    Mercruiser 3.0 - Throttle sticking between 3/4 and full

    Hey guys, Took the boat out last weekend and when I move the throttle between 3/4 and full it gets hard to push down. I can give it a little effort and it pops down to full and the boat accelerates. But when I go to back off the throttle a little and hit that same spot, I have to pull up and it...

    Trim Tap "Up" not working

    Hey guys, I'm a little baffled here. I replaced both my trim pucks last year and installed a gauge. The up was not working at all and there was no gauge. After installing and calibrating, they were working great. They never saw the water before boat was winterized. Just fired up the boat...

    Will wrong ignition coil cause running issues?

    Where is Cylinder #1 on 3.0

    Boat is a 1988 FourWinns and engine is a 1988 3.0. I replaced the head gasket at the end of last season. I buttoned it all up this past weekend and fired it up. It was skipping like crazy at idle. I thought the engine was going to jump out of the boat and drive down the street. I checked the...

    Stern Drive question

    Hey guys, Quick question. I replaced the water pump a few weeks ago and when I put the lower end back on, I messed up the linkage somehow and now won't go in to gear. I pretty much know what I did and how to fix it. My question is, I have to take the whole outdrive off to replace the Trim...

    Bad Trim Switch

    I found that my trim switch appears to bad. Trim will go down, and trailer works, but I have no up. Trim limit switch seems to be good. I took the switch out and messed with it a bit and got it to go up but VERY sporadic. I went to local marine store, but they said they don't carry and I need to...

    Broken bolts on Trim Limit Switch

    Hi Everyone, I just picked up my first boat yesterday. It's an 88 Four Winns Freedom 160. I was going through it today to make sure everything is working. A few odds and ends things, but what I noticed was that when I tried to use the UP trim on the throttle, I got nothing. Down works and so...

    Engine runs fine, prop will not spin

    Hello All, The guy I bought the boat from stated that the engine needed a "coupler" and that was why the prop would not engage. Engine seems to run pretty well. I plan on heading to the boating store tomorrow and hopefully get a manual for the engine. Is there anything I should be checking for...
