    What reason causes the water leaking into gimbal bearing house?

    Run Merc 3.0LX on external fuel tank

    Depends on what you find when you empty the tank. Empty all the contents. When I have this with old cars and rusty steel tanks I have used my vacuum extractor to suck it out, put it in covered 5 gal buckets And let it settle out. in my case I let the rust and Schmeg settle, sucked of the top...

    Run Merc 3.0LX on external fuel tank

    Plumb the external tank into existing fuel filter (change the filter). before putting on the rebuilt carb purge fuel line from new tank to carb into a jar, make sure the fuel is clean. Could also take a sample off fuel on on carb before you change fuel tanks by pumping into a jar see if there...

    What reason causes the water leaking into gimbal bearing house?

    that may be , not sure how the water flow is occurring in your scenario? can you describe the part is called an oil seal the video below references the service bulletin about 9 min mark that states grease seal is not needed using the non greaseable bearing, and it is not installed in later...

    What reason causes the water leaking into gimbal bearing house?

    More likely the seal in the shift shaft in the first pic. There is a seal below the top lever. unless the cable is leaking probably not the cable side Either way the quad ring will keep it out of bellows

    What reason causes the water leaking into gimbal bearing house?

    That seal is to keep gimbal bearing grease out of the bilge not bilge water out as there is a small bellows drain hole in transom. This seal is not used with newer permalube bearings. Bilge water if very over full can get water in bellows. To the OP it doesn't look like the gasket (Quad ring)...

    Mercruiser 5.7 EFI Water in Oil

    Yes do both if one is bad. if the heads need to come off I would have a machine shop check them out for straightness (block as well). Have them look through the heads do a valve job if needed and replace seals. Likely they will be ok unless warped but you never know. Check cam and lifters...

    Another gear oil thread... 80w-90 vs. 90

    Yeah not my favorite place but I do get motor oil etc there. There are other places like the local marina but certainly not a ton of spots. I do think the local advanced auto or auto zone may have them too You will likely be fine running 80W-90. I do think amongst marine gear lubes a straight...

    Mercruiser 5.7 EFI Water in Oil

    you could do a cold compression test to see if head gaskets hold. Yes a decent over heat its common to split a head gasket, should see it on a comp test. If you ID low cylinder(s) you could do a leakdown on them to pinpoint source of compression loss. The bolt torque for vortec intakes is...

    Alpha 1 Lower unit. Can’t turn shaft while reinstalling

    Probably not in gear . When shift lever is in fwd prop must be held ccw. Turn it ccw, should stay in gear to twist drive shaft and line up splines

    Exhaust Manifold and Water in Oil

    Water leaks from the crack in water jacket into the exhaust ports down into cylinders where exhaust valves are open when engine stops. fills cylinder and leaks past the rings into the oil.

    Boat age vs financing.

    No boat you will own will ever be 100% what you want, they all have some compromises. Personally I would just save up some money and buy when you have funds. Its a personal choice, from my perspective no sense borrowing money on an older boat that you can only use 4-5 months out of the year...

    Boat age vs financing.

    As mentioned talk to a lender and look at it a couple different ways. One of my co workers could not get financing for a older car purchase (I think its more than 10 years old). He took a personal loan and is paying a ridiculous interest rate. Would think you are better off doing a Heloc or...

    Cracked intake manifold

    I would pressure test the cooling system if you can make block off plates for the water cross over in intake. See if heads and block are not leaking before buying a new intake. Assumption would be that it wasnt properly winterized
