Welcome to MOC!:)
According to the 1993 brochure , the Diablo O/B is rated for 140 HP , but I bet you could safely run a 150 HP unit at least.:yes_grin:
As for the manual............... really isn't a manual per se for the different models.
Take a look HERE for more info on this.

Once again , Welcome:wink_thumbup:

I was just reading about the outboard models a few days ago not very common it would be great to see some pictures of your new ride for the summer! Congratulations on your Mariah purchase welcome to the club!

I have the 93 Diablo 18 OB as well. Mine has a Mariner 90hp. Can you tell me your motor and top speed? Also, do you know your GPH fuel burn?

The OP made one post back in 2014 and hasn't been heard from again. Unlikely you will get an answer.....
