Re: What size? how many HP?

It's a 5.7 GM engine, but it's a Marine engine not a Truck engine. Blocks are the same, it's what's in them that makes them marine or truck.
You also have an Alpha I Gen II outdrive

(what the heck is a transom number??)

Gimbal housing assembly, inside and out. Includes trim pump.

Head up to the Adults Only sticky at the top of the forum. You can download the OEM service manual with all the specs in it.
You want manual #15 for the engine, 14 for the drive.
