Old Evinrude question, Can anyone help?

[merkinstine]

New day New problem! Lol I thought she was ready for the river so I was trying to test the motor out one more time and now fuel is pouring out the carburetor. Any ideas?

 

[merkinstine]

Could it be as simple as a carburetor rebuild kit? That's my guess

 

[airshot]

Probably float or needle valve....rptime for a good rebuild kit !!

Looking at the location of the Vacuum Cutoff Switch, I would say that is a 1955 25 hp

 

[racerone]

A 25924 is a 1956 model 30 HP

 

[jimmbo]

I couldn't find that Model # in any of my books, so I went went 55 25hp. As I knew the the Cutout was there on the 55
I know in 57 they had moved the Fuel Filter to the Port Side of the Block

Do you know what carburetor rebuild kit I need?

 

[merkinstine]

I think I found it 18-7043, does anyone know if I can take the hardware for the shifter cable off and switch it out to my new type 400 cables? It does not have an allen screw but a square sticking up on both sides next to the eye.

Hey guys thought I would show you guys an update, I got all the parts to hook it up to the boat ( the one for the life of me can't figure out what it is) have them all installed and took it out to the river yesterday after noon after rebuilding the carburetor and got through the no wake zone then hit the throttle and then clunk out of gear she went! Tried reverse and couldn't get it to work either. It did however limp back to the trailer at an idle. I'm thinking it's the clutch dog. does any of you gentlemen know what the part number is? I would like to order it before I take everything apart since it's the rainy season so it doesn't sit with the skag off. And if I replace the clutch dog would I need to replace anything else? Also do any of you guys know where I can download a parts list or manual? Thanks in advance you guys are awesome!

This for a 57 35hp. unfortunately the Site doesn't provide for 1956 models

I'm quite certain that the Gearcase and internals stayed the same between the 1956 thru 1965 model yrs for the Big Twin engine.

Jimbo thank you so much! I have had the hardest time fi ding parts for this thing. When I opened the skeg up everything locks together and spins when I do it by hand but the snap rings was broken. Is there any way that could be what's causing it to not go in to gear and stay in gear? Also would any 2" snap ring work for this or is there something special about it?

 

[jimmbo]

I believe the Snap Ring is being used a stop for the Trust Washer. If it that Washer moves, the Reverse Gear can move also, with not good results. If it the correct Thickness, I can't see why it won't work.
Yours does have a Tapered Roller Bearing at the Front of the Propshaft?

 

[merkinstine]

Also I bought a new oem clutch dog but I can't get the old one off, is it supposed to slide off easy or do you have to take the back baring that's pressed on off to get the clutch dog off? I found the whole assembly online for a "56 30hp lark 302520 375769 is the part number i belive would it work for my 56" 30hp big twin 25924 if I can't get the old clutch dog off? And thank you so much for your help this thing has been a journey, but after I get this figured out I will ha e replaced or put my hands on everything this motor has and it's a good feeling but has got me so anxious to get on the water! Also the motor I have is a

The difference between a Lark and a Big Twin, is Paint, a few shiny bits of Trim on the Cowl, and a Cover over the Choke, Mixture Knobs, and Cowl Latch

The Clutch Dog on a 56 should just slide off, forward or backward. Does it slide back and forth on the Splines?

I think so, I can post some pictures when I get off work and let you see if you think I need to get new gears and such. How did you do a search like that on that website.

It will slide back and forth bit stopps right about an inch before it comes off the splines.

 

[merkinstine]

I couldn't tell if the splines were a little boogered up or if it was designed for it to only come out the back. I really hope it's just that snap ring but I found the whole assembly for 200 dollars and the person says it works perfect almost like new.

 

[racerone]

Snap ring is special.----Has a bevel on one side.----Can only be installed one way !!

Racer would know. Last time I had one apart was in July 1972, My dads motor

 

[racerone]

Bearings are NOT pressed in place on those !-----Clutch dog slides right off.-----Well it should if there are no burrs on the spline.
