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...

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 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...

One of the engines would randomly stop running at idle. Changed the IAC and foam filter. No difference. Today I put a pressure gauge on the fuel rail, and here is what I observe: At startup, the pressure is steady at about 30 psi. Engine sounds fine. After a few minutes, the pressure suddenly...

I am hoping for some advice on the next steps to take. At the end of last year, the engine overheated and the head gaskets failed. Replaced the head gaskets, new oil and filters and put new exhaust manifolds on (see this link, post 22 here...

Hoping to see if I have missed something to look at regarding low oil pressure. At the beginning of the week, a hose clamp failed on a hose between the engine and the pump. Shut the engine down on alarm. Replaced the clamp. The exhaust elbows got hot enough to crackle some of the paint, but...

For the second time, I have been out cruising on plane, and the gauges all suddenly drop off (no rpm, no volts, pressures, temps, fuel) for just a second, then they return to normal. Engines never stuttered, nothing slows down, and no codes. This has now happened on two separate outings, and...

I am replacing the manifold on my Kohler 5ECD, and want to be sure I am on the right track to properly install the coolant filler neck, which is threaded and made of thin brass. See photo below of the new manifold and new filler neck with the cap. The original manifold suffered some corrosion...

While on plane this weekend, I noticed a new vibration appear suddenly (boat ran great all season). I throttled down as fast as I could, but just before I got down full idle, I heard a bang. Popped the engine hatch and determined that the starboard transmission turns, but it is as if the shaft...

I have a Magma marine kettle grille, and have no love for it. The lowest setting is way too hot, and half the grill surface is a 'burn zone' hot spot. At home I grill on a Weber in any weather (rain, snow, hail) and love it. But I never look forward to grilling on the boat with this thing...

Port/House Bank is two brand new Group 31 lead deep cycle batteries. Stbd/EIM Bank is two Group 27 lead dual purpose batteries installed in 2013. They are connected to an Intellipower PD2040 converter/charger. I have been seeing volts only at 12.4 on the Stbd/EIM bank, while the other bank...

The steps down to the cabin are pretty steep on our 340. Not for the people, but my wife's dog... He is a 14 lb rat terrier poodle mix, and there are times when he stands in the top of the cockpit looking down at the steps waiting for my wife to pick him up. Sometimes he waits, and sometimes...

Need help on how to protect the block. Came back from a day trip on Sunday. Engines ran solid. Shut them down. Came back the next day to flush with these: While the flush was going, the port engine would not start. Stopped the flush. Smartcraft said Port MAP input Hi. Thought the sensor was...

For the cabin galley refrigerator on my 340. The freezer door no longer works properly and flips open whenever I open the refrigerator door. The plastic cam is worn and no longer stays in the slotted opening in the frame so the door only springs open. Would want the door and frame assembly...

From last weekend, Sunday evening. Sun was setting on Commencement Bay in Tacoma, the temperature was mild and the water was fairly flat. I headed out from the Marina, cut the engines, and enjoyed just existing on the water. Not a bad way to steal a quiet moment at this time of year. Way in...

Looking for advice to make sure I am heading in the right direction regarding the drive train for a new to me 2007 340. Had the boat only 4 days and took it out, only to have a sudden vibration come on at any revs over 2000 rpm, port side. Did not see any debris in the water. Was leaking at...

The time has come to sell Ay Lou... https://seattle.craigslist.org/tac/boa/d/tacoma-2000-sea-ray-290/6993458542.html This is a strong, fast, and maneuverable express cruiser, fresh from a trip to the San Juan Islands. Powered by Twin Mercruiser 5.0L EFI V8 240hp freshwater cooled engines with...

We bought our current 290 purposely without a generator (reasons: we like the anchorages to be quiet and enjoy the bonus space in the engine room), and its Kenyon range is dual electric and alcohol. Works great for us. We are thinking of moving up, but all 340s and 320s come with electric...

We are planning a 2-week cruise from Tacoma to the Desolation Sound area in our 290, which does not have a generator. Is a generator a necessity or is it a nice to have for the Desolation Sound area? Our stove is alcohol, not electric. And we carry a propane heater. We do have the option of...

I added a digital to analog converter box to the TV. After looking into postings on this board (thanks all!), anything that makes use of the existing poor, much reviled factory installed antennae makes sense. The converter was from Best Buy, Insignia. It is eligable for the government...
