Hi, some updates on my quest to fix this old outboard. I have machined the fuel inlet fitting myself (I will attach some photos of it later). It's a M7x1mm. It's not pretty, nor perfect, but I think it will do the job just fine. I now need the flywheel nut, since the thread of the original one is ruined. I bought a M14x1.5mm nut, but it doesn't fit. I presume it's a M14 fine pitch, so M14x 1.25mm. Can somebody confirm if this is the right thread for the nut or if it's an imperial one? I have tried to reach out to "Snickeri & Marin i Näsum" for spare parts on their FB page, but I had no reply.🤔

I have disassembled and cleaned the carburetor and I have realized that the fuel inlet fitting is missing from the fuel clear bowl assembly (see images attached for reference). I presume there was a fitting similar to the banjo connection on the upper part of the bowl. The bottom hole has the same thread as the upper hole, I have checked this by connecting the banjo bolt to the bottom hole and it fits. I measured the banjo bolt thread and it's a bit more than 7mm in diameter. Can somebody confirm which thread size is the missing fitting for the fuel inlet? Thanks in advance. Jack

Thanks Pär. Much appreciated. That's a beautiful schematic photo of my engine. May I ask where you got it from?

Thanks Pär. I will try all that and provide some updates.🤞 P.S. I don't understand or see from where the outboard sucks water in for cooling the engine.

Hi Pär, thanks for your prompt reply and support! I have cleaned all connectors and breaker points and I have managed to get sparks on all spark plugs!!😃 Now, onto the next problem which is: where do I connect the fuel line from the fuel tank to the engine? I presume it needs to be connected to this point?? After I do this maybe I can attempt starting the engine to check how it runs.😃 Thanks in advance. Jack Jack

Hello everyone, I'm new to this forum and also to boating and outboards, so I hope being here will help me to get up to speed with the basics. I just bought a second hand Crescent 45 outboard 3 cylinders. Through some internet research I have done, I believe these engines are also known as Archimende Volvo Penta. It's got good good compression on all 3 cylinders. I have checked this with a compression tester. However, it doesn't seem to have any sparks on the spark plugs. I have tried to change the one of the plug, moving it between the coil leads, but still nothing. I have then tested the 3 spark plugs with a spark plug tester and they all have spark. I have checked the ignition coil primary and secondary windings and they seem to be fine, primary reads 2.6 ohms and secondary 8.7 K ohms on all 3 coils. I have also checked the wires that go from each ignition coil to the connections pack, and they are fine, as they have good continuity (0.1 ohms of resistance). I presume there is something wrong with the stator / trigger or with the points ignition. See photos of the engine attached. Can someone help me to understand what do I need to do to understand if there is an issue with the stator / trigger? Does anybody have a service manual that could help me to troubleshoot the issues? Many thanks in advance. Jack
