    Intermittent no start problem.

    Occasionally, my 89 3.0 liter IO will not crank unless I turn the key to start position a few times without touching any of the controls. I thought it was the ignition switch, thinking it was old. replaced that. Thought I could hear the solenoid on the starter click, so I replaced the starter...

    New prop for my 3.0 mercruiser results

    My 1990 mercruiser 3.0 bowrider came equiped a 19 inch 3 blade prop. On accel from Idle, engine bogged a bit, took a bit to come out of the hole onto plane. At 3000 rpms, it runs a fuel efficient 30 mph and felt light , but on turns felt sluggish and boat lost speed. Top speed was 43 MPH @ 4300...

    Good day at the lake

    My new to me (1990) 18 bowrider with the 3.0 mercruiser and alpha one ran well. Been working on this boat fixing things the original owner just put up with. Good speed out of it also. 3000 rpms gives me 30 mph on the GPS and the top rpm of 4300 nets me 43 MPH. I was considering buying a new 19...

    Ignition coil question.

    Seems like I need a new ignition coil for my 89 3.0 that uses points in the dist. My question is, the original coil says on it, External resistor required. I have been able to find ignition coils at my local auto parts store that say this same thing, so Im they will work just fine. But, I can...

    Lack of performance 3.0

    Boat new to me, 1989 bowrider 3.0 liter engine. Standard 19 inch alum prop, max RPM I can achieve is 3000 with a light load and engine sounds like it laboring ,meaning a lot of intake honk. Speedo inop, but Im guessing maybe 30 MPH at best. This is less then I expected. Since ignition timing...

    Trim problem

    Just bought an old 89 3.0 liter I/O boat and noticed in my yard the trim didnt work all that well. As I activated the button the motor would rev up then slowly die off when either going up or down.Thats the first clue. Tossed into the lake today, noticed the trim really didnt work all that well...

    Aniother thing for the launch check list.

    This is my first I/O and my first test drive after a cold winter. On the way to the ramp, I told the Wife to remind me to put the plug in before we tossed it into the water. She forgot to do that, but I didnt. Anyways, we are zipping around the lake for about 20 minutes. The new boat( to us) is...

    RPM's reading high

    I just bought this 90 equipped with the 3.0 and the tachometer is reading a bit high. It has the original gauges that it came with and the tach works, just reads about 500 -750 rpms high and something the gauge flickers higher when the engine has not changed RPM's. I Have not had the boat out...

    Running rough at cold start

    Im new to mercruiser 3.0 so excuse my ignorance. I bought this 1988 3.0 and it runs very rough at initial start up, in our 40 degree temps. I found that the choke plate is in the completely closed position until the engine is running for about 2 minutes, then it starts to open and then the...
