    That would be extremely challenging.

    Fuel injection on a boat has been a significant challenge since boat makers started using it.

    Carb engines hold zero fuel line pressure when engine is off, EFI holds 40-60psi when off. That is challenge #1.

    My theory on this incident was simply a pinhole leak at a fitting or worn fuel line. Underway at speed fuel pressure would be at 60psi spraying a piss stream of raw fuel into the hull until hot exhaust caused a flame.

    Perhaps an automatic fire suppression system would have been the solution, especially if it was a halon system.

    I believe Supra offers an automatic fire suppression system.

    Hey Scott! where were you for this? we were in LP last weekend also. not near as eventful as you, but we did observe a Supreme pulling a wakeboarder strike a submerged rock (about rm 83) stopped the boat. launched a passenger over the bow in the water. they started taking on lots of water. we helped escort the boat to a shallow shelf to let it sink/stabilize in a recoverable condition. shuttled the passengers to their HB in Annies. The group had just arrived that day. nobody injured. the thrown guy was very rattled. our Supreme people at first thanked us off saying no need for help, but quickly called us back.

    Glad you could help the people. pretty exciting to see such a thing, safely.

    sucks for those involved and glad you were there to assist.

    looking at that tower and graphics, that boat is a good 10 years old easily. lots of things could have caused that. no one will ever know.....

    It may not be too difficult as OSHA requires detection in certain applications and the sensors are low voltage by design. It would be better to sense prior to the 25% of the LFL and operate the fan and send a warning message. In most cases opening the engine compartment, airing it out and keeping the engine cover open may be all that is needed to limp back. Pitching safety systems on sales works.

    Im always surprised at how quickly fires roar on boats. I've seen 3 boats burn on the water and all of them have burnt to the water level in 10-15 minutes tops....I told the family if there's ever a fire on board, grab a life jacket if possible and jump out.... Scary stuff, glad everyone's Ok.

    Fiberglass is interesting.

    The glass fibers are not flammable but will melt, but the resin is highly flammable.

    After seeing this fire, I am starting to consider the Supra optional automatic fire suppression system, itís only $570

    Ive always considered putting something like this in my engine compartment. I dont think it would completely put out a major fire, but it may buy the occupants some time.

    We were in 7 Mile Canyon up towards Good Hope Bay. Glad you guys were able to help out the Supreme, that can be scary running into something underwater. I absolutely love Powell, but i am always a little nervous out there on the water for fear of submerged rocks. Can be very sketchy out there.

    Speaking my language lol. Have to quote NFPA 497 on a daily basis with chemical safety design. We work with a lot of chemical and industrial equipment manufacturers doing installation and design oversight. We always alarm and increase ventilation at 10-15%, then start disabling ignition sources at 25%. At 75%, time to jump off the boat...

    Sucks the boat went up but glad everyone is ok.
