The bow thruster was weaker during the season.
Eventually so weak that the bow barely moved when the propeller was activated.
I figured it was overgrown with broods and hoped to be able to clean it from the dinghy I found from the shed.
I carried it into the car, drove down to the harbor, carried it out onto the bridge where I pumped it up. When it was full of air, I threw it into the water, pulled it to the stern and climbed into it from the bathing platform.
Standing, I pulled it to the liner, where I found the tunnel to the bow thruster.
The tunnel was close to the waterline, but even though I stuck my arm all the way into the cold water, I did not get a proper grip on the propeller.
From the little I could feel, it did not seem to be particularly heavily overgrown. I pulled the dinghy back aft, climbed into the boat, went down into the fore cabin, removed all gear, duvets, pillows and mattresses so I could examine the engine.
There was 12,5V voltage on the motor. I started the motor by shorting the relay. The engine hummed fine, but I could hear the propeller barely turning.
Out in the dinghy again, pull me to the lining and feel more thoroughly after.
Now I thought I could feel the fuss of roughers.
Probably enough that the propeller was almost stuck when the engine tried to turn it. Concluded that I had to wait to clean the propeller until the boat came ashore.
Pulled the dinghy up onto the bridge, emptied it of air, packed it up and carried it back into the car
