    Mercury 90HP 4 Stroke 2003 Impeller Change

    If 4's are like 2's the drive shaft comes up out of the LU and is oiled by the oil in the LU. On the bottom of the water pump lower casting is a pair (usually) of seals facing each other...one keeps the lower unit oil in the lower unit and the other keeps ambient water out of the LU oil. The...

    1980s Mercury 2 stroke 35 hp thermostat / not peeing

    1. Following the tube from the outlet to its source, what is it connected to? 2. If the empty housing you say you found may be where a stat is mounted on some engines of that class, take the cover off and crank the engine with the lower unit in water about 6 inches above the AV plate for a...

    83' 115hp Mercury, prop slip

    I did replace that water jacket cover gasket later on...never knew why......didn't have a thermostat as I recall and no instruments to indicate crankcase water temp.......but I had a helluva lotta fun!!!!!!

    83' 115hp Mercury, prop slip

    Totally agree with that. The OEM lower unit was a JOKE!!!

    17 vs 19 vs 21 Pitch?

    "And electric car power consumption.-----" Interesting nobody ever mentions what it took to get the battery charged, or built and its weight!

    2001 9.9 2-stroke - water in gear oil

    Well I suggested that......got no reply!!!!!!!! Last time I was buying some, they were blue, OEM, and were said to be better quality than original OEM seals. Never had one leak, just changed them anytime I drained the crankcase and refilled with new oil.

    1979 Mercury 80 HP

    I have a pedigree in modifying tools to get the job done...grinding off outer diameters of boxed end wrenches, taking an Acetylene torch and getting the handle on a wrench cherry red, with part of it in a bench vise and a pair of pliers or hammer to "tweak the necessary change in shape" is just...

    2001 9.9 2-stroke - water in gear oil

    I agree on the pressure test and a tub of water. I am the sort of person that doesn't fix it it it isn't broken (known to be broken...obviously broken). Going through the cost and trouble of ripping everything apart and hoping you get it all back together just to be doing it....probably...

    2001 9.9 2-stroke - water in gear oil

    What's the condition of your drain and vent screw gaskets. That's the easiest to fix and easiest to see in your pressurization and submerge testing. On Chris' comments, you don't need to remove the rear bearing carrier nut to address either of those comments. Other thing is the other place...

    Can I put a 28 hp Johnson on my 14' Aluminum Sea King?

    "Also, does it make a difference that I'll be sitting up front and not at the back as would be the case with a tiller setup?" Of course. Thousands of posts and conversations about tiller driven boats where the owner asks about the load in the aft section only to get replies of "move xxxx...

    Topped off battery with Distilled water....Why not with battery acid???? Opinions???

    I have about 15 batteries to keep tabs on and I thought the right answer was to keep all on trickle chargers constantly as long as they weren't in operation. Result.......you guessed it...even though the max current was only 1 amp, over time it boiled the water out, even with the newer...

    Can I put a 28 hp Johnson on my 14' Aluminum Sea King?

    I had a 14' Mirrocraft like these but with console steering from the rear seat and a 30 HP Merc Mark 30 pushing it. Ran out real nice and that hull was smooth riding on 10-20k acre lakes. Fishing buddy had a 14' Alumacraft with the same type of steering setup and a 33 HP Johnson. Ran out real...

    Anchor Industries Deckette Pro 160 16 foot Specs

    That hull is basically flat. A flat board is hard on your back in anything but smooth water. Back in the day, raising 4 kids and most Sunday's were boating after church, I looked into deck boats because initially I thought that would be just right for my family.....never happened and the main...

    83' 115hp Mercury, prop slip

    That's why Karl K. had 2 bladed props on all his engines for efficiency reasons.....fewer blades (over 1) the more efficient..... till he changed paint colors and started manufacturing 100 hp I6 engines for big, heavy boats. Some skeptics (I guess) claimed that his engines put out more HP than...

    83' 115hp Mercury, prop slip

    Some "guesstimates are that cupping adds 1" of pitch. Problem with attempting to verify that is that you would have to take a specific cupped prop, take it to a prop shop and have them flatten out the trailing edge of the blades and get back to the water under absolutely exactly (ha) the same...

    TILT / Trim

    I don't know....I was a Johny-Rude guy back then.....getting out run by every green/white/or black engine out there.....decided if you can't beat them join them. Haven't been sorry.....pretty much.

    2004 Mercury 115 ELPTO surging

    That will expose a lot of sins. Surging is fuel related and obviously RPMs fall off when fuel flow falls off. When the PO said he checked the onboard fuel filter (and there are 2 on that engine, a large one visible from the Port side of the engine with the cowling off and another much smaller...

    Mercury control compatability

    Probably since the year models are close and in the 1990's big changes in designs and colors had pretty much settled out for non technology changing idea adaptation. A quick look will tell you for sure. Faztbullet can tell you for sure. Ping him.
