I have a 1998 crownline 202br. Has a 350ci alpha outdrive. My issue is key on boat running or not when the radio is on and you hit any other switch; blower, trim, dash or nav lites the radio shuts off for a second then turns back on. Or if blower is running and any other switch is turned on the blower slows down. Are my batteries bad is it a bad ground. Help please!

Are my batteries bad is it a bad ground.

Maybe, have you load tested the batteries? Clean tight connections, not missing any +/- leads at the battery? Is the alternator maintaining charge properly?

Sounds like one or more bad electrical connections

All connections are clean and tight on the batteries

Under the dash everything is clean. I had the problem last season. I’m in the dewintering phase. The testing today was with motor off
