Ok rather than debating this anymore

Well then STOP debating. I gave advise, you gave advise (then had to debate) and now someone else is giving advise (and you have to debate). Just because you keep saying the same thing over and over that doesn't make it right.

The OP has the info now, let HIM decide.

Troll.... :roll:

Why worry about the solenoid at this point? You can apply and release power and watch it actuate.
At worst you can always disconnect the solenoid powered choke and use the manual. It's not like it's needed at WOT (at least not when the carb is functional :LOL2: ).

And here's another possibility, that the carb they put on the 1982 E35ECND (#393057) is the exact same carb as on my 1982 E25CNE (#393017). And that the power difference between these 2 particular engines (aka MPH/RPM) is derived solely from having different pistons, crank, gear case ratio & prop pitch. I wrote boats.net & asked them after seeing all the part numbers between those 2 carbs are the exact same. If so, then I'll just buy that carb & CS I found new and call it a day. We'll see.. [-o<

I am not Rich......and my "rather than debating" comment was not directed at you......nor did I imply that it was directed at you. Your response was a trolling statement....period.

The crank and pistons are not different Bloodstone. The gear case and ratio is in that year though, but has nothing to do with HP that the engine is capable of (prop pitch can be changed by you accordingly depending on load and RPM you are running). If I still had that 85' 30hp I would send you the carb for FREE just to prove I am correct regarding this mod.

Sure it wasn't - well humor me then....who was it "directed" at? (And I'm talking the 1st time you said it, not the 2nd time when you didn't want to debate with B2F, who had posted almost the exact thing I had posted)

I post, you reply (mentioning my name), I reply back and then you reply back with "I have no need to continue debating...."

Boys, boys, boys! [-X ............................................ :lol:
Anyway Johny25, your "modified" motor is/was a 1985+, correct? Isn't 1985 the year they started making all the significant changes in those engines & measuring HP from the prop instead of at the head? Mine is a 1982 25hp (#E25CNE). And from what I gather here, there appears to be ALOT more involved with trying to convert a 1982 25hp JohnnyRude to 35hp (or 30hp) than it is a 1985 & up 25hp JohnnyRude.
When you mentioned you had "walked others through it", were they pre-1984 25hp JohnnyRudes or post 1985 JohnnyRudes?
If it's the former, I'd like to see the posts/links or be able to contact them for info. And FYI, it's NOT because I don't believe you, I just want to see for myself what such an undertaking would call for mechanically speaking.
 
Oh my gosh, you guys are blowing up a simple carb swap like it's major port work or something. ](*,) If you can't figure out that a 25hp and 35hp carb throat is a different size and your to cheap to buy one just to try it then stop debating about it. I've seen guys put a 90hp carb on these motors and run them. He didn't see the gains hew wanted but he made it work. Omc use to make a race motor called the mod 50 and it was a 3cylinder based on the 49 cube 60-75hp motor and it had 3 90hp carbs. keep in mind a 90hp only uses 2 carbs to feed 4 cylinders. Those carbs are 2 barrel carbs so each throat feed one cylinder and they used them on a 49 cube 3 cylinder. Honestly don't think your going to over carb your motor and worst comes to worse sell the 35hp carb. I'll bet money your 25hp carb is different then the 35hp carb. Major changes engine wise happened back in like 72-73 they went from 22.somehting cubes to 31.8cu.in. Sorry for the rant but this this horse is getting beat to death here. If you don't try you'll never know.

You're right Li' blue BUT, keep this tidbit in mind..that 35hp carb ISN'T free.
So without sufficient & specific information, it's a $140.00 GAMBLE/guess. Now, $140.00 may be peanuts to some here but, not to me because I just don't have money to piss away all willy nilly. And according to boats.net, if both carbs are not the same then why is the housing the same size & why do all the parts have the same part #s including the intake?
It's not like I expect everyone here to do my homework.
Believe me you, I've been calling & emailing different marinas & dealers trying to get info (not just here or at iboats).
 
https://www.ebay.com/itm/35hp-Johnson-carburetor-/291057369059?pt=Boat_Parts_Accessories_Gear&hash=item43c45effe3&vxp=mtr $32 buy it, a rebuild kit and slap it on. There's no way I'd pay over $50 for a carb never have never will. If you watch on ebay and know what your looking for you can find them cheap. Buy the carb or keep beating this horse doesn't make a difference to me. Good luck with the motor.

Ummm..thanks I guess. :-s
1) My exact carb is a #393017. The used carb you provided the link for is for the 35hp & comes with NO CS.
In short, I don't need someone else's possible junk. What would be the point?
2) The carb I am looking at is the exact same carb (#393057) BUT, brand new with a brand new CS.
3) It's only "beating a dead horse" when you already know the answer/outcome for 100% sure.
I don't due to all the conflicting advise given; "Oh yes, it'll work!" Or "No it won't work because of such & such.." And all the head-spinning contradictions in between. :shock:
In short, I want a definitive answer on why it will or won't work. If not from you, then somebody else (doesn't necessarily have to be here @ Tinboats).
Cheers!
 
