Volvo QL Bow Thruster
I own a 2003 Carver 444 with a Volvo QL bow thruster. Volvo Penta no longer offers QL bow thruster oil (part # 41100129) and they recommend using Castrol Alpha SP 150 or equivalent gear oil. I cannot find Castro Alpha SP 150 or what an equivalent product might be. Does anyone know what oil to use and where to get it?

Re: Volvo QL Bow Thruster
How about using a synthetic 75/150 gear oil? I find a straight 150 weight oil is very thick.....
