Hi All, I posted a question about a leak some weeks ago and I finally got it fixed, thanks to all for tips and ideas. I got the elbow replaced and its been tested today, fun to be on water again. Some experiences I had: - Silicone spray makes hoses slip on fittings A LOT easier - Heating up eveything also helps - Grinding away soot is easy, just look for sparks when you hit metal - Duckt tape is great for holding bolts and tools together in small spaces - The engine area is very small and full of places to drop stuff. thanks for all help guys, now I need a professional to install an inverter, galvanic isolator and a lineswitch for the inverter. I'll leave that to professionals
