    Distributor compatible between 3.7 and 3.0?

    I have a running 470 which I am not pressed to make changes to, but I have a newer distributor and ignition from a 3.0LX and was wondering about compatibility. I know when I upgrade from the points to the electronic ignition on the 3.0 it madea really big difference in in starting, idle and...

    EST Ignition Shift Interrupt Switch Wiring

    I have converted from a points distributor to a HEI EST iginition (got a deal on a whole wiring harness + distributor and alternator setup). I have it running, set initial timing etc., but wanted to confirm the shift interrupt wiring. I am almost positive that the EST sends a 12V signal to the...

    Merc 3.0 Low Compression 2 & 3

    OK, so sounds like the head gasket is blown between 2 & 3 which seems to be a common problem. Compression test gets 135, 85, 80, 130. Couple questions before I tackle it. Engine runs good, no water in oil, etc. 1. Am I confident enough to just order a head gasket and rocker cover gasket and...

    Mercruise Engine Harness Connectors.

    I got an EST distributor that came complete with the wiring harness. A lot of the leads terminate in connectors that look like this. My question is does anyone know where I can get similar ones to plug in to em? My sense of neatness (and being able to work on it in the future) won't let me just...

    Implications of burnt out resistor wire

    I have a 1988 3.0. Running OK, but I noted I am getting 11.5V at the coil (stock) when idling. Per other posts I should be seeing 4-9V or so, so I am guessing my resistor wire is bad. From what I understand, what will happen in this case is I will be burning out my coil and points quicker. Is...

    Benefits of going to EST Distributor?

    OK, I can't seem to find a lot of information on this, people say it is an upgrade, but wanted to find out what the actual differences are in going from a 1988 points distributor to a later model EST. My guesses are: 1) More consistent timing (no mechanical advance weights) 2) More consistent...

    3.0 Missing on cylinder 3

    I have a 1988 Mercruiser 3.0. It seems to be running well for the most part, but when hooking up a timing light I can tell that it is missing occasionally on cylinder #3 only. Timing is close (8btdc, will adjust to 6 but that's not the problem), dwell is good at 30, and I have pulled all the...

    Tightening up sloppy steering

    I have an 1988 Maxum (Bayliner) with rack and pinion steering that is a little sloppy. I know I can add a bushing of some sort to tighten things up at the transom, but is there any way to adjust/tighten the actual rack part of things?

    1988 3.0 Carbuerator Dumping Fuel

    I have a 1988 3.0 which was running fine in my driveway (fairly new boat to me). I then trailer it over to the lake and it refuses to start. Looking down the carb it looks like it was just dumping fuel. I had figured I had knocked something loose driving over. It would almost start and sort of...

    Removing seat boxes - Structural?

    I am redoing part of the floor on a 1988 Maxum 2000sr (bayliner) and the drivers side seat box was rotted and frankly I wanted to tear it out and do a captains chair on the drivers side in any case (although I would have put that off if it hadn't been so rotted). First, how awesome is it that...

    1988 Maxum 2000SR Partial Deck replacement.

    So bought a 1988 Maxum 2000SR and it had the back half of the deck replaced previously. Badly. So of course what started as a see what it looks like ended up being tearing it back up of course. The stringers were actually fairly solid. I know there is some rot around the drain hole in the...
