Scarab III props
 

hey guys i just picked up a 1989 Scarab III with stock 365 Mags and Bravos. just wondering what a good prop would be. right now it has 23" Quicksilvers. i havent even had it in the water yet. i know the boat will not be a hard charger but would like to get the best prop on it for its current power. thanks all :cool:

Should be rite about there Dave... in pitch...experment with blades ..3 or 4 ...whin I switched from Mirage plus to Q-VI's...the hull seemed to handle alot better...Dave

Re: Scarab III props
 

I agree...I switched from 21" Mirage 3 Blade to 24" Hydromotive Quad IV's when I went up in HP. What a difference.

Re: Scarab III props
 

Thanks gotime...mine drives like its on rails...handles ALOT better...even the wife noticed it...

I would get a little seat time and then baseline your props and start testing props to see what props help you to achieve your goals.

thanks guys. i did take note of your recomendations from the other threads and will start with those. actually DMC i was gonna contact you as i didnt know what Q-IV was, not real familiar with what is out there. i see that it is Hydromotive Quad IV's.

Julie i will have the boat in in a few weeks and will get some base numbers to work with. what kind of prop is the quicksilers that i have? are they just an OEM type prop?

Re: Scarab III props
 

It's hard to tell which props you have. There are a number of Quicksilver prop designs out there. If you have what is typically referred to as a "Quicksilver" prop it is typically a common prop that is put on by OEM's and is sold today as the Mercury Vengence. It's a standard type prop that is a step above an aluminum prop.

GlassDave...I did alot of expermenting...I was even spinnin 25'' pitch Mirage plus...but couldent get to max rpm...we need to get sone of these Scarabs together on Lake Erie...I can count about 8 that I know of...you outta come to Mentor for one of the ZOO'S fun runs...great group...Let me know how your trials go...I might be able to get some different props for you to try...Dave :cool: :drink: :drink:

Re: Scarab III props
 

thanks Matt . . . i guessin the are the props that came on the boat.


DMC our big poker run is going to be run out of Put-in-Bay this year in july might be a good time to get some of these things together. cant wait to get this thing in the water. its going to be a great step up from my Scorpion.

i too have same boat and had 23 mirages. went up to 496ho's and 26 4blade bravo's but can only hit about 4600 r's. i guess i have to go back to 24's. i also love the 4 blades.

Re: Scarab III props
 

finally got the boat in and i ran 56mph at 5000rpm and 42mph at 4000rpm with the 23" quicksilvers. should i be able to spin a 23" 4 blade?

Re: Scarab III props
 

Dependant on the diameter of your 23P 3B's you may loose some RPM with the addtional blade. But I would guess that the diameter of your 3B props is smaller than that of the Bravo I 4B. THe larger diameter of the 4B will also decrease the RPM as well.

what would be a better prop the B1 or the Q-IV. i have been told the Hydro works well with this hull. what is the differance in the two props?

Re: Scarab III props
 

The Bravo I is a bow lifting propeller and the Hydro QIV is a stern lifting propeller.

Re: Scarab III props
 

I run QIV'S...boat handles 100% better...she felt slippery with the 3 blades...

Re: Scarab III props
 

its at the top of the list Dave. probably wont get a set till i freshen up the power though. yea my boat also feels kinda vague with the 3 blades too. may try a few different props with the stock motors just for grins. got a friend that has a few sets on the shelf for testing :cool:
