My old eyes may be deceiving me, but looking at the pictures of your boat in the 370 Venture thread, I am pretty sure you do have CR engines. Your starboard engine appears to spin clockwise, and your port spins counterclockwise...
if its anything like my boat, there are 2 seperat sensors, one for the guage, and one for the alarm. so chance of both being bad would be unusual (you said you heard the alarm, then noticed the gauge was high). I would have thought the dealer would know that (but maybe your boat uses one...
depending on the pump, it could also be an all in one unit (no seperate float switch). there still should be a "manual" slide on the boat though (as stated above), so that you can test the switch.
if it is like my 2000 5.7, do you hear the fuel pump at key on? if so, did you check that there is fuel pressue at the rail (there should be a shraider valve where you can measure the pressue)? you would have to have the manual for your year/model to figure out what that pressue should be.
the battery exploding could have just done it on its own. we had one explode on a 3 week old Volvo sedan one time. I thought someone was shooting at me. dealer said it happened every once in awhile. we never had another battery issue in the 220k miles we owned the car.
i have the heatercraft 3 outlet heater on my ski boat. it rocks during those cool NE morning ski runs...driver stays nice and toasty. and after skiing, wrap yourself in a towel and stick the extender hose (which blows warm air) into the towel, and you warm up quickly.
that was probably 20X speed, they really take forever to cross, and that was actually time lapse of a full day :-)
the amazing thing about that is go back and look at the condition of the cars. they all look like they are pretty much dent free.
my malibu is a '00, and I just happen to have the original book that lists all the options. I have the upgraded Indmar Monsoon II engine (325 hp). the corvette boat that year is listed as "based on the C5 corvette, including a Callaway 383 Natural 400 HP". I have seen a couple, all low hours...
I think it was used in special edition Malibu ski boats too. The link below talks about a newer version using the ls7, but I think the lt 5 was also used previously.

there are a couple good reasons to disconnect. one is a short in a wire could cause electrical issues to your vehicle. second is, if you don't have sealed trailer lights, and the bulbs are hot (i.e. you had your lights on), the bulbs can pop when hitting the cold water.
as far as the surge...
OK, I am going to be the ignorant one, and ask this question. How come my ski boat, which is a single inboard, has a combo throttle/shifter, and it appears this boat has the same (except for 2 engines). Yet most bigger boats have separate throttles/shifters. What are the advantages of the...
you are correct. once you have the 5 wire connector, you don't have to have the lights on. when they showed you the trick of reversing the connector and turning the lights on. that activated the brake diabling by using the 12v coming from the vehicle lights.
one thing to consider with the jet is if you are planning to trailer or leave it in the water. jet boats on our brakish river here do not fair well, unless lifted or removed on almost a weekly basis to keep the jets free from growth, barnicles and corrosion.
