225 ProXS beeps when starting

[MIZ-ZOU]

Background: The motor has given a warning beep about 2 out of 3 times that the motor is started since it was new (2 years). I took it back to the dealer once, where he took the leads out of the power disconnect switch and tied them directly to the battery. No change and no errors showing up on the motor. He told me to ignore the warning, but it still bothered me. I had the battery tested twice and, both times, it showed good. I still thought that it was the battery. Once the motor is started, it runs fine, but it definitely drags while turning over.

A few few weeks ago, I purchased a new Cabelas AGM starting battery that is on Don's recommended list. Guess what? I'm getting the same warning beep. I also set my Lowrance to warn me when the battery voltage drops below 9V, and it does with almost every start.

I have a new battery (charged before use), the motor starter leads are directly on the battery lugs, the ring terminals were cleaned and polished up before putting them on the new battery, and the cables are stacked in the correct order, with the motor leads on the bottom with a SS nut and washer to hold the rings down.

2 weeks ago, I lost my third coil on this motor, so I took it in to be repaired. No errors (outside of the coil issue) were seen. They checked compression (120 psi on each), fuel and air pressure (I think 93 psi air and 102 psi fuel, but not sure without my sheet in front of me), and a total of 113 hours on the motor (over 50% of which were under 1500 rpm). All in all, they said that the motor seemed very tight.

Does anyone have any ideas? Please Help!!

I just bought a 2005 250xs and it beeps when I start it is that normal or do I need to have it checked out?

It should give one beep when you turn the key or push the start button. Any beeps outside of that and there is a problem.

Seth:

Based on your descriptions.... it will be necessary to go through the battery power supply circuit on your boat/engine with a "methodical, deductive reasoning" approach.

This will involve:

-Load testing the battery to CONFIRM it's ACTUAL capacity (not what the stickers say). I would recommend a minimum of 1100 CCA or 870 MCA (leaving some capacity for your electronics).

-Performing VOLTAGE DROP TESTS at various points in the power supply circuit to assist in determining which cable, or which connection point has excessive resistance. (This can also be done with a load tester, if the operator is familiar with the appropriate precautions and proceedures).

-Cleaning of the offending connection, or replacement of the offending cable.

Three most common causes (when cables and battery MEET specifications):

-Loose or dirty POSITIVE CABLE connection at the engine
-Loose or dirty NEGATIVE CABLE connection at the block
-*Damaged or missing rubber bumper where starter triangulates into engine block

*This can allow the starter to bind and drag when attempting to start- causing a severe increase in starter current draw.

Thanks, Don. Since I had the new battery checked the other day, I will proceed to the connections and the starter on the motor.

I will let you know what I find.
