Prop Reccomendations Please... 90 Scarab 454 Mags
Hello.
I am running 3 blade 25's and not happy w/ acceleration. Some are recomending 3 and other 4 blade.
Now when I accelerate, The tachs on the 454 mags are only @ 4,000 rpms full open and cruising which I know is hard on the engines... What should I run for a lil better performance???
Also... where is the best place to buy props... and should I go used??
Thank you so much for your advise!

need more info
what size boat,drive ratio,what prop?
4000 rpm's is to low for that motor. you should be in the 4600 to 4800 rpm range.
try a mirage + 23p.
also post this in the prop section you will get more help. Call brett at bblades or julie at throttle up both are members on the board. Good luck.

BTW, 4000rpm is way too low for WOT. Either you have the wrong sized props or your engines are real tired and in need of a rebuild.
