    2013 - 2016 V8 Mustang vs Camaro? Same prices, I love them both

    A lot if not most of the Problems is because they are using Control Modules to operate things that used to be hooked to Switches and Knobs. A real PIA to Troubleshoot, and most Techs now just keep changing Parts, and charging for them, until the Problem is fixed, which it may never be... In...

    2013 - 2016 V8 Mustang vs Camaro? Same prices, I love them both

    In 2004 when the Revived Mustang was introduced, I wanted one. Several times I had made a deal at the Stealerships, including one where my Cousin was the Fleet Sales Manager. But I could NEVER bring myself to finalize the Deal(s), simply because it was a Ford. I was Never a Camaro Fan(too small...

    Mixing oil?

    They will mix fine, and the chances of damaging the Engine are Nil as you will just end up with an Oil that is tiny bit more Viscous than 10w-30

    Mercury 135 not running

    Welcome to iboats If all the Pistons are moving, then I doubt a Rod is broken. One or More may be bent, which can cause Binding. I suspect you are going to have to split the Crankcase and take a look inside Pull the Heads off first, and see if something is stopping a Piston

    85hp charger speed/prop/rpm concerns

    Now 650 on the Muffs is gonna be about 500, even less in gear, when in the Lake. However if it was reading 1040 in Neutral, was that on the Muffs or in the Water? If these revised Rpm Numbers, due to resetting of the Tach, didn't require any adjustment to the Idle Stop, then I suspect you...

    You aren't familiar with the 1960s OMC V4s. 3 mpg would be Exceptional, a Stop the Presses Achievement.

    85hp charger speed/prop/rpm concerns

    I doubt that Engine would hold together for long at 7000 rpm, so I suspect the Tach is way off. Idle speed in gear should be around 600 - 650 rpm. If you have 1000+ in gear Idle, the gearcase will be taking a Beating when shifting

    Engine tune-up spray

    No it is Not the Same as SeaFoam, as it actually does soften Carbon, so as to free up sticky Rings. SeaFoam, being mostly a very light Oil, simply makes a lot of Smoke Merc's Power Tune is also Superior to SeaFoam, CRC makes a couple of Good Combustion Chamber Cleaners too. Granted todays...
