    Water in gear oil

    SWAG: When filling, one inserts oil from below the gearbox and continues to fill till clear, solid, non-bubbly oil exits the vent just above the antiventilation plate. The upper drive shaft seals are beneath the water pump so there is some room for LU oil to expand at the top of that chamber...

    Prop slip and cavitation.

    Cavitation is minute air pockets formed when the oxygen is pulled out of the H2O mixture called water. Reduced air pressure, aka vacuum is what does this and in your case I'd say the rough character of your surface is the smoking gun. I have no idea as to how it looked when originally...

    Mercury 90hp 2 cycle

    Faztbullet, Racerone, Flying Scott to name 3 could answer that question. Ping one of them. The 3 and 4 cylinder engines of that time period are very, very similar in fact the manual from 1994to 2007 more or less is the same book with separate sections only for the 3 vs 4 cyl powerhead. Like...

    lower seals help needed

    The screw is a great idea too. Glad you were successful. "You gave me the motivation to give it another go." I find that my motivation is challenges that I have accepted and overcome over my life. Like seeking an answer to something: If you don't ask the question, how can you expect an...

    Hours? How?!

    And yet another is that you go out and float or anchor and have lunch and visit, enjoying being out on the water, then enjoy water sports, or vise versa. 2 hours of water sports is a lot of tubing, or skiing. Or you cruise around on a Sunday afternoon and run up the hour meter. I think...

    lower seals help needed

    You can leave the LU intact. Just remove the prop and thrust washer on the prop shaft and get to it. Drill a hole in the metal and take a pick, like a SSdental pick, stick it in the hole, or holes if you choose, and pry the outer seal out. Then you can grasp the metal of the inner seal and...

    Ports Working

    Was out a couple of days ago and running my usual 3000-3500 sweet spot at 20-25 MPH, nice comfortable cruise, no problem maintaining trim/boat attitude, soft ride. Decided to punch on out and get some WOT data also. Running the Mercury Laser II original square ported prop. Slip at the...

    115, 4 cyl, 2 stroke, 2+2 performance update

    Short history. Bought this used rig last summer and didn't like the performance. Problems to me were transitioning from 2 to 4 was rough and after getting on 4 it took awhile to clean the plugs out so that I could get WOT RPMs. Once they cleaned out, with the prop I selected I was sitting...

    Killing Time

    As I was tweaking the used boat I purchased last summer, I had a nice set of Farina gauges on the dash but in the center was a 3" unused circle. Thought about what to put there......Since I was not familiar with the engine and the existing water pump was doing a fine job from idle on up, I...

    Iridium Spark Plugs Anyone?

    I have a new to me, 2002, 115 HP, 2 stroke Merc. 4 cyl 2+2 engine. Playing around with it I've been learning how it works and what I could do to make it better. I decided to put in new fuel pump and accelerator kits, noting that the old diaphragms were much stiffer than in the new OEM kits so...

    PVS Plugs

    I have an early, like late 1980's Laser, for 115 hp engine, not the current Laser II, with square PVS ports. I want to close them and want to use rubber plugs. Is the 4 pack of square plugs, PN 19220A4 the correct square plug? Thanks

    Non engine related HP loss

    Without regard to anything but the posted subjects, HP is reduced: by 3.5%/1000' of altitude and by 1% per 10*F of ambient temperature above 60F. Picked this up on the www on a petroleum site discussion. What is needed to complete this is the relative humidity since (in my opinion) that has...

    Curiosity Finally Gets the Best of Me!

    Things are quiet so let's post something. I've noticed over the years that OMC engines get half again more postings as Mercury. Question I have been asking myself was, is that because of more problems, or more units in the field? Now I ask your opinion.

    Parts List

    Online Merc parts, couple of questions: 1. What are the public access codes, name and pw? 2. Once you go to all the trouble of getting to the part you want, how do you keep the site from timing out on you after just a few minutes which locks you out requiring #1 question info which you don't...

    Identifying a Trailer Hub

    Recently acquired a 2002 model Heritage Custom Trailer. Pulling up the Heritage www today, they talk about Vault Hubs on their trailers. Wondering what is on my '02. Peculiar end on the hub, like a solid, cast, (not stamped like on most non boat types with the lip for removal) steel cap...
