if anyone is still following this forum?  does anyone know the locations of the Hull Number ( i have been told the hull number is in two locations, not sure if that is correct) on a 2010 Challenger 210 sport boat?

Challenger 210 2010 model

First real start this summer.  Had some real issues with the starboard motor.  For the 1st hr it would fluctuate between running the same rpm as the port engine and about 1000 rpm less.  It was as if it had a partially clogged injector or periodic injection issue or maybe bad gas or clogged fuel filter. 

Then after stopping and restarting the engines several times and running them, the sync light started to come on sporadically.  Then once again after cycling the motors I obtained sync  and the rpm stuck together and in sync for 1 hr.

Rested the boat.  Could not get them to sync after that.  The rpm were close within 100-200 when comparing between the engines.

Any one have any suggestions?

Is it electronic? Or is there a physical linkage that does this.

have tried several steps.

any suggestions would be most appreciated.

has anyone had the following issue and if so how id you resolve it?

Intermittenly the radio will just stop producing sound.  if you ae playing ipod the song/musixc will continue to play, you can tell this adn the numbers continue ti increment.  But no sound comes our of any of the speakers.  balance fader etc all set correctly.  turn radio off, wait, turn radio on and sound will come back at the default settings. (i.e. if you had the volume set at 22 when it does come back on it comes backon at the default setting or 12)

Yes it sound like a short of some kind to the speakers.  i have searched low and High with no success.

if anyone has experienced this please share if and how you solved it.  or any ideas you all might have on how to solve this.

thanks

I have a Challenger 210 without a tower.  anyone have any recommendations on a ski mirror that would work well on this boat?
