You'll need to know if you're getting spark out the coil and to the spark plugs...Do you happen to see if the RPM gauge is moving any when you crank the engine over to start? Own a timing light to bring to the boat with you for testing?
May have hurt the sensor under the distributor cap and...
Wow, so awesome you found that hard to find fuse and better yet, it was the problem… what size amperage was this fuse? 15 or 20? Or?
Thanks for the follow up solution.👍
Sort of better to have an extra one on-board with the tools to change the sensor out should the need come to it out on the water.... Have a new rotor handy to as the rotor could get damaged during the R&R. https://www.mercruiserparts.com/bam/subassemblydetail/42256393/28171834...
Within reason, that would be correct though keeping in mind connecting to the PCM and confirming power and communication is present would be a crucial diagnostic step especially knowing there were possible codes beforehand...
Without a correct wiring diagram, all guessing would be still just as...
Hopefully the PCM isn't internally damaged, but if available to your engine application, do you know if you've located the clean power wiring harness which also has a fuse too like noted in the following description,

Can if you’d like to or if the connection seems loose fitting but often not needed as the fitting is a hose barb type fitting that holds it together relatively tight that or maybe if your boat runs 100+.🚤
Yes it’s for the speedometer tube.
Is one end connected to the stern drive still but not running up towards the bow?
The drive end should have a yellow plastic fitting that you have to give a quarter turn to R&R it….
If you haven't yet, the beginning test you'd want to do is try carefully turning the outdrive by hand while the engine is running to see if the play goes away while under power steering hydraulic pressure then/also watch all the steering components (from wheel to lever at the drive) inside the...
It's a 90-amp fuse part number 79023T90

Be careful with the flusher you linked as the price seems double ($74.72) of what they normally charge. OEM should be around MSRP: $46.49 with some $ saved if the website offers any percentages off such as Bam marine for example, https://www.mercruiserparts.com/44357q2-flushing-kit

That flame arrester appears dirty or oily too? Might want to remove it, clean it in say a solvent tank if possible, wash/dry it and clean the throttle body and TB plate too. Inspect/clean the pcv valve/breather hoses.
Either I missed it or don't remember but what are the updated fuel psi...
