    Problem installing new prop shaft

    I have a 1996 90tlru outboard I just bought recently. Found that the prop shaft was a little bent. Eventually got the old one out. Replaced the reverse bearings and kept everything else the same. Did my best to follow manual and diagram to put everything back together. Dog clutch sits in neutral...

    Lower unit not bolting up...not the commons problems

    I have a pre-alpha outdrive that had an alpha 1 lower unit. I replaced the yoke end seal because I was getting gear oil in the bellows. I then changed the lower unit to a pre-alpha because the lower unit had a big crack in it. The lower unit I am using now has the pre load pin which shouldn't...

    Mercruiser 4.3 Stalls when shifting after outdrive removal

    I have a 1990 boat with a mercruiser 4.3. I replaced the engine coupler because it stripped out. When I removed the outdrive I put the boat in forward and now that I have put it all back together it is difficult to shift and stalls when I go into forward or reverse. Is is likely that the...

    Mercruiser 4.3 Set idle or timing first

    I have a 1989 Mercruiser 4.3 with a thunderbolt IV ignition. I have a misfire at high rpm's (4200-4800). I checked out the fuel system and believe that it is fine. I replaced spark plugs, wires, cap, and rotor. The compression is good. The boat is idling at 900-1100 rpm's. I decided to...

    I have a 90 wellcraft 170 classic with a mercruiser 140. I know that there are different types of ignition systems but am not sure which I have. My engine does not actually have a distributor cap. I has a thing that adjusts like a distributor and has a coil giving power to the spark plugs...

    I have a 1972 Johnson 60hp that is not getting any electric to the engine. The battery is good and I have power at the front end of the starter solenoid but the electric choke has no power and I don't even get any power to the lights on the boat. Is there a fuse or something inside of the...

    Vibration - I'm out of ideas. Please help

    I have a 1979 Renken with a 140 mercruiser. I have a bad vibration that shakes the whole boat. The vibration is with and without the outdrive on the boat. So it doesn't seem related to alignment in any way. I also changed out the engine coupler because it seemed warped (I would align the...

    Please help me track down vibration

    I have a 1979 mercruiser 140 which has a bad vibration. Almost a thumping. I changed the gimbal bearing and the u-joints seem fine. I used the alignment tool. The vibration is still there. So I took off the outdrive and still feel it. It looks like there could be cracks in the coupler and...

    1977 Johnson 35 Carb Rebuld Problem

    My dad has a 1977 Johnson 35. The boat would not run well unless the choke was out. After reading posts on here we decided the carb needed to be rebuilt. I did so and the motor is running better, but still having the same problem. As soon as we put the choke in the engine wants to slow and...
