Hey Walleyehed-another prop question

[sangerwaker]

Hi Kenny<br />Goat a quick question for ya or anyone else who cares to comment. I plan on buying a spare prop for more speed this spring and need a little advice on what to look at.<br /><br />Here's the setup-<br />Sanger outbaord tournament barefoot boat (my avatar) with 200 EFI Merc. Motor is mounted at lowest setting and I will not change that. It would screw up my perfect barefoot wake with my 19 High Five. <br /><br />I can turn about 5900 without touching the trim (full negative trim). I was using a 21 pitch High Five last summer and could easily turn over 6000 when trimmed up. I got about 60 MPH when alone with that prop.<br /><br />I'm thinking either a Turbo 22 pitch, or possibly a Laser II or Tempest in a 23 pitch. I would like to maximize speed. I wouldn't be using this new prop for skiing, so hole shot isn't too big of a deal. I think I can turn a 23 and be in my RPM range.<br /><br />What would you suggest trying?

Re: Hey Walleyehed-another prop question

First of all, all 3 props you're looking at work "best" at the surface....doesn't mean they won't work for your set-up, but some efficiency may be lost.<br />The high-5 works best "down-under" on sterndrives, and alot of heavier outboard apps, but works good for what you are doing.<br />If I could get my hands on a Turbo II in a 23....wait, I do have one.....I'd try that.<br />I don't know if a guy could get lucky enough to find one on ebay or not. The Turbo II has a smaller diameter and a little less blade area, and works well without surfacing.<br />My Turbos are consistantly faster than anyother props I own...that being said, I believe I would try a Turbo I in the 14-1/4X22...I'd say 23, but the lift of the Turbo is great enough it may cause problems when trimmed to proper RPM with the engine clear down on mounting height.<br />By the way, your 21 high-5 @ 60 is showing around 7% slip-quite good.<br />In general, stay away from the 4's and 5's for speed with engine mounted where it is (60 is cookin' though). They tend to work best, speed-wise at high mounting heights.<br />Before you make a decision, let me do a bit of looking in my data sheets....I'll edit back.<br /><br />EDIT: OK, let me see if I can get this to make sense...My 23 Turbo turns exact rpm that my 24 Raker turns, but the Turbo is about .5 faster.<br />I have a LaserII in a 21(most honest 21 by pitch gauge)it turns about 550 RPM more than Turbo 23, but alot slower over-all.<br />My point here is that the 22 Turbo will pull like most other 23's.<br />If I were to go with a 23 I would go with a Stiletto before the laserII, and I "think" a 23 Turbo I, is going to have too much bite, but.....I have been wrong before.<br />BTW, what is the approx weight of your boat???

FWIW - Have ProCraft 210 CC w/225 Merc using 23P 4B Trophy Prop. Will turn 61 GPS at 6k with 3 medium to heavy adults and 50 gal gas. Fair hole shot - going to put on my Torque Shift prop to check out improvements. Really like Trophy Prop - does good job

Re: Hey Walleyehed-another prop question

Thanks guys. <br /><br />Kenny, I had a Turbo I on my old boat and it was the best prop I ever tried...and I tried a lot of them. I just wasn't sure about it on my Sanger. Thanks for the info. I'll check back later.

w/225 Merc using 23P 4B Trophy Prop. Will turn 61 GPS

14% slip...not real good...<br /><br />Great hole-shot prop, but a 23 TurboI will walk off and leave it like it's setting still................Yes, I own a 23 Trophy too.<br />Matter of fact, at a high cruise @ 5000RPM, the 23 Turbo is about 4.5MPH faster in my application. (Deep-V)

Re: Hey Walleyehed-another prop question

Kenny,<br />Boat and motor are about 2000 lbs empty.

Re: Hey Walleyehed-another prop question

BTW, the 23 Trophy will be an ebay Item next week if anyone is looking...I'm keeping my flo-torq hub though..

Re: Hey Walleyehed-another prop question

OK, sanger, you're really light.....a 23 Turbo may be OK at that weight......I'm about 2000lbs as well, and I can spin a 25 Turbo @ 5400 at 3600ft elevation...I get about 5750 at Texoma....600+ above sea-level.

Re: Hey Walleyehed-another prop question

I'll bet your motor isn't mounted at the top hole either! <br /><br />Seriously, thanks for the info. Hopefully I can find a Turbo on ebay. I'll be watching closely and can hopefully get a decent deal.<br /><br />Thanks again Kenny!

You're right......it's about 1-1/2" BELOW the BOTTOM hole with the Turbo!
