    Oil injection delete

    I have a 2002 115 2 stroker and had the same year 90 2 stroker. On both engines all I did was to unscrew 3 (as I recall) screws on the oil pump,( in close proximity to the inlet fuel hose inside the engine cowling), temporarily disconnecting one short hose (which I reinstalled when finished)...

    Why is gear oil leaking out of lower unit when running?

    I'm going to say that your water supply to/at the engine water pickup is inadequate on the muffs, if you don't have water impeller pump problems or sticking shut thermostats or if running at higher speeds on the hose, the pop-off valve stuck shut.

    2019 Mercury 20HP EFI 4 stroke, hard initial start.

    Depending on the layout of your boat and fuel distribution constraints, maybe it needs some help. My 2 strokes have fuel pumps too but you have to get the fuel within the operating range of the pumps and that is the problem with first starts. I didn't change anything in the engine, just...

    Title Issues

    In Texas there is now a method whereby you can register a lost title boat to a different owner. There are certain conditions where that is allowed. Texas Parks and Wildlife site (a self funded state agency) is where you pick up the forms, fill them out and with the fee, send the application to...

    Prop Help

    Lot of verbiage here but I see a deep V, high dead rise at the transom boat meaning that the engine height is OK, if not a couple if inches too high....but that might not be a problem or may be. My first thought is pull the aluminum prop, throw it in the trash and install a good quality SS...

    2019 Mercury 20HP EFI 4 stroke, hard initial start.

    Nothing! Ok, here's something: I have/have had 2002 90 and 115 2 stroke Mercs. First start of the day is hard for me too. Problem is getting enough fuel to the carbs to get things going. I am finding problems with current issue squeeze bulbs acting like they are delivering fuel but not...

    89 Mercury outboard 100 hp shift shaft alignment

    If you only changed the water pump your lower unit should still function. The shifter splined shaft (stub) sticking out the top of the LU is embedded in a piece of metal (bar) at the front of the LU, internally. On the other end of that bar are 3 detents, each being a different dimension from...

    Repair and owners manual v150 Mercury

    ebay is where I get mine, both new and used are available, prices seem reasonable...you know the shipping charge right up front as they are usually shipped free....obviously the shipping fee is already contained in the posted price and shipping for most of what I buy is just a couple of days or...

    1990 Mercury 175 Overheat warning possible causes?

    The stats are for slow speed heating the combustion chamber to prevent fouling and better combustion. The poppet is larger in area than the stats and essentially opens the combustion for full flow of cooling water at the higher speeds. For my 4 cyliinder Mercs it happens at about 2500...

    Spark Plug Half-Fouling

    I totally agree on surface gaps. The Mercury service manual for my engines lists surface gaps and a conventional gapped plug alternate. On the location of the carbon buildup it depends on the fuels position within the combustion chamber when the plug fires. Fuel enters in a swirling motion.

    90 HP Mercury 2-stoke troubleshooting starter

    The spinning starter drives the gear up the shaft. When you remove power to the starter the spring is supposed to return the gear to the motor end of the shaft. Probably rusted and just stuck. With the gear engaged in the flywheel, the starter motor will either turn the flywheel or the...

    Advice for Portable Fuel Tank Mercury 115hp Command Thrust

    I had a fuel pump on my '88 115 tower and my current 2002 115 4 cyl looper. Funny as a teen, I didn't know why OMC used a dual hose to their tank even though you had to pump up the tank and didn't understand why just that you had to do it to get the enginestarted to use it but I thought it was...

    Surprise My electric car is not charged.

    Watching the TV program, CSI Miami, there is an awful lot of real estate that isn't very far above the surface of the water.......boy is that going to be a mess one of these days. May have to do something like NOLA and install sealed bulkheads and pumps.

    Starter fluid everytime....

    Amazing the difference between choking effect of a closed choke vs a 90% closed choke. Some of my lawnmowers are real picky that way.

    This isn't a boat post but it can effect every boat with a squeeze bulb fuel primer, regardless of the brand of the engine.

    I cut the two open to see why they were so hard to squeeze. The OEM had 3 layers of rubber...the outer shell and an inner adjacent to the outer. Then inside was a separate, shorter, narrower, thicker sleeve and probably was the big reason for that being so hard to squeeze from the onset. The...

    Advice for Portable Fuel Tank Mercury 115hp Command Thrust

    My current boat is a 2002 model with a 24 gallon built in tank. I don't boat very often any more, and when boating don't stay out very long and don't use much fuel. I didn't like the idea of that large tank and trying to ensure that I had fresh fuel. I bought a couple of portable 6 gallon...

    Small and light boat for 5+ people?

    I bought a new 1971, 16' Chrysler Sports Fury fiberglass tri-hull with an 85 HP Chrysler engine for my family of 6....4 smaller children. It was light and very stable being a tri-hull and at the transom was pretty flat. Had plenty of power to pull 2 kids at a time on skis and room enough...
