I will see if I can rig up a fuel pressure gauge- I assume the fuel pressure is a constant and what goes through the fuel rail is regulated? The pump I replaced is connected to a line going into the fuel filter so I guess that is the boost pump and not the high pressure pump- it just stops...
@alldodge thanks for the reply- so when I push the mercuiser down it does zip- no rpm's- like you did not do anything.
So I got the boat out by myself for a couple of hours- same program except when I put the throttle down, it went like normal. Ran across the lake waiting for it- never...
Isn't that the way? Boating not for the faint of heart unless you are rich- I'm not.
2006 350 mpi/bravo III. Around 350 hours, 270 Rinker.
It does not get run as it should, but has been running nice- and everything else- but then it does not.
Replaced plugs,cap and router probably 30 hours ago...
I'm in Central FL- barley hot any rain, had some strong wind late evening but that's about it. They were predicting much higher wind but it just did not happen.
Our express cruiser has a water system for sinks/little shower etc...stopped working. Pump is probably 4 years old, not used heavily.
I turned the switch on and probed the two wires going into the pump and does not seem to be getting power. I pulled the panel off and oh my- I expected a simple...
Hey @alldodge - I'm in Central Florida a little North of Orlando. I did not realize you were so close- you can just come over with your newbox next time I need help!
We have had little from the storm- supposed to get some bands/wind later this evening...around 6 pm now.
That armpit of fl is...
So...after replacing my start battery, everything works as it should. Even took down to the ramp and barely even heard the starter before is was running smoothly.
Did find one interesting "junction box" of sorts I don't see in any of the manuals. I'm fresh water cooled, lots of hoses on the top...
I did get a manual so I can see everything in the starter circuit. Big help for sure. Only issue I see is, the wiring shows a red coming off the same post as the battery feed picture above going to a "circuit breaker" which I assume is the breaker on top of the motor with the red button...
I've been posting in the merc sterndrive section and getting lots of help from @Chris1956 on this and other issues in the past. I really need a good wiring diagram so I can understand a little better the merc engine wiring /along with the help from Chris and others. I probably have very basic...
Thank Scott- I looked over the merc stuff- I'm remembering years ago Chiltons was the go to for service manuals which had lots of instructional / troubleshooting info- are the merc manuals for the home warriors trying to figure out a problem or more for a mechanic that's had the training and...
Thanks- that would be very helpful- I bought what I thought would be a good manual- but just to generic. I will get the serial number and get back to you-
Thanks again-
