- Well, no sense putting it off. I found water in the combustion chamber of Cylinder #7 so the engine has to come out for a rebuild. The engine is a 5.7 Mercruiser small block Chevy with an Alpha One Gen 2 outdrive. The boat has 1000 hours on it so its getting pretty tired. This video shows how to remove remove a Mercruiser engine from a boat for rebuild.

"Cool free tools".... gunna need it for that Chevy you got there. 😉
For sure. Lots of work ahead.
I did the same mistake of connecting the chain to the same thermostat housing eye and I found out that is not intended to hang the whole engine because it could cause damage to the engine. There is another lifting eye next to it where you are supposed to connect the chain.. To late for me, hopefully didn’t cause any damage, and I also remove the log bolts, hopefully I can put them back and they don’t get loose.
I found that out after the fact as well. It didn't hurt anything on my engine but with the manifolds on the engine they are surprisingly heavy. I guess that lifting eye is for aligning the engine. Basically you bolt in the back of the engine and then lift with that eye so that you can get the front mounts set up. Everything worked out though regardless.
Merci beaucoup ❤❤❤❤❤❤❤
You're welcome.
been there. i would take the outdrive out first. i would not loose the two lag bolts of the engine mount, when you tight them up in the future, the threads in stringer can come loose. this happened to me. i would just loose the top nut on engine mount. did you try to turn the main pully by wrench?
I left the outdrive in for now. It's out now actually but I took the engine out first. I tried to spin it over but it was just tightening the center nut on the balancer. I was afraid it was going to snap off in the crank. 😬
💯🔥
Man it was a project haha
I understand you motor is from a 1995 boat, but what year chevy motor is this motor based on? Is it based on the 1986 motor? i thought the newer ones are tbi
I'm not sure exactly. My understanding is the boat engines run a little behind the Chevy automotive engines. I believe you get a mechanical fuel pump, non vortec, hydraulic roller camshaft 2 bolt engine you can look at like an 88-90 or so Chevy pickup. The block number on mine is 638. Hope this helps. 🤞
Yeah outdrive off first. You’ll never get it back in with the outdrive still on. The tabs on the flywheel cover you mention that don’t do anything aren’t used in any boat this is just to mount the engine to the shipping crate. You can also put it on them on the ground or screw it to a pallet or dolly to run it out of the boat . Good thing to do with any engine before you drop it in.
Ya the outdrive is out now. It has a worn out gimbal ring so I'm working on that now. I'm behind on my videos. 😢
That's interesting though. I was wondering what those tabs are for.
Thanks bro video helped alot I didn't know the 2 pins released the engine I have mi e tore down alot more than yours.
Ya once you see it it actually makes a decent amount of sense how they did it. Don't need to strip all that much to remove or install the engine. Glad to hear it helped you!
Do you know any trick to get those risers out?
You are just trying to remove the risers (elbows) and not the manifolds? If so, for me, I loosen everything and then pull the risers forward and off of my captains calls. Might be a little different setup on your rig.
I have a MerCruiser 5.7 Lt Carburettor 350 Magnum and i have a problem with the Thermostat Housing which is cracked ! Is there any spare part or someone i can talk to ?
I don't have any spares. Which part is cracked?
@@605BOLT The Thermostat Housing
@@605BOLT It is exactly the same as the one in your video
@@stefanosk2700 is the center section cracked? Or the top cover?
@@605BOLT all the part is cracked... the thermostat housing part is crached in 2 pieces because of the salt water probably and the years! It is model of 1993 with only 200 hours .. the engine is in a brand new condition because i do my services every year . The last 6 years it was inactive
