replacing 4.3L, need advice, tips, suggestions
I recently bought a 19ft Stingray SS in pretty much perfect condition
except for the engine. It has a cracked block. I've ordered a replacement long block 4.3L marine engine. It should be here in a couple weeks. I've never replaced the engine in a boat before. It looks pretty simple and straightforward. But I have never seen how the outdrive attaches to the engine. Does it have a torque converter or something back there that just slides out? How are the engines and stern drives connected? If I undo the bellhousing bolts it should just pull apart, right? Any special advice or tips that would help me along? And where do I look for the replacement gaskets? Is that something my local boat dealer could get for me? I would suspect so, but it never hurts to ask. Last of all, what should I use to actually remove the engine and place the new one in? The boat is way too high and big to use an engine hoist. It's not really possible to make a crossbeam and raise it that way since I have no access to large enough poles and wouldn't be able to put them in straight and all anyway. Would a rented backhoe type tractor do the job? How much does a 4.3L marine engine weigh anyhow? TIA |

You should get a manual, clymers is ok. First you have to take the outdrive
off. You can't take the engine out with the outdrive on. It has in input shaft that slides into a coupler on the back of the engine bolted to the flywheel. You take the outdrive off the back by detaching the 6 nuts on rear of the top section and the two hydralic rams. Make sure it is in forward gearl. Pull it straight out. It's heavy so have someone help you. You leave the bell housing on the engine when you pull it. There are two long bolts on the rear sides of the bell housing. Remove those. Remove the nuts on the side engine mounts. If you're doing a long block any v6 gaskets will do. The main difference in the gasket sets for maribe is ss head gaskets. The egine is heavy cause you have it plus the flywheel, coupler, and bellhousing. You need a lift high enough. When you put it back together you will need an alignment tool to adjust the engine position so the outdrive lines up correctly. That's why the side engine mounts are adjustable up and down. Cracked block usually means it was not winterized so remember that at the end of this year :-) "Ookie Wonderslug" wrote in message ...

go to mercurymarine.com or your local dealer and purchase a manual for your
engine drive combo. It's the best $60 ever spent! "Ookie Wonderslug" wrote in message ... I recently bought a 19ft Stingray SS in pretty much perfect condition except for the engine.

Is the Mercury manual better or easier to use for the home mechanic than the
Clymer? Mike "Lost In Space/Woodchuck" wrote in message ... go to mercurymarine.com or your local dealer and purchase a manual for your engine drive combo. It's the best $60 ever spent!

The mercury manual is the best but typically the clymer is half or less
than the price of the mercury manual and is almost as good. The clymer is a bit more geared to the diy boat owner. It is helpful to have a manual as there are a number of odds and ends that you would not figure out just looking at the thing. Like the "you need to have it in forward gear when you try to remove the out drive" bit. Christine wrote: Is the Mercury manual better or easier to use for the home mechanic than the Clymer?
