News From The Bilge

The last week I've finally started seriously doing some maintenance on Twister. The engine came out Monday giving me unhindered improved access to the propeller shaft stuffing box (seal that lubricates the propshaft as it spins but keeps most of the water out) and the automatic bilge pump (and the float switch that should turn on the pump when the water level in the bilge reaches a couple of inches). I replaced the stuffing (teflon-treated thread/rope) and discovered that last time I had only pulled out two of the four rings of stuffing. I re-did all the (potentially) underwater electrical connections to the bilge pump and float switch. Amazingly the pump and float switch had worked before even though the person who installed them had simply wrapped the soldered connections in black electrical tape. Then a check-valve or non-return valve was installed in the hose through which the pump pumps the water out. Previously the last couple of liters of water would always drain back down into the bilge after the float switch had turned off which would turn the pump back on resulting in a dead battery if left unattended (so far the new check-valve is working as planned). The engine throttle and gear-shift control had to be replaced which turned out to be relatively painless. Calibrating the barometer turned out to be ridiculously simple. Removing the air bubble in the compass was also pretty simple. The whisker pole is now almost good as new. As anyone who has spent time on Twister can attest, the toilet has not been problem-free. I had intended to replace the valves, seals, etc, but they were not be found in NZ. Also I spotted a crack in the pump housing. So Twister now has a shiny new toilet. I've left the engine work to the professionals . Sorry for all the jargon.
