This looks like the "Mercruiser hypercomplexification drainage system" on my engine. I drained the water from the component circled in green. According to the part diagram/list #10, highlighted in yellow, is the "HOSE Cylinder Block Drain". To me, this indicates that the block water is...

I'm on the Chesapeake Bay in the middle. Low temps next week will be in low 20s with highs in the mid 30s. I'm not sure how cold and for how long temps need to be to potentially cause problems with water in the block? Any thoughts?
There is no clog. My engine doesn't have blue wing screw plugs under the manifolds. the hoses under the manifolds all lead down to an aggregation point on the lower front port side of engine. That aggregation point has a blue wing plug that drained.
Yes. Blue plastic wingnuts with threads but mine were not under manifolds. One was on port down low where hoses came together. Two on starboard near water pump? One up top on center forward area. And one on cool fuel module. Drive is underwater but ill look for the winterization guide. Thanks!
I have 2005 MAG 350 MPI engine S/N 0W067905. I have my Cool Fuel module removed so I cant run engine to winterize by flooding engine with antifreeze. I removed the 5 blue plugs from the engine to drain cooling water. I am concerned that the engine block still has water in it. Do I need to...
Did a compression test today. 170psi pn all cylinders. Was going to do leak down but valve cover removal is difficult because of fuel rail/exhaust headers. Will use borescope later to confirm TDC.
Pulled the CoolFuel module. Will take home and disassemble and check interior paint. Broke...
I verified the fuel pressure gauge this morning against a couple other gauges and compressed air at different pressures. It is accurate.
Heads/valves were serviced because two valves tuliped and engine wouldnt run right. Cleaned injectors while heads were being serviced.
Ill have to rig a...
Fuel pressure did not exceed 44PSI (it was 35psi) so I proceeded to step 5. With engine running and fuel valve shut off, fuel pressure stayed at 35PSI as vacuum on fuel inlet increased. Fuel pressure eventually dropped as engine started to sputter because of lack of fuel.
13v dc on Cool Fuel electrical connector.
Ran fuel vacuum and pressure tests.
Fuel source test 5d showed 1-1.5 in hg vacuum (within spec).
For 5e test, restricted fuel supply and vacuum eventually reached 12 in Hg while rail pressure was 36psi. Rail pressure eventually dropped to 15psi as...
Thx. I found that advertisememt on a site but when I click through, it says item not found. If i can figure out the size and thread on existing connection, can i just insert a marine grade fuel cutoff valve?
