I want to install a generator stand (pad?) area in the cockpit lazarette of my Pearson 323. When the lazarette is opened you can see the side of the diesel engine so I know the Honda EU2000i will get more than enough air intake.

I have one concern. I do not want the generator to stay on the boat all the time. I want to be able to drop it in and hook up the exhaust. I can weld a nipple onto the exhaust muffler of the generator so I can hook up the flexible exhaust hose to the generator when it is put on the boat, but where should I run the exhaust to exit the boat?

Let me see if I get this, a portable Honda generator to be installed in a lazarette with a quick connector exhaust hose. I'm all for adaptive engineering except in applications with life and death implications. The Honda 2000 is gasoline fueled and gasoline fumes being heavier than air will tend to collect in the bilge at explosive concentrations. The exhaust is mostly composed of Carbon monoxide (CO) which is toxic for human beings. I will admit my total ignorance about exhaust hose for dry exhaust applications. I would be concerned about exhaust leaks and things like refueling. My suggestion build a box vented to the outside where you could store the generator inside the lazarette when not in use and take out when you need it. I wonder if you have already figured out how to pull the starter cord with the generator inside the lazarette. As far as transfer switch what are you thinking of using, a 20A plug?

I'd be rethinking that installation cause 1- gas engine = explosive fumes, 2- the heat generated by the exhaust (its not a wet exhaust like an inboard) when I have mine onboard (rare) it's tied to the mast and it can be run from right where it is or I can move it to the stern cause I have room on deck

Hundreds of our C34 skippers have these units, both 1000 & 2000 models. NONE of them have done what you're proposing. It's just a bad idea. Think "portable" not built in. Seriously.

Where do they store them when not in use? We bought one to have with us on the Endeavour, if we want to take it with us, and I'm trying to figure out where to store it when not in use.

In use it would be all the way up on the foredeck and we would never use it at night for say air conditioning.

Thanks,

Sum

Sum, the 1000 fits in the C34 port locker. The 2000s don't and skippers drain them by running them dry and most report they store them under their saloon table.

Hmmmmmmm This is why I ask. On our Oday we kept it under the tiller with a cover on it and when we ran it, we had it with the exhaust over the back of the boat like in the picture. The thought was that the front of the boat is always into the wind at anchor or when moving so the exhaust fumes are always leaving without ever having a chance to come into the cabin.



I plan on building a teak arched seat to sit behind the wheel running from one cockpit bench to the other. I guess the best thing will be to store it under there so it vents to the air, I had not considered the generator venting gas fumes into the bilge while sitting. I will just continue to run it on a cockpit bench with the exhaust going over the back.



Thanks for helping me think it through.

Don't be so sure. Alot of people have that thought, but there can be a reverse draft that actually brings the fumes in. People have died from it.

I would suggest a carbon monoxide detector in your cabin!

Did I miss something? You put the CO producing appliance on the bow while at anchor and the fumes DO NOT end up in the cabin? All the boats I know have the anchor forward and the wind blow from bow toward the vee birth hatch.
I'm thinking this is the second worst place to put a CO producing appliance while at anchor. the frist being in the cabin itself.

We have one. My wife insisted from day one.

Not sure who this is directed to. We keep ours on the stern.

Bill I would agree with that in most cases, but like a lot of things I feel that one solution might not be best for every case.

When we bought the Endeavour we moved it over a few days from Ft. Myers Beach to Port Charlotte and the batteries weren't good and we had to run the Honda 2000 in the morning and early evening for a bit to charge them. For that boat I feel more comfortable running the Honda on....



.. the bow vs. back in the cockpit.

The boat is...



37 feet long and the cabin if fairly high compared to where the Honda sits on the bow and it is quite a ways back to the cockpit. Also this boat has the very high...



....coaming that surrounds the cockpit. All of the above is going to cut down on any concentration of fumes that finally make there way back there and if it is windy the concentration is going to be even less and if it isn't I think the fumes will tend to find there way over the side near the bow and not up and over the cabin top and....



...the high coaming where I'm standing in the picture above.

We would never run the Honda during the night and hopefully we won't ever be running it again with the solar panels and new batteries. We don't run anything on the boat with 110, so hopefully the Honda has seen its use. If we did need to use it for some reason I'd still put it back where it was as I feel for 'our boat' it is the best solution. As has been mentioned above just putting it at the stern is no guarantee of safety.

On the Mac I wouldn't put it on the bow, the gen-set on it...

.... is on the stern rail with the exhaust down at water level. There again we would never run this at night.

Stu thanks for the reply on the storage question, it helps,

Maybe fabricate some sort of platform that hangs from the stern pulpit and an edge sits on the deck
