My '58 Sportsman w/K motor is eating condensers--get fire in and out of coil, points firing, no fire to plugs--replaced EVERYTHING-- enjoyed a blissful morning run on glassy Lake Greenwood, went to load onto trailer, wouldn't crank! Got home, same scenario, good fire everywhere except to plugs. Chatted w/old friend who's worked on every engine known to exist--said condenser's bad--replaced condenser, fired right up! Another fabulous morning on Lake Murray, same thing AGAIN, had to go swimming to load boat--any ideas?

yep, I have an idea: the trash quality foreign condensers on the market today. I don't have a solution...perhaps someone can recommend a reliable brand/manufacturer?

Would be interesting to learn what happens when you try another brand of condenser. Please advise. Also, please indicate sources of condensers if the manufacturer is the problem; I have a 'K' engine also. Thanks

ASK for it
Expect to pay 50% more. You'll save that much in aspirin.

While you're at the supply store buy a couple of spares! Easy enough to change should you have another on-the-water failure!

I had a similar experience some years ago. Without telling a long tale the problem turned out to be the contact between the condenser body (ground) and actual ground. I sanded the breaker plate area under the condenser mount to bright metal and the connection between the breaker plate and the distributor body. My problems went away. I have found that tend to have moisture accumulate undet the distributor cap. My engines are 327Fs with Prestolite distributors

Had the same trouble with condensers a couple of years ago with my W's. Also had a set of points spring break.
My solution was to change to Pertronix ignition that I purchased from Fine Wood Boats.
Good Luck!

Are you sure you have the right condenser for your distributor? They are not a one size fits all and most parts places are not going to have a listing for yours.

IAY-4009 distributor for 95 hp K motor--NAPA has 'em listed under a Sierra number

I would be very cautious with that NAPA. See the current Sierra catalog. They don't offer condensers for your application. Also Sierra reboxes other parts, they generally don't make anything.

Sierra is junk. They rebox the cheapest parts they can find.

You know in all my years of working on boats, I never considered this "reboxing" of parts scam? Those aftermarket guys must be shady characters to do that stuff. How prevalent do we think that is?

Finally solved the problem!!! there's an insulating tube between distributor housing and the bolt that holds the points and provides power--had a hole in it shorting to the distributor housing!! Knocked the metal out of a 10-12 ga StaKon butt connector, cut to fit, took a 4 hour ride last Sunday!!! Thanks for all the come-backs, guys!!

GREAT fix!
That would be a hard one to find.
