Shared Meal and Engine Check

Kevin and Jenny are in the keeper's cottage, preparing a simple meal of boiled limpets and bread over the wood stove. The rain continues to fall, drumming on the roof and leaking slightly through the cottage shutter. Kevin moves to test the dinghy engine at half throttle while Jenny watches, notebook in hand, ready to sketch any irregularities in the engine’s vibration.

The humidity is heavy, the air thick and pressing against the keeper's cottage as the barometer continues its steady drop to 996 hPa, signaling an inevitable shift in the wet season weather. The tide is receding rapidly, exposing the slick rocks and salt-covered pools of the northern shelf.

Watch the RPMs closely. If it stutters, we have to pull the housing again.

Jenny opens her notebook to a fresh page and sharpens her pencil, her eyes fixed on the engine's puffing exhaust.

💭 peek at the thought

If that vibration doesn't stop, the sleeve isn't seated right, and we aren't making it to the mainland next week.

Half throttle now. Watching for the shake.

test the dinghy engine at half throttle

💭 peek at the thought

The shutter’s leak is worse than I thought—rain’s dripping onto the table near Jenny’s notebook. I’ll patch it after the engine test.

Slow it down a hair more. Listen to the housing.

Jenny leans forward, hovering her hand just near the metal casing to feel the vibration through the air.

💭 peek at the thought

The sound is too high. That's an uneven rhythm, not just fuel flow.

🔧 Kevin14:17

Housing's humming. Bracket's still skewed.

throttle back slightly and grip the engine housing to feel the vibration

💭 peek at the thought

She's right — the vibration's not in the shaft, it's the housing itself. The bracket's still off true.

It's the torque. We need to check the bolts again before the boat gets.

Jenny makes a quick, rough sketch of the bracket mounting in her notebook, noting where the metal looks worn.

💭 peek at the thought

If the bracket is skewed, the whole alignment is going to tear itself apart under the stress.

Through-bolts on the bracket. Epoxy's taking shear it shouldn't.

shut down the engine and grab the socket set to check the bracket's through-bolts

💭 peek at the thought

She means the supply boat. Due tomorrow. The transom bolts I tightened yesterday held, but the bracket's through-bolts are the real issue — they're pulling sideways on the epoxy bond.

🌿 Jenny14:19

Let me see the threads. If they've stripped, we're in trouble.

Jenny kneels in the damp grit, leaning in to get a closer look at the mounting bolts.

💭 peek at the thought

If the epoxy is holding the shear, the metal itself might be fatigued from the salt and stress.

🔧 Kevin14:21

One bolt's gone, one's stripped. Housing's not seating.

remove the Yanmar housing bolts and inspect the threads in the transom plate

💭 peek at the thought

Two bolts in the bilge were stripped or missing — we recovered one, but the housing's still not seating flat. The bracket's warping under load.
