    Should I convert to disk brakes ??

    I've got an 18 foot SeaRay bowrider (outboard) on an Eagle trailer. I estimate the total towed weight to be 3,000 lbs or maybe a little less. I recently saw a complete disk brake conversion kit for $299.00. Seems like a good price to me. I'm not having any troubles with my drum brakes, but...

    DIY: The ultimate Oil Injection protection

    As we all know, having the proper amount of oil mixed in the gas of our carbureted 2-stroke outboards is critical. Automatic, variable oil injection makes our lives much simpler (and cleaner), but if the oil injection system on your outboard fails the result is catastrophic. All carbureted...

    DIY: Repair seal wear grooves on drive shaft

    I have a 1998 115 2+2 with 800 hours on it. This winter I replaced the water pump impeller and decided to replace the seals under the water pump housing. When I removed the seals I noticed that they had worn grooves in the sealing surface, which would reduce the life and effectiveness of new...

    Questions about fixing lower unit oil leak

    I have a question about the oil seals under the water pump on my 1998 115 Merc. I bought the engine new, and from the first oil change I was concerned about the appearance of the LU oil. It has always been a yellowish color. This year I decided to replace the seals under the water pump...

    Does my 1998 115 have a plastic oil pump gear ?

    I've been reading about oil pump failures on larger Mercs, generally attributed to a plastic gear on the crank that fails. I looked at my parts manual, and I see that my pump is driven via a gear on the crank, but the manual doesn't state what material it is made of. It also appears that my...

    What temp should my 1998 115 run at ?

    I bought my 1998 115 new in 1999. It has 700 hours, and I run in on a SeaRay 175 bow rider. When I first bought it the temp would run around 145 degrees at idle, and when I put the hammer down I could watch the temp gage move quickly down to the low peg on the gage. At the time, I asked my...

    QuickSilver vs Michigan Wheel ??

    Hi, I've been running a QuckSilver 12.75 x 21 prop on my 1998 Searay 175 bowrider with a 1998 Merc 115 2 stroke. This prop has been doing pretty well (4900 rpm @ 41 MPH with a medium load). I'm looking for a new prop, and I don't know if I should buy another QuickSilver or maybe a Michigan...

    1998 Merc 115 - small loss of power

    I have 600 hours on my 98' Merc 115. I bought this engine new (on a SeaRay 175 BR), and it has always run very well. This season it didn't seem to be running right, so I did the following: Rebuilt the Fuel pump Rebuilt all carbs & replaced float valves Replaced spark plugs & wires Checked &...
