HELP: removing upper mount 90 hp ocean pro ...secrets???

[bob johnson]

changed up the title a little

I took my power head off tonight...what a pain...200 lbs of torque for 2-3 " of screw X 6!!!!


yuk


thank the lord for a cheap electric impact gun.


now onto the current proble,

under the power head ther is a dual rubber mount...that the steering arm base had been attached to...

this mount seems to have been held onto the power head, by one long bolt through the middle.

well i took it out and the mounts dont seem to want to move...


they look like steel encased rubber, because the out layer seems to be crumbling..( steel part)

it is such a corroded mess under the power head..it is hard to figure what is what at this point

so i am asking for a tip to pull that rubber mount off...


I am taking the power head to work to machine off the lower crank housing bolts...whose heads have rusted into oblivion..

a note to all you who think it is easy to rebuild a motor....

if it has ben in salt water use...you are in for a series of head aches


I broke two of the small power head bolts..

but the corrosion( on seemingly a nice looking motor) is a big obstacle to the do it yourselfers!!!

I needed a torch to take the big power head bolts out!!


thanks

i dont have an ocean pro but mounts are mounts usually.. if you have the powerhead off it should be all there for you to see..

my upper mounts had 2 bolts connected to the Y bar and then 4 bolts holding down the mounting plate... once those are off you shoud have all the access you need. the mounts are in there pretty tight...i had to cut mine out due to corrosion ..with a sawzall.. not the metal but the rubber to get some play..

well there appears to be some corrosion under there, and i dont want to guess what is aluminum power head and what isnt...

two big dia bolts held the power head to the steering pivot....but it looks like only one bolt was holding this mount to the power head...

from the expolded diagram there MIGHT be a second smaller bolt coming in from inside..but i didnt see it last night...

I could'nt get the mount to budge a small bit...so i am thinking it is attached in a way I am not considering...so i stopped and am seeking advice..

and the almighty factory manual has NOTHING on the upper mount..other than the torque spec for the bolts going throuigh the steering arm into the mounts.....

they show the dissasembly of the power head with no mention of taking the mount off...

Re: HELP: removing upper mount 90 hp ocean pro ...secrets???

The hole where the long bolt went through the mount assembly is a tapered piece that wedges the mounts against the sides of the block. Usually you can instert the end of a long tapered pry bar and wiggle the tapered piece free and remove it, then remove the mount assemblies.

It would be best if you had a factory service manual to refer to.
