You would be correct on being sealed.

Just sayin........

omg... hope they're ok. You hear of that every now and then. Was the key just turned to on position or started as well. Just goes to show even marine starters, alternators, distributors, etc can still fail. SS braided fuel and oil hose not properly routed can also be catastrophic. My current builds are going to be close to 90% premium nylon braided hose. "No arcing".

In addition to running blowers prior to starting my boats over the last 30 plus years I've always opened engine hatch/hatches for a quick inspection and leave open while starting. And still check for anything that could potentially raise a flag. Example, the first time I used a marina for a repair on a friends boat I had for a summer the mechanic slit the inlet raw water pump hose over a simple impeller replacement. Yes cost me another impeller in addition to a bad burn on my forearm I still have to this day. I slipped while trying to wrap hose with a towel temporary so I could get to land and got pinned up against the exhaust.

Boat was completely stock and the first time I never opened hatch due to being in a rush and look what happened. Nothing compared to an explosion or engulfed in flames.

Didn't mean to wander off OT subject but worthy of mentioning especially for non experienced boaters.

It was a twin engined beaker... As mentioned meticulously maintained blower motors and boat. THey were unable to determine exactly what was the root cause, but the fuel tank was highly suspect. Hatches were opened for several minutes, one motor was started and idling, turned key on second motor and flames everywhere, cockpit cabin and bilge, THey were able to get off and onto the dock with minor singes and crispyness. so both are ok but boat is totaled,

Very lucky. Almost sounds like a deal gone bad. Literally...

That sucks. Sorry to hear that.

I love that this is catching on. 4-5 years ago everyone thought I was crazy for thinking I could build reliable LS engine that were turbo charged. This summer I put over 45 hours on my 42 Fountain without a hiccup. The best part was all the double takes as people walked by it at the Shootout while we had it tied up at Ron's.

Keep up the good work!
