Black scorpion hard starting

So I wondering if any body has to crank the ignition harder than lets say a car for instance, mine is almost to the point of being tricky. Mine is in a Sanger and my buddy has a nautique that he has to put the boat outta gear but a little throttle. My other buddy has to pump his throttle twice then crank ,so basically I am wondering is this coincidence or all boats have there lil tricks and quirks? Also by me having to crank my ignition the way I do is there something that could be causing this issue? Thanks
