'59-18-fastwin sat for years

[imported_tweeter]

model 15028-07596
replaced impeller, although old one looked o.k.
took carb apart, has cork float-seems good, all needles and seats are clean, one coil is all cracked, other one seems newer but has some minor discoloration, how can it be checked?, points are servicable and condensers well how can they be checked. Seems to me that the boys working for Ole used the same coils/points for all their small motors but different condensers, why? Lower unit was dry but spins quietly, should it be opened up or just add hypoid?
Replaced all fuel/air lines under shroud. Tank is spotless inside.
Under shroud it is so clean you could eat off it. Don't think this baby has many hours on her. The tiller bracket is broken just in front of the fuel connector on the motor and it leads me to believe that this happened soon after the motor was originally purchased and it was just left to "rot". Is the bracket made of aluminum and if so can it be TIG welded?
Thanks Tweeter!

The handle is aluminum.

The carb is probably OK, if it is clean. The cork floats were troublesome.

The impeller may look OK, however they do take a set and it should be replaced.

The points and condensers are OK, just set the points to .020". Use Champion plugs only gapped at .030".

The coils do crack over time. If they work (provide spark) run them. They are available ,many places, like here on iboats, for reasonable prices.

The lower unit is probably OK. Just refill it and make sure you replace the fill/drain plug seals.

i'm running a '55 15 rude, parts laingsoutboards.com if you don't see what youneed o the site, call Jim he'll find it.

Original coils had two different thickness of laminations, more magnetism induced from the flywheel in the thicker ones. Hence, two different condenser capacities. Aftermarket stuff is one-size-fits-all, sorta.

Do you just want to patch it up to "get it running", or do you want a super good-running, reliable motor like Evinrude is famous for?

Are your coils both the same color? If they are, they are the same age and the other one will be cracking soon. OK, I'll catch heck for saying this but if you are looking for reliability give the "good" coil a whack with a screwdriver handle. If it shatters, it was going to anyway. Good ones won't break.

Points get dirty, oily, and corrode as well as wear and pit. Look at them and decide whether to clean or replace them.

Condensers very rarely fail totally shorted or open. But they most always are at some state in between and will usually work, though not necessarily well. Since they are cheap, and old, why not just slap a couple of new ones in there. You will get better, hotter spark and better points life due to less points arcing and burning.

There's no problem having that bracket TIG welded.

I've wondered about the condensors too. Some of the smaller engines turn just as fast as the big ones (5000 RPM) so I think it must be the differences in flywheel magnets. There were P/N changes in the flywheels that seem to match.
Your engine calls for the 580321 condensors. I think Sierra ignores this distinction.

EDIT: Too slow... There's the reason.

Re: '59-18-fastwin sat for years

I started to put the parts and years together, but decided I have better things to do. Anyway, there were several years that they used 580197 thick coils and 580422 condensers in larger motors, and 580416 thin coils and 580321 condensers in smaller motors. Then they went to thin coils across the board and 580321 in small motors and 580422 in larger motors. But not all models made the switch at the same time. There may have been flywheel changes at the same time they started putting thin coils in the larger motors, I got tired and quit looking.
