Boat equipment goes wrong all the time, maintainance is a big part of sailing and living aboard. Think of a boat being your home, which includes electricity, plumbing, gas etc. It is also your transport so engines, sails and rigging need to be maintained. It is your security, so general seaworthiness, anchor, flares, radio comms, distress beacons, life jackets, liferaft and many more things besides. As Martina mentioned in a previous blog post several things went wrong just before I went back to England. The outboard motor on our dinghy stopped working, the main diesel engine overheating alarm went off and the foot pump started leaking badly, filling our bilges with water. These things and more needed sorting out before I returned to the UK so that Martina could have a dull uneventful week of peace without me.
First of all I attended to the leak in our fresh drinking water system. I took the foot pump out, water momentarily gushing all around me, and I shoved a couple of wooden bungs in the ends of the pipes, tightening hose clips onto them to stop the leak. This left Martina with only the electric pump, which we don’t like to use when on anchor, with only our 80 W solar panel to keep the systems going, but that was fine because Martina had no intention of being at anchor without me on board. We spotted an opportunity to go alongside the pontoon at Sanlucar a few days earlier than we needed and early in the morning we brought Carina into Spain, just in time to make the 5 minute walk to take the girls to school. Life was beginning to look easier for Martina stuck without me. On the pontoon she could do the shopping, take the girls to school and had limitless water and electricity with Carina plugged into the mains. This meant being able to use the computer and DVD player without limit, DVDs for the girls, a blender for smoothies and even a fast electric kettle, a working fridge and hot running water, pretty good hey!
The next job was the dinghy. I couldn’t leave Martina without the ability to get across the river, go to the Saturday market in Portugal, use the 3 Euro a go washing machine, which includes the powder, and go to the library where she can plug in the computer and use the internet all day long for her writing work. She might even decide to exchange books and look at the art gallery. I suspected the problem with the outboard to be dirt in the carburettor. We have a small, very simple and usually reliable outboard which I think is vital for an idiot like me, miles away from a petrol station or a professional mechanic. So I stripped down the carburettor, couldn’t see the problem but did a few of my magic blows on it and put it back together again, it worked a treat. The next mission was to teach Martina how to use it. “WHAT!” I hear you say, how could she live on the boat and not be able to use the outboard. Well it is a long story, she did use it a couple of times under supervision when we were cruising down here but we spent last winter in a marina and she hadn’t used it since. So I watched as she went off with the laundry, shouting things like “A little more choke!”, “No you’ve flooded it, try rowing straight back at the shore.” Anyway finally she seemed pretty happy and could handle the oars, so she had her complete freedom while the kids went to school.
I ordered spare rubber parts for our very good Whale Gusher Galley Mk III foot pump which hadn’t let us down or needed any maintenance in four years of very heavy use. We don’t know how long it was before we bought Carina since any work had been done on it. These parts would arrive at my dad’s house for me to bring back from the UK and I flew out from Seville to London for my appointment with the consultant. On my return I was first annoyed because Martina filled up the water system, but I waited a couple of days then emptied it and took the pump apart. Sure enough I found a small hole in one of the diaphragms. I replaced them both, saving the good one as an emergency replacement. Now I just had the engine to sort out.
The main engine of Carina was a little more confusing. The temperature alarm had gone off when on full pelt on our return from Ayamonte but now it was giving a faint alarm and a faint warning light after running the engine for 20 minutes or so. The system is cooled by a flow of raw water (sea or river) around an inner engine coolant water. Previously we had trouble with the flow of the raw water due to a seal not being good on the inlet filter but it was clear this was not the case, the filter itself was also clear. I remember going to sea with my cousin Martin and him replacing a degraded impellar (the rubber thing that pumps the raw water around the engine), that day the two of us sailed onto the mooring in the confined space between lines of boats and mud banks of Hayling island, near Chichester and we missed the tide that would get us to the pub. With this in mind I checked the impellar, it looked fine.
Various people came past and nodding sagely said “It will be the thermostat!” I ignored them and checked the raw water system some more, actually contacting the dealer to see what the flow should be, I then put a bucket by the exhaust and measured how much water came out in 20 second intervals, it appeared to be behaving fine. Finally I heeded the advice of my fellow sailors and took out the thermostat and put it in a pan of boiling water. It opened just fine, not that either then! I was getting pretty sure that it was just a faulty temperature sensor, but I didn’t have the confidence to risk the engine. However, the Germans had heard that I was looking for a thermometer and came on board with their engineering kit and took over for an hour or so. Rolf was an engineer and still does the odd professional job on boats at the coast. Along with Steffan, a keen amateur, they gave the engine a good testing. The verdict was that it isn’t overheating, I have a dodgy temperature sensor. I checked the price of a new one with the dealer, £49.95! Maybe I’ll take it out and blow on it before spending the money.
