I owned an '85 S&S for 24 years and never even upgraded to electronic ignition. In that period, I think I had the carb rebuilt twice. Sure, it could be a little finicky at start, especially if the weather was cool or damp. I just let it run for a bit on the trailer while launching, or started it before untying dock lines. Never a big enough hassle to justify spending over $1500, and probably making the engine much harder to diagnose.

I do think it is very important to find a good mechanic, and especially one that will lake test the boat.

It seems like a minute or two. It usually cuts off once or twice at first and then I get it set at about 1200 rpms and warm it up. Then it runs fine. Oh, I did install a new electric choke as the old one was not working and it did not seem to make any difference.

I would look for a problem that is worse at cold start like a vacuum leak at the base of the carb. Could be your idle mixture is on the lean side. How long since your carb has been rebuilt?

How do you know I have a leak?

Don't know for sure. If an engine is stalling during warm-up, it is usually because of a lean condition. As the engine and carb warm up from operation, the metal expands and seals small gaps caused by dry gaskets that shrink over time and leak when the engine is cold.

Air entering through a base gasket leak will lean out the mixture. The carb can't add more fuel because the leak is below the carb and may cause stalling until the engine warms up.

It doesn't say that it is marine approved. It may be, but the cost is prohibitive.
