Transom stress?

[edseed]

I am having to replace my 5.7 engine in my 2100 sr. i have to transport the boat with the engine in it to the mechanic then have him help me take it out. He cannot store the boat on his lot so I have to take the boat back home. My question is, is it ok for the transom to leave the out drive connected during transport or is it better to remove it? My concern is the weight hanging off the back of the boat. Thanks in advance.

Lots of boats are trailer with so the outdrive weight is not an issue. There are support brackets to take the load off the rams.

Frankly I would pull the drive myself and save the labor if you know how to do this.

My concerns are once the engine is removed will there be added stress on the transom because the engine is not providing the counterweight? Or does it have enough support from other means?

The engine shouldn't be bolted to the transom, the weight should be sitting on the motor mounts on the stringers. There is no stress placed on the coupler. Essentially, the engine is not counter-balancing the weight of the outdrive. The same amount of stress is placed on the transom assembly and transom regardless of whether the engine is present.

I think what Mike is trying to say is remove the drive at home, then drive the boat to have the engine removed. Otherwise, you are removing the drive, then removing the engine, then re-installing the drive alone, then driving back home. When it comes time to install the new engine, you're going to have to remove the drive again, then install the engine, then re-install the drive again. You've uninstalled and re-installed the drive twice for this operation.

Removing the drive will not add stress into the transom.

Removing the engine will remove static load from the transom.

The transom and stringers are designed for high loads when the boats is being ran in the water so what you will be doing has no impact.

Cool. Thanks. I stayed out late and removed the out drive. Is there anything else I need to remove like the Bellows? I already have everything off the engine block except the piece directly behind it.
Thanks again for the help.

No need to touch the bellows unless its time to replace them.

At this point its a matter of disconnecting the fuel, control cables, exhaust. electrical, front and rear mounting bolt then yank it out.

Thanks a ton. Should have the engine out by tomorrow morning. Then re-installed in a couple weeks. Hopefully we'll have it up and running before too long.
