Putting this out there for any Merc 4.3 owners who want to make the oil filter change process a breeze.
2008 Chaparral SSi 190 with the 190HP 4.3 engine. Couldn't reach the oil filter because of its location and the design of the back of the boat encasing the back half of the engine. Laying on top of the engine from starboard to port I could jam myself in pretty good but didn't have enough leverage. I figured that if I have to disassemble the back bench to change the filter I'll put in a remote filter kit and be done with it.
Decided against the $350 Mercruiser remote filter kit for my 10 year old boat, and opted instead for the Derale 15717 from Jegs for $40. Bought a couple of iron pipe 90 degree elbows and two nipples of different lengths (see the photo) so I could have a bend where the hoses enter the filter housing. You need the different length in order to properly tighten the second pipe fitting you screw in.
On the motor end used the stock set up as the hoses came up from the bottom nicely.
Marked each end with a Sharpie so I put it together the right way. Filled engine with oil (and filter with a some oil before installing that), ran it and checked for leaks.
Located the filter in a spot where now I raise the sun pad, kneel on the back bench, lift a rear compartment panel and can access it by hand with no tools. room for a bucket underneath to catch the spills when changing.
It takes a larger filter, and there is oil in the hoses, so the motor now takes a bit more oil than stock. Not a bad thing. Just pay attention to the dipstick.
