I inflated old dink and I'm patched the floor so that I can use here while I try to find the leaks in new dink. New dink fooled me by holding air for only one day…
Also yesterday the solenoid for the engine shutoff did not work. I have to debug that electrical problem. Chances are it is caused by the lousy wiring harnesses used on Yanmar engines. I took the panel apart this morning and this afternoon once it cools down a bit outside I'll start testing for continuity and voltage.
