Default Scarab II pulling engines

Hey Guys,
I have an 84 scarab II with 454's/TRS drives. I am pulling both engines; Do I need to pull the drives in order to pull the engines? If not, should I pull the engines out with the transmissions attached or separate the two and then pull the engine out? The transmissions and Drives are fine so I would like to leave them in if possible. If you have any special tricks or things to watch out for, please let me know it would be greatly appreciated.

thanks
John

I pull my TRS engines and leave the transmissions in place. I do support the transmissions later on with wood. I have BW transmissions. Not saying it is the right way to do it, but I have done it many times and the hull has sat for 5 yrs this way prior to putting new engines in it. Everything was fine.

Thanks, that helps a lot. Did you take your manifolds off prior to pulling the engines?

I recommend pulling the drives off and then the motors out because you should always reseal the drive to the gimbal. And in the long run its easer. Check your bellows also. Regards Dan

My starboard drive has taken 2-7 hrs to put on, port never an issue. (I have also switched drives, and replaced yoke shaft) I have alignment tools that are perfect, trans tail stocks, new bearings, rebuilt trans. When it does go in it slips in like butter. I will not remove that drive unless it is blown.

I’m the poster child for remove and install of TRS on a 30 foot scarab. There’s no telling how many times I did it. From destroyed engines to broken drives, etc. I still have about 3 new oil seals somewhere, I replaced them on the regular. I have a set of decent 23 pitch quicksilver props I can dig out if they’ll help you.
Tell us more about your boat. Any photos?

Are you running borg warner or merctrans transmissions? Are you running offshore motor mounts or the soft mount stud with removable nut type? Either way the most challenging part is going to be the starboard side of starboard engine. The starter and steering cooler is confined. You will learn to stand on your head. If you're young, mechanical and not claustrophobic I'm guessing 4-5 hours. We got to where we could pull both drives, and both engines in a couple of hours. But that's two guys and a forklift.

If you're running merctrans transmissions you better support the transmission well or you can damage or loosen the doughnut seal that holds it in the gimble. I actually wouldn't recommend that method with the merctrans. Better to pull the drives. You can inspect your U joints, and replace your gasket and seal too. (The ujoints tend to 'splode at the most inopportune times)
