    Water in fuel

    Every fall I fill both my tanks with fuel after adding fuel conditioner. I fill the tanks right to the filler spout, eliminating any air in the tanks. (Yes, my tank vents are working.) Every spring, like clockwork, my 90 HP 4-stroke Mercury loses power and stumbles on the first run. I...

    Mercury OB shift linkage

    Remote control is hard to shift, more so in reverse than forward. The problem seems to be with the motor shift linkage, as the cables and control lever move freely when cables are not connected. Any ideas about what could be sticking, and how to free it up? I'd rather not tale the motor...

    Noisy trim pump 90 HP Merc O/B

    After a bumpy ride over a logging road, the trim pump has become quite noisy in the down direction. Up seems to be normal. I've drained and replaced the hydraulic fluid with Mercury trim fluid, and worked the motor up and down numerous times to get the air out. No joy. It still sounds like...

    E10 gas and winter storage

    I've been told that E10 gas separates out after about 90 days storage. Do any 'experts' know how much water E10 gas attracts when it separates? It's approaching winter again, and time to store the boat (outside). This past season I had problems with water in the fuel (presumably from...

    Will trim tabs help?

    I have a 17' welded aluminum deep V boat, powered by a Mercury 90 HP 4-stroke outboard, that tends to list to one side when on plane. Even shifting a 20 lb cooler from one side to the other can make a difference. At times the boat seriously lists with no visible shift in weight loading. I...

    Mercury O/B intake silencer

    Hope this is the right forum.....this is more of a maintenance/tweak question than a repair. I have a Mercury 90 HP 4-stroke that is noisy as all getout at planing speed. I see that an induction silencer used to be part of the intake, but is no longer available. I'm thinking of scouting...

    RACOR fuel filter

    I have a 2002 Mercury 90 HP 4 stroke O/B with a RACOR S3220TUL fuel filter ahead of it. The local jobbers sell the S3220TUL as a fuel filter/water separator, but when I go to the Parker Racor website and look at the specifications, the picture gets hazy. Parker lists two similar filters; the...

    Mercury impeller replacement kit

    I bought a Quicksilver 47-43026Q06 impeller replacement kit for my 90 HP 4-stroke Mercury O/B. In addition to the parts I obviously need to replace, the kit contains 2 large orange o-rings, 2 smaller yellow washers (?) and 1 small orange o-ring(?). I can't see any place where these belong...

    90 HP Merc 4-stroke driveshaft replacement

    I pulled the lower gear housing to rebuild the water pump, and got a nasty surprise. There was a bronze bushing stuck on the driveshaft, about halfway up. It doesn't appear in my drawings for the motor, so suspect it may be something that's used only with long leg motors? (Not sure I've got the...

    Merc 90 HP 4 stroke

    Another question about my Merc. I've had it about 5-6 years, and other than change the oil and filter annually and change the leg oil, I haven't done a thing to it. Oh, I did change the plugs a couple of years back. Is there any major service I should be contemplating? Or run it until...

    Merc 90 HP 4 stroke water pump

    My 2002 90 HP Merc outboard is still running on the original water pump, as far a I know (bought the boat 5-6 years ago). The dealer estimates $200 for the pump and about $350 labour to change it. I'm thinking about doing it myself. I'm pretty handy with tools, and have everything I need for...

    Trouble launching boat off bunks

    My 17' aluminum boat doesn't slide easily off the bunks. I have to back up and hit the brakes two or three times to get it to slide off. I changed the height of the bunks and even extended the trailer reach 2 feet, but that didn't do the trick. I'm thinking of getting some teflon or other...

    More chartplotter problems

    I bought an Eagle FishElite 642C iGPS chartplotter last year, put it in the boat and it worked fine. This year I turned it on and the display screen is very dim and flashes repeatedly. It seems to track otherwise (although so dim that it's impossible to read unless you get right up to it)...

    Power trim shudder - 90HP 4-stroke Merc

    I didn't find any info in the FAQs, and a search of 'power trim' returns 500 hits. I won't live long enough to read all of them, so am hoping someone can help me out here. On the first trip out this year, I discovered that the power trim won't trim down while the boat is on plane. There's a...

    90 HP Merc 4-stroke spark plug change?

    How often should I change spark plugs? I've had the boat and motor for several years, and haven't been having any problems. The previous owner was a mechanic, and was anal about the maintenance. I go out on the west coast (BC) and don't want to get stuck one day, is all. So, maybe this...
