The smoke filled the cabin. I quickly reached for the fire extinguisher mounted nearby and put the engine room fire out. If the extinguisher had not been mounted in a pre-planed fixed spot and allowed to drift about in the cabin I would have had a major disaster on my hands. Mount the fire extinguishers in key spots, make sure they are updated and in good shape. Do not pump cold engine oil .
Smoke fills up a cabin in a few seconds .
My boat is an older boat that various unknown people have worked on over the years. Someone wired the oil pump without putting an in-line fuse . You may be like me, you may find out little hidden disasters waiting to happen. Hopefully you will be on the look out for wiring not fused . You never really know until the fire starts.
