What is the diff between a chopper and cleaver

[kevlar3000]

What is the performance difference between a cleaver and chopper prop. What is the best application for either. I have a Merc V6 150<br />on a Glastron Carlson CV 16. With Aluminum 23 I run 62 @ 5200 rpm, the normal range is 5000-5500 rpm. I have no Jackplate or set back. Looking for a recomendation for<br />a ss speed prop.

Very cool boat.<br /><br />A chopper refers to an over the hub exhaust, 3 blade round ear prop. Bow lifting. Stock Merc choppers usually slip badly getting on plane. <br /><br />A cleaver blade is straight on the trailing edge and comes to a point. Stern lifting. <br /><br />If you are looking for the ultimate speed prop with the least amount of test time call Mazco at 636-343-9911. Ask for John.<br /><br />Good luck!

Thanks Dhadley,<br /><br />I got real lucky with this boat. It is in real good shape, I picked it up from a Merc mechanic in Wisconsin, was his own boat for the last few years. Motor is real strong, and she sparkles forever. My situation is this, I am gonna have to find a used prop in the 200-250 range, I unfortunately don't have the 600-700 to do it right. I figure if I search around enough I can find a good compromise, get me to 65 mph without breaking the bank. I will probably e bay it as there are some decent prices to be had. I have been told the Lazer II is a good prop. But am interested on some more ideas. I can handle sluggish plaining as I have a good ski prop.I don't wanna waste your friends time if I don't have the cash to really do it right.<br /><br />Thanks again,<br />Kevlar

I may have a 3 blade 23" SS Stiletto for a Merc V6 that was run in a test. It's not hurt and is as new that I would take 250.00 for. List on it is 397.00.<br /><br />There may also be a 4 blade prop around also. If you are going to get a jack plate I would strongly suggest a 4 blade. They're more money but well worth it. <br /><br />If this fits your needs let me know. Thanks.

If only an hour ago.... I have an ebay bid on a Merc chopper that ends Friday. If I lose the auction then I am very interested. I will let you know, and really appreciate the help. This hull is really a 60 mph hull so I figure a jack plate may push more than this boat is suited for. If I can zoom in the 65 range I am a happy man.<br /><br />Thanks,<br />Kevlar

That boat will run in the 70s np. You will have to raise the motor up on the transom to do so safely however. You may want to put a tourqe tab on it for the high rake props. Makes the wheel feel lighter when driving.<br />Nice ride,a friend of mine has one.

Hey Thanks Corm,<br /><br />I know the boat has hit 70 w/ out lift with a ballistic 21 @ 6000 rpm. I don't wanna push her that hard so I am looking for a 22 to put me in the 5500 5700 range. Wifey says prop ok but have to wait till the budget allows for setback$$$$$. Tell me more about<br />the tourque tab? Where does it mount, what do they cost ect. Be great to lower steering pressure a bit!!<br /><br />Where is your friens located with the CV love to chat with him. Is he registered w classicglastron.com? It is a great site!!

They mount on the skeg. Cost is around $15<br />the best money you'll ever spend. I've been running them for 20 yrs on most every motor I have owned from a 20 Hp on up. My friend lives here in Eau Claire, but doesn't own a puter. Just hot rods and boats. <br />corm
