What did you work on/fix today?

[NorthernFocus]

After 10 years finally fixed engine coolant flow to water heater. It has always taken about two hours running at least 1500 rpm to get good hot water. We've worked around it by always showering on days that we travel. Finally installed a $20 booster pump and short circuited the fwd heater(which we don't use).

As with anything on the 25 Classic it was a real pita to get to things. Mounted the pump right beside the shower sump pump which is just fwd of the water heater. Used the circuit for the long since removed maserator pump for power. Now even at idle we get hot water in under an hour.

Finally got around to putting more fans in the main area. Lack of airflow on florida days is miserable when i dont want to run the AC. Figured i would put a pair of Sirocco fans in.
Shockingly, it was a 15 minute project.
I used the windshield wiper wiring (there is a switched, constant and ground right there) with a couple wago splices and they are good to go. They use almost no power and wont impact that circuit at all.

Lewmar ProFish 1000 repair.
In 2020 we replaced the windlass on our 2009 model R25. Had replaced the windlass motor(seized up) in 2016 and new that a complete overhaul would be needed this time so elected to replace the windlass completely. At time of the motor repair the windlass had a lot of water in it as is typically reported when people open them up. The new windlass installed in 2020 was a "gen 3" model with improved gasket on the split line. The windlass locked up while deploying the anchor on our first trip of this season. I was really disappointed that we only got five years of life out of it. Based on the symptoms and on my previous experience I assumed it was another motor failure. However when I opened it up the internals were in pristine condition with no moisture at all inside and no signs there had been any. And the motor was fine. So apparently the casing gasket in the gen 3 model is effective.

To make a long story short(ish) what failed this time was that the retaining nut on the compound gear(part no.51) came loose and backed off. The threads on nut and shaft were damaged. I was able to clean up the threads on the shaft but not on the nut. It's a specialized nut and is not sold separately by Lewmar. It comes as part of the compound gear assembly which is $140 item. I wasn't able to locate a replacement nut either on line or at local industrial fastener suppliers. So I ended up buying a standard hex nut for under a dollar and modified it on a bench grinder(pic below). Happy to say the modified nut worked and the windlass is back in service.

Good news is that the re-designed gasket on the gen 3 model of this windlass is effective. So Lewmar has corrected the biggest complaint/source of failure on this model windlass.

Thanks for this info. My motor seems to run when I hit the up and down buttons (I hear a whirring sound) but the gears are not turning. Do you think this retaining nut is a good place to start? The gears all look like they are in good shape. Any other ideas as to why the unit isn’t functioning?

Android GX Wifi Display
Victron has a new app that turns any Android device into a dedicated GX display. I took and old 9" android and installed the app which turns it into a dedicated GX display. Works great. Installed in front of the wiper motor assembly. Instant display of solar, DC-DC charger, Inverter and AC & DC loads, much better than the Garmin integration and easy to do. Highly recommend for those who have a CerboGX installedView attachment 25768View attachment 25769

Looks great! love a software solution!


im curious the value you get from the cerbo data. is it just to bring attention to the power usage at any given moment? seems like an expensive piece of kit for that purpose?

What do you mean by the "gears are not turning"? Do you mean the gypsy is not turning? Does it turn in either direction? And you said the gears are in good shape. Does that mean you cracked the casing and took a look?

Hi Dan, I did crack the casing. I hear a whirring sound of the motor, but generally the gears are not turning and neither is the gypsy. Other than a very greasy gear case, the gears appear not to be stripped. Very rarely, it goes into gear and the gears/Gypsy turns. I’m wondering if there is an issue with the 10mm dowels. I have read this on other posts. Any info would be appreciated.

There is a pin that drives the gear on the motor shaft. If that fell out or sheered it could do as you describe if there's no load on the gypsy. If I recall how the nut on the pinion comes into play the gears should still spin in the deploy direction but not in the retrieve direction. If you're referring to the dowels under the gypsy they wouldn't have any effect on whether the gears turn or not. Do you have the Pro or Pro-fish model? You have checked that the clutch is tight?

On our 2015 R31-cb the bow thruster all of a sudden started spinning with no effect. After watching the appropriate Youtube video and speaking with Imtra customer service, I easily replace the shear pin in less than an hour. The hardest part was removing and bedding and then replacing it at the conclusion. We had Imtra Side-Power SE 40/125S and the shear pin # is SM32050 (old #) or SM32050A (new #) - same part.
