    Outdrive rebuild questions.

    Hello everyone. In an earlier post I asked about a replacement upper half for my Alpha one outdrive for a 3.0. I've seen this posted before, but I need to ask to make sure. So when my upper end rounded the gears, I'm sure garbage got into the lower half as well. Now my lower end has never...

    Mercruiser Alpha One Gen 1 Outdrive questions.

    Hello everyone. I have a question. My boat has an 87 3.0L Mercruiser with alpha one outdrive. Gen 1. This last summer the gears in the upper unit went bad. I puled it apart and cleaned out the upper case, and had the lower case rebuilt, by my local shop. I noticed some dings in the upper...

    Engine just quit.

    Hello everyone. So today we were out on the lake, and the wife and I were doing a run at about 32 mph. All of a sudden the motor just stopped. Kind of thought it locked up at first. Once it stopped, I tried to restart, and it turned over very slow, but then started. Ran fine. Put it in...

    Which way is easier

    Hello everyone. I'm going to be replacing my bellows again on my alpha 1 drive. Last time I did it, it was rather a pain. I'm just curious to know which way everyone replaces their bellows. Do you put them on the transom plate first, or the bell housing first. I believe the last time I...

    Exhaust shutters 3.0L Mercruiser

    Hello Everyone. Just going through all the maintenance stuff, and since I have to replace the gimbal bearing and bellows, I decided to check the exhaust shutter. Low and behold, it's gone. Just the rod where it used to be. So..... 1. Did this hurt anything when it burnt up? And what...

    Alpha 1 drive bellows replacement.

    I'm replacing the bellows on my 87 alpha 1 drive. I noticed in the kit there is a rubber ring that's about 5 inch in diameter. Where does this go? I remember someone talking about it before, but I can't remember where. Thanks in advance. Pat

    1987 Mercruiser Alpha 1 outdrive questions.

    Hello Everyone. I have an alpha 1 sterndrive with Serial 0B575167. I have a couple of questions. 1, how long is the normal life span of the gimbal bearing, and the bellows? I replaced them early 2014, and recently I heard a grinding, which I thought might be the ujoints. When I pulled the...

    Trim issues

    Hello. I have an 87 Arrow Glass 18 foot fiberglass boat with a 3.0L mercruiser and Alpha 1 outdrive. I'm not sure if this is normal or not, but when I take off and I'm going under 6 MPH, the front end is WAY up in the air. I mean not like vertical but to the point where I have to stand to...

    Something weird going on with my 3.0 merc

    Hello everyone. And to start off this post, I'd like to say happy fathers day to all the dads out there. So. I've had my boat out quite a few times lately. Tuesday we took it out and did some tubing with it, and spent a lot of time on and off at WOT, and it NEVER even came close to...

    Mercruiser 3.0 carb adjustments

    Hello everyone. I don't know the numbers for my motor off the top of my head. But hopefully these questions are generic enough that I can get some input without the numbers. I have a 3.0L mercruiser that I rebuilt in my 87 arrow glass boat. This year I rebuilt the carb, and added electronic...

    Evinrude 4.5 pull start

    Hello. I have a 1980 Evinrude 4.5 outboard motor Model E5RHCSS Serial E0001388. This motor is like BRAND new. However, one thing I noticed is that when I pull the cord to start it, the cord doesn't pull back all the way. I have to help it. Almost like the spring has weakened. I took it...

    Evinrude 4.5 HP Question

    Hello. I have a 1980 Evinrude 4.5 outboard motor Model E5RHCSS Serial E0001388. I installed a home made troll master onto this for use as my kicker motor. The troll master works great, but I'm really confused. The hand tiller is disconnected inside, so the throttle should not work. AT LEAST...

    Ignition Coil Mercruiser 3.0 L

    Hello everyone. Not sure if this should go here or under the electrical forum. Figured here since it's engine related. So my boat was running at the end of the season, and I parked it over the winter. Now I have it out of storage, and was going to fire it up for the first time to set the...

    Dual Battery

    Now that I'm going to be spending a lot more time on Lake Michigan, I decided I wanted to run a 2nd battery in my boat. I have a 4.5hp kicker motor, that will be used for trolling, while the main engine is shut down. I ordered a blue sea battery switch, and 25 feet of 3/0 battery cable. The...

    Oil Leak

    Hello Everyone. I have a problem here that I caused, and can't figure out how to fix. I didn't realize that when I changed the oil on my mercruiser 3.0 that I should have used a pump to pull the oil out of the dipstick. So I had a heck of a time getting the drain plug out of the oil pan and...

    Looking for some input on a new graph.

    Hello everyone. I'm looking to replace my old hummingbird 565 grayscale graph. I have two in mind right now. I know there are others out there, but these are the two that I'm interested in. I just want to see what everyone out there thinks. The first that I've been looking at is the...

    Carb Kit Question

    Hello everyone. I am rebuilding my carb over the winter for my 3.0l mercruiser. On the carb there is a green tag with the number 1389-9562 on it. When I went to Sierra's website and looked at their online catalog, it says that the carb kit is Sierra part # 18-7098-1. I found that part number...

    Not sure I understand this...

    I have been thinking about something lately, and I want to know what other people think. My boat is a 1987 Arrow Glass Carisma 175. IT has the 3.0L Mercruiser with Alpha One outdrive. When the boat was new, it had the mechanical fuel pump with filter built in, and was plumbed with solid...

    Is this correct?

    Hello everyone. I'm curious about something. My 3.0L Mercruiser has serial number B523519 right on the valve cover on the tag. I need a new mechanical fuel pump, and looking on the Iboats parts section, the fuel pump I believe that is correct for my motor is Sierra part # 18-7278. It says...
