5.0 MPI Intermittent Continuous beep, no Smartcraft output

I want to say thanks to the whole thread, comments, and input from everyone. Based upon this thread, I pulled the hose connection off the housing only to discover the starboard side was half-way crushed in from corrosion. The water pump PSI was a few pounds lower than the port motor and it was exactly that issue. All new hoses put in thanks to this thread. We were getting higher temps on that motor and it was getting worse despite new impellers. An ounce of prevention...

Yes it does! It feels great to be able to run on plane again! I can't thank you enough for you excellent contributions.

Nice! Glad that you were able to benefit from this thread as well! Are the temps on that motor normal again?

  • Don't rush through cleaning the corrosion around the inlet hole in the gimbal housing. I initially gave it a quick brush, and this cost me hours of frustration! I wasn't able to get the new hose and bushing to fit properly and ended up having to take everything out to properly clean the corrosion.

That's what my mechanic said. He just seemed to know that before he started, so he spent a good bit of time cleaning it out before we even tried to install it. I still haven't figured out exactly how the new hose "holds" itself in place. I assume that you had an issue getting the bolts to tighten down when using the tool?

Excellent! I'm glad all of my pain & suffering with this issue turned out to be to the betterment of others. Kinda makes it all worthwhile. Lord knows I've fixed quite a few issues using the info I've gotten from CSR.

I never had a problem tightening the bolts down, my problem was that as I tightened the bolts down the rubber grommet that holds the hose in place would bulge out and pinch between the housing and the installation tool, rather than being pressed into the housing like I was expecting it to. The result would be that when I would take off the installation tool, the grommet would still be halfway out of the housing.

In the end, I was able to get the rubber grommet to seat about a quarter inch from the housing, then I am assuming the water inlet pushed it the rest of the way when it was reinstalled. The instructions are very clear about the hose sticking out a little bit further than the grommet, but does not really mention how far in the grommet needs to be into the housing.

As far as how the new hose is held in place, from what I understand pressing the grommet into the housing puts just enough pressure on the hose to keep it there. Since this is the suction side, there really isn't much of a risk of blowing the hose out of the fitting. If anything, with the engine running the hose would be less likely to come loose.
 
great you sorted it out david !

yes , this thread is full of very useful information regarding bravoitis !!!
 
Hey David, I got mine back in the water yesterday. I've got 3-4 psi at 1200 RPM and 12-13 psi at 3400-3500 RPM. That is right about where they've always been on my boat. I've never seen numbers anywhere near as high as yours, so I guess it's just different for different engines. Needless to say, I am thrilled.

Hey Skibum, really glad to hear that you're back on the water! Those numbers sound great, I'm sure there is a big difference in what to expect from your 496 vs my small 5.0. That PSI issue was extremely frustrating, I'm glad to hear that this fixed your issue as well.

Also, how did the steering work out? Any issues?
 
It seems to be just fine. She's actually handling better than ever. We replaced the aft pin that the trim cylinders connect to because mine was bent, and it seems to have made a significant improvement in slow speed handling. The wandering has been reduced to almost none. I put a couple of hours on her yesterday. I didn't go below to see how my brackets looked when I got back because it was dark. I'll have to stop by one day this week after work and take a look. It certainly doesn't feel like there are any problems with it from the helm.
