I changed boats this year. The new boat
has a Yanmar
. The handbook seems quite strict that only Quicksilver High Performance Gear
Lube be used.
I have almost 5 litres of Volvo Penta transmission oil
left over from previous boat
(also Yanmar 3YM30
What damage would it do if I used the Volvo Penta Oil
? Secondarily, does oil "go off" if I have it for a year unused?
