Any idea if there is a connection that would affect cylinders 5 and 6?
Any idea if there is a connection that would affect cylinders 5 and 6?
Need to put a light on them and see when they fire.
5 and 6 aren't firing at all. I can hold the leads and crank the motor...absolutely nothing and I verifed the coils are OK.
My best guess is one of the pins in one of those big plugs is not making good contact.
I didn't put anything on the terminals when I plugged the connectors back together. Should I have put some electrical grease on them?
5 and 6 are two different circuits on the power pack and coils. Try disconnecting the shift interrupt switch and see if the fire comes back. I think you have something hooked up wrong.
IT'S ALIVE!!!!!!!!!!!!!!YAAAAYYYYYYYY!!!!!
I took all of the connectors apart at the powerpack and cleaned the connections with alcohol and then assembled everything with dielectric grease.
Finally, all plugs are firing and the engine roared to life for the first time in 3 years. I think I killed all the mosquitoes in the neighborhood, but after a while it quit smoking so heavily and sounds pretty good.
I had taken those connectors apart 2 or 3 times already, but apparently they just were not making good contact somewhere.
I have some more work to do before it's ready for the lake, but I'm really pumped that it's running.
Thank you Championman and others who have helped me through all the tough spots with your excellent advice!!!!!!!!!!!!
Huzzzzahh!
I took the boat out on the lake this afternoon and it went pretty well. Of course, I took it easy and varied the RPM frequently.
The only concern I have is the water pressure seems low to me, especially at idle.
At idle it is about 6 or 7 lbs. and increases to about 19 lbs. with increased RPMs.
What should the water pressure be at idle and moderate speed?
I don't have a jackplate and don't have the engine raised up high.
I'm thinking the water pump is dried-up.

If you didn't do it already, then change the whole pump assembly, not just the impeller. Did you also change the L/U oil? Three years is a long time to just sit - change it out to the new fluid.
Recheck your readings once you get the new pump in. I bet your numbers come up a bit.
I agree with Tom, I would change the water pump and housing. Your w/p is fine, just keep it above a very minimum of 15 lbs wot, and i really like 18 better.....

~5-7 PSI average.
