I have a 2001 Mercury 225 EFI and the starter and the bendix gear will not engage (lift up) to meet the flywheel. I have lubed it, albiet with a one second shot of WD40 and made sure not to get any inside the starter while doing it. I move the gear up and down the shaft and it seems to freewheel easily. I checked the voltage on my battery with a meter and it is reading 13.3 V. I disconnected the terminals on each and and both are free of dirt and corrosion with nice contacts, but I cleaned them with a wire brush and contact cleaner anyway. Still will not lift up or engage at all and seems to be spinning fast enough. I made sure red was on positive and black on negative for my battery contacts as well. I also pulled the starter off and apart and cleaned the brushes a bit and the contacts inside with contact cleaner. Magnet looks ok too. Hmmmm. Kinda at a loss and I see that starters are upwards of 250-300 bucks. OUCH. Anyone think of something else, before I drop a dime on a new one?

Well, you got a good start but overlooked the worst offender. Take the battery ground cable off of the engine and give it the same treatment you did the battery connections.

Do you happen to know where that is located on the engine?

No, I don't. It is the big, black wire and it is bolted to the engine block. The reason it is the worst offender is that it is a tinned copper termiinal bolted with a steel bolt to an alloy engine block. Three junctions of dissimilar metals create hidden corrosion.
