Description 




Our 540309 Jet / V-Drive fresh water header is basically the same as our 540303 Jet / V-Drive fresh water header, except for the overall width, which is 33", and mitered collector. Designed with a narrow overall width for tight motor box configurations or for twin engines applications. A short or angled valve cover must be used. This header must be removed to adjust valves.

The header incorporates a 2" primary tube (1 7/8" I.D.) The 2" primary tube header has been Dyno tested with our 632 cubic inch Chevy test engine with outstanding results.

The standard collector length is 8" and mitered to point down at approx. 36 degrees. In many Jet and V-drive applications where there is extra space between the engine and transom, this can be used to add collector length to help combat reversion. Keep in mind, that if the exhaust tips are below the water line, the header can literally pull water up from outside the boat.

Camshaft selection is very important to guard against reversion. Lightning has many camshaft and lifter options from mild to wild. We also have dry tail pipe extensions that can eliminate reversion completely.

The standard Header comes with a black powder coat finish; optional colors available. The headers come complete with water supply manifold, gaskets, bolts, pet cocks, water feed hose and clamps.
