    1999 270 DA NMMA plate - anyone got a pic?

    I have a 1999 270 Da and the NMMA plate is worn off. Does anyone have a picture of what the plate actually says? Its a single engine gas boat.

    Who has replaced the Kiss cooktop with something other than a cooktop?

    I have a Kiss butane cooktop and the wife is scared to death of it. So I am going to remove it (and sell later) but would like to put maybe a sunken tray with a butcher block where the cooktop was. Has anyone done something like this? Looking for pics and ideas. Thanks

    1999 7.4 fuel rail leak

    I can't seem to post a pic of it as it say file too large and I don't know how to make it smaller. But its a hair line split just after the bracket where the fuel line comes in

    1999 7.4 fuel rail leak

    I have a 1999 270 with a 7.4 mpi. I replaced the fuel pump and upon trying to start it I smelled gas. I have discovered at the back of the fuel rail right near where the fuel line connects there is a hairline spilt in the fuel rail itself. I'm not sure if it can be fixed (brazed closed) but...

    1999 7.4 won't start

    Okay got the fuel pressure gauge on it. Turn on key, pump runs for a couple seconds. Guage reads 20 psi. Tried to start engine -same reading. Took guage off, release residual pressure from fuel rail. Started all over again with pressure guage -same result. So it needs a new fuel pump. Anyone...

    1999 7.4 won't start

    If only it had a carb. My 71 SS has the 454 with a carb and I can rebuild that one blindfolded. This is MPI and a little harder to diagnose but I am still leaning towards the fuel injectors being all crudded up as the ethical gas does quite a number on them and people are inherently cheap when...

    It has good compression. I have ordered a fuel pressure gauge and once I get that reading I'll report back here and then go from that point

    Don't have a fuel pressure guage. Will need to buy or rent one. Then if fuel pressure is good, on to pulling injectors.

    1999 7.4 won't start

    Have tried pushing throttle up. Same exact symptoms. Almost starts on a few cylinders but won't continue on. Never had it running as I inherited this. It onky has 284 hours on boat , was a one owner before me. At this point it seems like it may be injectors as i would think if it was anything...

    1999 7.4 won't start

    Not sure about fuel pressure but when the Schrader valve is depressed gas shoots out. Pump runs when key is turned for like 5 seconds and then runs again while cranking.

    1999 7.4 won't start

    I replaced the fuel filter with a new one and filled it with fresh gas. Took hose off tank and had a one gallon tank with fresh gas that it was feeding from. I don't trust the gas in the main tank and will pump that out and start fro m new later one. I just wanted it to start and while it...

    1999 7.4 won't start

    Hey all I have a 1999 270 DA with a 7.4 mpi. I recently acquired this but do know it wasn't started for quite some time. I have been going thru replacing the various obvious things but when I tried to start it, the motor cranks and almost starts. its got spark and fuel pressure at the Schrader...

    Wet exhaust modification?

    Okay - all of the above was WHY I was asking. Seemed simple but sure enough there was a reason behind it. Thanks all

    Wet exhaust modification?

    Yes there would be water in the system staring at elbow and going out through the exhaust tube out the back of the boat. There would be no water in the exhaust manifolds itself. Yes it might heat up more but cars run manifolds like this for years now.
