1956 Sportwin Diagram

[mrfisherman42]

Hi, I am replacing all of the seals in a 1956 Sportwin 10hp is there anyone that has a diagram or instruction sheet on how to tear this down? I am replacing all the seals and the impeller because it hasn't been ran in about 6 years. Thanks in advance.

Welcome to iboats.

What you need is a factory service manual, check ebay or outoboardbooks.com for a factory reprint.

There is also a thread in the FAQ here on iboats that you may want to read

you need a service manual, outboardbooks.com well worth the money, rather than making a mistake. there is nothing on line.

another at the same time.

MrFisherman,
Are you replacing the seals because they leak or what? If they're not leaking I'd replace the impeller and go fishing. The lower units on the '56 are just like the '55's through '57's, if that helps. Do you need a parts diagram or a step by step guide to the seal removal and replacement?

I am replaceing the seals because they are leaking. I was a mechanic years ago on automobiles so I might be able to get by with a parts diagram but I would love a step by step instructions on how its done properly. Any help will be greatly appreciated.

Its pretty easy, really. There are a few o-rings and a couple oil seals. You need to pull the driveshaft and prop shaft seals with a seal puller. I use a cheap claw style puller. You must also replace the shift shaft seal which is a severe PITA. I have used two methods for this. Either tap the brass bushing that holds the o-ring in place, thread a bolt in it and pull it out or use a 5/16" (I think) metal rod grounded down to 1/4" and pound it out from the bottom. I prefer the rod method. When replacing the spaghetti seal that holds the skeg to the lower unit make sure the grove is clean and apply a little silicone or sealer to help it seal. Also leave a little (approx 1/8") of seal overhang on either end. Too much overhang and it will pop out when you try to put it together. Too little and it will leak.

It is also helpful to use a jig to hold the lower unit. Mine is made of a short piece of 2x6 with a 2" groove cut about 12" into it.

Hey fisherman, I'd try and help but the man who taught me just told you how!
Those dang shaft seals are a pain! But I'm sure if I can do it anyone can!
Good luck,

Re: 1956 Sportwin Diagram

Thanks this should help alot. I had one gentleman tell me that I had to pull the powerhead to get the drive shaft out but according to this I don't believe so it looks to be splined like I thought it was. I will definatly take head of all your guys hints.

Don't need to pull the powerhead on the 10 hp. That's for the 5.5 - 7.5 hp. There is a shift rod disconnect as seen in the parts diagram.
