    What does the red kill switch disable?

    I’m certain it disables spark but does it also disable fuel injector pulse signal or disconnect the ECM somehow? I am looking at a 1999 7.4 MPI.

    7.4mpi just started running rough and with gas coming out exhaust

    1999 7.4mpi 0L854*** 270 Sundancer single engine B3 Just before I was about to pull into the marina on plane my boat started sputtering and missing like it had water in the gas. I dropped it down to about 1k. It idled in running but a little rough. It smelled rich. It wasn’t until I got to...

    Voltage completely drops when switch turned to on - No start, no gauges

    1999 270 Sundancer with the 7.4. I went to start it for the first time this year and got nothing at the helm after the first try. The first time just turning the key on I heard several clicks without turning it past run. I turned it off and back on then went to start it and nothing. I have...

    Anyone have any experience with the Superior brand boats? (compared to Sea Ray)

    I have never heard of this brand. I was looking at a late 80's Superior 21 ft with a cuddy. Nice looking boat with 4 new swivel seats but I've never heard of it. This one has a 3.0 with merc. Seems a bit small but the owner claims it jumps right up on plane and tops out about 41mph. I'm...

    What is the thing on the back of some boats that looks like an extendable square foot

    Noob question, but what is it? It looks like it extends. It reminds me of a stabilizer leg on a back hoe. It is mounted above the water line on the stern.
