Powerhead rebuild

[lmc1973]

I have a 1989 60HP Johnson outboard. I am tossing around the idea of rebuilding the powerhead myself. I can get a rebuild kit for half the price of a rebuilt powerhead. Has anyone rebuilt one before? What is the best manual for the job?

OMC original manual- after-market isn't very clear for first timers....

Why does it need to be rebuilt?

Re: Powerhead rebuild

Dhadley,<br />It needs to be rebuilt because 2 out of 3 cylinders are scored and it runs bad after it heats up. I have had 2 different dealerships look at it and give me quotes of $4000.00 to repair it. Do you have any suggestions on what I can do to it to make it last a little longer? I just don't feel like spending that kind of money on a 1989 motor.

Re: Powerhead rebuild

Is that it??? 2 cylinders scored? Let me guess -- #2 is the worst and #1 is scored also but somewhat less.<br /><br />4K seems a bit much if the block is boreable and the crank and rods are still good.

Dhadley<br />You got it exactly! Any ideas on what I can do?

Re: Powerhead rebuild

4k is more than a "bit" much.......it's 4 TIMES the value of the eng!!!!<br />lmc1973, are you a capable mechanic??? If so, you can do this on your own with the exception of the block, as far as boring goes. If you were to do this yourself, I see 800.00 being a reasonable range. any dealer that tells you 4k, is trying to sell you an engine. Yours might be worth 1200.00 if running & in good condition, but with the price of newer outboards, you can't replace what you've got. There is new/demo engines listed for 3500-4000.00!!!!!!!

Re: Powerhead rebuild

Imc: It looks like those dealerships are going to buy a rebuilt powerhead from iboats.com and then try to charge you double for it. Iboats ~ $1700 + s/h for rebuilt. For what they ( dealerships ) want you could upgrade in years quite easily.<br /><br />Count your Blessings<br />Not your troubles

Re: Powerhead rebuild

We typicaly would rebuild that powerhead, including re-dressing the powerhead, for less than 1/2 that.<br /><br />There are many threads about that model motor running lean in the mid range. I would almost bet you were on a nice easy cruise and it started to lock up. To avoid a repeat performance we would suggest to richen up the mid range. <br /><br />As always we would further suggest to do all the updates to it as well. Very simple, no big deal.<br /><br />If we can help just let me know -- dhadley50@aol.com<br /><br />Good luck!

Re: Powerhead rebuild

How do I richen up the mid-range and what updates do you mean?

Re: Powerhead rebuild

Pop over to "General Outboard" and look at hookinfinger's thread. Clanton has the updates listed.<br /><br />Good luck!
