well i looked at the manifold diagram in my manual, i see the hose your talking about on the diagram, but i for some reason do not have that hose on my engine. they must have changed something.

Replacing the carb float should drastically reduce the amount of fuel that gets dumped into the crankcase and then overboard. After 50 years, the carb float (originally plastic) is fuel-soaked and does not do its job properly.

Watch out for bad seals on the lower end. I need to tear apart my lower end due to massive leaks (leading to that water sheen they're talking about) and replace those. Good luck to all of us finding parts for these monsters!

This thread is over 10 months old.

And somebody searching the forum for useful info on this engine might still appreciate the help. I found it when it was six months old, and it helped a great deal.

The carb float on that motor was lacquered cork, with a brass clip that held the pivot rod.

these motors are known for eating up the clutch dogs in the lower unit but you should no this a powerful motor that in my opinion would put any new 50 hp to shame i wish i was so lucky to have one of my own!!!!

I just found it TODAY and I find it very useful since I just bought a '58 "fat fifty"!

The knowledge here is very much appreciated.

I know this is an old thread but for those who come across this information I wanted to add that on my 1960 75HP starflite II motor there is a crank case drain (raw fuel/oil) line that is located at the bottom left of the block that runs around the left side of the engine (if your facing carburetor) to the exhaust where the raw fuel is dumped. You can intercept that wasted fuel mix and send it to a catch can or back to the fuel tank to improve fuel economy.

In this EPA report from the early 70s several outboards were tested and the old V4 motors waste about 30% of there fuel at idle by draining it straight out of the exhaust! https://nepis.epa.gov/Exe/ZyPDF.cgi/9101RUE1.PDF?Dockey=9101RUE1.PDF
