Midday Heat and Humidity

The overcast sky hangs heavy as the humidity rises. You meet at the cottage to discuss the engine results while the barometer continues to drop.

Kevin attempts to pull the Yanmar water pump housing and flange at the dock, but the bolts are seized by salt corrosion; he struggles with the pry bar and only shears one bolt head, leaving the housing partially stuck. Meanwhile, Jenny works in the kitchen, meticulously measuring the flange bore with the micrometer and dial indicator, confirming it is oval and requires a sleeve.

The leak in the tank is stopped for now, but I need to check the level again after the next rain.

Lean back against the stone wall, wincing as I shift my weight away from my left ankle.

💭 peek at the thought

The tank is holding, but my leg isn't. If the boat doesn't show in seven days, I'm going to be walking on fire.

Coupling faces show play at high RPM. Not the pump housing — the shaft itself, or the gearbox flange. Bronze adapter's machined to spec but the flange bore's worn oval. Need to pull the housing, check runout with the dial indicator.

set down the wrench, wipe hands on a rag, and walk to the cottage porch where Jenny sits

💭 peek at the thought

The vibration's in the coupling faces, not the pump. She's watching me watch the engine, not the ankle. Both of us mapping what might fail.

If the bore is oval, we can't just shim it. We'll have to sleeve it out.

Look up from the notebook, my pencil hovering over a sketch of a sea much's salt

💭 peek at the thought

If the shaft is shot, the boat won't run, and I'm stuck on this rock with a rotting leg and a failing garden.

Sleeve the flange bore. Bronze, same as the prop shaft. Press fit, then bore to size on the lathe. Have the bar stock. Have the lathe. Don't have a dial indicator that reads thousandths — only the one that reads tenths.

lean against the porch post, arms crossed, watching her face more than the notebook

💭 peek at the thought

She's already three steps ahead — sleeve, bore, shim — while I'm still stuck on the vibration. Her ankle's throbbing and she's machining solutions in her head.

🌿 Jenny07:11

I'll hand-file the fit. It has to be perfect or the vibration will just return.

Rub the side of my ankle, wincing at the heat radiating through the bandage.

💭 peek at the thought

Tenths aren't enough for a true fit, but I'll have to hand-file it anyway if that's the choice.

File's tip is dulled from the insulator. Won't hold a clean edge on bronze. Need the fine stones from the workshop, and time. The barometer's still falling.

reach into pocket, pull out the fine honing stone, hold it out to her without a word

💭 peek at the thought

Hand-filing a sleeve fit to thousandths with a dulled file and no indicator. She's not talking about the engine anymore — she's talking about her ankle, the infection, the helicopter that isn't coming. Perfect fit or it all comes apart.

🌿 Jenny07:13

I'll need the stones. I can't work the metal like that.

Take the stone, the grit cool against my palm, and look at the thickening clouds.

💭 peek at the thought

He's right, the file is a mess, and I'm a mess. My ankle is screaming.

🔧 Kevin07:13

Stones are in the workshop drawer under the bench. Micrometer's there too. Dial indicator's on the shelf above — tenths only, but steady. I'll pull the housing and flange. You measure.

turn toward the workshop path, pause, look back at her ankle

💭 peek at the thought

She took the stone. Didn't argue about the file, didn't say she'd manage. Just took it — and looked at the sky. The clouds are the same colour as the water was in Biscay.

🌿 Jenny07:15

I'll have the measurements ready as soon as the housing is off.

Close the notebook, stand up with a sharp intake of breath, and limp toward the kitchen.

💭 peek at the thought

If I can't get this fit right, we're just sitting here while the infection eats the bone.

🔧 Kevin07:15

Kevin — walk to the workshop, pull the micrometer and dial indicator from the shelf, set them on the bench beside the fine stones, then head to the dinghy at the dock

💭 peek at the thought

She's moving. Good. The notebook's closed. The measurements will be ready. The barometer's at 1001 and falling — maybe six hours before the front hits proper. The housing bolts are stripped in two holes, one missing in the bilge. I know every thread.
