Marine Power concerns

[dogrocco]

I have a 07 24Ve I bought it in December last year, We first put it on the water in April by June we had our 30 hr service. Now we have 90 hr's on it. I just took it in for some service work and one of the thing was the error buzzer. When the buzzer went off I checked all gauges and everything was great. The buzzer lasted for about 5 seconds. Well the dealer just called and said my boat was 2 quarts low on oil. There is no signs of leaks anywhere the dealer said it is burning it. I have never had a new motor burn two quarts of oil. I was told a marine motor burnes oil more than a car motor. I have been around motors for my whole life and have never heard of this.

There is a dipstick recall that your dealer should have known about. I'll bet they under filled it at the last service :02:

[dogrocco]

I asked them that and they said that was checked and mine did not need to be repaired.So what is the averge hrs' for a oil change this year we did 90 hrs.

[chpthril]

1st at 20hrs and then every 50 or at winterization.

[zad0030]

1st at 20hrs and then every 50hrs or winterization, whichever is first.

Chp beat me.....

My dealer recommends every 100 hours or at least once a season...which ever comes first. I have over 700 hrs on my boat and it's not burning oil.

[dogrocco]

I agree and for mine to burn 2 quarts in 60 hours

[dogbert]

Be careful with the oil, there's a dipstick recall on that motor that causes it to read low oil. If you overfill, it's a real problem. Basically, the dipstick supplied was to short.

[dogrocco]

I would have seen it smoking if it burnt 2 quarts of oil. I think they under filled it.

[chpthril]

^^^ hate to say it, but that's my gut feeling.

I just spoke direct to Marine Power on Monday about some other issues and the oil consumption on my 2008 340 hp. They very emphatically told me that they WANT to see oil consumption at the rate of approximately 1 qt. every 20-30 hrs. For what it's worth they said that their motors have much softer rings than a "normal" automotive engine because they want a little blow by for more top end lubrication. Don't know if this helps or not but that's the story I got.:confused:

[chpthril]

Send a PM to MP's rep, tlbarrett, he will get back to you I'm sure.

Mine uses less then a qt between services, FWIW.

I have about 800 hard hrs on my SBC and it uses no oil between changes and I typically change it about every 30 hrs. I sent an oil sample off once couple months ago when it had about 25hrs on that oil change and the oil I removed had some life left in it but not 75 hrs more for sure. I would feel better changing the oil early rather then later and 100 hrs seems like a long time for a marine engine, at least IMHO. I typically change oil more often the average bear because it makes me feel better and oil is cheap...well sorta. I would be curious what an oil analysis report would be for a 100 hr change, I bet it is used up.

I am very skeptical of the MP having"softer rings". As far as I know every marine engine rolls off the same GM power plant line before going to Mercruiser, Volvo, MP or whomever for marinerazion. A quart of oil every 20 hrs is nutz. I would do leakdown test and go from there.

[shake-n-bake]

I have the same boat that you do, an 07 24ve with an mp engine, and my boat was using a lot of oil just like yours, we had the issue with the dipstick at first. After we got the right dipstick in it it still kept using oil. My dealer did a compression check and two of the cylinders were running at about 20%, So they ended up sending a new long block and putting it in the boat. I was without my boat for a month.

[dogbert]

I wonder if the shortened dipstick didn't cause some of this because you would overfill the oil. Either way, it's :bs:

[rushin]

Have I missed something, what engine are we talking about here?

[FIC]

My reccomendation is first 25 hr breakin and then every 50hrs or 6 months which ever comes first, and dependent upon usage the transmission serviced every 100 hrs especially if loading with extreme ballast. Also monitor the temp guage to make sure the engine isnt running to cold, to cold will cause oil consumption, due to improper cly expansion.

[RedBull And O.J. MMMM]

I have had the same thing on my RZ2 (M.P. 340)at 50 Hrs. the buzzer was going off and it was 2 quarts low too! So I am not the only person Good to know.....I think.

