Turbo hot shot prop for 20 HP

[racefan2]

I have a 20 HP evinrude with TNT and am in need of a prop as it was just tuned up ( just purchased motor) and it has a spun prop as it is slipping a good bit. I have a 10 1/8 x 13 and it runs well with this size but if I am getting a prop I am going stainless. I am looking at the Turbo Hot Shot for the OMC 20 - 35 HP motors. Any body here have this prop or know somebody that does. What about the Cabelas stainless props for the small outboards? Is there another prop in stainless to look at also?

Re: Turbo hot shot prop for 20 HP

Hi Scott, I have tried a Turbo Hot Shot on my Johnson 50 HP and was not that impressed. I ended up going with a Power Tech propeller. You might have better luck with it than me though. Propellers respond differently on different hulls. I ended up getting my Power Tech online for $169 from Midwest propeller.<br /><br />All the details are in this post http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=40;t=000010

Re: Turbo hot shot prop for 20 HP

I had just finished reading that thread right before posting. The big difference is my 20 HP and yours being a 50. That is a different bore and stroke just to start so it is somewhat hard to compare but I am going to look into the prop you pruchased some more.

What about the Stiletto triad prop. Here some information<br />Stiletto Propellers are truly the stainless edge. All Stiletto Stainless Steel Boat Propellers have a progressive pitch design.

Re: Turbo hot shot prop for 20 HP

I have read the Stiletto is a good prop. I have no experience with it my self. Walleyehed recommended the Hot Shot over the Stiletto for my set up, he does have alot of experience with different props.<br /><br />I am pretty sure most modern propellers have a progressive pitch. All the ones I have tried did anyway.<br /><br />It is hard to compare one set up to another. The best way is testing different props. Unfortunately this costs money.<br /><br />Good Luck keep us informed<br /><br />p.s. check out KIGUY52's post in this thread, http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=40;t=000114 he has had good luck with a Ballistic on a similiar set up to yours. Alot of guys on this forum don't like the Ballistic, but I have read some reports of them doing very well compared to other props.

Re: Turbo hot shot prop for 20 HP

The Triad is very simular to the Turbo Hot Shot...<br />One item of interest I've found on the Hot Shot is it's a hell of a prop on a flat-bottom where alot of lift isn't needed.<br />As we found in Fisherman38's case, it didn't have enough diameter or lift for his application.

Re: Turbo hot shot prop for 20 HP

Fisherman38 has mentioned the powertech prop and I have looksd at them. They are 260.00 polished from powertech I beleive for a 10 x 13 which I feel is a bit steep for a 20hp prop. Midwest has a satin for 202.00 less a 20% discound which is not bad butI want a polished prop.<br /><br />Walleyehead what do you think. My boat is a semiV which can be seen in my advar. I can post a photo of boat from back view 3/4 view so you can get a idea. The 10 x 13 OMC stock ? PROPS LIFTS THE BOAT WELL just seems to slip a good bit and does not bite at WOT and turning.<br />I am also not sure what size to go with as I get 5000 to 5100 now 1 person but it drops to 4000 with 180lb person ( prop sliping ?) or to much pitch?<br />My boat <br />as you can see there is not much V there<br /> http://i10.photobucket.com/albums/a142/racefan2/ebay001.jpg <br /><br /> http://i10.photobucket.com/albums/a142/racefan2/630735cf.jpg <br /><br /> http://i10.photobucket.com/albums/a142/racefan2/c255aeab.jpg

Re: Turbo hot shot prop for 20 HP

I got my Power Tech from Midwest, if you pay through paypal you will also get an additional $15-$20 off. You have to read the fine print. I got the 20% off plus another $15 for paying through paypal. That is of course if you have paypal. They also offer free shipping in the U.S., to bad for me I had to pay $31 shipping (Canada)<br /><br />They will polish the satin prop for an additional $30. Atleast I was offered that. I got the satin finish, it just looks as though it was sanded with sandpaper. I kinda like the look. It is sanded in the direction water flows over the prop. I doubt polishing will help any performance wise with your 20 HP, but hey for $30 it should look alot nicer.<br /><br />Jason

Re: Turbo hot shot prop for 20 HP

That sounds good as I use paypal so that just sweetens the deal some more.<br /><br />Fisherman 38 can you post a photo of your boat so I can compair hulls

Re: Turbo hot shot prop for 20 HP

Racefan2, where is the AV plate in relation to boat bottom when the engine is in the level position...the photo appears that the AV plate is higher than boat bottom by quite a ways?? Am I seeing things?????

