Hey guys I've read through many conversations on hear trying to diagnose my issue and I haven't found my answer yet so here it goes.
I recently purchased an old boat with a 1990 evinrude 175vro outboard (vro pump removed) so I mix the gas 50_1. On my maiden voyage the boat ran great for 4hrs then after an hour or so of floating around I started it, it stumbled some so I gave it some gas in neutral to clean it out then put it in gear and it fell on its face and died now it will only pop and bang. I've got spark. I'm getting gas, even when adding gas or starting fluid it only pops. My compression is 90 give or take a pound on all 6 cylinders which seems kinda low but what really has me scratching my head is when checking timing it looks to me like its 180 off.
the light flashes at #1 TDC when cranking but when I remove the spark plug on #1 and turn the motor by hand until it reaches TDC the flywheel shows it's off roughly 180. I'm getting bolts tomorrow for my puller and I'll let you know if the key is sheared but any other ideas would be much appreciated.
