i am mating new Bravo 3 stern drive and gimbal housing to a Yanmar
4LHA-STZE Diesel in my 26' Bertram
I do have an alignment tool.:)
What is the proper order of the various spacers and washers that comprise the rear engine mounts? and what is the best way to remove the old rubber bushes?:confused:
Any hints on the alignment procedure?

Thanks...very helpful.

I removed the old flex bearings which had been put in upside down. There were no fiber nor double helical washers. The mounts were metal to metal.

Previous owner had destroyed 2 outdrives, I'm convinced this was due to misalignment.

The new bearing Yanmar P/N 119778-08310 "Mounting flexible" kit has identical flex bush as Merc. fiber and SS washer, also a large SS washer with a tapered inside, I assume this washer fits in the inside of the engine mount with the taper facing up?

I believe that when the alignment tool is correct it can be freely rotated without any binding.

Click to expand...

Ayuh,... Aligning is more of a push/ pull motion, rather than twisting....

Slather the tool with Grease,... Insert it, push it home,... Withdraw it,+ inspect the spline Tracks in the grease...
They should be even all the way around the tool...
Rotate the motor, 90?, repeat, 180?, repeat, etc...

Good Luck... 'n Welcome Aboard...
