    07 240DA taking on water possibly in multiple places.

    Four months into owning my new 2007 240DA, wet cabin carpet. Off to the dealer, many months later problem found (it took a ton of hours, boat was disassembled to find). Trim tab mounting was drilled too big. Water broke past the poor bedding job done at Sea Ray, ran on the upside of the stinger...

    Losing power 350 mag MPI Horizon 2007

    BTW, if you need to replace it, there's a newer gen 3 that requires a kit to make it work. Check your engine serial number... https://www.mercruiserparts.com/bulletins/001/04/2009/en_01.pdf

    Merc 20W40 Full Syntnetic Oil Discontinued ??

    Working from my old memory, so use at your own risk. Motorcycle oil versus car oil... usually car oil contains Molybdenum, also called moly. It's a metallic lubricant for high pressure. Unfortunately, most motorcycles have a wet clutch and moly and wet clutches don't get along, you can end up...

    8.2 Cat Replacement

    Recently I was looking at a 2010 with twin 8.2's. These had the first gen catalytic converters in the risers. So... what's the opinion on when manifolds and elbows get replaced, do the cats now get replaced too? In curiosity I looked around to see if anyone had any replacement parts to get an...

    Smartcraft Fault - Gages Stuck

    I just stumbled on this and I started it years ago! Over the years, I got to know some of dealer people pretty well. They felt it was actually pretty common. I'm at about 660 hours on the engine and it happens to me probably twice a year. Sometimes it happens in rough water but mostly in calm...

    Re: 2005 340 v 2010/2012 370...same hull specs so I have some upgrade/mod questions.. Lots of engineering degrees, lots of decades as a aerospace structural analyst. I've done everything from all metallics, carbon, fiberglass and a whole lot more. Although I'm not a marine (boat) engineer, I...

    Oxygen sensor

    They've only been sticking O2 sensors in boats for the last couple of years, so it may be hard to come by a definitive answer. However, they've been putting them in cars for a long time. I seem to remember that there's a fair chance of one failing early in the life of a new engine as all the...

    Mercathode - There has to be a better way to make sure it is working

    Aluminum and carbon fiber together? That would make stainless steel look like a holiday. You might be able to design a prop out of Titanium, but it would most likely be cost prohibitive. Look at the pod drives, last I remember most were made substantially from Nibral (Nickel-Bronze-Aluminum) as...

    Selling Our 2005 320 Sundancer Somers Point, NJ

    A bigger issue that I see are the number of people that use MSRP as a reference for pricing their boat. In 2007, discounts up to 40% from MSRP were possible and in later years, even more. I see too many boats where people price them more than you could have bought them new! General rule that...

    If you have a brass raw water pump (Mercury) read...

    The support bearings for my pump corroded, failed, skewed and caused the shaft to barber pole out last spring... serpentine belt came off and set master alarm. My back plate had some grooves too. I smoothed them out with 0 scotch brite and used progressively finer scotch brite to I think 0000...

    refrigerator problem 240 sundancer

    By in front of the fridge, do you mean up high where the door opens, or down below on the floor? I would think the carpet would be wet all the way down to the floor if the fridge were the culprit. If you have water on the floor, there are a number of possibilities. The first thing I would check...

    Some advice about selling

    Your exact boat, '05 320 6.2V-drives, was listed out here last fall on craigslist, it was in great shape, sold in a few weeks for $85k. You can ask a lot more... and spend the summer and perhaps next couple saying, honey, sorry, we just have to keep boating since no one will buy it!

    PCV Valve

    While at the dealer's parts counter... I said, oh yeah, can you give me a PCV valve (I figured why not throw the Merc one on, I've got several years and 370 hours on the engine). He looked at me and said... in all my years, I've never sold one. Neither had the guy that was sitting at a desk...

    Washington State Boating safety card

    A few years ago I took a Power Squadron class and was able to use that for the state boater's card. If most people knew who was the stand on boat and who was the give way boat, things would be a lot better.

    2006 240 Sun Dancer Questions

    No idea about the trim fault. But my '07 came with the factory KEC 7" flip down TV. It's an analog TV, which means last year when we went to digital transmission, I no longer had reception. From my schematics, the antenna is attached and stuffed in the headliner, no way to put a converter...

    240 SunDancer Wet Floor in Bow

    The water I took on was a bit more aggressive, but kept accumulating in the same place. There are a couple other areas that are possible, but were eliminated during the twice dismantling of the interior of my boat (by the dealer, it took then a couple months to solve the problem)... things like...

    Aquapalooza -lake union searay

    I signed up a long time ago... just don't read very often! I went last year, it was a lot of fun. Jumping from swim platform to swim platform can be hazardous in the dark, so be ready. I'd also say that watching some people, you can't bring enough tequila!

    Lake Washingmachine here we come

    BTW, it was me in Juanita Bay... You looked a bit startled when I called out your name! That's what you get for being famous! I went to Aquapalooza last year, it was a fun time... depending on what you're looking for. They were set up in a large wagon wheel. To one side seemed to be quite a few...

    Digital TV?

    I had a copy of the notice that Sea Ray sent out that said they'd swap out the TVs if you bought your boat approximately Oct 1, 2007. I was 6 weeks out and the new service manager is (I won't use the words to describe) so they told me too bad, heard the same from Sea Ray when I pressed them...
