This is Complete & Total BS!

I know, I know.. I read it on the internet so it has to be true.

I am far from an expert but I have owned 7 Bullets and two Allisons over the years all with more than 250 h.p. I will tell you this... There are about 0.01% of all bassboats tournaments rigged that will run 85 mph.

It is painfully obvious that this guy doesn't have a clue about gear ratios, prop pitch, and rpms. When a manufacturer lists the gear case as a 2:1 ratio, they are saying the motor turns 2 revolutions for each revolution of the prop. On a 2.3:1 gear ratio it means now the motor is turning 2.3 revolutions per each revolution of the prop.

A stock Merc 250 ProXS comes with a 1.75:1 gearcase. You can order a 1.62:1 case like I have run on my last two Bullets. The 1.62 case is a TALLER gear than the 1.75, not a lower gear ratio. So running a 26 pitch prop on a 1.62 case is like running a 29 pitch on a 1.75 case. Get it?? The caveat here is that with the taller gear you lose holeshot. Kind of like driving a stick shift and taking off in 2nd gear...

This is a prop slip calculator from Mercury Racing that I use to figure boat speed, prop slip, rpms, etc.

To run 85 mph with a 16" pitch prop on a 2.3:1 gearcase you would have to turn the motor 15,000 rpm's! If the boat they tested had a 16" pitch prop like they stated and turned it 5,000 rpms like they stated, with a 2.3:1 lower unit like they stated, even with no prop slip (which is impossible) they would be running a BLISTERING 33 mph! This speed sounds about right for a 115 of any brand on a 21' bassboat.

The guy that wrote this article is a Moron!

WHAT IF!>... the bass boat was on a conveyor belt??? would it be possible?
