Another 15 minutes

The boatingtrip on midsummer’s eve started out really well, the boat was behaving beautifully for a very long time until it was jinxed and the problem with something blocking the fuelpipe occured again. So the target remains, we’ll have to try to clean the tank yet again.

It was a good midsummer’s eve anyway, we had a nice picnic onboard at a nice location. On the way back we ran out of gas about 50 meters from the gasstation, but since it was closed anyway the irony was somewhat lost. Good thing I bought another 10 liter spare tank so we got 15 liters total to get home allright.

I took some pictures of the boat though, it’s an Örnvik 570 Cabin with a 155hk outboard motor which propels it up to around 40 knots (we haven’t actually measured the top speed yet), more pictures will be added later during the summer.

After yet another testdrive last weekend the same problem came back after a while, it worked perfectly for a long time though, so the problem was indeed inside the tank and something blocking the fuelpipe. But now I just needed to get the shit out from the tank somehow. So I bought a magnet and another pump, trying to fish and suck out whatever was inside once again.

First attempt was with the magnet… I don’t claim to be an expert or anything, but I’m pretty sure the fueltank is not supposed to contain rusty nuts and bolts =), so after removing those and then pumping out some more rust particles, I feel more confident that the problem might be solved. A testdrive this weekend will perhaps give the answer.

Today, after days of troubleshooting and replacing filters and lines, we finally located the cause of the problem we have with the boatmotor dying at high speeds. The symptoms pointed to the fact that the engine didn’t get enough fuel and actually was able to suck all fuel lines to a vaccuum. The problem is in the tank itself, something is blocking the pipe that is sucking up fuel from the tank. We know this now since everything works perfectly with another tank, but using the same fuel lines. So now we just have to figure out how to solve it, blowing some air into the pipe didn’t help. There is a flow in it, but just not enough I suppose. So while the troubleshooting is now ended, the problem solving part is now under investigation.
