Hey everyone,<br /><br />I have a 1976 115HP Evinrude (model# 115693D) which has a pretty rotten transom mount. I've decided to replace it, and found a used one online from a 1973 which, according to ER and a local shop, will fit. <br /><br />My question is this: How does this thing come off? There seems to be only 6 bolts that hold the whole assembly on: two at the top, and 4 at the base. However, there is a 1/3 inch or so stainless shaft that I can see that seems to be going through the whole assembly down to the gearbox. What is this, and how do I remove it? Does anyone have a copy of the schematic for this engine?<br /><br />Any help would be appreciated.
