Hey SKIDIM Fans!
We made a short video for your education called Engine Alignment 101.
Use a Feeler Gauge to get the required spec of .003 or 3,000ths or less a full 360 degrees around the transmission coupling and the shaft coupling
BEFORE you bolt these flanges together! Watch our very own, legendary Vince Dougherty explain in this 3 minute video to keep your boat from vibration.
Then, check out our engine mounts, shaft seals, strut bearings and all your drivetrain needs at www.skidim.com.
Thanks for watching and leave your comments below!

How does the process change on v drives?

Oh boy, engine alignment...the stuff nightmares are made of...

And presumably re-tighten the 2 aft trunnion locks ? Are there forward trunnion locks ?

El que no este bien alineado el eje de la cola intraborda con el bloque motor puede producir tanto vibraciones como mala respuesta del motor?

Thank you for this informative video. I have been studying the engine mounts on my Hino Marine diesels and while I do have the vertical adjustments I do not seem to have a system like yours for horizontal adjustment. I am trying to figure out how one addresses this with my setup. I wonder if perhaps the holes for the vertical mounting bolts are slotted or just a little over-sized as an alternative to allow for lateral movement. Have you ever encountered this situation?

@rogerlloyd9413 7 месяцев назад

Another video shows a slotted hole.

It looked like you were moving the right side of the engine forward with the pry bar? Even though that side was the side with the larger gap. Am I misunderstanding how the engine moves on the mounts? Thank you for this helpful video! Planning to adjust my v drive boat.

The simple rule is: if you have space on the left the engine must slide to the right and vice versa. The shaft is kept still and the engine must align up, down, left or right.

Now how great is the change that the engine and shaft are out of alinement axial? That should be checked before mounting the bolts again. I would have moved the engine on the front side to keep the axial alinement ok

Should the feeler Guage not fit in anywhere? You explained that there should be an equal distance all the way around but that could occured because the shaft is moving back away from the motor. Also shouldn't this be done in the water because the hull flexes.

The best way to check it is with the boat in the water with the 2 couplers unbolted but the 2 faces flat against each other. You are allowed up to .003 gap or less. if the 2 faces are tight against each other your perfectly aligned.
