I pull slowing out of the water and hopefully the muffler drains as much as necessary gong up the ramp.
The installation and design of the Muffler used in the Rangers and Cutwaters does not drain. The only way it drains is if the owner removes the drain plug located at the bottom of the can.

If that effort causes water to get into the engine, how does one possibly stop going down the road when some other driver cuts you off because they are oblivious to the effort to stop such a load? My dealer does the same thing and no one I know of has ever had a problem with this method
The answer to your question is the same thing could happen in such a situation. Most try to avoid over the road hard braking for more reason than having sea water migrate into the exhaust system and engine. The bottom line is if one does do a heavy high speed braking the possibility of sea water migration does exist.
There were issues with this on early day Ranger models that did not have the " water back up nub" glassed into the muffler can. This helps to stop the water from backing up the exhaust hose and getting to the elbow, Turbo and exhaust manifold. It does not eliminate the chance. The only way to eliminate the chances of this is to drain the can when trailering.
This photo shows the "Nub" below the exhaust inlet to the muffler.

Because a dealer does it does not mean it is right. If I followed all the advise of the dealer I would ...........
If you had sea water migration what issues would you experience? Worst case is the can emptied seawater into the exhaust system and then flooded a cylinder causing a hydrolock if started shortly after flooding. Over time water drains past the rings and causes oxidation of the cylinder walls. This should be detected at some point if enough water was ingested. You must be looking for it though. In most cases I would not expect that much water to migrate but the possibility of water making to the turbine side of the turbo (exhaust side) is possible. This will cause rust and corrosion build up in the wheel area. The eventual failure would be loss of boost pressure. My point is the statement "no one I know has ever had a problem doing this" May be true but sometimes things happen and you don't know that it happened. I have heard of many Turbos failing to produce boost? What was the cause? How many Ranger and Cutwater owners do oil sampling ? If you are one that does and a report elevated % of water and a increase in Iron PPM particulates. What caused this? The next time the oil was changed and sampled everything is back to normal. What caused the increase? Who knows and it is forgotten.
My point, the possibility exists because of the low mounted engine, the exhaust (Muffler Can) close to the engine and the long exhaust hose to the thru hull in the Ranger or Cutwater. For that reason if I am asked the question, in this thread I give my opinion. I would not do the Ranger bump unless I drained the can because of the POSSIBILITY of sea water migration into the exhaust system plus all the other added stresses to the equipment. Sometimes actions done today do not show results from those cations today.They show up at a later time. Preventative is the key word!
S. Todd I respect your opinion and agree it is the opinion of many. I am answering your questions based on my opinion. Right or wrong!
