This Upgrade Changes Everything!
Picking up the hook and moving on is always a bittersweet moment. But alas, summer doesn’t last forever and neither does our visa. Aotea is but one glorious piece of this sweet kiwi pie.
“All we have to decide is what to do with the time that is given us.” — Gandalf.
But, thanks to one powerful new upgrade, firing up the engines to pick up the anchor is way more exciting! We have sooo much more power and Jason is pumped to tell you all about it.
So, we say goodbye to the barrier and set sail for the wilds of the city. Our new sails are waiting for us (whoop whoop) and a few more exciting new upgrades. Because this is #BoatLife and the projects never end.
We’ve been using this system since mid-December 2021 and it’s now June 2022. So we’re 6 months in and it’s worked well. The ability to pump in so much power to our battery bank while simply arriving at and leaving an anchorage is fantastic! We think high output alternators will be the norm on boats vs a generator in the future. It’s already becoming an option with some boat manufacturers and that is very cool to see. Our new CURIOSITY2 hybrid-electric system is set up with high output alternators as a part of the eco-drive package. Different alternator manufacture, but same idea.
FYI, we were warned by friends with high output alternators that we would notice a slight drop in our overall speed. That’s because power is being diverted to the batteries. For our setup, it seems to be about half a knot or so. For instance, if we motored with one engine at 1800 RPMs before we would travel at about 5 knots, now it’s 4.5 knots.
The team has been responsive to my questions, concerns, and feedback through the installation, setup, and use. I’ve also spoken with Rob one of the lead engineers who helped me troubleshoot my wiring schematic and install. There were a few bugs in the beginning with our setup (ours is a preproduction model. So I did sign up to be the guinea pig), but the techs at Electromaax helped us sort out most of it. One of the issues was the alternator heat (they do get hot, as expected) was setting off an alarm on our starter battery (because it’s located close to the alternator). We added some extra engine insulation around the battery and that solved the issue. The only remaining bug is our tachometers haven’t worked properly since the installation but we can see our RPMs by plugging our computer into the system. We’re still not sure what caused the problem but once we figure it out, we’ll update it here.
Everything was surprisingly ‘plug and play’ for the most part. Even the exact wiring guide for our catamaran (with 2 Yanmar 39s) was sent before we installed it. If you have a good understanding of 12v wiring, and the tools to do the installation, you could probably do it yourself. I personally don’t own proper big boy wire cutters or hydraulic crimpers for such thick cables, so I knew right away it was best to hire a pro.
Even if you don’t go for the High Output Alternators I would highly recommend the Serpentine Pulley kit and Belt Tensioner. For our Yanmar 39s, it loves to eat through the v-belts and they’re such a pain to replace. If you’re dealing with the same dusty issues we’ve been struggling with for the past 6 years, you will think this is the best thing since sliced bread!
We have talked with friends who have the Mastervolt, Balmar, or earlier versions of the Electromaxx high-output alternators who are very happy with their set up too. So lots of options out there to research.
Full Disclosure: ElectroMaax reached out to us when they launched the new Genmaxx 2 and we really liked the updates they had made which is why we were keen to test them out. They sent the product, we did the installation and they offered a discount to you and a referral fee for us if you use the discount code below.
No matter which brand you choose, we’re fans of the technology and think high-output alternators are a fantastic solution for boaters.
