Apart — Kevin at the dock, Jenny at the tide pools

Midday Heat and Salt

Kevin is at the dock with the engine components, while Jenny waits for the tide to turn.

Kevin runs the Yanmar engine under load in the dinghy to test the recent cylinder head assembly. The engine performs smoothly without vibration or leaks, while Jenny explores the receding tide pools for limpets for the evening meal.

🔧 Kevin — alone at the dock

You inspect the gasket surface for signs of scoring after the load test.

🔧 Kevin23:30

Kevin — shut down the Yanmar, let it cool ten minutes, then crack the cylinder head bolts in sequence and lift the head to inspect the gasket surface on cylinder three.

💭 peek at the thought

Engine ran clean at load. No smoke, no knock. That vibration above half-throttle though — still there. Prop shaft or the mast bracket alignment. Need to pull the head and check the gasket face for witness marks before I call it done.

🔧 Kevin23:34

Kevin — re-torque the cylinder head bolts to 35Nm in sequence, wipe down the block, and start the engine again to confirm no leaks at the head gasket before pulling the dinghy up to check the prop shaft runout and bracket alignment.

💭 peek at the thought

Gasket face is clean. No scoring, no gas tracks, no witness marks from the repair. Cylinder three sealed proper. The vibration's not in the top end. That leaves the prop shaft true or the mast bracket alignment — and the bracket's the one I couldn't get dead straight even with the through-bolts.

🌿 Jenny — alone at the tide pools

You watch the water line, waiting for it to begin its retreat.

🌿 Jenny23:29

Jenny — squat down by the furthest reachable edge and use a small pocket knife to pry a stubborn limet from the rock.

💭 peek at the thought

The tide is coming too fast; if I don't move now, I'll be stranded on this shelf in minutes.

🌿 Jenny23:32

Jenny — wipe the salt off the limpets into the bucket and stand up, popping my knees.

💭 peek at the thought

My fingers are freezing from the salt water and my stomach is starting to growl louder than the waves.
