    1990 Force outboard lower drive issue question

    So, I got the 6-page manual for the lower unit but unfortunately all the info in it is the same as in the service manuals that I have. They don't even show the driveshaft numbers that I have on the gear box which show driveshaft as 2 and the other as a 4. And no mention on how to find the right...

    1990 Force outboard lower drive issue question

    I have thought of that, and I do have a tool that measures it looks like a torque wrench, and it measures torque forgot why I bought it, must have been for the I/O boat or a car engine rebuild Here it is halfway done So as you can see without the drives both engines measure the same. The LUs are...

    1990 Force outboard lower drive issue question

    I did all that, sprayed it everywhere to no avail. I even switched carbs from one engine to the other. Switched the electronics. The only thing I didn't switch are the LUs. Engine compression 160 on all after rebuilding and break in. I know this should not be a hard issue, but I was perplexed...

    1990 Force outboard lower drive issue question

    I did the trouble shooting and could not come to any conclusions. On a hose in the parking it doesn't do it. It only stalls in the lake. I did spray all around the intake carbs etc. The only thing that I narrowed it down to is the shimming in the drive. I mean it doesn't stall slowly it dies...

    1990 Force outboard lower drive issue question

    Hey guys, I don't know if you read the comments, but do you think that the drive not being shimmed properly after I originally rebuilt it can cause the motor to die in gear at idle? And the water coming out of the nipple to be hotter than the second drive I did not touch? Both motors were...

    1990 Force outboard lower drive issue question

    I know that manual doesn't specify anything on the forward gear shimming from scratch. It only tells you what to do if you have 2 variables. So either you know front gear code and shim measurement and find the housing code in the chart then you substitute for the new housing or front gear etc. I...

    I have no clue where/how to send PM the message to you was denied. Your option for start conversation is not available. I found a listing for FORCE 85-150 HP Lower Unit Outboard Factory Service Manual Boat Marine OB4527 and bought it for 25 bucks shipped. I hope that's the one I need. I asked...

    1990 Force outboard lower drive issue question

    Thanks Race would you happen to know if the gear housing has a code stamped and where it is I cannot find it on either one of my 2 Lower Units for the 1990 Force 120B? Jerry mentioned something above by the tear drop shaped hole next to the drain. I cannot find it. Thanks

    1990 Force outboard lower drive issue question

    I opened the second port side drive completely. So, the 2nd drive has forward gear code 8 on the housing and the shims behind the front gear race measure 0.017. That makes the housing code 9 based on the book chart above. The STBD side housing has front gear code as 7 and the 2 shims I pulled...

    Here are the codes from the top. Is the tear drop the tip right by the shift rod?

    1990 Force outboard lower drive issue question

    I have the tools for shimming, the spacers and the driveshaft, but the forward gear is the one I don't know. So, as I said on the LU there are 2 codes one for the forward gear 7 and one for the driveshaft 4. Where is the code letter or number for the actual casing. I thought it's on the housing...

    1990 Force outboard lower drive issue question

    So there were 2 larger shims behind the forward gear race that measure .018mm each. There were 2 spacers that go on the gear side of the front gear one measured 1.44mm and the other 1.66mm. And on the driveshaft, there were 3 really thin ones. I really don't want to take the other drive apart to...

    1990 Force outboard lower drive issue question

    It doesn't overheat anymore I replaced the impeller and overheating is fine but the temp on the starboard motor is higher than the other one by touch at the water nipple. I took the LU apart today because as I mentioned when I got the boat it had water only in the LU and I decided to open it...

    1990 Force outboard lower drive issue question

    I have twins on my boat initially I rebuild one motor and then noticed the second was full of water and rusted bearings so I replaced the front bearing and gear and the top bearing. I put it back and when I put it in gear at idle it would kill the engine. I took it apart and compared to the...
