"I've been working on the upper gear housing on the lower unit of my Cobra outdrive (1989, 2.3L motor). Some have probably seen my other posts with questions... Anyways, I have two (probably dumb) questions. First, when I go to the shop.evinrude.com site and find my stern drive unit and select the 2.3L, there are four model # choices, and I don't find any of those on the outdrive or motor. They have BMR or BPR to start, and end with MED or MEF. How do I figure out which I have?
Second, Part #0911937 (Gear to U-joint nut) needs to come off so I can replace the stub & water pump shaft. How do I get that nut off? Is there a special tool, or just use a big adjustable wrench? I would hate to have to replace that too by wrecking it."
