I understand that its common for boats to track engine hours on a
hobbs or something similar. I just bought a 2003 Bayliner 185. Where
would the meter be? I didn't see anything in the engine compartment or
on the dash. The boat is mostly factory and I have receipts for all
the upgrades showing they were done by the dealer. So I don't think it
would have been removed for something else. There are notes stating
certain hours at service times and from the seller but I'm not sure
where to look for the actual gauge.

Also, I'm curious how you drain the oil. Does it have to be pumped out
or is there a way to actually drain it?
