We build bow riders for gigging the same way, if you don’t know what your doing it will throw you out

[@mritolduso7355]

As expected, the 3 blade performed better, especially on economy! Thanks Aaron once again for an informative video!!

[@KeyWestWaterman]

thanks for watching!

[@gradybrowning3976]

What a pleasant surprise, thank you Sir! 3 Blade for sure!

[@ranksadventuretv]

Even on a bad day, the view is spectacular❤.

[@johnnyvee9486]

Never would've guessed that the Gheenoe could go that fast! But I guess with enough motor, anything is possible. I love your work area, just pull into some random cove and change the prop! Very Dibbs of you. Cheers!

[@jjsager1]

Cool video Aaron

[@rumualdoviales2328]

What a view! Thanks for sharing!

[@rickshearer6359]

Wow!! That's a little DRAG BOAT!!! I RECOMEND A LIFE JACKET...AND A PARACHUTE...JUST IN CASE YOU GET EJECTED!!!! THAT'S FAST ON THE WATER!!!....I had a friend that had a drag boat....I went for a ride...one time only!!! We did 0 to 100mph pretty fast !! It scared me! It had a blown 396 in it...chrome headers....motor was custom built for it!!!

I am an engineer, so I love that nos. graph you did at the end of the video--easily and quickly informative. One thing, KZbin puts end screens at the end of your videos which blocked the graph content. I had to download a copy of the video (I have a Premium Subscription that allows me to do this) to see the full nos. spread on the graph. Downloaded videos do not have end screens. Apparently, only the content creator can control if these end screens appear.

[@mickemike2148]

Anyone else here that is nerdy enough to just love stainless steel props? Considering the fuel prices today, I'd say go for the one that give you the best fuel efficiency at the speed that you cruise.

[@KeyWestWaterman]

Strange looking set up.Reminds me of an old school Florida mullet boat.Good luck with that on a 2 foot chop.🤠

[@bjet80s45]

If you do decide to build a bow rider i suggest riding in a mullet/gigging boat first. They are on a whole different level of control from a helm and you better hold on....they will throw you out. Ive owned 5 gheenoes but this one by far is my favorite Aaron. You and Sammie built a fine machine!

[@plantzengineering9925]

I threw the numbers into Excel and plotted out the Speed versus RPM. The data shows the 3 blade will give you slightly higher speeds at the same RPM as the four blade. I'd assume that's in part because the 3 blade has less drag than the 4 blade. Great video, very educational! Thanks for sharing

[@plantzengineering9925]

The 3 blade needs about 3% less RPMs to achieve the same speed as the 4 blade.

[@Aaron_Hanson]

@@plantzengineering9925I imagine that it’s the extra blade creating slight cavitation so the reduction in rpm is a direct result of the ability the 3 blade has to gain friction. I’m no engineer but I have had my fair share of prop testing both driving and being towed by boats. I used to run a 23 pitch during races and a 21 during social season (both 3 blade).

[@plantzengineering9925]

That could very well be the reason @@Aaron_Hanson. I don't have the hands-on experience with testing props so I'll take your word for it. Very interesting stuff, thanks for the comment!

[@kaibryant8434]

Holy shi- your Gheenoe slides Aaron, kinda jealous tbh. Thanks for the knowledge on props tho, great video.

[@violetsydney4942]

3-Blade Propellers Higher top speed: 3-blade propellers generally have a higher top speed than 4-blade propellers. Better acceleration: 3-blade propellers also have better acceleration than 4-blade propellers. Less drag: 3-blade propellers have less drag than 4-blade propellers, which can lead to improved fuel efficiency. More efficient at higher speeds: 3-blade propellers are more efficient at higher speeds than 4-blade propellers. 4-Blade Propellers Better handling: 4-blade propellers provide better handling and stability, especially at low speeds. More grip in the water: 4-blade propellers have more grip in the water than 3-blade propellers, which can be beneficial for boats that are used for towing or carrying heavy loads. More efficient at lower speeds: 4-blade propellers are more efficient at lower speeds than 3-blade propellers.

[@hectorsuarez1227]

The choice is clear. 3 blade for the win 👍 The 4 blade did plant the bow a little better. You were hopping around a bit at top speed with the 3 blade. I’m sure it’s not a big deal at cruising speed.

