I just acquired a Carrera 205 that has its share of stereo problems...
It came with a bitchen Alpine head unit, 4 Blaupunkt speakers and an amp (haven't seen what kind yet)
When the blower, bilge pump or ign. is on I get tons of interference... can't hear a damn thing but screeching... I was told that I need to run shielded wire on the amp to get rid of this problem... I'm also gonna install a MSD ign. filter I have laying around to make sure...
Is this really the case, and what wire is best? Any other suggestions while I have the interior gutted?
Thanks.

I'd try upgrading (and isolating) to a big-ass ground and power wire. It's been my experience that noise coming from the dash is usually because someone was lazy and used the stock power and ground wires.

you may want to run dedicated power and grounds to the stereo equipment to reduce any problems from coming from the existing boat wiring.
