    Hooray

    I work too much. I finally got to run the boat today, no incident. I'm on my 2nd year of ownership with my Baja. Last year I bought the boat from a guy who buys & sells recreational vehicles such as boats, 4 wheelers etc. He said he did all the maintenance but I had to redo things to be...

    88 5.7 Mercruiser Spark plug change

    I am in my 2nd year with this boat and hadn't changed my plugs yet. So I got up early today and went out to the yard thinking I'd pull a plug & look at them. I had bought a set of plugs but I was going to see how the old ones looked first. To my surprise I could not get a plug socket on the 3...

    Can't hang my Alpha 1

    I had my bell housing off for a new shift shaft bushing & seal. Now I'm ready to reinstall my drive. It's an Alpha 1 gen 1. Same recently replaced gimbal bearing etc. I greased my drive spline, checked alignment with a proper tool and went to slide it on, but the darn thing misses every...

    Pitch change

    I am just getting my boat's state of tune optimized and it looks like I need another inch or 2 of pitch. Is there any chance a prop shop can add cup or pitch to a banged up aluminum 3 blade 19" pitch Michigan Wheel prop? I know, ask. But is it even worth my breath to ask?

    drive squeak

    I chickened out on installing my new u-joints and took my drive to a car & truck drivetrain shop to have them installed. I'm now a little concerned that it may have been a bad choice. When I turn the drive shaft at the yoke I hear a rubber squeak like a dry seal. I turned the same piece...

    front motor mount adjustment

    I have put in a new gimbal bearing etc and am starting to align my engine. For the life of me I don't see a logical way to adjust my front mount height. The mounts have a large threaded rod vertically through them with a 1 1/16 nut and washer on top. There appears to be height adjustment...

    Did I fudge up my drive?

    Got the ol' boat cleaned up & launched for the first run today and heard a bearing noise while in forward & reverse or while trimmed up so I limped her back to the trailer & came home. I did some reading and figured I will just do the u-joints and gimbal bearing while I have it open. Stop me if...

    3M 5200 cure time

    I used some Fast Cure 5200 yesterday for my transponder mount holes. The holes had been drilled too low by my boats previous owner. So I drilled oversize new holes about double the size needed, redrilled the bad holes to the same diameter, and filled all 4 with the 5200. The temperature went...

    Weird Gauges, Ghost In The Machine

    Hey, not that every weird gauge issue will yield the same result. But here is what happened to mine. My boat is an 89 Baja Sunsport 196, it is powered by a 5.7 litre Mercruiser with Alpha 1 sterndrive. When I went to un-winterize this spring I found that when I turned on any electric dash...

    What are these things?

    Sorry, no picture, but here is my question. I have been under the dash of my boat this afternoon trying to chase down what I believe to be a ground fault. When I turn on the navigation lights I only get bow light, and when I turn on my anchor light it does come on. Plus, and this is the...

    resistance wire

    What is the function of the resistance wire in the ignition system of my Mercruiser? I assume it fuses some function. Do resistance wires wear, or get tired?

    Lowrance Skimmer-How fast can it run?

    I bought the boat in my signature last year. The first time I really let it run to speed the skimmer transducer on my transom broke right off the boat. Now I want to confess that I haven't owned one of these before so I may have set the pivot tension incorrectly. May have set it too tight. I...

    gauge issue

    I installed a new fuel hose today and got my motor un winterized. 89 5.7 Mercruiser , Alpha 1. But I have somehow created another issue. When I was running on the muffs my temp gauge did not move and my fuel gauge showed empty with a 3/4 full tank, I was able to see 150 degrees with an...

    stupid, stupid, stupid

    89 5.7 Mercruiser. Well, I went to pull out the boat from winter storage and did a dumb thing. I had bought a new coil because the old one looked cracked. I cranked it with the new coil, no start. Then without checking I put coil leads on in reverse because the new coil was in the other way...

    Shutter Identification

    I have a 1989 260 horse 5.7 Mercruiser with normal exhaust. The pipes exit the risers make a downward turn and go into a Y shaped collector before exiting the transom. My shutters are at the top of the Y. I am trying to get a positive ID on the shutters because they jingle and I am replacing...

    Ratios

    So if my drive has a ratio of 1.47 is my prop turning 1.47 times engine RPMS? Or am I turning 1.47 divided by engine RPMs. And for example, I saw a video of a guy with a built Evinrude 200. Is his prop turning the same RPM as the engine? Or do they have a drive ratio involved?

    ignition parts

    I'm looking for opinions on ignition stuff for my 89 Mercruiser 5.7 Litre, 260 HP, Type MCM. It has the Thunderbolt Ignition and it does pretty well considering. Considering the rotor tip is burned, the rotor connection points on the cap are corroded, and here is the biggie, the coil is...