[@Mike-hb4pc]

I'm pretty sure that could be remedied by trimming the engine out better. Maybe a set of trim tabs? (don't know how that would work on that kind of a boat though)

[@careaganwilliams2544]

Always good stuff!

[@tylersizemore166]

I’d love to see you do a flats fishing video for reds bone fish or permit sight fishing the flats off that gheenoe

[@MichaelSmith-uu2sw]

Not sure if you are reading any posts. Just got back from fishing outer banks in some wicked surf so just catching up on your videos. Was going to mention your last video when you were jigging. I starting using the Nomad Squidtrex Vibe lures while jigging and they have been money for me!

[@dhooter]

Tempest if you can find one are great at bow lift. Maybe a five blade also.

[@justdoingitjim7095]

The ads were blocking the lower 3/5ths of the readings. Only the top two were visible.

[@KeyWestWaterman]

I just fixed it! sorry about that!

[@tpelton]

i'll just throw this out there, but in aviation, the debate is usually 2 blade vs. 3 blade. and generally i think the wisdom is, that a 3 blade "grabs more" and so is better for takeoff and climb, but a 2 blade is better for go fast in cruise (once you reach your planned altitude and level off), and usually the reason cited is that less blades is less drag, so good for cruise, but, more blades is more "grab" which is better for getting off the runway and climbing. i assume boat propeller dynamics are similar.

[@robertfernandez3741]

Hey Aaron I love these type of shows I was wondering why you never talked about repairing your contender Love the show keep it up

[@JGrimm420]

You should tell the stories behind those fish tails hanging on that tree and include any clips of you have them. Love the vids

[@anthonyp2312]

Love 3 blades

[@jimrowland6089]

It looks like it rides well at 40 but I bet it rides a lot better at 25mph. I am in Bass Boats fairly often and hull design has a lot to do with speed and comfort. Boates that ride well at high speed don't do super skinny water very well. Still looks like Harley designed that one to have a nice helping of both worlds. Floats super shallow, stable, and handles a bigger engine just fine. Gheenoe is and will always be one of my favorite boats on the water.

[@francus7227]

If you fish artificial with a trolling motor.... and you want a Gheenoe 18' ..... Get the side steering.

[@goaski474]

Love to see you try out a Sharrow!

[@jimmyera3779]

Did you ever consider an outboard with jet drive vs traditional?

[@randaltotten9358]

They lose a little speed and Power but better for saving the grass Flats and manatees but don't do good with plastic bags

[@KeyWestWaterman]

alot of areas here jet drives are prohibited.

[@jimmyera3779]

@@KeyWestWaterman I was just curious. You seem like you do all your homework before a big purchase. I figured there was a logical reason

[@pain_weaver]

Jet drives are inefficient and have many issues. You can't just pop the impeller off and install a new one like a prop outboard

[@stevenratcliff8956]

You need bow lift. I’d try an 18 Raker v4. That’s the lowest pitch it’s made in Thing has super grip, you should be able to turn it 5700ish

[@luxorbill269]

4 prop looked smoother in the drive by. Cool and different type of boat. A lot of wind in your face at 43 MPH.

[@rickcreel3657]

the pitch has a lot to do with speed. getting the right picth for your boat maybe a challenge. maybe a prop shop can let you try many different pitches until you get the right one. i used a 9 pitch wide blade when hauling a load and a 13-pitch when fishing in rocky bottom.

[@michaelbrown1015]

Wanting stern lift on a bow heavy boat is the exact opposite of what you want for better handling and performance. You should easily be able to run a 17p 3 blade on there and have the power to spin. General rule of thumb wheh trying to get General similar performance from a 4 blade a 3 blade, as in comparable rpms at WOT is to go up a minimum of 2 prop sizes. ie, 15p 4 blade to a 17p 3 blade, and vice-versa. You should Always get a higher top speed with a 3 blade. Better hole shot with a 4. "Should" be better cruise economy with the 4 as well, but in that size/weight boat it's probably negligible, especially if the 4 blade is giving you more stern lift, which is further exacerbating your bow plowing. I'd be curious to have you try a 17p 3 blade. I'd also be curious to see how the boat would respond to dropping that thrust pin a notch at a time with the 16p and 17p blades, to see what handling characteristics become like. Great video and cool boat!

