Nasty Nasty Injectors

[HDETERS]

Just got off the phone with Don. I had sent him my whole injection setup (worth the couple of extra bucks just to send the whole thing) to have the injectors cleaned and flowed. I have to start out by stating I didnt feel I had any issue at all with the system. It is 16 years old and I just figured it needed to be done while the boat is down for the winter. Well, from what Don has told me, my injectors were in need of attention. I will be posting pictures of the filters when Don sends them back. I am posting this so for those of you who have older engines and have never had this done, get it done. I am sure I wasnt far from blowing the engine apart from poor fuel delivery. This is cheap insurance and it is easy to remove and send off. GET IT DONE! It will be March or so before I fire up the engine, but I am sure there will be a big difference in the way it runs verses last fall.

All the black you see on this coffee filter came out of the INJECTORS.

As received, these injectors had a variance ranging from 12.87% at idle... to 8.57% at WOT. For these injectors... we prefer to see no variance in excess of 2%.

FOUR injectors were found to be flooding.

After cleaning, and recalibration of FOUR injectors... all are again happy, and well within tolerance. </td></tr></table>



Thanks Don

Did you run fuel additives?
I run quick clean, sea foam and another mercury product for ethenol (forgot the name off hand) every single time i get gas. It's very exspensive, but IMO, it's less then a rebuilt engine due to the crappy gas nowadays.

Glad you caught this before having a ruined engine.

I run everything Don tells us to run. I have only owned this boat since 2008, so I dont know what the first owner did. I doubt many of the owners of older boats are the original owners, so they face what I have faced.

My point here is, I did not feel I had any problem with anything. I just decided it was time. Glad I did. Dont wait till its too late.

Hans.... those were DEFINITELY "nasty". Probably the worst set I've seen come off a "running" engine!

I've bagged up the old filters for you.... though they really don't do justice showing just how bad these were. VERY glad you got them in... they're squeaky clean now, and flowing MUCH better.

An occassional good run won't hurt things, either.

Thanks Don.

Hans,this would be an opportune time to replace those risky metal reeds,before you reinstall your intake.Im confident you would notice the improvement in running,and you won't have to worry about damage from a broken reed,call me if I can help,Chris

I REALLY need to get off my azz and do this with my Opti on the Fountain. Hopefully the new redesigned compressors will last long enough to allow me to get to some other things like this!!!!!

Pictures added. I will work on getting a more focused photo of the old injector filters. Don may add how my injector test turned out. Thanks again Don!!
