Re: ONAN replacement or not?

And maybe without the genset the mast would be vertical! ; ) Which brings up the question of the weight of a full bank of lithium batteries? Mike ALETES SM#240 Rock Hall, MD

With new solar, and lithium batteries the future of gensets has almost come to an end. You can put 2KW of solar on deck with 900AH of LiFePO4 batteries (at 24V). This would life better than getting a new GenSet.
Keep the genset though, you might use it about 50 hours per year, max, with the set up above. And you might even get another 10 years of life out of that Onan. Onan's are very good gensets!

Danny if I remember correctly the motor and gear box are fitted to the vertical shaft that goes up to the winch with a keyway on the shaft and the gear box is bolted up to the deck/winch. I do not know if the bolts holding the gearbox up are threaded into a plate or if you need to remove the winch to access the nuts.

Alexander Ramseyer
Dear Amelians, my MDKAW is on ca 8000 hrs and I'm thinking about a replacement before sailing to the Pacific. The new 9 kW model (Marine QD space safer) MDKDL was offered to me for USD 12'195 - no discount. So here are my 2 questions: 1. Does anyone know a source that sells ONAN at a discounted price? If necessary please use private e-mail (alexramseyer@...)2. I understand that the diesel part of the generator should be good to be used up to 12000 hrs if maintained well. The electricity generating part however seems to be pretty much end of life at around 8000hrs. Does anyone have experience with renewing the electrical part? Does it makes sense to do that considering part and labor cost, assuming the revised gen-set will run at least another 4000h? Thanks for sharing your experience, Alex s/v NO STRESS currently in Carriacou

Thanks again Nick. You have answered my question about the gearbox being oil filled. Did you replace the seals. When you say you dropped the motor off were you able do remove the motor alone,or the motor and gearbox together leaving the winch in place. Or did you start drom the top and remove the winch first? Thanks again Danny SM 299 Ocean Pearl

engine exhaust high temp alarm Sea Chest Clog Alarm
toggle quoted messageShow quoted text
From: main@AmelYachtOwners.groups.io [mailto:main@AmelYachtOwners.groups.io] On Behalf Of Karen Smith via groups.io Sent: Sunday, November 29, 2020 9:18 AM To: main@AmelYachtOwners.groups.io Subject: Re: [AmelYachtOwners] Sea Chest Clog Alarm Thanks, all!
I was not looking to install one, just get a feel for the setpoint. A minimum setpoint of -200 mbar gauge (80 inches of water) tells me what I need to know. That's a significantly higher vacuum setpoint than I expected. I would have thought something like 20 instead of 200.
For our raw water system, (which is a lot simpler than a later model SM) the AC units quickly shut down on high pressure if there is insufficient water, the genset quickly shuts down on high exhaust temperature if it lacks water. Adding a high wet exhaust temperature alarm to the main drive engine will cover pretty much all the cases.
