    Formula 27PC Complete Power plant rebuild

    Talked to Eddie Young today at length and he advised that (paraphrasing) if I had a go fast then I should go for the Holley EFI. Since I need torque more then HP he recommends I need to keep the intake I have and have it worked. The intale I currently have will produce a lot more torque then the...

    Formula 27PC Complete Power plant rebuild

    We pulled the engine and started disassembly. Everything is looking good but do have a couple shinny spots on a couple pistons, maybe a bit of water go in. Took some pics but they didn't come out. Will take some more and post later.

    bilge problem

    You have a break in the connection somewhere, either the switch or wiring. My first place to check is the switch. The switch should have 12V going to it. The power will either go direct to the switch or direct to the float switch and then to the switch at the helm. When the switch is in the...

    06 Volvo Penta oil alarm problem

    Unable to see your pic clearly and also don't know the exact 3.0 you have but I'll put it this way. There are two senders attached by a tee fitting coming from the rear of the engine at the oil pressure port. One is large (item 13) and that one would be the sender for the gauge. The other is...

    More power to heavy cruiser, is it worth it

    Not really, I currently have to lay across the intake upside down just to change the impeller. Good thing I have the MPI intake or this would be a bit harder, If I go with the Holley EFI setup the intake would be lower but then there is the throttle body which resembles a carb. Original MPI...

    HELP Mercury 5.7 willnot idle

    Need to try that rebuild again. Your carb at no time should be dumping or pouring gas into the engine. This is way you can only keep it running if you rev it up. Either your float is sinking, float level is set incorrectly, needle valve is not seating and shutting off the fuel into the bowl when...

    Temp. gauge issue on KAD 300

    It could be the sensor, cannot say for sure. Item 29 is the sensor but does not show where it goes. I will say every temp sensor I have seen is in the thermostat housing

    Merc 4.3 I/O thunderbolt V issue please help!

    :welcome: to iboats Smitty An engine serial number would help, but I'm going to go with this is a carb engine. To find an electrical problem you need to at least have a 12V test light, and volt meter would be better. Throwing parts at a problem is one way to lighten your wallet. It sounds...

    Bravo Gimbal ring wear

    The top of the B3 outdrive only sits about an inch above the water line so the top pin seal is always under water (single engine Formula 27PC). Several years ago I replaced the top pin and seal due to corrosion and water leaking in. Sent the gimbal ring to a company who also made the pin. When...

    Just FYI - replaced impeller should have paid more attention to belt

    A previous thread I posted mentioned about replacing my impeller last season. This season I noticed the temp was going a bit higher then I was use to so I pulled the impeller to have a look. Turned out it had crackes and needed replacing. I bought several impellers years ago and achris noted...
