How do I tell which system it is? It's a 2004/5 engine.
Step 2. mentions, Remove
the blue plastic cap from the hose that is clamped to the starboard side of the engine.
It is marked with the running engine flush symbol (1).
The lined arrow on top of the blue cap shows a motion of the engine turning/running. In this case it's shown turning in a clockwise direction indicating it is safe to flush the engine while running.
For those that may be confused with if you should be running the engine or not, it's going to depend on the design of the flush kit you have installed and also the year of your boat. The new flush design that allows running the engine seems to have started sometime in 2003.
A few of the 2002 and under boats has a different designed Volvo OEM flush kit that connects to the engine block as to where the 2003+ boats TEE into the inlet water hose just before the impeller housing....Now just to be cautious with the years mentioned, there does seem to be a small discrepancy online of exactly when Volvo changed to the new design.... So if you have a Volvo engine made between 2002 and 2004, it would be wise to follow the flush hose to see where it leads to whether it be the engine block or impeller inlet hose just to be on the safe side....The blue cap though appears to be the change in design, but still best to look.
For both accurate inspection purposes and older engines that may want to incorporate the new design, Another website put together a parts list with a pretty good photo of where to look (or connect) for the new design. The link won't work here on iboats so the info is quoted below.
