    Don't think it's the coil, I'm still thinking a connection, maybe even the key switch

    Don't know which motor but As Ship mentioned, could have a local shop rebuild one if it's something like a 5.7 motor. Get one from a truck at a junk yard and rebuild, or if you find a good running one, just change out the core plugs and head gasket, then use all the stuff off your motor

    2006 Monterey Boat with a 4.3L Mercruiser TKS Engine S/N 0w354897 Mysterious Loss of Power

    The fumes out the carb is just liquid fuel in the intake Something must be getting hot and there is a bad connection stopping the fuel or spark. Starting fluid worked before but not next time. Use to idle but then wont' Agree, need to check power

    7.4 /454 Gen VI identification

    High octane burns slower then low. Running a motor with high when built for low just reduces the amount of available HP With marine motors reversion is key. Need to know the lobe separation and amount of overlap to determine how much protection is needeed

    Welcome Don't hear their name come up much and have not heard anything bad. Many here get them from Michigan Mortorz and keep in mind most want a rebuildable core or it's going to cost more

    7.4 /454 Gen VI identification

    Thanks Someone built a 454 mag (block, 502 heads, 525 intake), but may also have pushed power above 385HP. Figure out what the cam specs are to determine if reversion is a possibility

    4.3 Wet to Dry-Joint Conversion.

    Old style man restrictor gasket help keep mans full of water. By restricting some of the flow, this allows both sides to be full and closer to even. If no restriction is used then one side is always a bit warmer then the other. Could get into it further but you need manual 37 when using dry...

    Planning out installing NMEA 2k

    While it doesn't matter which direction the multi port or Tee fitting is connected, it does matter that they are all connected in same direction. Don't start it 2 spots and connect in the middle without really paying attention

    7.4 /454 Gen VI identification

    Welcome The intake most likely came off a Merc 525. Look for the block casting number on the rear deck of the block just below the distributor The motor has 502 heads, look around the rockers for a casting number and last 3 digits might be 088

    Rusty u joints bravo 3

    Replacing bellows on a Bravo is pretty much the same as the Alpha With a B3 I would use an exhaust tube instead of the exhaust boot. It's easier to put on but also will be a bit louder when running. The B3 doesn't have much of an opening for exhaust due to twin props. Need to remove the...
