The boat is a 1992 Baja Outlaw that I am putting a B&M 174 SC on. I need to know what motor is in it. My title says 380hp on it but you know how that goes. The only numbers that I can currently see are below. Any help would be wonderful!!!!

intake is 2629318 or 6269318 eyes suck

Block cast is 1005H07 or 10051107 eyes again


I need to know what the HP rating is and if it has forged pistons and crank so I dont have to build one.

Thanks, Brian M.

Brian,
The block is a MK4 Bow Tie 454 block. That is all you can tell from the casting number. You cannot tell what camshaft etc was used from that.
If it is a Mercruiser engine, there should be a Mercruiser plate riveted to the block that will have a serial number on it. With that number you should be able to find out the original configuration of the engine. If it has been remanufactured or otherwise modified, it may be impossible to find out what the internals are without disassembling it.

Hope this helps,

where do I look on it for the plate? It was late tonight when I decided to uncover it.

Thanks for the info so far. I will go look tomorrow morning and post what i find.

It is riveted to the back of the engine behind the starter area.
