Weird question but what battery are you running with this new motor?
Weird question but what battery are you running with this new motor?
Dealer installed AGM Interstate. I believe group31. but not sure about size. This is not the first Pro XS 4 stroke they have sold. I assume they know the battery requirements for these Motors!
You'd be surprised .... Just checking, trying to help. We've seen other dealers install lead acid batteries and these engines have issues very similar to the this issue. Also, loss of top end speed. After diagnosing and changing to the recommended AGM, all was fixed. Just sayin....
I do appreciate all the feedback I've recieved on BBC. The first thing I checked when the problem showed up was the battery just to make sure it was an AGM ofthe recomended size. It seems to be charging OK And I have put 2 hrs on the motor before the problem showed up. it still could have a bad or weak cell I guess. Been in the shop 7 days this go round. I'll check on it tomorrow To see what Mercury is saying now.

Little sis, keep us posted please!!!!!
i am still waiting on my 225v8 to come in, I will certainly follow recommendation, but if it winds up being an AGM vs Wet cell, causing the issue, , I am going to need a specialist to tell me why.
i understand AGM more shock resistant, etc, etc,,, but in my world!,(aviation, agriculture) 12vDC is 12vDC, CCA is CCA, and reserve hrs are reserve hours.

Don't know this for a fact as to the reason Mercury recommends AGM. I suspect the requirement for AGM is because at a lower state of charge the AGM will have less voltage drop at the same current draw than a wet cell lead acid battery. A lithium would be even better in this regard, yet they are not approved at this time!
Thank You Leon Pugh

Dealer called today. Mercury is now telling them to replace the shift actuator.I thought it had already been replaced. I stand corrected. Shift sensor was replaced which did not correct the problem.I was also told that the motor was not in Guardian mode. Should get the Ranger back after the 1st. We'll see if they have figured it out.
I know of a few V8 4 strokes running lithium cranking batteries with no issue so far.
The issue will be when almost anything goes wrong. Installation instructions and decal that is supplied in the crate with the engine VERY clearly indicate that an AGM battery must be used.
We've asked about Lithiums- the only answer we're received is a repeat of the above info.

For those of you who have been following my Pro XS problems, here's an update. Picked the Ranger up yesterday. Mercury sent a new Shift Actuator which was installed. Ran the boat a couple of hrs today with no problems. Have ran a lot of 225s over the years. Never had anything with this kind of torque! Very impressive motor. Plan to put some more time on it tomorrow. Will see. One other thing I noticed. A low voltage warning came up on my Hummingbird in dash. This boat was rigged at Ranger. Cranking batt is a interstate AGM 800cca which only meets minimum requirements. I believe I need to upgrade.
Thanks for the update. Good luck
Good to hear, Odyssey 2150 AGM works for me and my voltage use

If you expand your search you can "buy it now" for $389.99 and free shipping. I just ordered one as my 6yr old PM-1 is borderline reliable.

I had the Odyssey 2150 AGM's before the PM1's and now that Sears doesn't carry the PM1 I will be going back to Odyssey. They average 6+ years for me.
