Rattle when First Started

[jcurrier]

I have a 2014 242 Limited and when I first start the boat after putting it in the water I hear a weird rattle from what appears to be the starboard side. After about a minute of running or if I give it a good amount of gas it all goes away and wont reappear until I take the boat out of the water and relaunch again. its only when it first starts in the water.

Any clues? It sounds very similar to when you start a jetboat out of water. Doesn't sound bad or even like something is broken but just odd.

Did you ever figure this out? Mine does the same except it sounds more like a weezing. Best I can describe it is the starboard engine sounds like its a child who has asthma and weezes a bit. But once I warm it up and run it a bit, it goes completely away.
