Got a free Sportwin

[scoots]

I helped a fellow pull an old aluminum boat and trailer from out of a blackberry patch. There were 2 long shaft outboards mounted to the boat and another long shaft in the boat with a short shaft Sportwin (1971 9122R). He couldn’t use the short shaft, so he gave it to me for lending him a hand.

After I got the Sportwin home I pulled the cowling. YIKES!!! It was one gigantic chipmunk nest.

I hooked up the shop vac and cleaned up all of the chipmunk’s efforts. Now, things are looking salvageable. Surprisingly, the carb had no chipmunk residue. I pulled the plugs, which were a little more than finger tight and sprayed some Deep Creep into each cylinder. Before I laid the outboard down for the Deep Creep to do its thing I thought I’d try to turn the flywheel by hand. It turned with ease! I couldn’t try the rope start as the rope is broke and there is no handle.

Question – what diameter and length of rope should I get for this 1971 Sportwin? I’ll check for spark once I can get a rope for this outboard. If no spark – I’ll probably part it out.

2nd question – the stern bracket was all the way up (had probably been that way for years). After much effort the only way that I could get the stern bracket down was to depress the ratchet spring with a screwdriver (part 35 in the image) so that the swivel bracket ratchet (part 36) would disengage from the ratchet wheel (part 53). How is this supposed to correctly disengage?

If I can get a rope and handle tomorrow I’ll check for spark, more questions coming if I do.

Thanks for your expertise

I can’t help you with question #2, but the rope diameter should be 7/32". Get at least 72" of length, and you should have enough. Sorry I don’t have a more exact spec. Hopefully someone else will come along with a bit more detail.

Scoots,

The tilt mechanism on that motor is a bit more complicated than most. There is a lever on the Right side, #16 in your pic, near the shift lever that needs to be pressed to release the motor back to a down position. I forget exactly how it works, but you have to lift the motor and depress the lever at the same time.

If I remember correctly, you also need to have the motor in Forward or Neutral to lower it. Might be wrong there. More help will be coming.

People either love those or hate them. I am in the former group. A bit under powered for a 9.5, but neat little motors and the price was right.

Couldn’t find the rope in the 71 parts book, But, according to the 70 book, the sportwin uses 65.25" of 5/32" rope, that comes from spool part number: 772577.

Any lawnmower shop will have that diameter rope.

OK, I pulled the flywheel and adjusted the points on the Sportwin, The coils look new (???), I never expected that! One coil is green and the other is black. I have spark coming off both wires. I had to wrap the rope around the flywheel to pull it and check for spark, because the recoil spring is broken – now what can I do? It’s around $78 for a new recoil spring – OUCH!

Suggestions???

Is the recoil intact, just with a broken spring? If so, look on ebay for a spring or try the classifieds….

You can post an ad here in the Free Classified section, find a donor motor, or do some internet searching for P/N 0314587.

I found a new one for about half what Marine Engine wants for one.

A free Sporttwin is a good find. I bet the thing will fire. I wouldn’t buy a spring just yet. You may be able to fix the old one. I have fixed many broken ones through the years.
