225 HO Etec ---- 28 Raker or 28 Raker II?

[Huntin 5]

Have you guys tried the two props on the same boat. What is the difference?

[200xp]

What boat do you have? I settled on a 29 tempest for my boat however I did run a 28 raker and raker II. I am no prop expert, however the II ran the same speed as the raker, but with less rpms and the holeshot was incredible with the raker II. Visually, it looked as though the raker II has more cup than the raker, which would explain the rpm difference I experienced. Just was not the right prop for my boat.

I have a Stratos 200ProXL.

I run a 27P tempest on my 21X triton. Best speed thus far is 74MPH and it performs real good with the etech hole shot is real good. I was looking into a back up prop for heavy loads probably a TRO4 27P.

The raker 2 has a little more"hook up". The whole blade is a differnt design.

I have the same exact setup. 200 pro xl and 225 ho etec with 6" jack plate. Im running 28 raker ll and only get about 5300 rpm max. Im going to go to a 26 raker ll and hope to pick up a couple hundred rpm.

Rude Dog,

What kind of speed do you get out of the 28 Raker II @ 5300 rpm?

[Jason Phillips]

Something is wrong with either the prop, motor height, or tach. That motor will spin that prop on that boat to 5700+. It will do the same with a standard 28 Raker.

At 5300 im running about 74 medium load 2 people live wells empty 1/2 tank of fuel

Agree with Jason. . . . . I have a 29 Turbo TXP on my ETEC and I'm turning 5500 at WOT, 76 GPS two anglers, 1/2 tank, and avg tackle. 78.9 GPS with just me.

There's some opportunity in the setup somewhere for some more r's.

the tachometer accuracy should be verified.
5300 looks like 100% efficiency. Can't happen.

Use this formula:
.0009469 X RPM X pitch X total gear ratio (.54) = theoretical speed - actual / theoretical = slip%
