My port side 8.1 was replaced last year with a long block (Michigan Motorz), and all has run well since. I have noticed that on startup, a good amount of rust colored water comes out the exhaust on startup on that engine. I know a little is normal for a boat in salt water, but I see much more...

Your boat is not the same as mine, so I can't give you the part I use since it may not be right. But, if you go to mercruiserparts.com and enter your engine serial number in the the 'Search By Serial Number Box' at the top, that will lead you to what you want.

Need to know what year. I can't tell from your signature.

Only shows the beginning (it was much worse further down), so not the best, but see the third picture down in post #24 of this link, gives a clue: http://www.clubsearay.com/index.php?threads/water-in-oil-340-with-8-1l.112343/page-2#post-1392409

This is good advice. On my boat, the small exhaust that connects to the side outlet had the inner lining come away from the outer lining. Instead of a circle, my exhaust was only able to go through a thin crescent moon. It was not until I removed the whole exhaust line and looked through it...

Yes, still happy with the fridge! It is more quiet than the original. Just pulled cold beers from it this weekend.

Glad you found it and thanks for follow-up to close the thread for someone to learn from. An entire generator does not work based on one of the least costly items...

Quick question: Are both of the 8.1 engines standard CW rotation?

It has been a tough year boating wise. While working on the fuel system on my 8.1, I hydro-locked the engine on fuel. Learning the hard way is expensive. Now, I am working through options on repair or replacement of the engine. Has anyone used Michigan Motorz, since that seems to be the...

I would also suggest visually verifying that the injectors close prior to dropping them into the intake manifold. Liquids don't compress...

I believe I should wrap up this thread. I will likely start a separate thread about what to do with the hydro-locked engine. Regarding the fuel pumps, the set from S & J Complete Fuel Injection Services was actually pretty nice. If I pull the vacuum, I get 40 psi on the fuel rail, which...

Yes, I was able drain the gas, and was able to crank over without plugs, then put them back and got the engine started. But there is a noticeable metal on metal sound (more than valve train); the sound follows the RPM. Compression test was okay, and leak down test was okay at that #8 cylinder...

Things have not gone as I had hoped. Got the replacement seal, and put the pump together, reinstalled, and dropped the fuel rails back in. I keyed it on and pressure came up, then dropped. I keyed again and it happened again. This was new, no leaks were observed. What I should have done is...

Take a close look at the exhaust manifold, since it is possible that may have been the cause of your failure. You will already have things apart...

I noticed that my float switch was not making the main bilge pump run for my 2007 340. I pulled the switch, and cleaned it with no difference. Pump would not run based on manually manipulating the switch. The switch at the helm does operate the pump. So the helm EIM circuit and the pump work...

The starboard side system in the photo now works beautifully. The port side had slightly lower pressures from the gauge; the engine ran fine but the gauge was telling me I needed to do more. I took the pump assembly out and apart (again), to find out that the rubber inlet seal to the low...

Took it all apart and re-aligned. No leaks.

Ok, new problem. The fuel rail leaks at the cross fitting. See photo. How do I deal with that?

Got the pumps put back together last night. I filled the filter bowl and the pump bowl about 1/3 of the way up with fuel so the pumps already have fuel at startup. Will get them installed this weekend, and will fight to get the fuel system re-primed. Let me know if there are any tricks. Pump...

Paint coming off the bottom of the top cap assembly. The previous owner claimed he had it the cool fuel 3 replaced under the factory replacement program. That doesn't appear to be correct, or the replacement was not good. If you look at the top picture, the shoulders that support the low...
