Remote Oil Filter Hose Leak - Riser Height? (and other questions)

[Jambrin]

Does anyone know what height the risers are on a 2002 340 DA with raw water cooled 6.2 MPI engines and V drives? I've got an oil leak at the rubber to metal crimp on one of my remote oil filter hoses. It's dripping into the bilge and making a mess. I would like to order the hose and have it for next time I go to the boat, but I don't know the riser height and I didn't know to measure it before I left the boat last time. The options from the Mercury engine catalalog for my SNs are:

32-863806 HOSE Oil, V drive (To Adaptor)(without riser and with six inch riser)
32-863808 HOSE Oil, V drive (To Adaptor)(with three inch riser)

Also, the hose that's leaking is the one that supplies oil from the engine into the remote filter as is indicated by the "in arrow" pointing to the adaptor, so I'm assuming that means I need one of the two hoses above that go "To Adaptor"

Finally, any idea how difficult this hose is to change? It looks like getting to the side of the hose that goes into the engine block will be a bear.

Thanks,
Brian

Attached to the block you either have two components, manifold and elbow at the top, no riser or three components, Manifold, riser and elbow. If there are three, measure the middle one. It will be either 3 or 6 inches. If you are thinking of replacing just the one hose don't replace both. The starboard engine block adaptor might not be accessible with manifolds in place. If you are able to get to it and are replacing both hoses, drain the oil then cut the hoses at the block adaptor and unbolt the adaptor from the block. Now you can get out of the boat, unbolt the remnants of those hoses and attach the new hoses while it sits on a workbench. Take it all back to the boat, replace the block adaptor gasket with a new one and bolt it back up. Now you can just attach the hoses to the remote filter bracket.

OK, just to clarify you are advising that I should replace both hoses, which would enable me to cut the hoses near the engine block allowing me access to remove the block adapter, bolt the new hoses to the block adapter and then re-install the block adapter with the new hoses already attached. Is that correct?

After reading your post and looking at the remote oil filter parts in the mercury engine catalog again I think I was confused on the hoses To and From the Adaptor. I was thinking the remote oil filter was the Adaptor, however that is wrong. The Adaptor is the thing that attaches to the engine block. I was also only thinking of replacing the 1 leaking hose and leaving the other.

You mention draining the oil. Do I have to do that? If so, I might just wait until the end of the season when I normally change it anyway, assuming the oil leak doesn't get worse. I can probably put some oil absorbing mat in the bilge to catch what is leaking until then.
