Buy some throttle body cleaner/de-carb! Using fuel in spray bottle not to safe! One backfire and it could be a burn issue!

If that dirty, then put screen back in, reconnect that line. But before running it again (find the hose off the top of fuel rail(s), and disconnect that line (rubber hose) that goes back to the vst (disconnect it at the vst). Put that line into a jar/ container, and turn the key on to the first position. The HP fuel pump should push the old fuel out of the fuel rail into the container. Only turn the key on for 3-5 seconds. If fuel doesn't come out clean yet, do another 3-5 seconds. This should clear the bad fuel out of the rail. Reconnect the hose back. Then fire it up on muffs, if not running better, try the squirt bottle like I said.

Once you clean that hp filter screen, it should be fine, unless it is torn. If not torn reinstall it.

Let us know how it works. good luck.

I drained the fuel rail like you told me to do, the fuel that came out was really dirty and black, had to cycle the key on like 5 times until i got clean fuel coming out. I fired her up on muffs and it is running a lot better now. Did try the squirt bottle and the engine sped up every time I sprayed into the throttle body.

Ok. Yes fuel was bad. Are you still running on portable tank, and did you add a good cleaner additive to fuel? Something that will clean injectors, and fuel system?

Can you try the boat in the water now? It may run poorly at first. I am hopeful that flushing through the fuel system, then adding the cleaner, you may be able to get the motor to open up and clear out any remaining old fuel. But run it in the water near as possible to landing just in case of problems. Then let us know how its running.

I am still concerned if injectors will need to be cleaned?

Post us back when possible. Good luck.

Yes still running on portable tank with some sea foam as well. Put it in the water this morning but still bogging down when you give it throttle, I stayed as close to the dock as possible but still ran like crap, barely got over 1500rpms without shutting off. Should I go ahead and pull the injectors to get them cleaned?

[Solarman]

No not yet. Do you have a service manual?

The next thing to check would be the stator. You originally had a burned out rectifier, and i'm wondering if that was part of the damage caused by the stator?

So the check of your stator needs to be checked according to the service manual for your year and motor.

Post back when able. Everything you've done this far is good. But check stator before spending money on other areas for now. Good luck.

Viking funeral bro!😝

[Bamahemi]

But really,keep on trucking you'll find it!

[stratos20]

Pulled the fuel rail and injectors and will bench test them tomorrow to see if they are all working, 2 of them did have the o-rings almost gone. I also noticed the hose that comes from the top low pressure pump into a T was bone dry, had to pull it off to get the fuel rail out, no fuel came out of the LP pump either is this normal? I haven't had a chance to test the stator output yet I was told I needed a dva to do so or could it be tested with just a regular digital voltmeter? Suzuki manual sucks by the way.

[stratos20]

Got a video of it idling, she starts right up, what do you guys think is it miss firing or does it sound decent?

Can't view! Says its private

[Solarman]

Can't tell. Video listed as private.
How does it run?

[stratos20]

Try it again just made it public. I think its running a whole lot better, found out the plugs were the wrong ones with the wrong gap so I re-gapped them, I flushed the injectors myself at home and lots of crap came out of them like pieces of rubber so they were defenetly clogged. Will test on water sometime this week and report back.

Sounds like half of it is running, I would seriously look for another used late model motor if you could! Are you planning coastal or offshore for this boat? If offshore then upgrade! I know that's not what you want to hear butttt your life and safety is worth it!

Bam, how bout back off. You have only added negative comments since you started, so ”kindly take a hike”, and let some of us try and help him.

Stratos, if wrong plugs, did you change them? Re-gapping wrong plugs may not help much?

Also, if getting lots of black matter in fuel, then you may have fuel lines breaking down internally, and need to replace them (replace with ethanol resistant lines). This is normally caused by the ethanol fuel. Unless you replace those fuel lines, they will continue to deteriorate and block screens and injectors.

If you have no fuel from low pressure pump(s), then this too should be looked at. You may have cracked, or damaged check valves (clear discs in base of pump body), or the diaphragms may be bad? New check valves ONLY come with new pumps.

Check these things, and post back what you find out. Good luck.

I did replace a few hoses in the motor that were in bad shape, the other ones seemed ok. I ordered the correct plugs they should be here today or tomorrow and will swap them out. Is there a way to test the LP pumps to see if they are working?
