Survey/ Generator who is 1800 and who is 3600RPM

Hello,

I'm interesting to make survey to know who have 1500 or 1800RPM generator and who have 3000 or 3600RPM and how many hours do you have on it.

Hugues

The new boat will have an 1800 rpm Northern lights 6kw generator.

I installed a 3600 rpm Fisher Panda 4200 Plus on our sailboat a couple of years ago. I know that people go into convulsions at the thought of Fischer Panda but I rather liked the little unit. It was nicely made, it had decent documentation with enough information that I could understand how it worked, it was actually very quiet, especially compared to some of the other small generators and it took whatever I threw at it for loads.

I've been aboard an American Tug 395 when the generator is running and there is no question that the Northern lights unit is quieter and does not have the "buzz" of the 3600 rpm unit. I did not find either objectionable...

We had put less than 200 hours on the FP before trading the boat in so I can't be of help answering questions about durability...

My understanding is the majority of generators die of both under use and insufficient loading. Every manufacturer will stress the importance of both.
I'm sure that bad installations play a part in premature generator death too.

We have to remove sound shields and look...
No excuse for getting caught with lots of damage due to inattentive sloppy maintenance.

5kW Northern lights, 1800rpm. About 5600hrs.

I would strongly suggest avoiding any 3600rpm gennie. Get a three cyl 1800.

1800 rpm Yanmar-based Maspower 8k here with 700 hours. It was vibrating like hell but recently fixed that with better mounts. So far no issues. Did replace the raw water pump recently.

PO had installed a 7.5kW Onan (1800) and a 2.5kW MASE (3600). The Onan was likely a 1980's unit and pretty tired. The MASE a late 1990's addition and poorly installed. I only started each of them once. Both ran fine under load (5 minutes) but were removed during refit.

I now have 2kW of solar, a Honda eu2000 and 200A alternators on each engine. The Honda has less than 10 hours use after 2 years. No aircon, otherwise a 5kW Northern Lights would have been installed.

5kW Northern Lights 1800 RPM with approximately 700 hours. Runs great. Just finished putting 7 hours on for the boat parade. I love the gennie. Easy to get at for service and all service points are pretty much on one side, reasonable noise (I don't have a sound shield), and runs everything I need.

I'm thinking about adding a sound shield but haven't done much research yet.

Only 1800's. Highest hours we have would be around 1200 hours. No issues with any of our generators.

4600 hours, Westerbeke 8kw. We are able to load the generator when used with two 100+ amp chargers, a 750 watt water heater and refrigeration.
