Identifying current motor by engraved Block ID

Hello all. My first post ever, I’m getting desperate to get some answers. I recently purchased a 1989 Four Winns with what I thought to be a 3.0 but I’m unsure now after buying parts.

I went to do a tune up , plugs, wires, rotor, cap ect and when I got back to install everything the local Napa gave me it was all wrong. I then took off old parts and went in and bought what I needed. They said it was because the motor has been changed or at least the ignition system has been updated.

There’s some other issues but I really need to determine what motor is in the boat before I can continue. I’ve searched the inter webs long and hard past few days. I found some things really close but just not adding up. I believe it to be a GM long block 4 cylinder between years of 90-97 but I would like some extra confirmation on that. Is it a 2.3 or a 3.0 which is what is originally in the boat.
