PLM Pro Throttle Bodies are designed to be used with factory intake manifolds as well as aftermarket Intake manifolds for bolt-on horsepower and torque gains by optimizing engine airflow, all at a competitive price.

The B-Series 74mm throttle bodies are 14mm larger in diameter than the OEM 60mm throttle body. The throttle bodies are precision die-cast from high-quality materials with an idle adjustment screws for fine tuning. Each Throttle Body features an oversized bore, which results in significant horsepower gains throughout the power band on naturally aspirated applications and even more on forced induction ones. This results in a larger opening for incoming air and dyno proven 15+ WHP gains (modified engine with port matched intake manifold opening). Some vehicles may require customizing of coolant lines. We recommend port matching the intake manifold to have the best result.

Good impeller kit
Great kit for impeller alpha one gen two outdrive. The only thing that was missing is the instructions as a reference.

Outboard impeller replacement kit.
This kit was for a 1999 Mercury Force 75 hp outboard motor. I purchased used and had not been run for a year. Impeller was hard and not flexible enough to pump water. The kit fixed that problem and the job took about 2 hours to complete. (I took my time). If you don't have a shop manual look for YouTube videos. I watched several and found one that matched the motor I was working on. Made things much simpler.

Excellent product
The water pump kit fits perfectly well on my 1997 Alpha 1 Gen+ Stern drive. Quality looks good and at reasonable price. I run the motorboat for 20 minutes and the water recirculation was constant
