These multi electrode sparkplugs not only economized my Scorpion but gave a real pep to the boat. I was pleased with the shippnig and the packaging on the top of that I was delivered top of the line support. I do recommend this company to others. One negligible flaw the price should be elaborated.

Brisk sparkplugs far outperformed factory plugs and I even managed to have the boat average better. more

Originally developed by Mercury and the Orbital Engine Corp., OptiMax uses a belt-driven compressor to deliver pressurized air and fuel to each direct-injector nozzle at the top of each cylinder. The injector shoots a "plume" of air and fuel droplets about 10 microns in diameter - about 89 times smaller than a human hair - into each cylinder. Each plug ignites the air/fuel mixture with power from its own high-energy ignition coil, which is controlled by the electronic control module. The ECM can determine and control spark timing and duration for increased performance and complete combustion. here
"There are other 115-horse, direct-injected engines on the market. But there is no V-6," says Tony Esposito, spokesman for Mercury Marine. "We think we can position this engine based on its performance." [links]
Mercury offers the first V-6 direct-injected engine: the 115 OptiMax.
Like all other OptiMax engines, the new 115 severs ties with past two-stroke lubrication systems. Rather than the conventional approach to internal lubrication - mixing gas and oil to smear every engine component with a lubricating film - Mercury engineers installed an ECM-controlled oil pump that oils connecting rods directly. With the ability to electronically control the pump, oil ratios vary from 400:1 at idle to 44:1 at wide-open throttle. As a result, OptiMax engines use up to 50 percent less oil and run virtually smoke-free.
Introduced in 1995, Mercury's OptiMax direct fuel-injection system was a lead bull in the manufacturers' stampede toward cleaner two-stroke engines. OptiMax was not designed as a fuel system to bolt onto an existing engine, but as a new power plant to complement Mercury's line of outboard engines. Last year the lowest horsepower OptiMax available was the 135. For 1999 Mercury offers a 115 OptiMax. [links]
