Doesn't include boot or spade terminals shown
Does not come with the rubber boot or the spade terminals shown. Otherwise looks fine. Not installed yet so can't comment on performance.

Not compatible
Mercruiser owner beware- the specs on this do NOT match the ones posted in the owners manual for a mercruiser 4.3 engine with the thunderbolt iv or v systemBench tested at 1.5 ohms and the mercruiser specs are 0.6 - 0.9 ohms primarySeller did offer a full refund after multiple emails trying to get them to understand the product did not meet specifications for the 4.3 or even the 5.0 mercruiser

Fixed 4.3 Mercruiser starting issues
Installed on Mercruiser 4.3 with thunderbolt 4 ignition. Perfect Easy fit. Resolved an issue where my boat wouldn’t start when warm. Boat starts IMMEDIATELY now cold or warm. Couldn’t be happier. The fact that this was less than 20% of the OEM part was nice, and I ordered a spare just in case and still saved $60+ over the OEM.
