Some have called Karl Keikerhaufer or however you spell it a crazy genius or just crazy. The small Mercs are a pain to work on unless you do it as a profession and they changed things like the cowling attachments so many times you will literally be looking at the small Mercs cussing into the wind asking how the hell do you open this thing. I have been working on a few lately and finding old ones for parts. They run good if they are running, but if not running, watch out! Many folks including me just do not like working on them period. They are over German engineered that tried to make them professional race like bullet proof , but they failed. OMC's are a delight to work on and will stand up to abuse much better. They are simply the King of outboards. They will do anything a Yamaha will (Yamaha are copies of OMC) with LIGHTER weight.