[@mod_incllc3235]

Slightly better MPG and top end speed with the 3 blade but from the video at least you were running nice and flat with the 4 blade and definitely porposing with the 3 blade.. Maybe just needed to trim down a bit.

[@THESLlCK]

That's terrifying I want to try it

[@michaelsachs-gp8qh]

😮 wow did not realize the bow dug that much from watching your regular vedios. It would have been nice to have the same camera angle on the two drive by's, but the 3 blade propeller bow shot the bow looked higher and the boat look like it would be more stable than the 4 blade propeller might be in choppy water.

[@MrJackg3]

My super 18 did 52 with a 75 HP. And I still had some throttle left it was sketchy! I can’t remember what pitch I was running I think 19 pitch.

[@vernongandy9026]

There might be a reason in the boating industry why the control console is not in the bow. I hope nobody builds an accident waiting to happen. As long as the water is glass, it is ok.

[@thesaurus688]

I'd try a 17p 3 blade Mercury prop. Probably get you the best mpg and cruise speed at 3500-4000 that your after.

[@KeyWestWaterman]

yea I was looking for a 17 to try, slightly bigger would push a hair faster/more efficient at cruise but lose a tiny bit of rpms at top end which i'm not concerned with. Hopefully can find one!

[@AngieWolfK72]

That’s pretty dang fast for that boat! You know what you’re doing but please be careful……….

When you showed us the results from the 4blade my guess was that the 3blade would do 44🤙 close enough lol

[@rowlandkimbrough6049]

Try a Mirage 3 blade 17 x15.5 before you decide on prop. Not sure if is made for the 90.

[@KeyWestWaterman]

thats what I have on my big boat, 225's I don't think they will fit a 90.

[@peterparsons7141]

Keep testing, the amount you sail your boat it will make a huge difference over the next five years. You rig runs good, but I think you can do better,,, try some extremes,,just to see. I’ve found that the documents just don’t cover unique configurations like you have. Plus it’s pretty cool when you find some combination that fits perfect.

[@mayhem035]

Used to sell props... man it's a .. based statistics to start from.. trials and ajusting kinda.. your dealers have to let you try 2 or 3 props to get the money.. we did that. No buying trail and error...depends of the set up. 4 blades alot of torq to the plane. Less speed.. 3 blades more time to planing more top speed... 🤷‍♂️👊👍❤️

[@juanziegler1471]

did you trim it out for top speed ? seems sad but weight of 4 stroke doesnt help yet its the future our 19 ft aluminum center console got 38 mph in trim w 70 HP 2 STROKE jOHNSON IN THE 90S

[@KeyWestWaterman]

standard.

[@stereolababy]

so you don't adjust the trim at all? like put it at 4k rpm and see if the speed goes up or down

[@KeyWestWaterman]

yea I was playing with the trim the entire time.

[@bobkirk942]

Like I said in a video what the hell they put a washing machine on the front of the boat lol😅😅😊

[@jimmycline4778]

That boat looks like it is very dangerous to drive, good to see your wearing your kill switch, I would definitely wear a life jacket especially driving this type boat!

[@rodneyalaking8241]

Running wide open, it looks like you’re off plane ever so slightly. Ideally, the back 1/3 of the hull should be touching water, front 2/3 not touching. If you could trim up a bit, first you will get the top of the prop out of the water = a few more rpms. At the same time, the bow raises up and there’s less hull surface contacting the water. Less drag, more speed, more agility. There’s a chance you’d porpoise some. Tabs would fix that. That’s my .02. Works with my boat anyway. I’m not an authority 😂.

So basically the 4 blade prop is marketing grift?! I thought the 4 blade was supposed to offer the best economy while sacrificing a little on the top end. Obviously boats are unique in the fact that no two boats are going to perform the same given different variables but from what you read or are led to believe the 4 blade prop on smaller boats is supposed to give a little more hole shot and fuel economy while sacrificing top end. Have you seen the Sharrow Prop???? Insane results but it's $5k for the prop. No joke. Thought it was a typo.
