Im looking to buy a prop for top end speed. Im currently runnning a 28p Raker. The prop is dinged up quite a bit but I can still run 72mph @5800-6000rpms. Im looking to get a prop for speed and playing around. What are you guys recommend/what are some of you running? hat can I expect for speed out of this thing? Thanks, Kyle
If you're turning a 28p prop on a gambler at 5800-6000. I've gotta couple of questions for ya'....
1.) is the prop missing a blade or two?
2.) what tha' heck kinna motta do you have on that thing? More so... what lower unit/gear ratio?
You supply that information and you'll get the information you're looking for.
1999 Evinrude 225
Lower Unit 1.82 gears I believe (whatever stock is)
Turning a 3 blade Raker 28p at 5800-6000rpms
Im just looking for more topend out of it.
I went on mercurys website and put in all the info, boat weight/motor/gear etc etc and it said i should run a 29p Temptest. Only thing is I dont wanna buy a merc prop and have it re-hubbed. I mean if thats the ticket then fine Ill do it but theres gotta be a evinrude/johnson prop out there that'll work decent.
You can purchase a hub kit for it if you get a merc. prop. no problem there. They're not pressed in and they have kits for OMC and Yammies... among others.
But something ain't right - IMHO... I've got a 2009 225 Pro XS on a '95 209 and while set up isn't completed it's running 80 mph @ 5600 turning a 27p trophy.
On Mercs. prop selector guide what information did you put in? Namely what hull weight did you enter? No way you'll turn a 29p Tempest with a stock OMC 225 - even if it's HO anything.
I'm not big on OMC's but for the most part I recall their recommended rpm's being closer to a max. 5600.
Here's what I'd do if I were you.... start off bolting a 26p trophy on it, play with the engine height and see what you get. That prop you have now has to be wacked pretty good to let you turn those numbers.
I put in
1250 hull dry weight
505 engine weight
250 me+gear
1999 Evinrude 225
And I got 29p temptest?
I have a hub kit, not sure if it will go in a merc prop but its the "flo torque" design.
I have the book on the motor not 100%+ but believe my redline is 6600.RPMS, I will double check.
Thanks For help....
My 97 209 is in the 1650 to 1700# range. If you have a 1250# hull in a 2100 gambler she should haul a$$.
Yeah I want me one of them thair 1250# 209 hulls too! 1650# is the correct entry.
If you have a 1999 Fitch the rpm range, according to one web site, is 5-6000rpms.
I'll be realllll suprised if you can turn that 29p Tempest much above 5000rpms. Let me know what your hole shot is like.
If you're talking about the hub kit that came with the prop.... that fits a mercury engine - exchange it for a OMC kit.
Good luck n' let us know the outcome!

Not quite sure why turning a 28 on a Gambler would be so unusual; I turn a 28 Bravo to 6200 on my 2100.....now I do have a 250 but I'm sure there are plenty of guys turning 28's with 225's.
Al.... he's in a '97 209 w/1999 225 fitch. Oh... never mind you seem, for some reason, determined to contradict things I say. Your board... your choice. Funny thing though where the heck are your helpful hints for folks looking for answers? Only time I seem to see you is when.... well you get the picture. Why don't you offer up suggestions for the guy?
So you're turning a 28p bravo @ 6200.... Add an inch for cupping and you have a theroretical speed of 97mph. How close are you getting to that? Knock off the added 1" pitch and your theroretical speeds drops to 94mph. How close you getting to that? What kinna lower unit do you have on that 250? Have a hydraulic jackplate? You throw out rpm and prop pitch without GPS numbers - meaningless.

You might want to do a trial with a 27 pitch Renegade Bass. With an OMC engine you could use the older rubber (pressed) hub or the newer TBX (removeable) hub. On my GT183 the Renegade Bass has very good lift and great hole shot. The Renegade should be a sturdier prop than a newer Raker prop. Good luck.
ok..i am going to put this out there, so maybe you can lighten up just a little with the feedback....i learned a long time ago not to doubt anything if you haven't seen it yourself...i know some boys with some badazz 225 cowlings on their motors...but the truth is that something isnt right with that setup...a 225 stock ho, aint going to spin a 28 raker, or for sure a 29 tempest...and the hull weight is 1650 to 1700...
that prop has been depitched, or the tach is wrong...and i just replaced mine, because it was reading 8000 at wot....
