Jet Pump Siphon
Is there any performance gains to removeing the jet pump siphon tubes?

I have no hard evidence that it makes any difference. However, I can tell you that they were eliminated on my Super Stock Pro 1200 so apparently, somebody believes it does!

You might gain a few rpm's, but probably not enough to tell the difference unless you are going for absolute top speed on glass.

That's one of the tricks the GPR guys use as well. Unless you're going for every last 10th of a mph, I say leave it in AND run an electric bilge pump!!! Never can be over-insured when you're on the water!!!

if you do remove them, grind them out, whatever, be sure to cap off the lines. do not leave it hooked up. if you kleave teh hoses hooked up, it can actually take pressure from your pump, like a cooling line, and fill you hull. ( bad).
without the tubes sticking into the jet, it will no longer act as a venturi.
