For some reason this thread will not let me "like" your post but Thank You. The shot does have a cool look to it

as of today FST filters do not install to the OEM Merc mount --- Black production side nor any Volvo s. Also will not install to some of the Merc racing engines either.

If room allows the biggest filter the better but quality depending.

Racor is a good filter but not cheap priced either.

Reload or refresh the page. Then you can do it.

Faster than OSO Tech huh ? LOL.

Straight out of the shipping box --- 496 injectors always need to be check out and service. NO BS these more times than not really need to be deep cleaned --- https://cimg1.ibsrv.net/gimg/www.off...77b067908f.jpg

tested and flow tested - --- so very common as they suffer from many contaminates - he is one of them. Straight out of the box - 2008 app not that many hours

would you say the contamination in that injector would be from the ethanol content in the fuel, and fuel /water contamination to turn it that yellow/brownish color?

if there was no water contamination i would suspect thet the ethanol would just leave white deposits correct ?

That set of 8 had rust thru out the cool fuel and alot of rust internally in the fuel rail. Water intrusion and it sat around for X AMOUNT of time. That was not from E 10 because the other engine was not like this period nor experienced the loss of 300 rpms. .

to further expand -- alot in the issues at hand cause injectors to end up contaminated internally all way thru the injector itself. .

Lack of maintenance

Lack of fuel maintenance

improper lay up for seasonal storage and or winterization.

water in the fuel and E 10 is NOT the main source of water intrusion

poor quality - some of these marine parts. ie: fuel rails , cool fuels, seals on top of the gas tanks, gas caps themselves, fuel lines, fuel pumps, fuel filters and so on.

496 injectors suffer from contamination -- so hard for them NOT to. I prob have 1000s of pics -- 496 injectors and most are in need of deep cleaning and flow testing beforehand.. Marine injectors suffer by far worse than ANY auto side injectors. BY FAR. - freaking junk yard auto injectors can be in better shape than alot of marine injectors sitting in owners garages.

BUP can you test this type of injector? I dont believe they have a screen or do they?https://cimg8.ibsrv.net/gimg/www.off...90b52505e2.jpg

tried to send you a pm,

YES I can. Any gas side injector I can test EXCEPT the Etec injectors. They require 50 Volts to do so and at steady state. But soon I will be able to test all Etec injectors. For those whom do not know etec that is Johnson and Evenrude outboards systems / engine and injectors.

I can TEST and clean all marine MPI and GDI and DI injectors for outboards, auto, truck, natural gas, jet ski, marine I/O and inboard. Even Merc Opti max - and Yamaha HPDI.

Also the 8.2 Mercruiser Cat engine and that requires special attention. Those injectors a person can really jack them up. And those are not cheap to buy period.

I do have alot to say about your injectors. for starters they become restricted flow in patterns and flow volumes.

VoodooRob as he has basically the same injectors. He knows what I had to do to make all that flow very very well again.

I will post more info about them. THANKS for asking as well.

Here is some of the jist but there is more as to why these really need to be tested and CLEANED. NO BS. I have to find some of the parts here to post what Im talking about.
