We recently bought a 2001 406. We also have an 88’ 3807 we are prepping to sell in the spring. Both have fire suppression bottles in the engine rooms. New insurance company list having the bottle on the 406 certified as a post survey “must do”. I carried it to two local companies that said they couldn’t do it because the bottle was older than 12 years and didn’t have any previous yearly certification tags. ABYC standards say you have to have at least 2 BC, 5lb non serviceable extinguishers IF you have an automatic bottle in the mechanical spaces. 4 if you don’t have a bottle in that space. Could I just have the bottle ( reads pressure on gauge and weight matches what’s stamped) and not count it and have 4 portable extinguishers? I know I have to satisfy insurance, but I hate to buy a 1700.00 bottle just to get a stamp, when I have no doubt my existing one is functional. I’ve asked all my dock neighbors if they get yearly inspections and nobody wants to talk about it. Just wondering if I have reasonable options. Thanks in advance.
