3.0 harmonic balancer wobbly.

[Ensign Newby]

I was trying to find info on how to change my 3.0 harmonic balancer while in the boat. here is my plan.
1>Use a 7 foot long 4x4 with a eyelet across the gunwall and chains to hold engine hook.
2>unbolt the front engine mount from the bottom of the fiber glass and remove from engine.
3>rent puller and installer from autozone (and buy replacement)
I do not have a center bolt but I see bolt threads on the pulley.
Can anyone please comment on my plan. Will I mess it up unbolting the mount's?
Is it safe to run at all?
Thanks in advance.

Why would you want to do that? Do you have the manual?

Thanks for the replies. I looked into an engine hoist for 30 a day but not sure it would reach. wondering if the gun walls are strong enough. Not a fiberglass guy! lost an outdrive last week and replaced it with a beauty merc repower and noticed when the engine jerked around the motion transfers through the shaft. I imagine this movement is what fried my old SEI drive or at least contributed to it.

What no trees in your backyard with strong branches for a nylon sling, & comealong or chain hoist?

Sadly..no. No descent hangin trees. As I ponder what to do if notice there are no 3.0 auto equals out there. So looks like the ol sit and wait AND the $300 price tag. Checked compression for some reason 135 to 145 psi variance.Started her up on muffs and as it hits 1600 +rpm There is a noticeable rattle that seems to come from around the area. wonder how to test mounts. Still that darn wobble. Second pot of coffee. Anything else I need to do while I have it apart???

Everything worked great. The part got here today.. The 4x4 with a hook screw worked. Even able to raise it up to align the mounts by adjusting the nut I used the wood installer tool option.But I found the alternator bracket was another casualty of wobble. Still able to test it on muffs, No more wobble.
Happy boating!
