The boat is a '95 but has a '05 4.3 merc. I just picked the boat up from the dealer. I got back from using it and noticed the reservoir on the top right side of the engine was dry. I assume this would be the gear lube. The boat did not sound any alarms or anything and seemed to be running fine while i was out there. i also did not her the alarm go off when i started the boat like a hear on my other boats. Does this boat have an alarm for the gear lube? or an alarm for start up? if i was running on low gear lube what kind of problems will it cause? Would i have noticed anything while driving out on the lake? I plan on filling it up tomorrow with gear lube i would just like to her some thoughts before i talk to the marina. Also what is the stock recommend gear lube? i was thinking the high performance.
