Introduction and looking for prop advice

[No Way II]

Just joined to today! The amount of info on this forum is awesome.

I have a 31' Fountain TE with twin 225 Optis. Boat's name is Bam Bam. It's a knickname I've "acquired" b/c I tend to break everything I touch.

Right now I am running 14.25 x 21 Turbo Props. I had 14x 23 offshore series but the 21's have helped me get the rpms up, better cruise and better lift. I am looking for a RH Rev 4 21 (got the LH already). I noticed the blades on the Rev 4 are huge compared to the Turbos.

How does labbing affect the Rev 4s? Is it to remove the cupping? I guess I need to try a stock pair first anyway. Right now, I run 58mph WOT with 3 fat guys 2/3 fuel and gear.

Thanks

you will probably loose some RPM with the Rev 21s, the Revs are a very heavy prop for there size so they are significanytly lightened during labbing

are the off shore blades 3 or 4??

[No Way II]

The offshore series are 4 blades.

The Rev 4s have more blade surface and cup than the Turbos. Once I can get my hands on a RH Rev it will be interesting to see the difference.

DO YOU HAVE JACKPLATES OR TRANSOM BRKT OF SOME SORT?
ARE THE MOTORS BURIED DEEP ?
IF YOU CAN GET THE MOTORS UP A LITTLE (ONE HOLE) IT MAY HELP SOME, HARD TO SAY WITHOUT A LITTLE MORE INFO.....:thumbsup:
WHAT RPM ARE YOU GETTING WITH THE TURBOS AND CURRENT SETUP?
AND RPM WITH THE OFFSHORE SERIES?
IF THE REV 4 BLADES ROB SOME RPM ....
1. RAISE THE MOTORS "IF YOU CAN"
2. GO ON A DIET "BOAT" " 3-FAT GUYS" "GEAR";)
3. HAVE THE PROPS THINNED AND BALANCED "LAB FINISHED"
COULD SEE AS MUCH AS 200 RPM FROM THIS.:thumbsup:
COULD DO THE SAME WITH THE OFFSHORE SERIES PROPS IF THEY AINT TO BANGED UP OR WELL USED.
A GOOD MATCHED PAIR OF BLADES DIALED IN BY A GOOD PROP GUY IS PRICELESS!!!:cheers:
BE SURE TO TEST THE PROPS AS CLOSE TO THE SAME CONDITIONS YOU RUN NORMALLY SO YOU GET AN ACCURATE RESULT.
WHAT IS MAX RPM FOR THE OPTI MOTORS ????
I WOULD WANT TO BE RITE @ THE LIMITER WITH A LIGHT LOAD AND LOW FUEL SO WHEN YOU GET HER LOADED DOWN SHE'LL STILL BE IN THE CORRECT OPERATING RANGE EX: 5800-6200 OR WHATEVER IT IS FOR THE OPTI'S.:cheers:

The Rev limiters kick in at 5750 for these motors. I havent been able to run light in a while since I top off each time. The Turbos are doing well but I want to see if the Rev 4s perform better and I want a spare pair of props anyway. I should be able to hit about 5700 with the Turbos real light and trimmed out.

The offshore series (Vensura) props I had were labbed but the diameter was a little small. The Turbos lift the boat much better. The engine height is right, I just want the best performing 4 blades for this set up. I know the Rev 4 might drop my RPMs a little so maybe labbed is the way to go. Right now I have an unlabbed LH and am looking for a RH.

The only dieting my fat ass crew and I do is to drink light beer.
