    Wrong shift cable maybe?

    Hey gang, I have a problem with my shift cable on my boat. This is the shift cable that was on the boat when I got it, and I have never actually gotten the boat on the water. The boat is a 1970 Larson with a Mercruiser 120 I/0 with what I assume is an MC-1 drive. However, it appears as...

    Bench testing a trim pump

    Hey guys, I just got an old trim pump for free, one of the square bodied pumps. Before I go through the hassle of installing it, has anyone tested these out of the boat before? I am assuming there is a way to run it across a 12V battery and check and see if oil squirts out of one hole for one...

    Mercruiser nomenclature/which shift cable to buy

    Hey gang, Yet another newbie question. Soon I will be replacing my shift cable. I have a 1970 Larson with a Mercruiser 120 I/0. I am still getting to know Mercruiser names and generations - I am assuming what I have is pre-Alpha, but several of the shift cable kits I have come across list...

    Daily Driver AC advice needed.

    Hey gang, I'm replacing the AC compressor in my 99 Chevy S10 this weekend because the old one started making a lot of noise and quit. (Back in 2004) The system also has no freon in it now; on the back of the compressor where the lines attach it is very evident that there was a large leak...

    Guess my weight and get a free keychain!

    While supplies last. I've got a 1970 Laron 185 with a 4 cyl Mercruiser I/O sitting on a single axle trailer. Anyone have a rough approximation of what that rig weighs? I am considering getting a new truck, but I don't want to have to drive around constantly in a big V8 truck if I don't have...

    Where are the check valves in a trim/tilt system?

    Hey guys, I'm still messing with my stupid trim/tilt system! I did some messing with it this weekend and I found that using my one good trim cylinder, I can extend the piston out, but I can't bring it back in. This same thing occurs on both sides. The trim pump does run when you put press...

    Trim pump oil?

    I'm posting this to clear up some confusion created by a coworker. I have a 1970 Larson 185 with a Mercruiser 120 I/O. It has that square body trim/tilt pump, but honestly I don't know much more about it. On the pump it says to use only 20W oil in the system. My coworker says you can use...

    Should this move?

    Hey everyone, Tomorrow I am going to go look at a set of trim cylinders for my boat. Should I be able to move the cylinder with my own strength, when the cylinders aren't hooked up to a boat or the hoses? (I'm an adult male of average size and stength, haha.) The trim cylinders I currently...

    Estimating trailer weight

    On the advice of a fellow board member, I am going to register my trailer as home made. I spoke with the DMV who stated I need to give the empty trailer weight. I think I can probably get by with an estimate, since my boat isn't running it would be difficult to drop the boat off in the water...

    Shoreline trailer VIN location

    Hey everyone, I'm in the process of getting my boat/trailer registered. The boat went fine, but the DMV said that they need the trailer VIN number. I can't find it on the trailer, and I am not sure where should be looking for it. I don't know what year the trailer is, just that it is a...

    Trim cylinder diagnosis

    I have a question. I recently took the trim cylinders off my boat since the tilt/trim was not working. I was able move one trim cylinder by hand, (and squirted oil all over my car) but not the other. My question is, should you be able to move these by hand with them completely disconnected...

    I can't go backwards!

    Hello everyone, I'm working on a 1970 Larson I/0 with a 120 Mercruiser. I believe it is GM 4 cylinder engine, I am not 100% sure what the outdrive is as there are no markings to speak of and the number stamped on it is no longer legible. The outdrive is currently removed for another problem I...

    Dropped a boat on a bridge....

    This is my own stupid human trick, it happened during 4th of July weekend in 2000. I was 21 years old at the time. I had just bought myself a nice Chevy Silverado, and I got a good deal on a 25 foot Century CC. The deal was, I got the boat super cheap, but the seller wanted to keep his...

    Engine won't turn over

    Hello everyone, Sorry my first post has to be a tech question. I just got my first boat, a 1970 Larson 185, with a Mercruiser 4 cylinder I/O. It supposedly ran, according to the guy I bought it from, a month before I got it. I know I should have asked him to run it for me, but since I got...
