Over the weekend, I picked up a 1998 Yamaha Four Stroke 25 hp outboard. It has power tilt and trim, and remote steering. I got it from a Honda dealer I know for $50. The motor starts right up, but it has what sounds like a rod knock. Otherwise, the motor is in decent shape, the tilt and trim works, it pumps water, ect. <br /><br />Is this thing worth saving? Or is it just better to part it out. I figure I could get at least $1000 for it if I break it up, but I'm tempted to fix it since it seems like the perfect motor to power a little Carolina Skiff. <br /><br />Are these generally good engines? What special tools are involved in getting the powerhead apart?
