I have a 20hp Suzuki and purchased a spare Solas Amitas 3- 9.25 10p supposedly exact OEM replacement but Suzuki oe prop performs better out of the hole AND top end.
I just ran the same tests on my new suzuki df25. 11 pitch stock. I also got the exact same speed with a 12 pitch Solas as stock. I used way more fuel and had less performance with the solas prop. I weighed these 2 props, and the the stock prop was 2.2 pounds and the solas was over 2.4. The difference in partial, is the rake on the Suzuki prop is different. My motor had plenty of power to turn the Solas, but for some reason got the same speed as the 11. I'm staying with suzuki props even at the higher price. Don't believe it's your motor, try a Suzuki and you will be surprised. Your engine also will get more power as you approach 25 hrs.
Your rpms were probly lower on the 12p makes your engine work harder... if you lost 250 rpm thats why probly the same speed and increase in fuel consumption.
Hey man. I just got my first boat and trailer in middle of COVID (April 30th- 16ft v-haul aluminum). No way to get them registered (DMV being closed) yet. Big part of me buying Suzuki 9.9 was your first video. Got myself a Suzuki DF9.9BTHL2 (electric start and and power tilt model). For some reason this motor came with 4 blade, 10" dia and 5" pitch. After some my own research, I bought same prop in this video as upgrade. I'm going to break it in according to owner's manual with OEM prop and post you my finding after I do the upgrade. Hopefully DMV open soon...
i know im late but bore out the restriction plate for more airflow to bring up the rpms a bit.. dont drill it out too much, small increments till you get where you want it
Hi! Can you please tell us how big the difference is when using the 9.9 ECU VS the 20hp ECU? Is It only the rmp that is higher, or do you feel the extra power all the Way?
Yes im saving the 11 prop for when i turn it in to a 20hp .. i need to make new video ..showing how i drilled the restrictor plate a little so now have more power guessing 12hp and im running 21 mph
LaingEj you can also fully remove the restrictor plate. Will give you the power of a 20hp, but you may hit the rev limiter (because you have a 9,9 ecu).
@manylandy_fan i know i tried .. i left the restrictor plate and drilled center hole little by littlet till i get now almost 5700rpm and 21 mph. I do hit redline with the 9” prop sometimes and 4900 rpm with the 11” pitch and same speed 21mph
Yuo sure have interested me in Suzuki what’s the trouble and the weight ratio . I love the 11,or the 12 . Quiet lower rpm greater long life in your engine easier to talk to people . Saving for a 9.9 . How much is the kit to change 9.9 to 20 Hp. Love your son trying it out . Happy New year Johnnie
I have a Suzuki DF 9.9 with electric start and power tilt. Just ordered the 20 HP ecm and flame arrester you ordered also. What prop is best for you? The prop I see online is 10 1/4 inch diameter and 11 pitch? Thanks, Jack
How do you know the rpm? Adjusting the pitch by 1 inch adjusts the motor’s WOT RPM by 150-200 RPM. for suzuki 9.9 optimal rpm is 4,700-5,700 so 9 should be perfect
@@laingej Yes, you can overcome hull speed with more hp. But there is not a direct ratio. The law of diminishing returns. Double the hp and increase speed a third. Double again and you might get another third. Double again, and you explode!
@@robbhawks2568 lol. I have no desire to go any faster. In fact 24mph is like the fastes this kaboat can handle safely. It would take off from the waters surface
Hi I have the same motor running 20 ecu on a 1648 tracker grizzly. I am only getting 18 mph speed with myself and a passenger onboard. Do you have any tips to optimize speed? How fast do you think it should be able to go? I am thinking of installing this 11p prop and adding a jack plate but scares to drill the holes in the transom.
@@patrickthomas3207 did you take the restrictor plate out of the motor? Shouldnt be able to run the 9” prop without over-reving. If you have the 20hp ecu take the restrictor out and try a 10” or even 11” prop
@@laingej the 20 hp restrictor plate (mesh) is currently installed. Last I checked I was around 5900 rpm wide open throttle. Thanks so much for the tips.
@@laingej cavitation plate is level with bottom of the transom, I am thinking to use jack plate to get it up about 1.5 inches and then try 10-11p like you said....it seems much too slow for the power of the motor. You suggest to remove the restrictor plate just to confirm?
18 mph is fast enough for that type of boat. With that 11 inch pitch, you are luggingbghe motor and it will have a short life. You should probably stay with the 9 pitch.
Takes a big man to leave up an incorrect choice in propeller but I guarantee someone will learn from this thank you for sharing 👍

Agreed. I've had better better performance with the stock 11 pitch all the way around.
Have you ever tried a stainless prop?
@@chilic82 no, but I’ve wanted to try one.

Awesome man enjoy let me know how it runs.. the 4 blade supose to be good for heavy load has more trust but nite as fast as a 3 blade
@@laingej Hi mate, where could I find a 4 blade 11 pitch propeller for my DF15A (upgraded 20)? Do you know any reference? Many thanks
@@olivierpeyrebrune4168 i buy my props online on ebay. Some offer international shipping
have the same Suzuki 15hp, which blade do you put on?@@olivierpeyrebrune4168
If I have more weight in the boat, is a 9" or 11" propeller better option? I have a 4.5 meter boat and 15hp suzuki with 4 people in the boat usually

11 pitch is too much for a 9,9. But you have the “upgradable” 9,9 motor, that can easily be upgraded to 15 or 20hp, which suits a 11 propeller better.

You can dril a bigger hole with the 11 pitch prop
In the restrictor plate

why dont u try a 4 blade prop
Who makes your engine stand and we’re did you buy it? Thanks
Oh man! It was a company in canada! But then went out of business was lucky to get one of the last few. Got it thru ebay.. no lowger available
I got mine off amazon, still available

His boat weighs nothing, a 9" would probably have it hitting the rev limiter
I got a tachometer intall i can just read the rpm. Yeah 9.9 is perfect for the 9.9hp
You are experiencing hull speed. In order to exceed the hull speed you need a lot more hp.
@robb hawks yes when i tried this prop with 20hp i reached almost 27mph
@@laingej Yes, you can overcome hull speed with more hp. But there is not a direct ratio. The law of diminishing returns. Double the hp and increase speed a third. Double again and you might get another third. Double again, and you explode!

Will you upgrade your motor 20hp?
I will but when i get another boat. Its fast enought on this inflatable its only rated for a 10hp
Oh nice. I will follow you, i hope you may upgrade your motor.
I will and will make a video
Thank you. Good luck
I did and didn't gain any top speed. Put a 10 on and found a good medium.

Did you get any noise with this prop ? Check my videos and I posted the noise.
No , no noise it was quiet but i got more splash into the boat and sucked air and certain rpm taking off
How did you know the RPM after changing the propeller
I hava a hardline tachometer installed on the front of the motor.. watch my other video tach/hourmeter 👍

10 pitch would of do the trick
