identifying prop
 

I have a 32 pitch merc 4 blade prop that was labbed by a unknown shop. It has a # stamped in the main body-3066 and a V stamped or etched in the area where hub goes,does anyone know who might have done it shop wise? I also have a 30 pitch merc labbed prop labbed by merc,it has a shinier finish than the 32 so I doubt the 32 was done by merc. Single v boat,runs 89.5- 89.7mph gps w/30 pitch at 5900rpm's w/boat 3/4 loaded down and 4 passengers,92.8 w/32 pitch at 5700 rpm's if load is light enough,other wise it just accelerates slower w/32 pitch and labors harder and runs about 89-90 at 5400-5500,any insight? I also have a merc 4 blade non-labbed 32 that just sucks all the way around,boat stern lifts,tq twist and is fairly sluggish,runs about 87-88mph around 5200-5300. I might get that prop worked for something in between my 30 and 32 labbed.Motor peaked at 944 hp at 5600 but barely dropped just a few hp until 5900 and tq peaked at 962 at 4500. I'm also running a stellings box with drive moved back a foot,I did have drive raised 1" above stock but boat cavitated around 3000 rpm's,blew prop out sometimes and porpoised from 2800-4000. I installed a 1" drive spacer which brought boat back to normal and got rid of all the nasty side effects of going up the 1",thanks,Smitty

If you get rid of your labbed 30, let me know. I run a labbed 28 now and would like to try a 30.

The 30 pitch has proven to be the best all around prop for my boat so far,the biggest thing I don't like is I may start out a day of boating fully loaded and towards end of day I get gas down to a third of tank and drop passengers off to go out and make a couple high speed passes and boat literally is on the rev limiter at 5900/6000 and it sucks to pull boat out just to change prop for a few passes,maybe labbing the 32 non-labbed to something 1/2 way between would work but it may be the 32 labbed I have is already that way,not sure,Smitty

Hey Smitty,
I am looking for a RH 32 non labbed if you decide you don't need.

The 3066 could be a couple things. The V is a pouring code and person at Merc.
