10 hour oil change speed decrease

[HangOutdoors]

@Rockfords Fosgate What are your Max RPM's? Consistently.

For me 40 loaded down would be great.

 

[Rockfords Fosgate]

They sing (scream?) around 7500.

 

[HangOutdoors]

I would take that.

 

[Rockfords Fosgate]

I mentioned it in another thread as well, but I lost quite a bit of top end RPM when my oil was on the higher side of the level (after I did my 10 hr). I pulled some out (low end of acceptable range when engine is warm and on water)...and I regained my RPM and speed.

I am using YamaLube...as I want to retain that 20 year warranty.

 

[HangOutdoors]

I am using Yamalube as well. I am in the middle, perhaps taking out a bit to the lower end may help.

 

[Seadeals]

I think That is worth a try since @Rockfords Fosgate experienced that. The TR1 is different from the MR1; but my goal is to just register on the dipstick when running but still cold...definitely not past the half way point.

The fastest my 2019 AR210 has ever gone is 46MPH, and that was registered by the boat dealer in their pre-sale checkout. It now routinely sits at 40 (5 people, gear, full tank, tower speakers, anchor, extra battery, etc etc.

I'm at 1100 ft elevation...

My 2020 AR210 shows top speed of 46.1, pretty sure that was clocked on the delivery truck, cause I haven't seen over 41.

Sorry, not a lot of help with this post and a bit different boat. But, I did my ten hour with all Yamalube products (oil/filter/grease) and no issues. Different engines I know, but they are hitting 7500-7600 RPM at WOT and a bit over 50 with a couple of people in the boat plus nearly full tank of gas.

As much as it sucks to do it might be time for a trip to the dealer to see if they can figure it out.

I plan on testing on Sunday morning hopefully. I am going to double check and redo the following for testing purposes. Looking for the 500 RPM's or so that I am not getting.

1) Don't eat any food the day before or in the morning to bring the weight down.
2) Just myself and the Admiral.
3) Full tank of Gas, no additives. 87 Octane from Mobil Gas Station.
4) Already reviewed and adjusted the throttle linkage just a bit in the engine compartment on one side, there was just a hair of slop.
5) Make sure everything is removed that wasn't in the boat on pre 10 hour oil change testing.
6) Bimini Top Down
7) Will Draw down oil till just above the "L" hash mark Cold. It is half way now.
8) Will also bring 2 quarts of oil to check and add if needed when hot to make sure.
9) Top of boat above water line has been waxed and shined. Bottom of boat below waterline has been cleaned, no wax.
10) Spark plugs, the new set, have been removed again and all Gap's have been checked and Verified.
11) Will hopefully get similiar water conditions, albeit about 6-10 degrees warmer with low to no wind if possible, light chop. (Same as original test)
12) Double checked alignment of Jets.
13) Will test with both air filters in and then with air filters out to see if it makes a difference. Although I don't see oil in them I will verify.
14) All plugs will be in and I have lifted the tongue up high to verify I am not carrying around a bunch of water.
15) Oil change and filters were all from the Yamalube Kit from dealer.

So this is the plan. If anyone has any further suggestions let me know. Don't get me wrong, it has plenty of punch and pulling power, it is just the top end has come down and the RPM's that I originally hit at 2.5-3hours were 500 RPM's higher.

Will definitely post my results and shoot a pic of speedo and RPM gauges.

Goal is 7600-7800 RPM's and Circa 43 mph on Speedo, which is where it was at. I will GPS verify as well.

If the results are less then optimal, it will go to the dealership.

In the end I want to verify that I didn't mess something up, and that my boat is running at what is should be. Of course it is what it is if everything is Ok.

As an FYI, all the lakes around here have a 40 mph speed limit and unless you get lucky in Lake St. Clair you aren't running WOT because the chop will beat you to hell as well as your boat.

Sounds solid. Looking forward to the results.

Does the 87 have ethanol in it? That's the only possible suggestion I can see as I run 91 ethanol free/non oxy as we call it here in our boat.

 

[HangOutdoors]

Don't know but will check.

 

[minn19]

Don't know but will check.

I'm unsure how the ECUs work in these engines, but I was very surprised the dealer said to put 87 in. Coming from being around the performance car scene for years no one would put that in their car. The ECUs will pull timing (less power) with the lower octane present in cars with high performance/high compression/high strung engines, which I'm guessing especially the 210s (and 212s) are to make the advertised power they do. I use the 91 ethanol free and as I said and my boat performs great. Again, I know my engines are different/more powerful in the 212, but with the bimini deployed plus full tank of gas and 4 adults/two kids I have to watch that I'm not going over 45 to exceed the bimini speed limit. Even with the 210s being lower powered your performance sounds abnormally low, even with a fairly loaded boat etc. Maybe I'm wasting money on the gas I use, but with all of the other money I/we are spending on them I'm not bothered paying a few extra bucks for better gas.

A couple things:
1) On the 2020's, our boats have gps speedo. Doesn't hurt to verify though.
2) Play with keeping your window/windbreak door open or shut. Not sure if there's additional drag gains.
3) Make sure you have enough room when looking for top speed. I know I need A LOT of river to get to 48mph.
4) While boattest.com rates my boat at 51mph, I've never got over 48.5. Flashed 49 once. However if you listen to their video, they have full fuel and two passengers. That's it. No anchors / coolers / water sports gear / speakers / amps / etc.

As you can see from their charts, Yamaha 212 Limited S (2019-) | BoatTEST, 7573rpm was the highest they registered.

I was pretty sure that the spinning wheel under the bottom of my boat at the transom was the speedo in my model, but I could be wrong.

Manual says 87 octane and 10% corn is fine. My 2020 212S loaded for a day regularly sees 45, 48.5 was the high with just my wife and I (but coolers / water sports stuff / custom 12" box / tower speakers / 2x JL amps / etc.)

I was wrong once in my life, this could be #2 - do you have the little GPS puck in front of the drivers windshield?

 

[HangOutdoors]

I don't think so. I have spinning gear under the back near the transom on the bottom.

I know and it really surprises me. I also know they can tune it for that kind of gas, but everything I know goes against using that in these types of engines. With my wife, 9 year old daughter and loaded with a cooler/snacks etc plus some water stuff hit 50-51 regularly with bimini down. Bimini up and 2 more adults and their kid plus more stuff we can still hit 48 etc. No fancy stereo though a bit jelly about that......

With the TR1s making more HP per liter/higher strung, I'd figure they would be more sensitive to octane/lower quality fuel. I could be very wrong though also.

Now you make me want to spend some $$ on some high octane just to test...
