    20 amp wire harness fuse keeps blowing

    I have a 1989 80 HP Merc. There is an inline 20 amp fuse in the wire harness on the motor. When I bought the motor, it only had a trim up solenoid. No trim down. So I put in a trim down solenoid and I think I wired everything up correctly, but the 20 amp fuse blows when I hit the trim switch on...

    89 Mercury 80HP lost power to controls??

    Hi all, could use some help here. I have a 1989 80HP Merc that I just picked up. Got it on my boat and everything was working fine, started right up, trim/tilt worked no problem. Shut her down... tried to start her back up again and for no reason, there was no power to the control box. The...

    BIA Standard Bolt Pattern

    Hi all. I am getting rid of a 1989 85 HP Force and replacing it with an 89 80 HP Mercury on my 17' bowrider. I believe most outboards went to the standard bolt pattern in the mid 80's, but I am hearing that the Chrysler Force did not. Does anyone know if that is true? That the bolt pattern of...

    80 HP Merc Oil Injection

    Hi all, I just purchased a 1989 80 HP Merc with oil injection (2 stroke). My previous motor did not have oil injection, therefore I have about 5 or 6 gallons of 50:1 fuel/oil mixture in my gas tank. My question is: Can I use the remaining 50:1 fuel with the oil injected motor without...

    89 Bayliner Capri 1700 deck repair

    Hi all, I plan on tackling my first deck repair this coming spring and was hoping you could all give me some advice. I bought this boat/motor/trailer for $500 and the motor is in good running condition (after some tuning and clean up and the trailer is fine). The boat itself has been neglected...

    Johnson - To Buy or Not to Buy

    Hi all, Could use some friendly advice from some seasoned Johnson owners. I'm looking at a 1976 85HP Johnson for $600. Haven't tested anything yet, but I'm told that it runs perfectly, starts right up, good compression... just came out of the water (salt) this past September and ran all...

    1989 Force 85-No compression in #2 cylinder

    I have a Capri 1700 with a 1989 Force 85 HP. Motor runs, but maxed out at about 27 MPH and would stall at WOT. Did a compression test and cylinder #2 has no compression. Honestly, is it worth fixing? I have a mechanic friend that would help me out and not charge me labor, but I'm thinking this...

    Do I need floatation foam?

    Hi All, I have a 1989 Bayliner Capri 1700 and I am going to be ripping up the old rotted floor and putting in a new one. I am relatively certain that the floatation foam in there now is soaked through and needs to come out. My question is: do I need to replace the floataion foam with new...

    Choke Solenoid - 1989 85HP Force

    I recently replaced the choke solenoid and ignition switch on my boat. They were working great. When I would push I'd here that nice loud healthy "click". Then one day... for no reason at all, I push the key... and nothing. I checked the voltage from the switch, all the way to the solenoid and...

    Is my 1989 Force 85 sitting too low?

    Does anybody know if there was a ?long shaft? 85hp Force? The motor on my 1700 Capri seems to be too low in relation to the hull. I am thinking that this may be contributing to the low top end speed. I have always thought that the cavitation plate should be more or less even with the bottom of...

    1989 Force 85 stalls at full throttle

    Motor idles fine. When I get her out to the bay and hit the throttle the boat planes off great. I don't have a working tac, but using GPS I hit full throttle at roughly 27MPH and then the motor dies. I'm able to start right up again and plane off again, but when I hit full throttle it stalls...

    Outboard Submerged - Help!!

    Hi all...pretty new to this site and could use some help. After a hard rainstorm, I went to check on my boat and found that it went under. The ropes held it from going to the bottom, but the motor did become mostly submerged (the top of the power head was above water). I got the boat out of the...

    Spark Plugs for a 1989 85 Force

    I was recently told by a marine mechanic that I should switch from the Champion UL-18V surface gap plugs to a L77-JC4 plug with a .042 gap. He told me that "This plug fixes a problem with the newer unleaded fuels that the 89 year model engines cannot overcome otherwise. It vastly improves...

    Force manual Tilt

    I have an 85 HP Force with manual tilt. after I bought the boat, I realized that the revrerse lock is broken. The knob on the motor is still there but isn't connected to anything on the other side. It looks like there should be a rod that runs to a metal attachment that locks onto the motor to...

    Timing on a 1989 85 Force???

    Could anyone give me instructions on how to adjust the timing on a 1989 85 Force? I'd really appreciate it. I'm told it should be at 30 degrees BTDC. Thanks any and all for you help.

    1989 85 Force Losing Prime

    My Force won't keep it's prime. I need to inject fuel directly into the cylinders to get it started. Once it's started it idles okay(I have other issues I'm working through but that's another story), but when I try to start it after a day or so, I need to re-inject the cylinders with fuel. I put...
