Black Manifold-Dual Flange Bolt Pattern-1.82L Volume-8.72in. Long Runners-74mm Inlet w/B Series T/Body Bolt Pattern-2pc. Design. The engineers at Skunk2 Racing have worked tirelessly to develop the next generation of high performance intake manifolds and are proud to announce the release of the much anticipated Ultra Series Intake Manifold. Years of R&D have culminated in a multi-piece cast aluminum intake manifold that offers advantages that only a modular design could allow. Building upon the performance legacy of our Pro Series Intake Manifold, as well as using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a three-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum and optional plenum spacers. In addition to CFD testing, the Ultra Series Intake Manifold has undergone extensive in-house dyno and on-car testing which has led to a design that is less restrictive, yielding both torque and power gains well over many of the competitors. Detailed and meticulous planning went into every aspect of the Ultra Series Street Intake Manifold. Ultra Series Street Intake Manifolds are manufactured from cast-aluminum high-grade 356 aluminum alloy for lightweight yet added strength over sheet metal manifolds. Each manifold is CNC-machined for a precise fit, and individually inspected for quality assurance. The Ultra Series Street manifold features a generous 74mm throttle body opening and is constructed with thick walls and entry minimizing concerns of breakthrough when port matching. Intense planning and design went into the plenum (1.82L plenum volume) to distribute even airflow to all four cylinders under dynamic load conditions. Placement and design of the velocity stacks were rigorously flow tested to ensure maximum delivery of air to the cylinder. Large velocity stack raised bell mouth entries lead to long 221.5mm intake runners with smooth transitions allowing the Ultra Series Street Intake Manifold to outflow the competition.

2nd time purchasing this item. The 1st one lasted 2 years, but my boat hasn't been used a lot either. The marine mechanic who replaced it for me said it was definitely time to replace it. He said it fits and works just fine. Has good water flow. As for quality and value, I'd say decent. The price is better than an OMC OEM pump. I plan on using my boat more this year, so we'll see how it holds up. I'll get it replaced at the end of the year. Ease of installation, NOT EASY. The lower unit has to be completely removed from the outboard. Some outboard are easier than others and as old as this one is, it's probably easier than some of the newer ones. I've watched a couple of videos on YouTube on how to do it and I might try to do it myself next time. It cost $360 to have it done and that's with me supplying the pump. He said it took him about 1½hours to do the job, but I was charged for 3 hours labor. Probably what the book shows. I'd buy it again and I'll try to do the job myself.
