I have a 1997 Force 120 that I bought last year from someone that thought it was blown. After taking apart carbs and reed blocks I found that the reeds were worn down real bad. I changed the reed blocks and it has been running fine for about eight months now. When i got it in April 2010 I did a compression check and the #1, 3, and 4 cylinders were about 130 to 135. The #2 was about 110 but I decided to run it anyway and have not had problems with it yet. I would like to garantee that I could get a couple more years out of it until I decide to buy a new rig. Does anyone have an opinion about breaking it down and changing all the rings and gaskets as long as the cylinder walls are not scarred. I have rebuilt alot of outboards in my life for myself and family so I know what to do any look for, just need someone elses opinion about the subject...

Re: Rebuild or leave alone

I recomend leaving it alone. You may want to check you carb on the week cylander to make sure it is not too lean. You may have a lot of years before compression goes below 100 which is where I would say rebuild. Why open up a possible can of worms? Make sure to use a good quality oil and it may go for many years to come. Good luck.

Re: Rebuild or leave alone

If you have low comp on one, there is a reason for it.Something is going BAD!!!
Myself,I'd try a de-carb and then pull the head gasket if that doesn't help to check why.
You might be able to bring it back up and prevent any further damage.
$50 now might save U a $2000 later.
If you have carbon build up.It doesn't go away by itself.It only gets worse.
Unless you plan on re-powering,then just let it go.J
