Those aren't points . Looks like the sensor in a thunderbolt distributor. What are you working on ? merc serial number if u have it

 

[Clarko1988]

im not sure of the serial but its a 4.3 mercruiser. 1987

You have Thunderbolt electronic all that you replace is the cap and rotor

That's the old style sensor, and those solder joints look REALLY crusty. Are you having a problem? If so, what?

Have a read of THIS post to understand what you're looking at, and click HERE to see a parts breakdown (part #11 is the sensor).

That 'SAE J1171' is not a part number, or any identification at all. It's the standard to which the distributor conforms. It basically says it's approved for installation in a boat... Your distributor is a Mercury Marine Thunderbolt IV.

SAE is Society of Automotive Engineers. they write the standards

SAE J1171 - External Ignition Protection of Marine Devices is the standard that defines electrics in a bilge and fuel tank space that wont blow you up because there is no external spark potential.

Buy a new Mercruiser brand sensor. It's enclosed instead of open like the old one you have and is much more robust. Do not buy an off-brand sensor!
