I am getting things ready to winterize my boat... After the oil is drained it is recommended to turn over the engine in "drown mode" to draw more oil into the sump.. On the boat you can not move the throttle forward with out the boat placed in FWD or REV.. and the boat will not turn over without it being in neutral.. So how do I crank the boat in drown mode??
 
You have to hold the throttle on the engine itself, to all the way open. You may need the assistance of a second person to actually start the boat, while doing this. When it senses that the throttle is open, all the way, while trying to start, it turns the motor, but does not send fuel or create spark. The manual states that you should do this a few times, to get all the oil out, before changing.
 
Thank you for your help... With a bit more searching I found it in the repair manual....If any one else would like to know it is actually in the driver helm

To activate DROWNED MODE, proceed as per following
steps.
1. Ensure engine is OFF (both engines if applicable).
2. Install the tether cord on the engine cut-off
switch.
3. Select idle and neutral positions.
4. From the driver's console area, move the throttle
accelerator sensor (TAS) to the wide open
throttle position (WOT) and HOLD.
NOTE: For TAS access and identification, refer to
INTELLIGENT THROTTLE CONTROL (ITC) subsection

This astounds me, I've never seen a boat you couldn't apply some (OR WOT for that matter) amount of throttle while starting the engine. Strikes me as bizarre, not saying I don't believe you though, others have mentioned this as well.

Thanks for posting your observation.

Its mechanically interlocked at the levers and is easily overcome using the TAS.

It is important to note, as you did, that in boats with the Bosch ecu (throttle by wire), the throttle acceleration sensor is under the helm, not located at the throttle body in the engine compartment.

I use a zip tie to hold it at the wide open position when winterizing, and cut the zip tie off when finished.

I have the same boat you have 2010 Challenger 430hp, I'm a little confused is the 'TAS' in the engine compartment? I have winterized my PWC's many times and its simple as holding the throttle wide open for drown out mode.

The TAS referenced here is in regards to a 2012 speedster 150 which is the first (speedster 150) model using "fly by wire". The cable from the throttle lever is converted to an electrical signal via a sensor that's mounted *behind* the instrument cluster which is easy seen when the helm compartment is opened.

Thhe 2010+ 210 Challeger has the throttle-by-wire system that gday describes. I believe it was the first year that any of the boats used the Bosch ECU.

Pusing te throttle lever forward without e engines running doesn't do anything (except keep you from cranking the starter). The sensors that keep the engines from starting out of neutral are in the throttle lever assembly. The TAS is behind the helm, so drown mode using the throttle lever doesn't work.

Perfect got it, I assume you have to hold one TAS wide open for one engine then the other for the other engine? or do they work together?

This is the fly by wire system on the 210s. It's behind the curtain that covers the rear of the helm accessed from the starboard bow seat back cushion.

There is only one TAS for both engines. The engine syncing is done by the ECUs. No individual throttles.

Edit: Actually, I'll need to check that. I know I only need one tie-wrap, and there is one cable from the throttle lever to the TAS, but there may be two sensors.

That helps, one tie wrap is what I will use! Looking at the drawing there seems to be two TAS's and possibly a pin that goes through locking the sensors together.
Thanks for all the help, just want to make sure I am totally prepared to winterize in the next week or two. Seems these boats only have slight differences in winterizing procedures over my PWC so that really makes things easy!
 
You're going to move the pin circled in this pic to it's maximum point of travel, then zip tie it there. There may be 2 sensors, but there's only the 1 pin worry about.

I’m going through this process right now as we speak, on my 2010 210 challenger 155 hp. Here are some pictures of that throttle pin underneath my driver console prior to zip tying it and then after zip tying it. I can also confirm that just holding the throttle lever at wide-open throttle and trying to start, the engine is not allowed to turn over. However, doing this procedure and zip tying this pin wide-open then does allow the engine to crank in drown mode.
