The Low Tide Inspection

Kevin kneels by the dinghy, testing the impact driver against the seized Yanmar injector nozzle while Jenny sits on a salt-crate nearby, watching the tide as it recedes from the reinforced dock pilings. The heavy air smells of salt and wet wood.

No narrator was available, so nothing about this stretch was recorded.

Vinegar soak's done. Gonna hit it with the impact. Stand clear if it breaks loose sudden.

Position the impact driver socket square on the injector nozzle hex, apply steady pressure, and trigger a sharp impact burst to break the corrosion bond.

💭 peek at the thought

The impact driver's weight feels right in my hand. Good balance. She's watching the tide, not me — smart. Means she's learning the water's rhythm without needing to ask. The injector's been soaking in vinegar four hours now; corrosion should be broken down enough for the impact to break it free without stripping the head. If it doesn't, I'll need heat. Propane torch is low on fuel but there's enough for one good hit. Barometer's steady, wind offshore — good conditions for a sea trial after this.

Use the heat first. The metal is brittle from the salt.

adjust the ankle dressing unconsciously, feeling the throb pulse in time with the waves.

If he strips that bolt, we're stuck with a boat that won't start.

Heat first. You're right.

Pick up the propane torch, check fuel level, light it, and apply a focused flame to the injector body (not the nozzle) for 30–40 seconds to expand the metal and break the corrosion bond before attempting the impact driver.

💭 peek at the thought

She's right. Salt brittleness means the impact could snap the nozzle clean off at the threads — then I'm drilling and tapping again, three more hours I don't have. Heat expands the surrounding metal first, breaks the corrosion bond without shock loading the threads. Torch fuel's low but one focused hit on the injector body, not the nozzle, should do it. She's tracking the tide pulse in her ankle. Good sign she's conscious of the rhythm; means she's not letting the pain pull her under.

Watch the threads. Don't over-torque it.

lean back against the damp wood, watching the flame lick the iron.

💭 peek at the thought

The barometer is dropping again; the storm is coming before the boat does.

Short bursts. I'll feel when it breaks.

Apply the torch flame to the injector body in 10-second intervals, watching for the metal to glow dull red, then immediately test with the impact driver using short, controlled bursts — releasing pressure the instant the nozzle begins to tu

💭 peek at the thought

Threads are M8x1.25 — fine pitch, easy to strip if I get heavy-handed after heating. Torque spec for the injector seat is 25Nm. Impact driver can blast past that in a half-second if I'm not careful. Need to feel the resistance drop as it breaks free, then ease off. She's watching the flame, not flinching. That focus — she's measuring the heat by how the metal reacts, same as I would. Good. Means she's still in her body, not lost in the pain.

It's moving. Let it come out slow.

tighten the grip on the sketchbook, watching the tool turn.

💭 peek at the thought

If he shears the head off, I'm going to walk into the surf.

🔧 Kevin15:05

Easy does it. Almost out.

Continue applying short, controlled bursts with the impact driver while maintaining downward pressure, allowing the injector nozzle to unscrew slowly and smoothly from the cylinder head, releasing pressure immediately if binding occurs.

💭 peek at the thought

It's breaking free. Slow is right — sudden release could still damage the seat or leave shrapnel in the bore. Let the threads unwind under controlled resistance. She's gripping the sketchbook — not the ankle. Means she's shifted focus, using the task to stay present. Smart. The tide's still receding; we've got maybe twenty minutes before it turns. If I get this out clean, I can inspect the seat, decide if the spare injector goes in today or needs a hone first.

🌿 Jenny15:13

(a small, relieved laugh) You actually did it.

shift weight off the infected ankle and stretch the leg out.

💭 peek at the thought

Finally. Now we just have to hope the seat isn't pitted.
