Tune Up Plug and Gap 5.7L Bravo

[rocklydockly]

I am doing an overdue tune up on my 1995 Rinker Captiva 232. Specifics below:

ENG: 0F287508 457B110HS 1995 MERCRUISER 5.7L BRAVO

DRV: 0F224039 5D30220HS 1995 MERCRUISER BRAVO 3 2.20:1

TRN: 0F513273 6020005HS 1995 MERCRUISER BRAVO TRANSOM


Thunderbolt V ignition.

I am replacing distributor cap, rotor, plug wires, plug, and I'm having the carburetor cleaned up and rebuilt.

Boat has been running decently, a little slow to start. WOT is 4200.

I bought AC Delco MR43T plugs, is the gap .035 or .04?​
