    Hard shifting after new lower cable....sometimes

    After I replaced mine it was binding pretty bad. What I discovered was that I skipped a step when installing it and did not back off the set screw a 1/4 to 1/2 of a turn to allow for the cable to rotate within the assembly without trying to rotate the arm as well. Also binding may be an issue...

    help identify engine

    Based off Mercuriser's parts database here: https://www.mercurymarine.com/en/us/parts-and-accessories/parts-catalog That serial number matches in the range of a 150 Inline 6 not 165 Inline 6. I may be wrong but it shows serial numbers 1666495-2048046 as 150 GM 230 I/L6. The years are between...

    What is this and where does it mount?

    ok so if I understand what you are saying correctly, what I need to do is order that pump, replace the one hydraulic line (I'm assuming this is the one that connects to the reverse lock) and then plug the new pump in, mount it in the boat, and fill it with oil? How burried is the line from the...

    What is this and where does it mount?

    Do you happen to have a parts list of what you bought or a link to a thread that details the change? Also what wiring alterations did you need to make for the new pump and was it all done at the pump or did you need to run new wire up to the helm as well?

    What is this and where does it mount?

    How can you tell (serious question not being sarcastic)? The description reads High Pressure Low Volume, but I understand Amazon descriptions are not always correct. I cannot find a Sierra Marine website but I think they make fairly ok parts? Maybe? I just don't know how to get more information...

    What is this and where does it mount?

    From what I have found I think this: https://www.amazon.com/Sierra-18-6768-Compete-Assembly-Mercruiser/dp/B002IV6RXS may be a modern replacement. It appears to have female fittings coming out of the base of the pump but I'm right by a Tompkins and can always either pull those fittings out and...

    What is this and where does it mount?

    Also is there a place where I can purchase that shift plate lever and change out the current one, or do I just have to upgrade the trim pump to one with the reverse lock valve integrated into it?

    What is this and where does it mount?

    If I shift the unit into revers out of water and try to pull out on the cylinders to see if they move will that be adequate or does it need more load? Also, I would bet that I just called the wrong drive out and that I actually have an MC-1. The sticker is worn off the outdrive so I made...

    What is this and where does it mount?

    Sorry for the delay weather and my schedule got in the way of me being able to get pictures. So back on topic. I have attached pictures of the shift plate as well as the trim pump. Is this a Prestolite or Oildyne system? If it is a Prestolite does anyone see any obvious mounting location that...

    What is this and where does it mount?

    I'll take pictures of the shift plate and pump when I get home. I do not know if the outdrive lifts when in reverse because I haven't gotten it in the water yet and I want to have my i's dotted and t's crossed as much as possible before load testing the boat.

    Out of water running

    It appears to be original with the boat. So maybe an MC-1. From what I can find it is referenced as a prealpha or alpha 1 gen 1. I don't know the exact history of the drives or all of the jargon yet.

    What is this and where does it mount?

    I doubt that it has the newer oildyne trim pump in it as everything looks to be original, but I will check just in case (because let's be honest if the pump was replaced in 1990 with the new style it would be over 30 years old at this point so would look older anyway). If it has the older...

    What is this and where does it mount?

    Ok I need some additional help with this (or maybe just another hint). I scoured the books that I have the internet, this forum and still cannot seem to find how to mount this to the shift plate.

    Out of water running

    In further fiddling I pulled the out drive back off and found out that I forgot to back out the retaining screw on the shift lever coming out of the bell housing. I backed it off a half turn as instructed in the installation instructions. The drive now goes into forward gear no problem and does...

    Out of water running

    Ok doing some more reading I understand that the switch should only engage when going into neutral and under load. the issue I have is that the switch activates when trying to go from neutral into forward and from neutral into reverse out of water. I just replaced the shift cable and followed...

    Out of water running

    It has a brand new lower shift cable. The boat came with the outdrive and bellows off, but it had a new shift cable assembly and I installed it when I reassembled the outdrive. This is why I am confused because the manual has details on how to trim the shift cable, but the directions in the kit...

    What is this and where does it mount?

    Ok thanks. I'll go see what I can find in the book on how to install it. I had no idea what it was so didn't know where to start.

    Out of water running

    I don't follow your meaning. It looks like the shift interrupter won't go back to the middle position so it would just kill the engine entirely. Is there something I am missing?

    What is this and where does it mount?

    So while attempting to adjust my shift linkage I found this zip tied onto the exhaust. It appears to be part of the trim or tilt system. Does anyone know where this mounts so I can get it properly installed? Motor is a 76-79 Ford 351W. Thanks for any help.
