News flash, Alternator testing and sail delivery.

Two big arrivals today on Letitgo, one with no stress and one with just a little more spice but all have to do with power.

We received our asymmetrical spinnaker from voyager sail, first of all I would like to thanks Dale. During the entire process, his communication was perfect answered all question in detail and on time. He followed up during the production and delivery schedule. Respecting all his promises, looking back it took 16 e-mails and two phone calls, from first contact to delivery one month, in my book not bad.

We took it out of the box but had no time to play with it. We were chained to a project yesterday; sorry couldn’t resist the bad joke. We just took a glance, it looks good and *V*’s first observation was : the sail bag looks well finished inside and out, a good sign! She is the sail expert on board, ( editor’s note : no not quite….) all we need to do now is recruiting Rae  to get out and see for the rest of the equation. How does it fly?


The second one is the arrival of the alternators from Electromaax, well packaged and looks well built to my amateur eyes. But with a suspicious cloud on top of them following the last few days event.



I knew where to go, so decided to make a run for the closer shop with a bench test. Not a fancy shop, but the owner seems to have seen a few devices in his career. Well what was the result?


On start up, once he turned a knob we saw 80 Amp at 1800 rpm  he let it run for five minutes and we saw a decline but nothing under 75 Amp. I didn’t want to abuse his generosity and ask him his opinion. In a strong accent, his answer was simple “It’s all good, somebody knows how to built this thing”. Thank you sir and free of charge, if the sign would have said marine on it, I am sure it would have cost me $$$$.


So it seemed to confirm the original report that came with the unit. Max 120 Amp output, at 2000 rpm 73 Amp and 5000 rpm 116amp but that last one we hope to never achieve it on the boat.

Now the real test, will be coming in the next few weeks when I mount them on the boat. I will review the document for wiring, I will not hide you, that I am a little worried for that part and then we will benchmark with the Hitachi. My idea would be to keep an old one on one engine and install a new on one the other, run both at the same RPM and take measurement. Let me know if that is a good idea or not.

Seattle boat show this week end, see you all out there!

    Well, what will you use the info for ? you know what the old once gives you today,
    put on the new once and keep the old once as spear. and you will get the diff then.
    Just make sure they get plenty of cold air, when running hard.
    and a lot of nice pictures as you put them in 🙂

  2. The info is to verify that the manufacturer claim on his product are correct. Some user, say they had a problem we them. So far so good with our test, but the real on is the live situation. Of course the Hitachi are my spare and not to worry the install will be documented so I remember LOL
