Default Starter motor removal

Hi All I have a Maxum 180 with the 3 litre mercury engine , starter motor failed , can it be removed in place ? I think I can feel two bolts underneath can get a spanner on one but not enough room for leverage to slacken off

Some 3.0's also has a bracket at the front of the start to engine block that must be removed. Have you tried using a ratcheting closed wrench? The big tool manufactures make them including craftsman.

Should be a fairly easy starter to replace. Disconnect battery first. Couple wire connections two bolts and as Mike said a small bracket from end of starter to engine block. It really helps if you have someone young and flexible to do work. Good luck

Crows foot socket on a 1/2 breaker bar possibly. Remember the bolts are upside down so you turn from front to back of the boat to loosen.

The new starter will come with new bolts, verify they are the correct length as many have bolts that bottom out prior to the starter being tight to the engine and the bolts break off over time this way.

Most (Note I didn't say ALL) auto mechanics and DIY owners.

We could tell that was the case by the initial problem description.
