Hi everyone!<br /><br />I got an extra motor for my 1973 135 Evinrude. It's mostly trash, but I stripped it down to the block, and the block itself is in good condition. My current running engine has really bad compression and will hardly idle at all (see previous posts from spring this year). So, I'm wanting to swap blocks myself.<br /><br />However, I'm wondering if a gasket kit like the following will have everything I need, or will I also need to order separate gaskets/seals besides the head gaskets:<br /><br /> http://www.boatmotors.com/mall/partfinder/gd_grid_id.171/gd_id.109043/gd_row.90/ <br /><br />Also, are these sierra gaskets good quality?
