    shift shaft alignment question

    Well... I've changed all the oil seals on the lower unit, and the last one to do was the one at the top of the shift shaft. Not sure if I did this in the correct order or not. I pulled the shift shaft out and replaced the seal, but now it seems I am unable to get that shift shaft to fit back...

    2001 Mercury 2-stroke 90 - what to look for?

    Hi guys I've found a sweet looking 2001 ELPTO Mercury 90 2-stroke that appears to be in good shape, used mostly in fresh water and well maintained. The seller claims it's had a recent water pump replacement, T-stat, leg oil, and fuel filters. Compression is said to be even on all three at...

    telltale not showing water?

    2006 Merc 50 4-stroke EFI that has about 50 hrs on it. It was used in saltwater for one year, but now always in fresh water. It gets stored outside and endures temps well below freezing. I always winterize it properly. This spring upon starting it with muffs, then in a garbage can full of...

    Is the Merc 90 2-stroke a good motor?

    I've been keeping my eyes open for a good used motor. I am presently using a 1998 60HP 2-stroke, with a jet pump (40-45HP). It's a great motor and I've had no real complaints about it, but I would like to eventually replace it with a 90HP 2-stroke (65HP at the jet pump). I've pretty much...

    4 cylinder Yamaha 90?

    A guy tells me he knows of a 2001 90 horse 4cylinder 2 stroke Yamaha. This particular one has a jet on it. I wasn't aware that Yamaha ever made one of these. Can anybody tell me anything about it? Reliability? I'm guessing it would be heavier than the time-tested 90 triple? thought I'd...

Used 70% as a trolling motor on a 15' aluminum skiff, which weighs around 1000lbs, in fresh water. rest of it's life is spent on a 12' jonboat, primarily for getting from point A to B, running at or near wide open.

    94 Octane Marine Gas?

    Where I live in Canada, I can buy dyed gas labelled 'marine gas' for a cheaper price than 'regular' gas. It is dyed purple, but it's 94 octane, compared with the regular stuff which is 89. My boat motors run very well on this stuff. I have heard that this gas is 'hard on the riggin'. I never...

    no water pump gasket, 1998?

    So I dropped the lower unit on my motor, and lifted the water jacket, only to find that there is no gasket between the water jacket and the face plate / top of the jet pump on my motor. My shop manual shows that there should be one there. I am pretty sure this is the way it came from the...

    need some prop expertise...

    I am getting closer to having my boat dialed in, but I'm still not there yet. I have a bunch of props at this point, none of which are really perfect. My motor is a Merc 50 4-stroke, and the boat is around 1500lbs, aluminum skiff, with a small tunnel. I suspect this makes it somewhat of a...

    Honda BF5 drips oil...

    Hi guys It is a 2003 motor, with around 110 hours on it, and has been regularly maintained. It slowly drips oil, and I notice that it occasionally gives off a smell of fuel. I believe this is originating from the carb. I have a mercury 50 4-stroke that runs all season without a drip of oil...

    BF5 - Synthetic Oil?

    I have a great little 5HP honda, and it spends 50% time trolling, and 50% used as primary power for a small skiff. Probably gets in the neighbourhood of 20-30 hours a year, and I change the oil annually. The motor probably has around 100 hours on it now, (2003 model). When I change the oil...

    60 triple hesitates....

    Mercury 1998 2-stroke 60HP three cylinder, called the '45 Jet'. It came from the factory with a jet shoe instead of a prop. I bought the motor 2 years ago, and prior to my getting it, it sat unused for 3 years. Carbs were badly varnished, and I had them re-built and cleaned by a local...

    Posting this, in case anyone is interested. Using a Quicksilver stainless 11 5/8 by 11" prop, on a 15' heavy-duty aluminum skiff. Tiller Drive. Holeshot is just over 3 seconds. This propeller over-revs slightly at WoT. Figures obtained using a gps and a Mercury smartcraft guage. 4000 RPM...

    water in lower unit

    I am in the process of winterizing an '06 50HP outboard. The lower unit oil is a milky green colour. This indicates to me that a small amount of water is getting in there. There were no metal particles on the magnet, nor was there any water that came out when I pulled the drain plug. Gears...

    Replacing Vengeance SS, need less RPMs

    After trying a number of props, I've found a Quiksilver / Mercury Vengeance SS, to be the best performing prop for my setup. However, WoT RPMs are too high - Mercury 50HP 4-stroke EFI, tiller handle. Recommend WoT RPMs 5500-6000 - Quiksilver SS 11 5/8 by 11 Pitch prop - GREAT holeshot, 31...

    Questions about warning buzzer...

    My 1998 2-stroke 60HP Merc doesn't beep when I turn the ignition on. I tried grounding the tan/blue wire from the wiring harness. With the key on, it gives me a loud beep. I pulled out the temperature sensor from the water jacket, and confirmed that it appears to be opening when it goes in...

    Prop Slip as an indication of power...

    Can anybody shed some light on whether or not an underpowered boat would typically show higher prop slip #'s? Or is there no correlation between prop efficiency and power? I am showing 12% slip with my present setup, but my holeshot is very slow, and my top end is around 25% less than the...
