I have a 357 merc mag bravo L/V in my22' ,90 ultra with bravo outdrive, anyway when its cold like overnight sit, it'll fire right up with a tap of the ignition, after being on the water for a bit I like to shut it down float and chill for like an hour, go to start it up and it acts flooded, very hard to start but eventually get it started. thoughts? appreciate any feedback.
