville (1 month ago)
are yous going to use both wind and solar as backups to the gen set?
Technomadia (1 month ago)
Just solar
knowltek (1 month ago)
You should look into the motor starters caps on your A/C s an get the start load under control...being there 20 yrs old this might be or not a option...wynes had a nice video on the subject...have fun
Technomadia (1 month ago)
Yup, as we noted in the article that goes along with this video - that's in the plans.

I always watch but seldom comment but this video needs a comment --- It was amazing to watch the docking process and the removal and install of the new generator - I enjoyed it very much
mmanut (1 month ago)
Not to mention less weight. Just figured I’d throw that in. Good Luck, 👍 Vinny 🇺🇸

That was some BIG old generator!
Jamie Burke (1 month ago)
i think it is safe to say, the bus is less to maintain than the boat. YES
Technomadia (1 month ago)
For sure.. but boating is a whole new adventure for us. And we're loving it.

Impressed by the machinery!

Wow that thing is very quiet..

Nice Job! Great to see pros at work. Your generator job cost more than my whole 6 month sailing season budget -including the cost of my boat. However, I'm pretty minimalistic and won't have your level of comfort. Same views though. Love seeing the Bridge of Lions in the background. Keep up the good work!
Technomadia (1 month ago)
Indeed... same glorious views. Love that you can't put a price on those :)

Nice video. In our modern world electricity is a must have for almost everyone everywhere.
Richard Bohling Sr (1 month ago)
Change out looked well done and I'm sure you will be happy about your decision due to fuel savings and dependability. It sounds a lot quieter than the old one. It may not have been a good choice if you were planning to sell the boat, but since you plan to have it for a long time, I think you made the right choice. Happy sailing.
Technomadia (1 month ago)
We agree.. for our long term plans, we think it was the right choice.

Hey! I'm a new sub and find you guys very pleasant to listen too! I live in Washington State on an island in the San Juans, I'm just about to start school in the fall for marine technology. Looking forward to learning from your channel what it is like to live aboard a boat in this day and age. Great job of reveling cost, this is often overlooked by many.
Technomadia (1 month ago)
How awesome you're going into marine tech..that sounds exciting! Happy to have you aboard!

Good video. Good information. Great job by the mechanic and the Captain. It likes a good investment. Thanks
Mel Lowman (1 month ago)
Couple of questions. Not criticizing, I know you must of had reasons. I’m just curious as I plan to follow your footsteps in about a year or two. Didn’t look like you took an opportunity for a fast bottom inspection while hauled out? Why two haul out. Seems like would’ve put the removal off until the new generator and sound shield were on the dock and ready to go?
Technomadia (1 month ago)
And sound shield was back-ordered by more than a month... as we covered in the video.
Technomadia (1 month ago)
We actually did inspect during both haul outs (even did had a pressure wash) - and remember, we had just spent 5 weeks on the hard in Miami. Also, lots of prep in between to prepare the new generator for install - had to take out a lot of tubing, do some re-wiring, installed a new floor and do a lot of clean-up. Wasn't practical to do it in the yard - as it took several days.

As a resident of Vero Beach I know the Taylor Marine guys fairly well they are a rarity on the icw they are very helpful and are extremely honest oftentimes to a fault
Gt7 cuppels (1 month ago)
Technomadia you probably are correct I always thought that it was all owned by Taylor
Technomadia (1 month ago)
Crackerboys is right next door
Gt7 cuppels (1 month ago)
Technomadia looks like you were at Taylor as you went up Taylor Creek
Technomadia (1 month ago)
Is Taylor Marine a separate entity than Crackerboys? I had though they were different companies? We were at Crackerboys.

You know than owning a boat is having a hole in the water you pour money into!

Oh how I know that :) having had to feed both a 65 & 90C Hatteras I have a very close family member that makes my old 90C Hatteras tiny. It is nice to see someone that gets to enjoy it. I sold mine a few years ago, I still have a day boat but it is trailerable.
Technomadia (1 month ago)
We've found that BOAT is more accurately: Break Out Another Ten Thousand :)
sailinstyle (1 month ago)
Your verbal tabulation of costs is super confusing... "overall remove replace was $16K" includes what? Is that the sum of all the following items you list out? -thx
sailinstyle (1 month ago)
wow, new record for fastest reply! Thanks!
Technomadia (1 month ago)
Yes.. that's the summary of the costs that I then outlined.
captianjessie1 (1 month ago)
The lighter generator should also free up a little fuel milage distance per tank of cruising fuel

Crossing the bridge in St. Augustine and what do I see? Y not.
