My dad has a 198617ft semi-v tracker. Currently has a 60hp 3 cyl 2 stroke mercury on it. The bottom cylinder has some cracks in the exhaust port. Don't think its worth rebuilding again (this power head is a reman from years ago) so I found a 97 evinrude spl 90 hp long shaft motor with controls for $1500. Question is, it should take a long shaft motor correct? And are these decent motors compared to the merc thats on there now? Thanks!!
