Pulling powerhead

[Rayson1971]

I have an 87 200 BM and pulling the powerhead. Hasn't been off for a long long time. Seams to be frozen on. Any ideas? Rosebud torch?

Triple check you got ALL of the nuts off...
I have had good luck with a bit of time, penetrating oil, vibration and heat.

Spin 2-3 nuts back onto the threads, but not tight. Use your hoist to put tension on everything. Not picking the whole boat up, but enough to know the load on the studs is going up instead of gravity. Lots of penetrsting oil.let it sit overnight. That will get freshwater motors free most of the time.

An air hammer vibrates the studs and help break the corrosion free too. Using heat, i do a small tip, and just heat the stud, then spray with penetrating oil for a nice smokescreen. The heat pulls the oil up the stud nicely.

Lather, rinse and repeat as needed.

Looks like you missed 2. One on each side.

Where. I pulled every one i could see. The 2 in front the powerhead needs to be loose to get the nuts off. I loosened 5 on each side.

There are 3 or 4 seams there. I suggest working your way down from the top seam first. I believe there are 1 or 2 nuts/bolts inside that isnt accessible until the layer above is removed. I am going off 15 year old memory though.

There is ten nuts total. The front two and the back four you can get a pry bar under and help it along

Got the powerhead off. I have a lower unit shaft cut and mounted on a cart. Will it be ok to drop the powerhead on the shaft start disassembly. Or is there a better way to mount ?

Rolling engine stand,just find the right bolts. Then you can spin it to disassemble it.
