For you who don't understand that term, it means, "I made a big mistake". You lot must be really starting to wonder about me.
I forgot the really simple basic task of ensuring the engine
seawater intake was on. I normaly leave it on all the time. It is in a stupid place to get to and turning it off after each time I come in is too hard. Seeing as we either go out often in summer, or run the engine
regularly in the winter, it is easier for me to leave the valve on. However....over the weekend, I decided to replace the impellor, seeing as I had not done so for four years. It came out easily and was actually in good condition. A new one went in anyway. However, the packet the new impellor was in had been opened and the gasket
was missing. Dang it I thought. Oh well I will try and reuse the old one. So after I finished the job, I turned on the valve to check for leaks
and sure enough it leaked. So I turned the valve off again and removed the impellor cover plate and spread some sealant
around it. I screwed this up tight again and then thought, I will open the valve later once the sealant
had dried. Well guess what? I forgot didn't I.
So we (3 of my students and one of my fellow tutors) are heading out of the marina and all is well. The engine is still warming up and hadn't reached full temp. I was at a rather critical navigational area when I suddenly heard a change in the exhaust
note. The other Tutor said he couldn't hear anything different, but I knew something was up. I senses were hightend and I noticed the sound of water
wooshing out the back was not there. And then it suddenly hit me. OH NO!!!! the water
is off. I opened the Engine room to be meet with clouds of smoke and fumes. I took a deep breath and climbed in and found the valve and turned it on, lept out and slammed the hatches down to keep the smoke in. I knew the exhuast system was compromised, but the engine should now be getting at least some water to keep her cool, providing the impellor hadn't totaly disintergrated. I swung the boat around int he channel hoping I didn't run aground and headed back to the marina hoping the engine wouldn't quite. We entered the marina and I noticed the engine starting to slow down. Oh no, please don't that be her locking up. But the engine temp guage was good. I wasn't sure what was actually making her slow in revs. Was the sender no longer in water and telling me lies or was there something else. I cam to the conclusion that the fumes below must be so thick it was causing the engine to suffocate. I was counting down the metres to go, just a little more, please oh please. I got to my birth and started to swing her. Right at the critical moment I selected reverse and opened the throttle, no response at all, she just stayed idling. Crunch into the end of my pier. Oh no not my new paint
. We side swiped the pole which swung me into the birth and I came to a not to hard a stop against the end of the birth. I instantly shut her down and told everyone to get off, we may have a potential fire below. I grabbed the extinguisher and open up the engine room. Great bellows of smoke and fumes erupted out, but no flames. I turned on the extractor fan in the engine room and we sat down for awhile waiting all to clear.
It seems that all that has been damaged is the Exhaust
water lock. Rather melted. Man I wish they weren't plastic, but then there ain't no perfect material to make them from reality. I Don't know about the impellor yet, but I bought a new one just incase. I have ordered an new water lock, which is setting me back NZ$350.00 Ouch, it's just a Vetus LP60 water lock. Why do these plastic things have to be so expensive.
The rub strip was all that swiped the pole and dock
, so my paint
is all OK. I think the fact that the engine lost
all power was the smoke and fumes and probably teh filter blocking with this thick crud. My throat is quite sore tonight and I even went hoarse for awhile earlier. Some would say that was a good thing.
I think at some stage, I need to get a water flow alarm
. But once again, so expensive.
So, that was my day, how was yours?:-)
