Here's the vid guys, could my problems possibly be a cracked block or something? 120 psi on both cylinders

BTW, this engine has a new water pump and t stat. The water coming out of the engine isn't hot.

Let me know if this is normal or not... I could have swore I remembered less water last summer

HI DougyB. That looks great to me. It's pumping lots of water out of both the exhaust ports and the tell tale (pee stream), which is exactly what you want. Idles nice and smooth too. I think you're good to go. Happy Voorm-vrooming!

KFA, unfortunately the video doesnt show the bad. Once in a while when in water, she will cough at idle and die. The engine runs good cold but after a bit starts to sputter, and as today showed, after a whileof putting around inconsistently, doesnt start at all.

You don't tell us what motor it is, but have you at least tried decarbing it? At the worst, if it's old enough might be time to rebuild the carbs.

Did you put the spring back in on top of t-stat??? .....looks like t-stat is hung open as it works as a poppet valve also.

Re: Loosing patience!! lots of water from exhaust ports

Often times when a motor stops working after running for a while there is an electrical issue. As the components heat up they fail. After the they cool, the motor can then be restarted. On older motors with simple, magneto ignitions it's not as much of a problem, but on motors with electronic ignitions it's more of an issue. I don't know much about newer motors, but perhaps someone else will have some tips on diagnosing your system.

Re: Loosing patience!! lots of water from exhaust ports

KFA, unfortunately for me I dont know how to do much other than swap a powerpack and coils, which I have already done. I did have one bad coil. The motors a j25tecdc with a clean carb. I did put the spring back in the t-stat, but lets just say it didn't seat properly...would that effect how my engine starts to sputter?

I plan on going out tonight on the local lake and running it till it will not even start back up. I then will do a gap test and see if its not shooting a spark.. Other than that, I have no clue what to do. I have heard to check the trigger and stator wires for resistance, but am not sure where to find them

This may sound rhetorical but I wonder of your tank vent is plugged if it's open. Just watched your lake test video and sounds sort of like it's just running out of gas. My question from the video, was the bulb actually flat or just depressurized? A plugged vent can cause a sound running motor to just quit, then priming the bulb again it will run fine for a about a minute or a couple minutes.

Looks like you have the water turned on full force with the muffs which is overiding the impeller; two of my manuals say to use half-force or lower so you don't get water in places you may not want water.

Ok so you know that the T-stat didn't seat properly and you are asking if it could be a problem, they seat them properly from the factory for a reason!!

Sixmark,

Sounds more like he is saying just for the sake of argument that it did not "seat properly" and in that event could that be causing the problem?

It's very simple taking out and reinstalling a thermostat. it's pretty straight forward. It's not like you can put the thing in upside-down
It's not like seating a jet in a carb. Just make sure it is back in place the exact way you took it out and you should be fine.

It's not likely that a significant amount of water is getting around your t-stat.
Just open it back up and check it. You should be able to see if it is in askew.

All that being said, I don't think that your t-stat is your problem anyway.

Will Bark's suggestion may be correct.
Check it in a test-tank/large garbage can. If you can't then test it in the water with someone observing the exhaust.

I'm not convinced that the large amount of water in the exhaust is related to the motors poor performance when hot anyway.

Let us know how your water flow problem is after you lake test it.

Re: Loosing patience!! lots of water from exhaust ports

Water flow stayed the same in the lake, upon experimenting tonight I have found that even though the ball stays kind of hard all the time, if I continuously pump the ball the problem doesn't occur and the engine will run till my forearms feel like popeye.

The reason I did not think it was a fuel problem stemmed from an air leak test I did earlier. When the engine stalled after a nice long run with almost no air bubbles (literally one bubble at one instance) found in the line, I figured it crossed off that problem. I replaced the fuel pump, and the problem persisted, making me think its definately something else. Obviously I don't know how to perform an air leak test, or simply don't know what to look for, because the carb is not getting the fuel at an easy, steady flow. Today on the water, when the engine would not start, the primer bulb felt like it had sufficient gas in it, but I'm guessing my carb was just simply empty of fuel.

Dating back to this winter, I tried to install both an inline fuel filter and a water/fuel seperator. I found the inline was too much for the fuel pump, so I spliced the fuel lines together to connect where I removed the inline filter. While this is sealed very tightly with the proper fuel line ties, my thinking is that in this splice either a current or disruption in fuel flow is introduced into this equation that just gives the fuel pump a hard time. I also think I can shorten the line running from the fuel pump to the carb, as there is a good 3-4 inches of slack line.

Re: Loosing patience!! lots of water from exhaust ports

sounds like a fuel pump problem have you checked the flow from the pump or the filter screen?

Re: Loosing patience!! lots of water from exhaust ports

There is one way to check if there is enough fuel volume being drawn to the fuel pump. It requires you to put a TEE connection right before the fuel pump inlet and attaching a vacuum tester. You would need to have the hood off and run it on the lake again. Try having someone drive the boat while you watch the vacuum gauge. I don't have my book in front of me but I believe it should be pulling between 2 and 7 pounds of vacuum at idle. Just watch where it is at idle and see the increase as it runs up the RPMs.
It shouldn't get much higher then 18lbs. @WOT I believe. Some one else may be able to give you the exact numbers to look for, but the point is to see where the gauge is at when the motor starts acting up. If there is a restriction in the system it should raise the vacuum pressure dramatically. If it does jump up, then you know the fuel system is the culprit and it maybe that water/fuel separator or plugged gas vent. Hope this helps out.

Re: Loosing patience!! lots of water from exhaust ports

Thanks for the help guys. The fuel lines are all new on this outboard, along with the outboard and even the gas can. I'll look everything through just to be safe. If removing the splice does not work, I will have to do a vacuum test and see if my OEM fuel pump just isn't doing its job.

Re: Loosing patience!! lots of water from exhaust ports

Try taking the fuel pump apart and examining it.
They are not complicated, and you should be able to see if there are ant holes in your diaphragm (hold it up to the light, feel it flip, it over)

Put it back together just how you found it (unless something it wrong).
While you've got it apart try washing it with dish soap and water.

Re: Loosing patience!! lots of water from exhaust ports

got it fixed guys, ended up taking carb off and re-ziptieing everything, fixed the air leak
