    When I set mine up (as I said it is not the 'stock' generator), I gave some extra length on the battery cables and fuel lines to have room to maneuver it if needed (depending on which way I need to spin it ;)). I do need to remove the exhaust hose (2 clamps) and the raw water supply hose (also 2 clamps and closing the sea cock), but they are both fairly accessible and easily done.

    Look at it this way, disconnecting each of them also give you a chance to inspect everything. You can spot a hose starting to go bad. An electrical connection that might be starting to corrode, etc.

    Here are some pictures I took last night of my generator and access to it.

    Also, here is my latest addition:

    When I did my repower, I added two hoses that I had made up by a local shop to the bottom of the oil pans to feed the oil change pump I purchased. The 10 hour oil change was pretty simple. I believe this will make my life easier going forward. Have the open third line to plumb in the generator, when I get around to it (With a generator that only hold 1.13 quarts, how hard is it really to change the oil without it ;)).

    looks great. Wish I had a way (and a place) to pull mine this off season and rehab the engine room.

    Thanks for sharing the pics! Did you look into hooking the pump up to the trans as well? Would love to have a 5way setup to handle everything!

    You’re going to love having that pump.
    My Reverso is connected to both engines and genny.
    I’m going to put drain valves with shut offs on them in my V drives drains this Fall and want to add hoses to them that will be left threaded on the drain valves and have 3/4” male hose on the other end so I can just hook my portable Jabsco pump up to them and drain the V drives.
    The hoses will remain attached to the valves on the V drives, capped and curled up out of the way when not in use.
    Who made up your hoses for you and what kind of hose did they use?

    92 Cockpit Seating.. Has anyone found a better way to move the cockpit seats around, when needing to gain access to the engines? The floor mounted brackets (pic below) can be a pain to lift/slide over - would love to replace with something else. The Port side, specifically the fridge area, doesnt seem to have any plastic slides either. Easy to add, but that would mess up the alignment (height) of the brackets. Has anyone tackled this, or perhaps newer models do it differently?

    Update - The good news is that I was able to get the exhaust flange and the exhaust outlet off of the Generator by reaching over the top of the gen. It was not fun but it worked. I will have to spin it around to get everything re-installed.
    Now the bad news - the pipe nipple that connects the two pieces is completely corroded into both pieces. I worked on it a bunch this weekend but was only able to get about 1/4th of one thread cleaned out. I've been soaking the Exhaust flange in Chem Dip parts cleaner for a couple of days and it is cleaning up nicely but it doesn't seem to be touching the threads. I priced replacement parts and it will cost ~$1300 to get it put back together. I really don't want to spend that on a Generator that is over 20 years old and has about 1500 hours on it.:eek::eek:

    Where did you have that door made where the old TV was?

    Quick Update - I worked on the threads for 2 weeks with no success. I'm going to try and go a different route by having the a 2" piece of pipe welded or brazed between the exhaust flange and the exhaust outlet. I don't see any downside to this, but maybe I'm missing something. The gen is 21 years old with 1500 hours so if this only gets me a few more years i'm fine with that.

    Do you remember who you used to fab the door? I need to replace the long trapezoid shaped access covers on the inside of the radar arch and I think the best way would be to have something milled by a fabricator.

    One of the things on my to-do list is to replace the switches on the instrument panel with some lighted rocker switches. I am constantly having to use a flashlight when I am on the water a night, just to see the switches. Has anyone else done this mod? Any advice?

    I put in all new rocker switches last season along with guages and dash panels. The rockers are backlit but the labels are all integrated into the dash panels. I need to update the "light tape" on the back of my dash panels but I haven't gotten to that point yet. Searayparts.com sells the parts that you need to update the dash lighting.

    Do you have any before and after pics? Did you do the search light controls as well?

    Another on wish list would be an engine monitor system where I could see engine stats in digital form on the monitor. Do they make a system that would work on a 92 EC?

    I don't think I have any good before pics but can definitely get some after. I haven't done the search light...yet. The controls are available but kind of pricey.

    Yes, but...it all depends on your engine package. I have 7.4MPI's and Fox Marine makes a box that talks directly to the ECM for that engine. It converts the engine data to NMEA 2000 and makes it available to NMEA based displays. There are also devices available for non ECM engines that convert analog signals to NMEA 2000. These are really just alternatives to your existing analog gauges since that's the only data available on the non ECM engines. I'm not 100% sure but I think that any of the Fuel injected engine packages are computer controlled while the carb'd engines are not.
