Bought my boat a few months back. Its a 2002 Monterey with a Volvo 5.0GL-A motor and a SX drive . Has about 75 hours on it and all maintenance was done by previous owner with receipts, but receipts don't show what oil and gear lube he used. So, I looked threw the site and I am finding a lot of mixed ideas on what to use. Should I lean towards the OEM Volvo stuff or can I just go with any brand but the recommended in the owners manual ? Manual says for motor oil use SAE 20W/50 or SAE 15W/50. For gear lube it says API GL5 SAE 75/90 Synthetic oil. Now, this manual is from 2002 and things change, so I'm really concerned on what to use and not waste money on unneeded full synthetic oils if I don't have to, plus I have no idea what he used since he just paid the local mechanic to do it every year. Thanks in advance......
