    Determining Max Outboard Engine Size

I have been going through the old pamphlet for my 87 Aquasport 200 Osprey as well as different engine specs for the yamaha outboards. The 200 osprey has a max hp rating at 185 but the 222 osprey has a rating...

    Engine Upgrade, 115hp to 225hp

    My current setup is an Aquasport 200 Osprey with yamaha 115hp 115ETLH motor. Motor is a 1987 and running decent. It needs to have the carbs rebuilt and engine tuned but overall gets from point A to point B with little worry. I would keep the setup I have and just tune the outboard and rebuild...

    More Power in Yamaha 115

    1987 Yamaha 115 Running Issues

    I have a 1987 yamaha 115ETLH outboard. It has trouble idling and will shut off every now and then. When we are in a long no wake zone and running just in gear it will also shut off at times. I am not sure if the idle is just set to low, it is around 600-700 I believe. Every now and then I...

    Gas wont Flow

    We were out on the ocean the other day and i could not get the engine to start. We hadnt run our 1987 yamaha 115 for about a month and towed it two hours to take it out on the ocean. I went to prime the bulb and all i heard was air. I could not get any gas to pull which meant that there was...

    New GPS/Sonar

    I am looking to eventually take my 20' CC to the ocean for offshore fishing. I really dont want to be out on the ocean without a GPS unit. There are so many options available so I was wondering if any one has had luck with certain brands or models. I was originally looking for a 5" due to the...

    4cycle vs 2 cycle oil and maintenance

    I have a 20' center console with a yamaha 115 outboard 4cyclinder with the precision blend 50:1 system. The original owner of the boat used to put 4cycle 30weight heavy duty oil in the tank. He told me to do the same but after looking through the yamaha manual and checking different products...

    Looking for more speed

    I have a 1988 20' aquasport with a yamaha 115 outboard on the back. It is a 4 cyl and runs pretty well. I have changed out the plugs and installed a new oil sensor unit which solved my oil problem. It seems to run really smooth and I cannot complain. My Step father in law clocked me going at...

    Oil Reservoir Tank wont quit filling

    I have a 1987 yamaha 115 outboard. The reservoir tank seems to continually fill even though the float is all the way up and the tank is full. It will actually push the cap out and overflow oil into the motor housing. Not fun when this happens on the lake and i have to continually add oil...

    Oil Cap on Yamaha 115 Wont stay down

    I have a yamaha 115 that has an oil issue. When running the motor through the RPM range the oil cap on the main reservoir will pop up and leak oil. I have tried clamping it down but then the engine wouldnt run over 2000 rpm and smoked liked crazy. All the wiring looks correct. I had the key...
