    Mercruiser 5.0 misfiring and taking on water

    I have an 87 mercruiser 5.0 with a chevy 305. I rebuilt the carb this year after de winterizing and ran the boat 3 times with only minor adjustment issues. This weekend I took it out and I noticed at first it would intermittently not get on plane right away at WOT. After fishing at idle for a...

    86-87 alpha outdrive overhaul

    I posted this before, so forgive me if I sound repetative. I've been doing a lot of internet research and have become very concerned about this issue. I have an 86 or 87 alpha one outdrive. I got it last year and it was making this noise when I bought it. I have taken it out for 6-7 times since...

    88 Mercruiser 5.0 alpha one outdrive making some crazy noises when turning

    So my alpha one outdrive has made this intense almost honking noise when turning.... When at slow idle it clicks sometimes... There is no clunk when going into gear at all just a loud consistent noise when turning that vibrates the boat or is so loud in your ear that you think the boat is...

    Rochester quadrajet rebuild

    Just rebuilt my 1987 mercruiser quadrajet. It was a 17080565. My question is that my mixture screws (the adjusting screws on the bottom of the carb 2 of them) were at different turns out. My rebuild kit said both should be 3-4 turns out. On my old one, it ran great at idle before sitting all...

    Mercury 1150 about to be sent to the dump

    Mercury 1150.... honestly not sure of the year the serial says it doesn't exist when i look it up the rectifier says 73 on it, but I have always thought it was a 74. I bought this from a guy who said he took it a mechanic every year and was a reliable boat. Ever since I've had it, it has been...

    Ongoing problems after stator change

    1974 Mercury 1150 I6. Ran Great 2 weeks ago but wouldn't charge battery. Replaced stator and rectifier. Boats idle changed and in turn boat wouldn't stay running at idle. Checked timing, when at TDC 0 on flywheel, the mark on the pulley above the distributor didn't line up (it was one tooth to...

    1974 Mercury 1150 has new rectifier/stator and now won't idle

    1974 Mercury 1150 was not charging battery. Replaced stator and rectifier. Old rectifier was rectangle with 3 posts. New rectifier does not fit properly it is much smaller and triangular. Marked bolt hole when I took off the flywheel and am pretty confident flywheel is on properly. Timing should...

    Rectifier Replacement

    Where is the rectifier and how do I transfer the wires from the original rectifier to the new rectifier Sierra Part Number 18-5707. If I am correct in what I am assuming to be the rectifier (indicated in green), the rectifier I have is a straight vertical 3 post setup. The new one has a...

    1974 Mercury 1150 stator issues battery not charging

    So I've had this problem once before. I own a 1974 Mercury in line 6 1150 that runs fantastic. I have been going through replacing wires like crazy because they were all corroded. A while back the boat left me stranded on the lake. The starter would engage the flywheel but didn't have enough...

    1974 mercury 1150 I6 Impeller change.

    Bought seloc manual and sierra replacement kit (gaskets and impeller without housing or base). While researching the procedure on this the manual confused me more than it helped. First, it is unclear how it all comes apart and what linkage might need to be disconnected.... I think I can figure...

    Tillotson 501061 wb25a Carb Rebuild

    This is off of a 4 cylinder 120hp with 2 carbs. Did the breakdown according to the manual but one thing is puzzling me. There is a step that says remove main nozzle or back of the main nozzle until it is loose and then remove it. So I took out the main jet and inside the center turret is what...

    1976 Chrysler 120 hp backfiring

    Heres the most brief recap I can give: Bought a 1976 chysler 120hp outboard (2 stroke) Previous owner said engine always ran great until the last time he took it out but that he replaced spark plugs and they were old and fixed problem. I took boat out and it didn't like to shift into gear...

    1976 Chrysler 120 HP 4 cyl with 2 white spark plugs and 2 normal whats the deal

    Hey, So I recently took out a boat I just purchased for the first time. I noticed a few things about it and am not sure if they are interconnected or not but my main question is why is it when I checked the 4 spark plugs that the upper two were white and the bottom two looked pretty...

    JB Weld On Bow Eye???

    I posted on here before about my 1975 Tahiti having a barely loose bow eye. When I say loose, I mean that the rear end of the loop has slightly more sticking out than the front. There is a tiny bit of wiggle back and forth but extremely minute. I have gently tapped the U bolt with a hammer and...

    1975 Tahiti Bow Eye Problem

    The factory bow eye is just starting to pull out on one side about 1/4". It is still pretty good but does have a tiny tiny bit of wiggle to it. It looks like years of pressure from pulling it out of the water has caused it. When I look at the bow, I have no idea how I would get inside to find...

    1976 Chrysler 120 HP outboard Lower Unit Seal Problem

    I recently purchased a 1975 Tahiti with a 1976 Chrysler 120 Outboard Model 1209HD. It started and ran great but I only saw it run on a hose attachment. Once I bought it, the first thing I did was run it in a bucket of water to see if the impeller was in good shape. I removed the lower unit and...