LD
LD.... the reason I got my panties in a wad is Al has had a habit of making comments like the one he made here to things I've posted. And then I question him on it and there's no response. It's getting old.
We figure the same.... I figure Al has a 83-84mph boat. 85-86 and maaaaaybe 87 is about all you're gonna wring from a Gambler with a stock 225/250. Just a fact of life. Most are gonna run in the 81-83mph range with a good set up. A whole slew of'em are gonna see 78-79 on a daily basis.
As for the original post... Stock gearing on that engine is 1.86 vs 1.75 for the Pro XS soooo he could probably turn a tad larger prop but I wouldn't think, even with that gear ratio, he'd spin a 29p Tempest very high.
OK sooooo Im wrong. All i can post is what Im seeing in the boat. Maybe the tach IS wrong. Maybe the prop has been de-pitched. I dont know....I just want to get the F N boat running at full potential. I got it last November and I got what I got. When I first started running it it handled like chit. Then I added some more setback to it. Im now at 13" setback which I think is a little too much but I dont have the money to buy a 12 or 10". So its either 13" and it handles good or 6" and runs like chit.
I posted this to try and find out what i SHOULD be running and what EVERYONE ELSE is running. Not to be told the #'s dont add up. I KNOW THE NUMBERS DONT ADD UP or I wouldnt have posted looking for HELP!.
-- I dont have nitrous.
YB - you should be OK with the 13" plate. What mounting hole is the engine bolted to the plate? I've got no experience with OMC's but... with 3.0L Mercs. if you had the stock gear case you needed to stuff'em down in the water to get'em to work. With the torque master you need to run'em much higher.
My boat is in Florida getting "healed" and set up with the '09 225 Pro XS isn't complete. The XS is a torque monster but with summer heat the last time out I was spinning a 27" Trophy 54-5600 maxing out at 80.02gps. My first Gambler was a '96 209TE with 225 2.5 ProMax. That combo spun a 26" Trophy at the limiter of 6750rpm and was good for 80-83mph depending on water/temp. conditions. Early in this thread I recommended you try a 26" Trophy. I did that not thinking of your OMC engine. Sooo.... if you wanna bolt on a Renegade that'd probably work too. The Tempest/raker will be 1-2mph quicker(maybe) but the boat handles and turns better with the 4 blades. The bravo prop Al mentioned is a really good prop for a Gambler if speed is not your main consern. The bravo will be 1-3 mph. slower than a Trophy/Tempest or Renegade/Raker.
you are good with the 13 inch setback...and if i can be of any help to you i will meet up with you when i get a day off...i got a couple of props that might tell you which way you need to go...i would also look at sending the raker to mark croxton and have him clean it up and dial it in for you...he can tell you the true pitch of the prop when he gets it...you just need to start finding some new wheels to put on the motor to try..my first choice would be a raker, followed by a croxtonized tempest...
LD
Thanks everyone.
LD I'll be hooking up with you sometime I'm sure. My prop (i believe) is un repairable. I will post pics Friday.
Im looking for SPEED out of whatever prop I purchase. The 28 raker Im running now Im content with for tourneys and regular fishing. But when its summertime and Im up in SC on Lake Marion running a cigar boat with the ladies on it I wanna smoke em.
my set up is close to yours i am running an 97 intimidator with a 225 3L EFI Merc in arkansas spring fall and winter turn a 27 tempest 79.2 GPS at 59 to 6K summer i am running a 26 fury at 77.2GPS and can over rev it set where the tempest runs but the hole shot on the 27 is horrible when the weather is hot.
man...if its still got the blades on it mark can fix it....
and i am heading to marion myself in mid october...
LD
LD - Let me know when you head to Marion. My dad lives 1 blk away from Harrys Fish Camp on the Diversion canal. Depending on where your headed Maybe we can catch up around there. Ill be staying at his house whenever I go up there. My b-day is Oct 10th and Im trying to get up there the weekend of or following.
Ill post a picture of my current prop and you all can take a look at what I got. Im sure it can probably be fixed but my thing is.... Fix it for X amount of $$ or buy another one....
Does anyone think Ill see 85 out of the rig or no? 80 would be about tops.
Good to know Im ok with the setback. I sure do have a hellacious holeshot, Even without trim tabs.
no...you wont see 85..unless you bolt on a 300...
i know a couple that are running 77 to 78...may hit 80 on a cool winter morning with a light load...but thats still haulin it with a 225...i think i get to marion on the 14th or 15th....maybe i will see you there if not before...
LD
