Has anyone had problems with ProcCharger Systems on their MerCruiser engines besides me? Blown head gaskets , fuel system headaches, and other gremlins. If so I would greatly appreciate you listing them

Not personally,, but heard alot,,, I was told NEVER run a Procharger without changing head gastket to the metal ring style,,, also heard of #8 cyl lean problems, and a bigger injector has been used in only that cyl,,,, HMMMM !!!!

I ran 5 lbs of boost with m1sc systems for about 120 hours. Totally stock stuff. Never a problem.

I ran 5 lbs of boost with m1sc systems for about 120 hours,,,,,,,,,,,,,,,,,,,,,,,Then what happened,,,,, thats one season of boating for us.????

I run a stage 2 ProCharger at 5-6 lbs with stock head gaskets,no problems at all!Also know of six other people in my area with ProChargers,no problems! I have heard stories of people running ProCharger and Whipple that have had those type of problems though, I am sure that if either system is properly set up and only premium gas is used that all are trouble free for the most part.

Who set your system up? Tell us about what you have & problems.

Have friend who had procharger on his crownline. He ran that thing wide open all the time. I was waiting for motor to let loose but never did.

Friend has 2 on his new boat & after about 200 hrs still going strong.

I have stage4 setup that I put on first of this year but only have about 25-30 hrs so far with no problems.

I'm on my second Procharger boat now (twins) & I have never had any problems with or as a result of the Procharger system.
Ran 5-7# boost on the last one, 5# on this one with EFI- Arizona speed. All had/have original factory gaskets.

You need more fuel. I ran a seperate line to the rails for more flow and also made a real return line from the regulator to the tank. I tee'd into the breather tube for the gas tank and my regulator works awesome under boost. Are you running stage I or II? More info in general would help. Replace the factory head gaskets with Felpro's also. Keep in touch.

Setup was done in Long Island, ECU was sent out along with Manifold to be modified by Arizona Speed , head gaskets were changed as well, still blew head gasket on port engine for the 4 time with less then 8 hrs.

What is your fuel pressure under boost and did you tell Jim from ASM of this problem? Hate to say it but a few people seem to be unhappy with their new computer tune from ASM. If you are running stock injectors then you should have a good 60psi to help feed that boost. Alot of ProCharged users are still running the factory computer with no changes in timing, fuel ect. Is it always the same piston area for the blown gasket? This should not be happening. Are you bouncing off the rev limiter during a run and do you seem to lose gaskets at full speed or at any RPM? Sorry for all the questions but your situation seems to be rare. 4 times in 8hrs is just incredible to me. If it would help you then give me a call so I can hear what you have going. I will PV my cell to you if you are interested. Scott
