hi i just bought a 19ft glastron mercruiser 165 with cracked block and want to put in another engine. can it be removed without taking off sterndrive? and how does the engine actually connect to outdrive? coupler, torque converter? ive never done one before and would really appreciate any help. thanks ken

Yea, you can probably get off without damage when removing the drive, but to put it back in, you MUST have the drive off and all the pieces in the mounts installed correcty. What year is this 165 and is it a 4 or 6 cylinder engine?
My suggestion is don't mess with it without a manual, and I can give you a link to one if I knew what you really have.

You need manual #3 for a 78 engine. HUGE file 1.3 GB

Manual #4 for the drive, not near as large, only 301 MB

thanks don i will probably just buy those manuals that is way too much to copy. just one question. does the outdrive and engine connect to each other or is there an intermediate connection?[transet plate maybe?] thanks ken

Ayuh,....

The Input shaft of the Outdrive slides into the Coupler splines, which is Bolted to the Flywheel....

Pull the Drive 1st, then the Motor lifts straight Up.....

thanks. so you cant pull the motor forward then up? or would it be just too much of a pain in the @#$ i guess im just afraid to pull the outdrive, hell i dont even know where the bolts are. need to see some good pics i guess.

Re: in line six engine removal

you could pull the motor foward, than straight up if you've got the room. But like Don tells you, you need to re-install the engine first and the drive second.
Look at it this way, the engine and drive need to be aligned when it's all together. And the way its done is to align the engine to the drive, not the drive to the engine. So the drive has to come off either way.

Ayuh,...

The Rear Motor Mounts are designed for the motor to be lifted Straight Up,+ to be set Straight Down......

The Outdrive is only held on by the 6, 5/8" Nuts you see,+ the Trim Rams....
And,.... Reinstallation only requires a Less than $10.00 Gasket Set.....

Download the Manual,+ you'll see what We're talking about....

Ayuh,....

Without doing Awhole Lot of Swapping,+ fitting,...

Another I6, 250 Chevy of the Same Vintage is your Only Choice......

Some pickup truck,+ van motors will Fit, but you have to be Careful,....
Some of them don't have the holes from the front motor mount...

I just rebuilt one for my dad's boat - it's a great engine. Simple, dependable, easy to work on. You definitely want to stay with the inline six.
