    1990 Force outboard lower drive issue question

    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...

    The shims behind the front gear are actually 0.18 each I think

    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...

    1990 Dual Force 120s one side showing 16.7v at speed with dual batteries

    The only option to combine is under the warning yellow. I know it separates the house and start bats. It was wired per web site instructions. I know this has a system that enables and disables the relay based on the voltage. It also puts the 2 batteries in parallel under certain conditions. If...

    1990 Dual Force 120s one side showing 16.7v at speed with dual batteries

    Hey guys sorry for being MIA on this. So today I went ahead and changed the switches on both sides. I now have the BlueSea 7650 on/off with ACR. I pretty much rewired the area. I will show pics. I briefly started the motors afterwards and one shows 13.5 or 14 at idle that's the starboard while...

    1990 Dual Force 120s one side showing 16.7v at speed with dual batteries

    The spot it goes on is right by the starter on the port side. I will test the temp with a laser tester when I take it on water again hopefully this weekend.

    1990 Dual Force 120s one side showing 16.7v at speed with dual batteries

    I included some pictures on the previous page but it is mounted the same way as yours. Except it is with the epoxy towards the motor. The heat paste is a good idea I thought of that aswell. I am sure my main problem was with the batteries even though only starboard motor showed overcharging.

    1990 Dual Force 120s one side showing 16.7v at speed with dual batteries

    I got to look for some pc procesor fan heat sink maybe with the fan attached to cool it. Imagine? I think it needs 5v not 12 could be wrong

    1990 Dual Force 120s one side showing 16.7v at speed with dual batteries

    Can you give me a part number for reference and is it the 4 or 5 connectors? Also I assume that this won't handle the deep cycle batyeries either. The ones I looked at on eBay have one positive conector and one stator plus ground and ignition. How do you connect the 2 stator and tach. Tach can...
