I bought a 2004 190cc Seaboss with a 2004 Evinrude 150 2 stroke. The previous owner said he has not taken the boat out this year, the tank was half full and I asked if he had put any fuel stabilizer in and he said yes. I took the boat to the gas station and filled up with non ethanol gas. Went out on the lake but was cut short due to weather. Engine ran fine just never got a chance to go above 3000 rpm. Went out yesterday to fish and engine started fine but after 2ish minutes at 3500 rpm, engine started to sputter and over the next 30 seconds bogged down and died. I checked the primer bulb and it was still firm, after several attempts to start the engine fired back up. After idling for a minute or two and checking over everything I took back off but only made it 30 seconds and the same thing happened. It took a lot longer to get the motor started but I did and put the engine in gear around 900 rpm and trolled back to the dock. Changed the fuel filter and took the boat back out that afternoon and it ran fine up and down the river at all rpms for close to an hour. Today I went out again and the exact same scenario as yesterday happened even died at the exact same spot in the river. I can fire up the motor no problem and will idle all day with only minor sputter here and there. I have drained off several gallons out of the tank and no signs of water or any type of sediment. A friend suggested I drain the fuel tank but it has almost 40 gallons in it. Hoping someone will having another option.

When you say "changed the fuel filter" do you mean a fuel / water separator filter or the fuel filter on the engine (under the cowling)? It sounds like a fuel issue.

Is this a VRO engine? Theres an inline fuel filter just to the left of the vro pump. First thing I'd do is clean that filter and run out of a portable tank or gas can with new fuel in it. If it runs great, then it's likely the fuel in your tank, if it doesn't, its time to start looking at the engine.
Oh, and if you haven't replaced that primer bulb, do it. They are cheap and they can cause all kinds of problems when they age.

It was a fuel/water seperator under the front lower cowling, it is a VRO engine, what would the inline fuel filter look like? I am going to purchase a new primer bulb and use my buddies external gas tank with new gas. Engine model #F150FPXSRS

follow the fuel line from the vro pump, look to the left of the pump it looks like a screw on plastic cap with a 90 degree nipple on it. Unscrew the cap and the filter (more of a screen really) is under it. Just rinse out any debris with a cupful of gas and put it back in.

Changed the primer bulb, I could not find the inline (screen) filter. Went out today same thing as before, I then had my son start pumping the primer bulb and I did not have any problems as long as he pumped every so often. Thanks again for all the help, does this mean a fuel pump? Is there sometime type of ops ck I can due to test the pump?

Yeah, that's a good sign of a fuel delivery issue, likely the pump. I've sent you a pm.

Yep as freezer said sounds like the pump, just had the same thing happen on my Yamaha.

As already stated, your problem is more than likely the fuel pump. It could also be the fuel check valve, but the majority of the time it's a worn or punctured fuel pump diaphragm. The diaphragm is replaceable, so don't go out and spend a bunch of money on a new fuel pump when all it needs is a new diaphragm.
Even before you do that, have you pumped the primer ball tight and checked for fuel leaks? Something as simple as a leaking fuel line can cause the same problem.

Something as simple as a leaking fuel line can cause the same problem. Very good point, it is much easier to draw air through a line leak than fuel. The only thing that doesn't make sense is why your fuel bulb would still be tight when the problem occurs. In either case of a bad pump or a line leak, the bulb should have to be pumped at least a few times to get fuel back into the carbs. (unless I misread something). Anyway, I'm going to send you something when I get back home tonight that should help you. Oh, and welcome to the forum! |

Sorry for the delay work has been horrible. I cannot find any air leaks, I'm to the point of changing the diaphragm for the lift pump but cannot find a rebuild kit as Juan stated the part # for the pump is 5004460.

Ahh. Ignore everything I've said. I didn't realize you were fuel injected. Yeah, looks like they don't make a rebuild kit for that pump.
