Does anybody have an engine manual for this boat and can tell me what the spark plug gap is please? Engine is a Sportrac S350

[TeamAllen]

I've never heard of that motor? Who is manufactured by?

The Mercruiser spec for my engine (5.7L EFI Gen+), as well, as all other Gen + engines, is NGK - BPR6EFS .045 in. (1.1 mm)

The specs for the other engines listed are NGK - BR6FS .040 in. (1.0 mm)

Dollars to doughnuts it's just a SB Chevy.
