Hello all, as it's getting closer and closer to season crunch time has begun. I have 2004 malibu response lxi and noticed last season that one of the interior lights was out so I decided that I was just gonna replace it with leds all the way around the boat. The boat is currently in storage and was unable to find out what kind of bulb it is. I couldn't find anything on the internet about what kind it is but when I searched it this is that came up for amazon and was wondering what size was the correct one or if it is the totally wrong bulb.

The heaters on a closed cooled motor use the same antifreeze/coolant in circulation as the motor. We happens on the motors is that they are shipped with the correct amount of coolant, but when the motors and heaters are put into the boats at the factory, the heater will take about a gallon of coolant away from the total amount as it pulls into the hoses and heating element. When people add straight coolant its thicker and causes flow issues. We always have to top off the coolant/antifreeze in the newer motors, with the correct mixture.

Sure, when the boat is new, it needs to be topped off because of filling the hoses and core in the heater system. Once it is properly filled the first time, it should maintain that level (except for the ridiculously tiny amount that can evaporate out of the expansion tank over a significant amount of time.)

It doesn’t, however, consume coolant from the system, just because you use the heater (which was the statement I was addressing)

Hey Malibu Crew, just joined and wanted to say hello!

I have a 97 Sunsetter LX that hasn't' seen water for about 7 years. But it's getting back into shape and ready for the lake / river this summer!!

Here's a pic from when it was just about new in 1998

The heater absolutely does not consume coolant. Also, an exhaust boot failure will not cause the closed cooling system to be low either...……

As far as the boot failure, if its an Indmar motor, that leak and the way the water flows through those boots, if misaligned, will cause the exhaust manifolds to get hot and possibly cause and overheat shutdown. But the manifolds are not part of the closed cooled system.

you might have trouble finding those letters.  Maybe just find similar font?  https://www.ebay.com/bhp/chrome-car-letters
