Anybody running this non marine carb on a 351? The 1409 is the marine carb. Any issues with the 1406? I know, Holley Holley Holley, but this is on the boat and like new!

Don't do it, Non-marine carb is a time bomb in a boat..

I'm not sure why but I know of a few people back home that burned up their boats with non marine carbs.

Wow, didn't know that! I got the boat for $5900 so there's $$ room for a new carb.

Reading here tells me to go with the Holley 4160 for $499. Agreed?

I never put anything on my engine that is not marine, it is not worth risk v. money savings.

Ever had a float stick open on a carb? The carb has an overflow tube to deal with that situation; in a car it dumps gas all over the ground. This is a Really Bad Idea in a boat, because it dumps gas into the closed engine compartment. Any spark, and you'll be wishing you'd spent the $500 on a marine carb.

On boat carbs, the overflows are plumbed to dump into the intake manifold instead. A terrible idea, as a sticking float will make the boat run like crap, and may prevent it from running at all. These symptoms are a whole lot more attractive when you consider the alternative is blowing the top half of the boat off the bottom half, and engulfing all the passengers in a cloud of burning fuel vapor.

In other words, get it off the boat now. Sell it on Ebay, and use the proceeds towards a real marine carb. Check the Alternator and Starter while you're at it - if the owner replaces the carb with a non-marine version, he might have done the same with these. They both need to be marine versions.

You should also check the fuel pump. The fuel pump has a diaphram in it and when it fails in an auto fuel pump it dumps fuel on the ground and the marine fuel pump is equipped with a clear plastic tube that runs from the bottom of the fuel pump back up to the carb to dump in it.

Agreed. 4160 was the original carb on that boat and works really well for the application.

you can find them cheaper
u must have a solid line from fuel pump to carb
braided lines are not USCG approved

Not gonna mess around with this one! Just ordered 4160 carb, and fuel pump with line from SkiDim. Thanks to all for the replies! Looks like I've got a fun weekend project coming up, never swapped a carb before!