[Jetrey]

my last trip out this summer my boat did the same thing. alarm buzzer sounded for a couple seconds and went off. all gauges were ok. and oil level ok. any one else have this happen?

[SPBFAN]

OK, here is my take, I have had spectro analisys done on my engine oil at 20 hrs. 30 hrs and after the 30hrs one I will not go past 30 hrs to see what it is like at 50 hrs. 30 hrs of normal operation average RPM 3500 the oil lubrications properties along with the heat bearing and distribution properties which will prevent burn off were worn out. I have never burned even .5 quarts on my PCM of course I never go over 30 hours for an oil change either. I also use Mobil one synthetic oil and when I store it for the winter I put in a regular Castrol 10W40 motor oil with an oil stabilizer to keep lubrication on the moving parts. Then I use that oil for one trip to the lake at the start of the season and remove it for the good stuff. I have seen spectro analisys on twenty five diffrent brands of oil. Mobil 1 sythetic stood up the best even better than all those off brand special racing oils. Kendall Oil was second place. Castrol 3rd, Penzoil how I don't know :eek:4th, and Valvoline 5th:o. This is my :02: worth. Take it how you wish.

Also for transmissions Dextron 3 as your base oil with the LUBGARD additive to modify the oil for what ever manufacture transmission you own tested out better than the Manufactures $16.00 qt. special trans fluid did. http://www.lubegard.com/

SBFAN
Is the info you provided for synthetic oil, or regular type oils? Also is it on Multi viscosity or mono grade if not synthetic?Also what category was mobil 1 best in?

[teachercop]

If the boat is stored, isn't the oil sitting in the oil pan? If the motor is not operated, what is the value of fresh oil sitting in the pan?

I like the strategy of running it on the initial season run with the stored oil to collect any foreign matter that may have accumulated durng the down time?

[SPBFAN]

gman: I use 15W50 Mobil1 Synthetic. I buy it in bulk it at Wal-Mart they don't always have it so if they do have it on the shelf get it so you have it when you need it.

Teachercop: When oil has been run in an engine it starts to collect corrosive materials and the PH balance of the oil starts to get damaged. It is best to put in good clean oil with new known good PH Balance to protect your engine parts. I don't use Synthetic for storage because it tends to slip of the engine parts because the stuff is so slick. This is also why I use a stabilizer such as Lucas Oil Stabilizer for the winter storage.

[Timmy!]

Wal-mart is the best place to get Mobil 1, they have that 5 quart jug that they run on sale for $19.99 quite often. While I don't use Mobil 1 in the boat, I do use it in my Corvette and when I pulled that engine apart at 98,000 miles it was completely spotless inside! The engine seriously looked brand new, every single rotating part was clean and absolutely no sludge to be found anywhere.

[dogbert]

So, why wouldn't you use synthetic oil all the time?

[mneal]

I could not agree more,
I would be really interested if anyone has any oil analysis reports for a 100 hr oil change what the numbers were. I said earlier in the thread but based on the results of my oil analysis with ~20 hrs usage the 100 hrs time frame is WAY too long between changes. There is a lot of good info around on the web (and bad) about oils. What exact oil is "best" typically turns into a Ford vs. Chevy deal but I think everyone can agree that a marine application is really hard on oils and oil is cheap, so always best to change it often IMHO. If you think you are throwing money aways changing it too much then just get it looked at and that ends the discussion, maybe you are, maybe you are not but then you know for your boat and driving conditions if you are changing too often or not often enough.

I haven't seen Mobil 1 in the correct weight and my engine is still under warranty so I am only running what is recommended during that time.

[gman]

sbfan,
I'm running 15-40 in the boat (diesel) oil but it is also for gasoline engines with the sl, sm ratings. Do you have any info on this type oil and what is your take on it? Mobil 1 also makes synthetic for diesel and its good for gasoline engines also. any info on this oil?Pennzoil makes a 15-40 marine oil that is recommended by PCM and Indmar. Any info on this type oil?

[mneal]

There is a ton of pretty good info on this site.
