I remain to be convinced by that explanation....I've never seen a PWC engine do that before, and I've seen many many starts over many years (but not on this particular model engine). During the start cycle of this engine do the igniters energize as soon as the starter is engaged? I suspect so, so if that was fuel being blown out the engine I'd expect it to be like a flame thrower and not smoke like. To me that looks like oil smoke, from oil that has leaked past a seal that shouldn't. And leaking seals can turn into bad bearings. And bad bearings can turn into failed engines.
