LH or RH Rotation & Prop?? HELP!!!

Ok, I am trying to experiment with props but I am a little confused over what I am looking for.

My motor is a 1995 Mercruiser 454/ Bravo 1, it says that it is LH rotaion on the cover, BUT I am pretty sure my prop turns clockwise. Wouldnt that be RH rotation?

I have to know what I got before I can try out props !

Thanks guys.

Also, should I try a cleaver? I have a 23p RH Cleaver froma friend. I heard they need high RPM's to hook up. I just have a basically stock motor with a 4400 or so RPM redline.
You have a standard rotation engine, so yes, you need a RH prop.
The cleaver style prop should give you higher rpms versus the same size prop that is cupped.. my boat came with a cleaver, but I changed it to a standard SS 3B to drop my rpms and I Gained about 1 mph at 200 less rpms when I did.. but every boat is different, and wont hurt to try it out since it's a free loaner.
Thanks! I'll give it a try. One more question, should I be looking for a 14 1/2 or 15" ? Make a big difference?

No, not a Huge difference, just keep in mind the larger the diameter and/or more pitch on a prop will decrease your rpms, so your ideal prop, when you find it, will take you to your max recommended rpms at Wot.. whatever you do, just don't over prop and drop your rpms too low, or you will lug the engine, but I doubt that will be the case for you, with the size prop your trying..
