coincidence or did i cause this,

[wellcraftv20step]

Hey all , A while back I picked up a beautiful 22 Imp walk around with a 5.0 mercruiser Alpha 1 for my son in law, I started it for the first time last week and it started and ran great then I started it a couple days later and it ran perfect again. Here's the rub . I decided to do a compression test and all cyl,s registered about 150 ,so now I put the plugs back in and I cant start the engine. No spark at the thunderbolt iv v8 22 ignition module. my question is could this have been caused by the constant cranking of the compression test or is it just coincidence, and I did change rotor, cap, plugs and coil

First, check the kill switch on the shifter, make sure you didn't flip it off or pull on the cord, reset it and know you're good. Then jiggle the shifter and retry, you may have activated the shift switch that shorts out the ignition so the drive will come out of gear.If that didn't fix it, pull the cap off and make sure nothing broke, its easy to not push the rotor all the way down and the first time you spin it over, it breaks something. After that, try this http://www.boatfix.com/merc/Bullet/83/83_24.pdf

Thanks so much Spare, I changed out the Rotor cap and coil after it would not start just because I would have done that as regular maintenance anyway, and I actually found and followed that series of test you suggested and that's how I came to conclusion that I need the ignition module. However I will try that shift control idea !!!!

Spare, i got a used thunderbolt ignition module and still no spark,finally i found the problem it was a short in the wiring harness coming out of the module. Running great now. now onto the outdrive. thanks as allways

I see that when I start her warm I need to put the throttle full forward or wide open, she sputters for a second then clears rite up. any suggestions.

back off the choke a little

sooooo, last night I put the drive on the boat with no issues . I then start the engine and I notice as I am going from neutral into forward and reverse their is no change in sound , I put the shifter in neutral and take a look at the drive to find that it is in gear. Forward I believe from memory ! Shift cable..... Outdrive..... Or throttle . now I"ll be at work all day stewing over this one. What should I be looking for ,thanks

when you puut the drive back on did you have the drive in forward gear and the shift lever pushed fully forward? That's presuming you removed the drive from the bell housing

[wellcraftv20step]

Thanks Liam, yes I had the drive in forward. I watched a youtube video at 4 this morn on shift cable adjustment, went out and followed his directions and it was way out of adjustment now it seems to begoing into reverse forward and neutral now by just spinning the prop. Its much to early yet to start her up . This is pretty much normal stuff when you buy a used boat. I am assuming I will still have some issue because why would the shift cable be so far out of adjustment to begin with

[wellcraftv20step]

I stated her up today and the prop was disengaged as I had hopped. Put the throttle forward and sure enough she went in gear ,but I still heard no momentary cut out from the shift interrupt switch and when I put it in reverse she stalls, back to the drawing board
