Put a timing light on the engine.
The timing should be close to ten degrees.
If the timing was on the wrong side of TDC, I doubt the engine would run.
Most maintenance manuals have a picture of the damper and the timing marks.

i put a timing light on it and if im right about btdc it shows it is 18 dgr btdc and its suppose to be at 10-12 and the distributor was pointing at the number 4 jug so im going to go ahead and put a new built on it if i can get the tensioner back on and now the distributor is pointing towards the front of the motor is that going to throw it off time thanks?

This makes no sense to me.

hello everyone just a quick up date i put the new timing belt on last night and did a compression check this morning and it was 150lbs across all four holes .the reason i even started to mess with it because i had it out a couple of week ago and it started to run rough and it died on me on the way back in so i took it to a boat shop and they said it was the belt slipped because it was missing and i should replace the belt and check the compression after doing all this it is still missing like there is a bad plug does anyone have any idea what else i should check thanks and i hope this makes better sense of what the problem is
