I have a 2004 Wellcraft 210 Sport with a Mercrusier 5.7L engine. I removed and replaced the battery because it would not hold a charge. When my son hooked the battery back up he reversed the terminals for a split second. There was sparking and now there is no power to the gauges or the starter. I checked the 50 amp circuit breaker but, it was not tripped and I checked the ignition fuse and it was not blown.

What else may have occured? Is there another fuse I am not aware of? Could the starter solenoid been blown?

There is power to the trim however no power to anything else.

Thank you in advance for your help!!!

At the starter,try jumping the yel/red wire to the main batt lug. starter should spin the motor. If it does power is good to there, if it dosent ,check the battery cable connections.

See if there is a big fuse on the side of the starter, should be a white plastic block looking thing. Some boats have those, and the power to the dash, etc feeds from it. SImple check with a test light if its there, both sides of the block should light a test lamp. If its blown, only one side will light.
