    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

    Bravo 3 loss of lube oil - slowly then rapidly x2

    Yeah I found heat most helpful doing the upper on my alpha gen 2 . Used a bearing heater to slip on press fit bearings

    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

    Correcting potential bad gear ratio

    yes drop 2" of pitch should put you at the same place. I did a repower where I went the other way- swapped a 4.3 for a 5.0. Kept the 1.81 V6 drive ratio vs getting a 1.62 drive and went from 19" to 21" pitch. Works great

    Cam for 96 5.7

    Those two sources and Powell machine found that heat treating isn't the issue - its that no one knows how to properly machine a flat cam and lifters anymore as no one is making them for OEMs only rollers. Lifters dont rotate and you can put what ever oil, valve springs , etc into breaking and it...

    Cam for 96 5.7

    I was talking about a bunch of roller failures. The flat tappet issues seem to be more from improper machining- no taper on lobe and no convex to base of lifter than break in or oil issues. UTG and M<uscle car solutions did some good videos on how to measure these prior to flat cam install...

    Cam for 96 5.7

    Yeah I know that but this guy doesn't have 30 years of putting motors together, which is often learned the hard way, hence have the machinist do the combo so the OP doesn't miss something If he wants worry free stock performance and a simple build stay with stock components. Melling is quality...

    Cam for 96 5.7

    No you have a 85 and up small block Chevy sure fireway is to get casting number of bellhousing area of block and go off that this is probably the mildest kit they have for cam lifter and chain . May require valve springs and machine ping of spring pocket and retainer to seal clearance but talk...

    Cam for 96 5.7

    Look on summit racing for sbc roller lifters. That’s where I would see what they cost. they would likely offer two style one for block originally set up for flat cams, one for originally set up for rollers. Or call their tech department to make sure what fits your engine
