Hi,i have just bought what appears to be a yamaha 9hp but there is not a plate on the mounting bracket (just 2 corroded rivets) it runs ok a bit hot(on tick-over water coming out was quite hot) but i will check therm on top of head(as i can see one), i would like to know age and anything else about this engine.<br />All i can tell you is that it has forward/neutral/reverse gears,pull start recoil setup,2 cylinders,2 wires under carb doing nothing(my fingers crossed they are for charging system),gear and throttle are on the left of engine if looking at pull-cord,below pull-cord is a little button you pull out(only a short way) to start and to the left of that is a stop button. on the block is a number 65500 and F1 below the number, the engine is a short shaft.Sorry if all this is long winded but i thought i would try and give you all as much info as i can.<br />p.s. i take it it will be a 50:1 mix!.<br />thanks RAY
