Serial # OD289720
I just installed a new trim motor and filled it up with oil. It trimmed down and actually trimmed up the first few times I tried it. Then it would only trim up every 3rd or 4th time you try it (relay clicking). Now, it won't trim up at all.
The UP relay is clicking. I...

It's the trim assembly with one ram. Here's the diagram of what I have:
I called a local outboard shop and they said Mercury replaces this pump with a different pump (better) that bolts right in. You cannot get the parts as listed on the diagram anymore, you have to...
My lower unit is toast....My upper unit seems ok...my gear oil had water and metal shavings in it....Can I flush my upper and mate it with a "used but good" lower?
If that doesn't work....
I have another upper but the U-joints are seized up... Can you take the U-joints and drive shaft out of...
I had an earlier thread about my drive problems, but I have a new question, so new thread:
I have an 87 Alpha One with 1.5 ratio. I found an Alpha One Gen 2 (late 90s model) with 1.47 ratio for sale locally. What would I need to do to install the Gen 2 on my boat? Is it plug and play or...
We were just cruising along yesterday, celebrating the birthday of our great nation when the drivetrain started making noise and vibrating the boat. My first thought was lower unit, but it was making noise in forward, neutral and reverse and it sounded like it was coming from the back of the...
I asked this in my other thread, but I guess it's too crowded with ignition talk to get an answer on the switch wiring.
I just need to know if the Interrupt Switch is normally open or closed with the roller in the valley?
Mine is closed, meaning there is continuity between the two posts when...
I can't really verify what kind of ignition system came factory on this Mercruiser 5.7, but I think it was points. What I found on the boat when I inherited it was an automotive HEI unit. And it ran great, but I wanted a marine set up for safety reasons and the Delco EST was recommended on...
1987 Mercruiser 5.7
I currently have an automotive HEI Distributor (My Delco EST arrives today and will be installed ASAP). It has one red wire (12v) and one gray wire (to Tach). Upon researching some wiring diagrams, I don't think the red wire is factory. It was probably wired up by the PO...
This is for the Chris Craft in my sig:
I don't have a Mercruiser stamp or tag anywhere on my engine, but I do have the #'s off the block. On the starboard side top of block in the rear above the starter is has 10243880. I believe this is a serial number or ID # of some sort?
The Rochester...
So I bought the boat with an auto HEI Distibutor. I know of the safety concerns and I want to remedy this, but would like to stay with HEI or some other all inclusive distributor. What Marine HEI distributors are out there? Budget oriented, please. And how much power will I gain seeing as...
I've had the boat about a year, but just got it running last fall and just now starting to really get it going and start tweaking things.....

1994 3 cyl 50hp Merc 2 stroke w/ oil injection
I obtained this boat/motor about 2 years ago. The oil injection did not work. The oil reservior stayed full. So I just mixed my oil with the gas the old fashioned way. All the sudden the motor magically started using the oil from the reservior...
1) Performance issue you are trying to correct.
- Not sure yet. I'd like some opinions whether the boat is capable of higher cruising speeds / top end and MPG
2) Current prop manufacturer, model, aluminum or stainless as a minimum.
- Boat currently has SS Merc 3 blade 13 3/4" x 21P...
