Machining and Prep

Kevin works the Yanmar lower unit on the workbench, checking the bronze sleeves. Jenny sorts the dried heirloom seeds on the nearby table while the trade wind whistles through the eaves.

Kevin completes the pressure test on the Yanmar lower unit, confirming the bronze sleeves hold at thirty psi without leaks. Jenny finishes boiling the limpets, the salty steam filling the cottage as they prepare for breakfast. A pod of dolphins breaks the surface off the point, mirroring the steady trade wind.

Sleeves are seated. Ready for pressure test when you are.

Wipe the bronze sleeves clean with a rag, set them aside on the bench, and pick up the hand pump to pressure-test the Yanmar lower unit seals.

💭 peek at the thought

The sleeves sit true in the housing — three thou clearance, exactly where they need to be. Pressure test comes next, then the mooring ring on the landward side before the boat arrives. Eight days out if the schedule holds.

I'll start the limpets first. I'm starving for something salty.

Picks up the handful of limpets and walks toward the wood stove.

💭 peek at the thought

He's so focused on the machine, he forgets the soil is literally changing under his feet.

Put a tin of corned beef in with them. Fat carries the salt better.

Connect the hand pump to the lower unit's pressure port, zero the gauge, and begin pumping slowly while watching the needle climb.

💭 peek at the thought

Good. Food first, then the test. The limpets'll take the edge off while the pump builds pressure.

🌿 Jenny22:02

I'll stick to the limpets for now. I need to save the beef for the boat.

Drops the limpets into a heavy pot of boiling water on the stove.

💭 peek at the thought

Everything is a calculation with him, even the salt.

Gauge holding at fifteen psi. No leak so far.

Keep pumping to thirty psi, the Yanmar's rated test pressure, and hold it there watching the gauge for any drop.

💭 peek at the thought

She's counting tins against the boat's arrival. Eight days if it shows. Twenty-eight if it doesn't. The gauge needle climbs steady — no drop yet.

🌿 Jenny22:04

Good. Keep it there.

Stirs the limpets with a spoon, watching the foam rise.

💭 peek at the thought

Fifteen, thirty... just numbers. He's in his own world of pressure and seals.

🔧 Kevin22:06

Holding at thirty. Seals are good.

Release the pressure valve, disconnect the pump, and wipe the lower unit dry. Then gather the wrenches and the new bronze bolt for the landward mooring ring.

💭 peek at the thought

Thirty psi held for a full minute. Needle hasn't quivered. The sleeves are sealing. One job down.

🌿 Jenny22:06

Don't forget the washers for that bolt. I don't want it vibrating loose again.

Drains the limpets into a colander and shakes them dry.

💭 peek at the thought

He's moving on to the dock already. He doesn't know how to just be still.

🔧 Kevin22:08

Nyloc and two washers. Threadlocker too if it's still liquid.

Grab the small parts tin from the shelf, check the threadlocker tube, then walk out to the dock with the wrenches and bronze bolt.

💭 peek at the thought

She's right — the last bolt walked itself out in a week. Nyloc nut and two washers this time, plus a dab of threadlocker if the tube hasn't dried up.
