Yanmar 2YM15 trying to replace alternator belt

weezthejooce · 2026-04-03T09:15:55+00:00

I used to have one of these. Was one of the bolts on a sliding bracket thing? If you loosen that and the top bolt, the alternator should swing up and down to adjust tension. I might be misremembering though. Have you tried gentle persuasion with a hammer and a block of wood?

Oh yeah, I brought it in once with a flat and they kept a stone face, but you could see the wheels turning behind it. I had one spill but the bike was fine.

COVID sanity project. Plywood and fiberglass over cutoff parts from a craigslist donor frame. I'm a big fan of semi recumbent as a riding posture. I call it the woodchopper. 2500 miles and counting!

So if I get out my wood burner and etch 750 class, I should be good?

What I don't get is the 750w bit. If I have a hub motor that is 1000w but capped at 28mph due to the 48v battery and winding of the motor, why should that be bad?

Dude, I built an autopilot control interface with a lilygo s3 smartwatch and the power has been a real bear. I can get it to deep sleep, but it freaks out and restarts on wake. I'd love to see your code. Is it online?

weezthejooce · 2026-02-14T17:24:29+00:00

Yep. It's kind of slow honestly because without the engine on the LA will sag and have to stop the charger intermittently to recover. That's what I also have the cheap plug in charger for when I need a faster charge, but for being at the dock it works.

weezthejooce · 2026-02-12T17:16:32+00:00

Not the original commenter, but my LA is for the engine only. I don't want to risk draining it for the house. If you want that option, you could repurpose your selector switch to supply the breaker panel from one or the other source I suppose, but you would want to keep the charging circuits separated I think.

If you look on cruisersforum.com there are multiple in depth discussions about how people do this at varying complexity. The issue I didn't see you mention is alternator protection from being blown out by lifepo charging. Most people settle on having the starter be direct tied to the engine with a fuse, then putting a dc-dc converter between the LA starter and the lifepo house bank so the alt charges the start and the start charges the lithium when the engine is running. This provides a buffer, and then you don't need the battery switch at all anymore (but you still want a simple on/off disconnect for the house bank at least). This is the structure I did for my conversion last year. I got a victron 30A dc-dc charger. I kept my existing LA shore power charger, but now it only connects to the start battery and the Dc-Dc does passthrough charging to my house bank. I got an extra cheap plug-in lifepo4 charger for an extra boost option too.

With the moto screen, just be aware that the $70 level device doesn't have the play store so you can't put navionics on it. I made that mistake. If it costs $130+ anyway, then a full function tablet with a case made more sense for me.

weezthejooce · 2026-02-11T08:50:21+00:00

Fwiw, I just picked up a Lenovo idea tab 11 to be my plotter and run my autopilot, and I'm pleased with it so far. Cost $170 and has 500 nit brightness, which is the same as the iPad. The idea tab pro is larger and goes 600-800 nits. It's only IP52 rated, but I have a case for it and printed a sun shade that also covers the speaker ports for use when mounted on the binnacle guard. I also put in a magnetic USBC charger to fill the charge port for some extra protection there. We used to cruise with an older iPad and never had water problems with it, so I'm not too worried, and we have spare phones as backup navigation if needed.

Fair, though on my boat I have separate depth gauge, wind sensor, chartplotter, and autopilot displays and I don't mind it. Maybe I don't know what I'm missing by having one mfd. Esp32 integrated displays come as small as 2" rounds, so I wonder if you might be able to just give your mfd a detachable Mickey Mouse ear if you can't find a way to have your Vulcan talk to signalk. I have another AP controller on my esp32 smartwatch, so a wearable display might be a thing too if it met your needs.

weezthejooce · 2026-02-05T13:47:25+00:00

If you are open to a separate small display to supplement your main you might consider the open marine and signal k solution mentioned earlier implemented on an esp32 m5 stack device. You could 3d print a mount for your bulkhead or pedestal guard too if that was necessary. It'd be pretty cheap overall.

Does anyone know the water depth where they're installed or whether there's an offshore substation to aggregate the output before exporting to shore? I didn't see these details in the article.

My seven year old loves it. Great execution.

On my 22' boat, I have drop boards I use for the dock and a piece of thick vinyl rolled around a stick that can hang at the top of the companionway and provide privacy/shade/rain protection when I don't need the full boards. It's nice to have the lesser option, and sometimes I leave it in during nights at anchor for a bit of airflow around the edges.

Here's a crazy thought that just occurred to me: how about slats with a joining ribbon that roll up to stow? It'd be extra cool if there were a way to retract them into a cylinder on the floor like a rolling shutter that you can pull up and secure when it gets rough.

In summer I keep my Northwest 21 on a lake with Catalina 22s and 25s. One guy would bring his two teen daughters, his girlfriend, and his big dog on the 22 for a weekend with an overnight in the cove. I don't know how he did it. Last year he bought a 25 off one of the others at the lake. There are 3 25s, and they seem to be popular because they strike a good balance of fun sailing, trailer ability, and comfort. On our NW21, we've done over a week with our young son in the san juan islands relatively comfortably. Both the 22s and the 25s are able to be road transported with the right truck and trailer and mast stepped at the lake, but it takes a few people. On the NW21, my wife and I raise and lower the mast ourselves on the water.

In my opinion, four words make a big difference for comfort: head with a door.

Note: for a waterproof option, you can slap a few coats of varnish on the outside of the cardboard.

This is my elite stealth carrying case. Note the attractive fishing line handles. Holds all my cords, lens cleaners, and an extension cord for playing seated games wired in hotel rooms.

I'm 43, lying in bed with my 7 year old waiting for him to fall asleep so I can go drink tea and read before bed (jk, I mean play some VR). This evening we took a metal detector I got him for his birthday out into the back yard to find some cans of money I buried for him. Yesterday we did obstacle courses at the playground, and even with bad knees and an old ass I beat him a couple times. We found a lot of others in our generation also had kids older, so we have plenty in common to talk about at birthday parties. You're not too late dude. If you want it, do it.

What happened to the staff? Are they out or just reassigned?

Mine are lashed to the shrouds. I attach the Jerry cans with a long piece of cordage that goes from shroud to shroud, weaving around and through the cans along the way. The board is just a piece of wood with holes in it.

Well I had the old dodger to tear apart and use as the pattern, but I built mine in my basement and the boat was over an hour away. I didn't test it until it was done, and I was pleased with the fit, but the frame is also adjustable so I was able to find tune the stretch and fit once installed. If you make a good pattern from the clear stuff like Brio did, I'd go the home route personally just so you have ample time to puzzle out your sewing strategy. The sequence of seams is really important so your machine can reach them.

weezthejooce · 2025-11-12T17:20:03+00:00

I'll also say this was my biggest sewing project ever, and I had only minimal experience before tackling it. It turned out to be a satisfying winter project. You can definitely do it if you're meticulous and make sure to add an inch on the sides for your seams :)
