I've got a 1983 merc 260 5.7l v8. Alpha 1 gen 1.
Had a hole rot through my intake manifold in july. I finally got every thing put back together and can't get it started. So I started from scratch and did a comp test.
#1 0 psi
#2 0 psi
#3 30 psi
#4 30 psi
#5 0 psi
#6 60 psi (after a few extra cranks since I saw it was at least holding and gaining psi)
#7 0 psi
#8 0 psi
Now ether I don't have a clue and forgot how to do a comp test or worse I totally screwed something up putting the new intake back on. I do have the manual for the motor from this site but would love some suggestions on what I've done wrong.
One other thing...
Upon putting the intake back on, with the distributer out the motor got turned over. I followed the procedure for getting that back to where it needed to be but in the process the motor was turned backwards to get TDC (just a little). Which now I read in the manual that little bit can destroy the water pump in the stern drive. I only bring this up because it would seem now that my stern impeller or water pump is not functioning on muffs. Is there a way to check the impeller with out taking the stern drive apart? I've also replaced the log type exhaust manifold and riser on the starboard side during all of this.
Thanks again all
