Our black scorpion starts instantly every time on the second time you turn the key. this occurs even when it is warm. is this normal? some type of vapor lock? i change the plugs and rotor also.
mine takes a lil longer than a car to fire up, after waiting for the gauges to turn on. i always tell people to let it turn over longer than they would in their car. works every time.
ditto, second turn of the key after I let the gauges cycle. I was about to go put a new filter on it since I just got the boat but it sounds like this is how they all are right?

i have replaced both fuel filters, cap, rotor, and all plugs and still the same. I just wanted to inquire before i take it in to the shop and spend the loot.
here is a scary thought...my friend just told me that his uncle's boat had the same issue and it ended up being a pin hole in the fuel line causing an air bubble.
My two mercruiser engines (not scorpion) take a little longer to fire than others. I do wait to prime the fuel line before cranking the starter and never worried much about it since it ALWAYS starts. Usually one turn of the key, but may take 2-3 seconds with the starter cranking. I have heard this was more common with Mercruisers and would be interested to know why if anyone knows.
Does the boat have an anti-syphon valve? The anti-syphon valve is a check valve that holds fuel in the line between the tank and fuel pump. Just a thought. If it is worn out and leaking back it could be the reason that fuel takes a moment to prime.
is there such a thing in the gas line? if there is, that very well could be it. Very strange thing though is that i checked and both pumps are working. i could not get it to duplicate the problem either. the only difference this time is i primed it twice before i started the 45 minute session of testing. maybe the outside temp was not hot enough to cause vapor lock. Good thing is there were no leaks.