Re: Turbo hot shot prop for 20 HP

Hey Scott, I almost couldn't find you a pic with a small enough file size to post. I found one the dealer sent me when I bought the boat. I also found one online from another boat. Same model and hull. <br /><br />Heres mine,<br /> http://www.myfishingpictures.com/watermark.php?file=527/8009Picture025.jpg <br /><br />I should also say that my motor is now mounted one hole higher than this pic shows.<br /><br />Heres the other boat, not my boat.<br /> http://www.myfishingpictures.com/watermark.php?file=527/8009Angler3.jpg <br /><br />Jason

Re: Turbo hot shot prop for 20 HP

Notice in the second pic where the pitot tube and transducer are mounted???? That's about 6" too close to center...bet it vents on left-hand turns..

 

[racefan2]

Re: Turbo hot shot prop for 20 HP

Yes it vents on left hand turns but only on a hard turn.<br /><br />The second photo there is only a transducer and my livewell pickup and drain. both of these were factory installed.<br /><br />Which plate is the AV plate. If it is the top plate it is about maybe 3 inches above the bottom but the plate right above the prop is only 1 inch above the bottom.<br /><br />another photo from a different angle<br /><br /> http://i10.photobucket.com/albums/a142/racefan2/d4753d84.jpg

Re: Turbo hot shot prop for 20 HP

Kenny may be refering to the second picture I posted. Seeing as you do not have a pilot tube. The second picture is not my boat, It is a picture of the same make and model boat just for hull comparison. My pilot tube and transducer are not that close to center. I agree with you though, they do seem kinda close especially for a boat set up by a dealer. You would think they would know better.<br /><br />Scott the AV plate(anti ventilation plate) is the plate right above the propeller. This is desigened to help stop ventilation by blocking air from being sucked from the surface into the prop blades.<br /><br />Jason

Re: Turbo hot shot prop for 20 HP

racefan2, in your pic I see the CMC has the engine lifted quite a bit for the HP available.<br />If it's not venting, that's good, but to make it run better, it's gonna take a good prop. Good bite with minumum thickness blades.

Re: Turbo hot shot prop for 20 HP

Kenny,walleyehed <br /> <br /><br /> I have some more photo's I just took before I cover it for the winter snow . <br /><br />What prop would you think the POWER TECH OR THE TURBO HOT SHOT, I am leaning towards the power tech now but will lissen to your oppion as I really cannot afford to play the prop switch around at this time.<br /><br />photo with straight edge to show height of caviation plate to bottom of hull Motor is trimed all the way down up about 1/4 inch for storage.<br /> http://i10.photobucket.com/albums/a142/racefan2/boat007.jpg

Re: Turbo hot shot prop for 20 HP

Any suggestions walleyehed for a prop to use?

 

[walleyehed]

Re: Turbo hot shot prop for 20 HP

If the plate you laid the straight-edge on is parallel to boat bottom, or "trimmed neutral",<br />I'd go with the larger diameter prop, due to the heigth of the engine.<br />Nothing wrong with a powertech, satin or polished... you'll gain 1/8" in diameter with the Turbo or stiletto, but I'm not sure which has more blade area.<br />Based on RPM figures you listed, which-ever prop you choose, I'd take an 11P over the 13 due to it dropping so far by adding 1 person.<br />In this case, I think the choice is too close to tell which will be best (Turbo, stiletto or powertech) because I think they all will be very close in an 11P.

 

[racefan2]

Re: Turbo hot shot prop for 20 HP

walleyehed <br />Just one question on the rpm drop could it be prop slip because of the added weight as the OMC dealer that tuned the motor took the prop off and said he can see where the prop is slipping as it is leaving marks and it really don't matter the amt of weight either as my father is 180 and my fishing buddy is 300 and I get the same 4000 rpm with either person in the boat.<br /><br />How much speed will I loose going with the 11 pitch as the motor has a rev limiter at 5200RPM I beleive.

 

[walleyehed]

Re: Turbo hot shot prop for 20 HP

You may have cavitation burns, but I doubt the hub is slipping...prop slip is different than hub slip, in which case the RPM is usually quite high with less fwd speed.<br />Your engine does not have a rev-limiter to my knowledge and the RPM range should be around 5500-6000RPM. At 4000, you aren't producing much HP or torque. If you go to an 11P I think you will get back close to the top portion of the torque curve, so I don't think you will lose any speed with a load. 5200 is too low with just you in the boat. I think you're getting the same RPM figure with either person because you are pushing so much water and with the engine loaded down, it has no torque. You are running a 20 on the same size boat I was running a 40 on, and the best I could swing and get the RPM needed was a 12P.
