    merc 260 q-jet fuel drips from boosters

    I've had this boat since 2014 and it runs pretty good. Its a Mercruiser 5.7 with a q-jet carb. Last night i just happened to look down inside the carb while it was idling on the hose and noticed there was fuel dripping from the boosters. It was running perfectly. Idling around 700rpm. I didnt...

    what do you guys think of this as a replacement engine? 602 crate.

    I'm shopping for a 350 mercruiser and a friend who races dirt cars told me to look into a "602 crate" engine from GM. They're factory sealed for a specific racing class. They can be purchased used for reasonable prices. Here are the specs...

    Ran engine out of oil, what do you think? Mercruiser 5.7

    I have a 22' wellcraft and last year I installed a re-manufactured mercruiser 5.7 and we used it all summer and really enjoyed it. However, at the end of the season my wife and I were out with another couple, going across the lake maybe 4300rpm, I was standing and driving not looking at the...

    Alpha 1 vibration only when trimmed full down

    i have a alpha 1 gen 1 on a 22' wellcraft with a 350. While on plane with the drive trimmed all the way down there is a noticeable vibration through the hull. As soon as i trim it up, even just a little, it completely goes away. Ujoints seem good. Engine alignment is not horrible but not perfect...

    my outdrive is sick :(

    Its an alpha 1 gen 2 thats leaking oil. It started as a few drips out of the vent hole on the top of the lower unit, I searched here and determined it was a leaky shift shaft seal. No big deal, I'll change the oil very often and top it off everytime before I go out to limp it along for the...

    Oil dripping from outdrive?

    There is a little hole in my out drive right where this arrow is pointing. Oil is dripping out of it. Everything works perfect, I just have to keep adding oil. Anyone see this before? What could it be? The hole looks like its supposed to be there!

    question about engine alignment...

    How easy should the tool slide in and out? Right now I can push it in pretty easily with one finger and pull it out with two if I tried, but I can certainly feel a small amount of resistance. Is that good enough?

    what should compression be on a 3.0L?

    I tested mine and got between 180-185 on all four. I looked through my manuals and couldn't find the spec. Its a 1993 3.0L with about 87 hours.

    Need to verify timing procedure for 3.0L

    I read through service manual 13 for the GM 4 cylinders, the timing procedure there doesnt say anything about putting the ignition into "timing mode". I found this procedure on this site: WHICH METHOD DO I FOLLOW? The inital timing on my motor is supposed to be 8 degrees. I used the...

    3.0 starter bolts broken off, pull motor?

    Somehow my starter bolts must have worked themselves loose, then from the torque of the starter it somehow snapped both bolts off inside the block. There are two bolts and they come up from the bottom. I dont see how I could possibly drill these out without pulling the motor. Anyone see...

    I think there might be something wrong with my boat, opinions wanted.

    Almost a mishap on Memorial Day

    My wife, kids, and I stayed at a State Camp Ground at a fairly small local lake (a little over 4000 acres) for memorial day weekend. The boat was in the water from Friday night straight through Monday. There is no launch in the camp ground and you have to use the one on the other side of the...

    another thread about bottom paint removal

    First, let me say I've researched this a ton. Anyway, my 1993 Larson has bottom paint and I hate it. I've been researching methods of removal for months. It seems that the best thing for me to try is going to be a chemical stripper. I will not be paying someone else to do the job. Im the...

    adding power steering to an alpha 1?

    Has anyone done it? Is it that hard? I'd feel better about my wife driving while dragging me behind the boat if it wasn't so hard to turn while running at speed. Seems like it would be fairly simple if I could find all the parts from a junk donor boat...

    Question about outdrive steering fin trim tab

    On outboards and outdrives without power steering there is normally a trim tab steering fin just in front of the prop that can be angled to offset the turning effect that the prop torque has on a boat. If this fin is missing or not adjusted properly it can put a huge amount of force back...

    First overnight boating trip, awesome

    The wife and I (no kids for this trip) headed out Saturday afternoon. We got to the lake around 1:30 and were surprised to see no wait at the launch. We did some boating, hung out with some friends, went to dinner at a place on the water, then headed to the island to spend the night. The boat...
