    How long is too long to run your generator?-gctid396526

    We have a Kohler generator in a hush box as originally equipped from when the boat was built. I have installed a dedicated squirrel cage blower for the generator that runs anytime it is on. To make things a bit safer for sleeping with it on, I have installed two hardwired CO detectors and two battery powered CO detectors. The logic board was replaced on the generator last year since it was corroded and failed and the generator would not stay running. It has run great ever since. I just had the oil changed one week ago.

    Okay.... all of that said, how long is it okay to run your generator at one time? My wife likes to run it for a long time, whereas I favor shutting it down to give it a break. Is 12 hours too long? What are your thoughts? Thanks!

    I've had 3 boat gensets now, and I usually only run them a few (2-3) hours at a time, to charge batts, make coffee, cool down the cabin, etc. Same thing with my RV gensets. But I have run extended times, 8-10 hours, to get a good night's sleep. I don't think 12 hours is too much, but like you, I like to give them a break. I like your dedicated blower idea, I think I'll do that on my 2858, got a link/pic? Sure can't hurt in our 110+ summers...

      As long as they get adequate cooling and lubrication, electrical and mechanical equipment, especially generators, enjoy the longest lives when run continuously. They don't need or benefit from a break, unless that break is for you to change oil.

      On longer runs, check the genny every couple of hours to ensure there's good raw water flow, good oil level, and not overheating in the enclosure.

      Tell your wife she was right again (she already knows but it's good for you to say it )

        I agree with Mike, they are designed to operate. Your CO level would be the concern.

        If the circuit board is doing it's job, any low oil or over-temp is supposed to shut them down.

        I too have a dedicated blower motor for the Generator.

          I agree with others. As long as its running well ie cooling, etc, it should be able to run 12 hrs a day with no problem. What I absolutely don't agree with is running it while you are sleeping. CO detectors or not!

              Mine requires an oil change every 100 hours, so I guess the longest it should run in 99.9 hours.

                I got the blower from our West Marine store. It isn't something that they usually carry, but the Jabsco one was on some sort of national backorder at the time. I had it mounted on the port side towards the back with the duct lined up with the genet. It is ultra quiet, which was my original purpose since the two factory blowers were about 12 inches from my head when I would lay in bed, and were wickedly loud. I had it wired so that it is switched from the cabin blower switch, and the original blowers are switched from the helm. I will grab a pic next time I have the hatches open.

                Regarding running it while we are sleeping... this is the only way to make the boat habitable for us at night while on the hook, which is how we prefer to spend most of our time. I have the automatic fire suppression system, and the two new wired and two new battery powered CO detectors. I am very safety conscious, and I feel that these measures are sufficient to allow for us to sleep with the genny running. I may be wrong, but I am confident that I am not.

                Thanks for all of the input!

                    Not sure the complete relevancy to boating, but we keep a plain 5500 watt gas generator at home for hurricane season, and I run it 24/7 when needed. After hurricane Wilma in 2005 (or 6?), I ran that generator for 25 days straight, shutting down only once for an oil change. To this day that genny still runs perfectly. So, I say, run the sucker and don't worry about it.

                      Will, good call on the squirrel cage blower motor. They are indeed much more quiet.

                      The motor that you bought is double ball bearing and is designed for continuous duty. I did the same for my two main blower motors.



                      The in-line turbo style blowers are on my list of red circle items!

                      They will move air, but are terribly noisy, and you can forget about continuous duty with them. :thumb

                        Many of my previous boats were gas and I too always worried about running a genny while we slept at anchor. The way we avoided it was to:
                        • Run the genny and A/C to cool the boat down at dusk. This also was part of our regular battery charging time.
                        • Make/buy good quality screen for every port and hatch, especially the companionway or saloon door.
                        • Use http://"http://www.breezebooster.com...reeze Boostersor similar in the forward hatches to promote wind flow through the boat and to give you rain protection so hatches can stay open.
                        • Use http://"http://www.breezebooster.com...rt Ventilators on a couple of opening ports. (Do 305s have opening ports?)
                        • Install good-quality 12VDC fans in the cabins. The current draw is so low that it barely factors into your overall charging plans.
                        • I suggest http://"http://www.caframo.com/marin...occo Model 807. They are almost silent, very efficient, and have electronic timers to turn them off after 2, 4, 6, or 8h if you want. We set them for 4h. By then you're dead asleep and the boat is cooler.
                        • Swim just before bed.

                          You know, tbqh I just replaced both of my blowers, costed me about 28 bucks per blower. I used RULE blowers, not attwood. For 30 bucks a piece I cant tell when they are running they are about 1/3rd as loud as my old attwoods and still move alot of air. Thats a decent savings vs the $100+ pricetag of the squirrel cage blowers a piece. I could replace 3 sets of these and still be ahead cost wise. Just an objective opinion

                          My attwoods lasted 13 years so far, and the only reason I lost 1 was the hose collapsed and a blower burned out. It would have been much longer for a real failure due to breakdown.
