I ordered prop on July 5. It was supposed to be in stock....it wasn't. I wanted it for a vacation...it was not here on time. It was not shipped on the subsequent date stated at backorder notice. I still have not received it (July 25).....yet I get email to review the product 2 days ago.

The 17 Pitch prop worked perfectly for my 18' Tiderunner with a 90hp Honda. Max RPM at 5600 WOT pushes it along at 40+ mph. Well worth the money spent!

I have an 18 foot sea ray center console (very heavy boat) with a Johnson 185 V6 (over powered by 45hp at the prop). The previous 14.5x19 gave 6-6200rpm and 42-45 mph. I wanted to drop to around 5500rpm but had no idea how going from from 3 to 4 blade would effect rpm so I went with the 14x19 just to try it out. The first thing I notices was how much better the boat handled and tracked. With the three blade at idle to about 10mph the very deep V hull would slightly "wallow" from side to side regardless of trim or loading. The 4 blade tracked straight as an arrow and gave almost 1mph increase at idle. On plane I was surprised at the amount of bow lift. Not quiet as much as the the 3 blade which was kinda ridiculous for a center console with such a deep V. The previous prop left about 3 feet of the hull in the water, this one leaves about 5 feet. My rpm drop to 52-5300 rpm and speed dropped to 40-42mph with the same loading. I haven't ran the prop enough to compare gas mileage but I don't expect that the mileage will change by much. I assume that the wetted area of the hull will negate the rpm drop. I was previously averaging 2.75-2.9mpg with about 40% of the run time being at full throttle, 55% with the throttle backed off to around 5800rpm and 39-40 mph. Medium turns with full trim and speed previously resulted in mild cavitation. This prop gives no cavitation at full speed turning sharp enough that there is enough side slip to make me nervous. I was amazed with quality considering it is aluminum. They aren't lying when they advertise stainless performance at aluminum prices. I doubt I'll buy another stainless prop as long as they keep making these.

New ss wheel gives better top end speed and better reverse handling characteristics. Not dramatic changes but significant with small engine.

After running about three hours, I can tell no difference between this propeller and the original propeller for my Mercury Bigfoot 60. Which makes this an excellent propeller! Installation was a snap!

I received my order in 2 days in perfect condition. It was exactly what I ordered. I didn't expect such fast service. Thank you very much.

Ok, i need a Hub Kit for the prop i just received from iboats.com. The https://www.iboats.com site states: "See Turning Point Selection Chart or the Prop Wizard", but neither are found anywhere on your site pages, (GRRR!!!) Also: it would be very easy for your webmaster to create "hy[er links" out of these two phrases: "Turning Point Selection Chart" (can be a link to the actual chart), and also " Prop Wizard" can also be made as a link, where clicking anywhere on either of the two words "Prop Wizard" will also take the customer to the actual Prop Wizard tool. Hire mgrs that know technology please! i need a hub, today ... but was not able to order it here, WHY?

I've been struggling to get my '06 Bass Tracker pro team 170 TX moving with a 9.9 merc 4 stroke (10hp limit lake) I've been through several props, 4 blade 5 pitch, 4 blade 6 pitch, 3 blade 7 pitch, 3 blade 8 pitch, but this mercury prop in 3 blade 6.5 pitch has got the heavy boat moving the fastest so far.

Good day, I have a 22 ft. Ebbtide 224 Catalina with a 5.7 260hp mercruiser. This prop looks great and what they say about the prop may interfere with the trim tabs is true. I thought they meant when you install it you may run into problems with the trim tabs. What I did not know was they meant if you use the trim tabs when you're trimming the boat, you could lose control of the steering if you're running full throttle or WOT. I was very disappointed when I briefly lost control of the boat and had to back off the throttle and explain what happened to my wife and kids and friend. I guess I learned a hard lesson that day. If you have to replace a prop get the same one your boat came with. Just make it stainless steel. On the positive note the prop gave me a constant 1 mile per hour more on top end. I'm gonna test this prop to find the best characteristics for my boat. (I have too it's the only one I have) I'll write a follow up review if it gets better.

The order page was very Precise and helped a lot with the order process to get the right prop the first time. It made the ordering process much easier. The prop and hub came quickly and fit the first try. I am very pleased and will use this service whenever I need anything in the future.

Order came in 1 week to Canada was worried for a bit because no tracking info after it shipped to Michigan. I believe it has nothing to do with iboats. Canada post lock out/strike looming might have played a factor. Thank you iboats order came well packaged and looking forward to testing my new prop. Thank you Mr.Cook for your effort.

I have not received my prop yet to rate it but I have to tell you that the shipping from this company leaves a lot to be desired. When I first placed my order, it said that I should receive my package by the 20th, the package didn't ship until the 20th! I placed my order on the 15th and it took them that long to ship? Very disappointed.

I bought this prop as a spare so as of yet have not used it. The online ordering was easy, the shipping was on time, and the price was competitive. All in all everything is good.

So I am writing not to say quality and delivery was s problem I'm concerned because when I went to product suggestion I chose the ser 26 and ran it one day changing everything as far as height and passenger load I only could get a decent run alone I forgot what I just bought and came back and ordered a 24 ballistic. Can I possibly return the 26 or get credit for a 28 semi cleaver for that is what I've now been told will be best for my set up. I hate to have 1000 $ in props and still no better than the stock 4 blade any help I'm running a GT 200 on a 20ft tunnel hull and loosing speed and bite each time. Thanks.