Post a pic of your carb throat front and back. Some one should be able to tell you what you have. Yours might already have a 35hp carb, the 25 and 35 carb might be the same for that model. If that's the case they probably have the same large throat carb. I've seen enough omc single barrel carbs to tell if it's got the smaller throat like the 25hp 31.8cube,40hp 45cube, 60hp 49cube and 56cube motors use. Or the larger throat used on the higher hp models of those 3 motors. Sorry if I've sounded rude but it just seems to be blown out of proportion here over a carb swap. I really do hope you get your motor lined out nothing more frustrating then chasing down a problem with these things.

Contact shawnfish on here......he did an 80 or an 81 I believe.......
 
No point in buying new......I paid $40 bucks I believe off of ebay for the carb and intake together. This really has been blown up to be way to much. Only you can decide if it is worth it. I created my original post to show others that you can squeeze more HP out of these motors for a relatively cheap price....meaning under $100 and you can do it yourself with a simple bolt on.

And like lil blue has stated....we do not know what you really have? Heck I haven't even seen a pic of said motor....let alone carburetor......for all I know you have a black motor :lol:

Good luck Bloodstone....and if you follow through post it for others that may have an 82' and want to do this

Well for one, the boat & motor are currently in storage for the winter at my fishing buddy's barn. So no pics at this moment. Heck, I haven't even posted any info or pics on my completed modified Meyers semi-v that I finished last April that the motor currently sits on :oops:. And no problem Lil' Blue, :beer: I understand all to well getting exasperated (one of the reasons I left imdb.com boards). Anyway, I did manage to email 2 separate individuals on Ebay one with the 1982 #393017 25hp short shaft carb & the other the 1982 #393057 35hp carb and....I am happy to announce that according to both individuals, the throat size on BOTH are approximately 1 3/8" (maybe 1 7/16" ). They showed me pics with a tape measure included in the pics. BUT the important thing is, they're apparently the same carb! \:D/ . Don't know about jet size yet. To answer your question Johny25, the motor WAS steely aqua blue(?) but some idiot painted it white & put a Johnson cover on it. But it is an 82 Evinrude (according to the metal tag). And I am going to buy the new carb (comes with a new CS too), plus a new intake gasket because I want to eliminate ALL potential problems. Thanks btw, I'll contact shawnfish asap. Happy Happy Happy!
 
I am curious to know where they took the measurements from.......outside, inside (where it bolts to intake) or internally.....the actual throat/venturi? I have yet to see the same size throat/venturi on a 25 and 35hp in those years so I am skeptical of what they are saying.

If you got pics from the guys then post them :)

Not to scare you bloodstone......but I have found many misrepresented parts on ebay and other sites for used parts.....carbs especially. Many people will sell a carb under the 35hp tag when it is actually a 25hp carb and one of the reasons is because the carb works on both models. I found this same problem when trying to find a 15hp carb for my 9.9 johnson. BE CAREFUL and do your research thoroughly. I can visually tell a 25 from a 35 now and a 15 from a 9.9 if they give good pics posted of the throats.

Can't post the exact pics he sent me (tinboats doesn't allow cut & paste apparently). I could maybe forward the emails to you Johny..
Anyway, here's the ebay link to my 1982 carb(#393017 25hp)

https://www.ebay.com/itm/1712159135...em=&sspagename=ADME:X:RTQ:MOTORS:1123&vxp=mtr &
https://www.boats.net/parts/search/BRP/EVINRUDE/1982/E25CNE/CARBURETOR/parts.html

And here's the 35hp 1982 carb #393057
https://www.ebay.com/itm/291057369059?item=291057369059&viewitem=&sspagename=ADME:X:RTQ:MOTORS:1123&vxp=mtr
& https://www.boats.net/parts/search/BRP/EVINRUDE/1982/E35ECND/CARBURETOR/parts.html
This ISN'T the one I am getting (that one is new with a new CS)
 
Ok, I finally said to heck with it, went over to my fishing buddy's house & dredged thru all the snow over to his barn. I pulled the cowl off my 1982 25hp & looked at the carb (took pics to, but they came out crappy because the camera I was using was crappy).
Stupid question time: Where would the model # for the carb be? The only # I saw was on top of the carb body & it was # 324441. And upon researching it on boats . net, that # came up zippo (went from 1978-1984)! I am beginning to suspect (much to my chagrin) that I MAY HAVE a "Frankenstein Motor" (aka a true "JohnnyRude" cobbled together one piece at a time). It has a johnson cowl & is painted white with some blue showing through where the paint chipped off & a Evinrude metal tag reading # E25CNE.
I hope I am dead wrong on this.

SumDumGuy » Mon Feb 03, 2014 10:42 pm[/url]"]For that p/n I came up with the following:
https://www.ebay.com/itm/Johnson-Ev...tor-18-20-HP-1969-76-Pno-324441-/250631061711
This is what I see for
E25CNE 1982 CARBURETOR
Tag Part # Description
0393017 0393017 CARBURETOR ASSY., 15in. transom
0393020 0393020 CARGBURETOR ASSY., 20in. transom
https://www.evinrudeonlineparts.com/OemParts#/Evinrude/E25CNE_1982/CARBURETOR/28115/44091

It's NOT the 1st one that is for sure. I already knew it was SUPPOSE to have the #393017 carb (& it does resembles that one).
And I'll have to go back today, retake those carb pics & re-look for the model #.
Then look for the power-head serial #(dark in my buddy's barn-no electricity).
But thanks for the heads up. I'll let you know what I find.
