Provided the propeller is submerged low enough in the water, the most likely culprit would be a spun propeller hub. This condition causes the propeller to slip free from the hub, thereby causing the boat to lose propulsion.
Yamahalube 2s (autolube 2 stroke injector oil)
Older models often have 1:50 ratio. Never have 1:100 This information should be on a sticker on the block or under the "hood"
Valentino Rossi drives a Yamaha YZR-M1 bike. He is currently under contract with Yamaha. The bike features a liquid-cooled, in-line, 4-cylinder, 4-stroke with 16-valve DOHC engine.
2 stroke engine power reed info: (works on outboard engines/ motorbikes, mowers & my brush cutter. hope this helps (google- boysen reeds) Reeds are one-way valves controlling the amount of air/fuel mixture entering the crankcase of your outboard engine, then sealing it in to prevent it from escaping. Every two-cycle outboard has them. But the stock reeds in your outboard have a single-stage design that limits their efficiently. That's why stock outboards often cough and sputter at idle, fail to deliver a good hole shot, feel boggy or lifeless under throttle application, burn too much fuel or lack top-end punch. Plus, standard reeds are made of metal. Should one break, it could cause extensive damage to your outboard.

The Yamaha Blaster is a oil injected bike, you put oil, Yamalube 2S, in the tank under the seat, then you put gas in the tank. You dont have to worry about mixing anything unless someone has removed the oil injection system and put a block off plate on it. Yamaha produced the Blaster, a 200cc air-cooled single cylinder two-stroke ATV as an entry-level machine from 1988 to 2006. The Blaster was discontinued for 2007 and was replaced by the entry-level Yamaha Raptor 250, which uses a cleaner burning, four-stroke engine.
outboard motor will start and idle, but dies out under load
Under the engine.
middle bolt right under crank cake side... where it says yamaha.. right under that.
under the seat where the throdle screws in the carb, there is an adjustment screw, turn right and it increases the idle. it worked for me. do it while running. It is a large flat head screw that is on the throttle body control mechanism. Not on the carburetor itself.
go to www.nada.com look under consumer then outboard motors find the model number and year
You will need to remove the throttle body and replace the throttle body gasket. The throttle body gasket can be purchased at most auto-parts stores.
