I have an 85 force 50hp it runs great, its simple to work 1 carb 2 cylinders not much really to it , I havnt done what you have though I think it would scare me to tear everything apart, I dont know if mine has that type bearings in it or not prolly so I would end losing one for sure, I think it will run fine when your done you did a pretty job myself ,cool video stay safe and god bless
gotta say, I have a 1989 85hp force and it really has a bad reputation. After I did a fresh rebuild on it with forged pistons its been as reliable as can be. I even trusted it enough to take it on lake superior. some people swear by these motors and having one for 3 years I can say I do too!
Im planning on rebuilding this one top to bottom, just wanna take my time and do it right. The force outboard owners group on facebook has been a wealth of information. After its rebuilt I think it's going to be a solid motor! Glad to hear yours is treating you well!
@@NorthwoodsNoise absolutely! That group is awesome, chuck is very knowledgeable. Also, a good recommendation for parts is TSM performance. They have rebuild kits for a good price in case you have trouble finding parts. Its definitely a good option
From what I read when I looked into it the Pittsburgh gauges have two different styles of check valves. One works well, one doesnt. Apparently I have the one that doesnt. Mine is off by about 20% compared to a good snapon gauge I borrowed. Off by the same 20% on two strokes and 4 strokes.
use a ball hone and pay attention to how many strokes you take. Chances are you will need to tear down the rest of the engine and get a .020 or .030 piston and have a machine shop bore it out. WIth an outboard you need only oversize the bad hole, the otehr pistons can remain standard. It is not like a car. But if you have to hone more than say 18 to 22 strokes you have already oversized that hole and it will no longer be round. Doesn't cost much more to bore one cylinder and you can then see the others and how they really are. Force outboards were not the greatest for top speed but they were fantastic at low end torque. my experience? 54 years as marine mechanic and repair shops nation wide. (retired this year)
Hi Northwoods, I have a 1963 Evinrude 10 hp that I'm replacing the powerhead on one that I got from Ebay, will I get good results if I check compression if powerhead is not mounted?
That's not a bad way to do it. Most all transoms on smaller older boats like this will have a degree of flex to them. How much flex you're comfortable with is up to you in the end. If it seems like too much flex, odds are it is.
@@sammyrothrock6981 Greater fine motor control with a file. Too many rpm with a wheel. Gouging. Wheel catching soft aluminum sending the piston across the shop. The list goes on. You could argue over course/fine, but a file would always be my tool of choice in this situation. Rough isnt necessarily bad as the grooves will hold lubricant but I'd rather there be a pattern to it over the haphazard scratching/gouging of a wire wheel.
@@NorthwoodsNoise there are many different wire wheels from corse to fine. I was a small engine John Deere mechanic have 50 years experience . Your entitled to your opinion but, I been around a long time
@@sammyrothrock6981 my opinion is that anything besides boring the block and replacing the piston is a bandaid, so I dont think it really matters. File, wire wheel, bead blasting, whatever. You still have an undersized out of shape piston in an oversized out of round bore. More about the skill of the individual doing the work than the tools used in this scenario.

The Force will only bring you tears
Liking your videos…keep up the great work!
Thank you! Glad you're enjoying them!
Those harbour freight gauges work good with 4 strokes. I don't know why they don't work right with 2 strokes.

The same thing happened to me this past weekend. I bought without checking first

question: guy has a 70 yam 110 on 1 and 3 cylinder and 75 on 2 how can you tell what it might need? ty
Hi Northwoods, I have a 1963 Evinrude 10 hp that I'm replacing the powerhead on one that I got from Ebay, will I get good results if I check compression if powerhead is not mounted?
When you ran that hone, grit would've gone into the transfer ports....maybe plugging them up would have helped
Wow a Force with an issue. That's new.......
🤣🤣🤣
can you tell me more how you cked the transom? I was told to raise the motor and lift on the foot and see if the transom flexes? ???
That's not a bad way to do it. Most all transoms on smaller older boats like this will have a degree of flex to them. How much flex you're comfortable with is up to you in the end. If it seems like too much flex, odds are it is.
Why didn't you take a wire wheel to the piston skirt instead of a corse file? That's pretty rough

@@NorthwoodsNoise then I use some 1000 grit sandpaper
@@NorthwoodsNoise bead blasting is one of the better options but, never a file

Where can a guy find force outboard parts?
do you have a follow up vid
Yes, there's a few more videos on the boat in general. Ended up repowering with a four stroke yamaha.
Does it run
Yea it ran like this, just wouldnt idle well and had no power.
Delt with many Force motors.They didn't camfer the ports from factory.
Short cut king!
trailer light out.
Don't reuse the piston
A ball hone would have made quicker work out of this.
Detonation lol
