Lot's of idea's. Worn plugs, carboned up, dirty carbs, needs sync and link, carbs need adjustment, improper timing.
What is it doing? What rpm does it idle at before it dies? Mine is idling around 600 in gear.

when it first starts up it does not stall at idle. After running wot for a few minutes, I pull back to a trolling speed at around 700-800 rpm then you see the tach drop and then die. Other than that it runs great.
Yeah I had a similiar problem. Gt150 ran grat when it first started but when I wanted to idle back in or load onto trailer it kept dying. I replaced the fuel filter and also added a canister one from basspro and it idles like new. Broke the small, old filter open and it had a couple small pieces of leaves in it. looked pretty clean but you could barely blow through it. Barely visible deposits in the mess. Cheap fix which took me a short time. I also replaced the internal hoses and clamps. All I had to do is touch one of the plastic clamps and they broke. May have occasionally sucked a little air but not sure. I think the filter was original.
I just put a new filter on it with new hoses. The motor has 12 hours on it. I rebuilt it myself. I have built a dozen engines over the past 10 years. This one was the toughest being a six cylinder and optical sensor. I bought that tool to time it.
My 225 did the same thing..Cleaned the carbs and set the timing...Runs great now.

I would do a sync and link on the carbs, and check the mixture. You must have the motor in the water or it won't work right, trust me.
I put mine in the water strapped down on the trailer and ran it in gear to check the idle timing and set the mixture. It idles fine at 600 in gear.
I would also check and make sure you aren't leaking fuel around the fuel filter. I have had that give me some issues, because if it leaks it sucks air and you have problems with aerated fuel.
You could also have a vaccum leak, especially considering you just rebuilt it. I know when I put these bigger carbs on my engine, I didn't find the pro-marine gaskets that go between the intake and the throttle bodies to fit properly, so I reused my old ones and ordered new ones from BRP.

Please post your modle and serial #'s for the guys. Some of the eagles had fixes for something as simple as dying while trying to load on the trailer. More info gets better answers.
The model # is E150GLEOM
Seeing he's done a rebuild on the motor. I'd check head temps and idle timing. You can't set the idle timing on the muffs you can get close but you need back pressure to set. You need to make sure the T-stats are opening correctly. Also make sure the throttle roller is in contact with the timing lever.
Does he need it in the water with the OMC timing tool?

The tool is used when the engine is off.
What are your RPM's at idle and in neutral in the H20? And in gear?
When it is cold and first started up the rpms are 1000,1100. After running for a few minutes I will pull back to troll and the rpms are 800-700 and in a few seconds they start to drop 600,500 and stall. Sometimes I have to push the key in (choke) to get it going. All carbs are spotless and idle mixture is 3 turns out like the factory book specifies.
Where are the timing notches on your arm?
Back the mixture screws out some more. If you have to shoot fuel at it with the primer to keep it running, then it needs a little more fuel. IMHO.
Also the number in the book is a starting place. Mine says 5 turns for a 96, but I am closer to 6 turns out.
Put it in the water, strapped down to the trailer, warm it up, and then play with the mixture and see what happens. Mine was at 4.5 turns out when I set it on the hose, and that was to lean. It should spit a little if lean, and then smooth out as you get the mixture right.

I do not understand the question. What do you mean by arm?
Perhaps where you set the idle and wot throttle timing? Are they in the middle, or towards one end or the other? You know those little ratcheting things.
Mine are both in the middle.
I still think your mixture is off. My manual says you "may" have to richen the mixture up if you run a high pitch prop. If you have a 19 foot deep V, that would probably be about the same as a bassboat with a high pitch prop.

My prop is a 15x 17 which is a standard size. The diagnostic tool that you set the timing with has a red light and those notches are moved one at a time until the light goes off. Thats how I set it up. It is funny because I now have 12 hours on the engine and when I first built it the motor would rev to 5100. Now it is revving to 5600 rpm. Some people said your tach is off or the throttle plates are not fully opened. I have not touched the tach or throttle plates. I just think it is breaking in and once I get this idle issue fixed it will be a sweet engine.
Three turns out is a starting point. You may and often do have to adjust from there. Make sure your in the water while doing this.
