OK would love to hear anyone's experience with Gheenoe LT25 and Tohatsu 20 hp I am switching to a stainless prop and am thinking a 10 pitch (same as the stock aluminum that came with the motor) will be a good match. I am over reving at the extreme top end of my throttle. (probably last 300 rpms) The stainless should drop my RPMs 500 give or take. Has anyone else made this change?

Best bet is to get a tiny tach to get some actual rpm readings and buy from your local prop shop. Any good shop will let you try different props and tweak the final prop for you at no extra cost. I bought a hardline brand tiny tach and so far it’s worked great. I checked it against a tach gun and it was dead on. With small boats and motors, one inch of pitch on a prop can change your rpms by as much as 500

 

[Gervais]

Also, make sure your motor height is set correctly before dialing in your prop. That can change your rpms as well

Hey man, I got a power tech SRT for my 20, I wasnt quiet hitting the rev maxing at 5900 so I went down a pitch to a 9 SRT 3 blade. Fished the boat a few times this weekend and now Im spinning a tad to much, trimmed up and wide open I can bounce at that 6250 mark with any air. Im gonna order a 10 and try it should be just right.

Im not running a gheenoe, mine is on a 16 Whipray tiller, I also have the tiny tach, cheap and easy way to keep track of hours as well

 

[Flatbroke426]

Thanks everyone. I know about the tach was just hoping someone had gone thru this to give me a good starting point on first prop to test with the tach

 

[HPXFLY]

my 10 pitch shows up tomorrow, I will try to run that boat next week and report back.

Thanks. I look forward to hearing back. Di you get a Solis?

How did the 10 pitch work out?

 

[State fish rob]

Just a question , do five blade props add enough stress to prop shaft and related parts to cause concern? Ive read some horror stories. Seems to me a pitch problem , not the number of blades. Anybody running one (5 blade prop)?

 

[State fish rob]

^^^Don’t know how that happened sorry guys

I put the Solas 11 pitch on my 20 Tohatsu. I'm only pulling around 5800 RPMs . Now wondering if the 10 pitch would have given me more speed. I can run about 23 with just me on board but I'm carrying some weight, with IPilot and AGM battery.
I thought the stock prop was a 10 pitch, will look when I get home.

sm1444v. im 215 lbs. 45 lb agm battery and full 3 gallon tank up front, light tackle and light cooler. stock aluminum 9.25 x 10 was turning well over 6100 up to maybe 6260 at WOT. hard to get a consistent reading with the rev limiter. ordered a solas amita aluminum 9.25 x 11. took it out today and still hitting rev limiter slightly over 6100. thinking of trying same prop in 12 pitch. not sure if i should consider stainless.

The Lt-25 needs a 40 horse that is the sweet spot for that boat ...
find a Yamaha 2 smoke 3 Banger !!!

but an old tohatsu 25 2 stroke without a rev limiter also does well
11 pitch 4 blade powertech = 32 mph ;-)

Santee 160 here with the Tohatsu 20hp. Finally tried the Solas 11P stainless. My stock prop was aluminum 11.5P. Ran 23 mph gps with two guys, i pilot, full fuel and battery. I was only showing 5400 max rpm though. I suspect I'll pick up a couple more hundred running solo. Really didn't see any significant difference between the two props.

Santee are you located in SC? I'd love to try your aluminum prop on my 20.The stock 10 pitch red lined at half throttle and my SS Solas 11 only pulls 5400 RPMs. Hits about 23 solo and 20-21 with a passenger.
I'll be at Santee the week of October 6-11 is why I asked if you were from SC.

 

[Fred land]

Sorry, located in Virginia Beach. I'll try the aluminum prop next trip as I just installed the tiny tach. The 11.5 was the stock prop with the rig. I do not recall hitting the rev limiter with it.

 

[Searay]

Mine came with a 10 pitch which didn't work out. 3/4 throttle and it was done,

 

[bjtripp83]

12p aluminum right for me.

I have a Tohat 20 tiller on an FS-18. With my son (95 lbs) and me (165 lbs) I hit the rev limiter at 3/4 throttle. I have the stock 10 pitch aluminum on the boat. I want to order a new prop but should I get the 11 or the 12 pitch? I don't have a tt on the motor.
