Looking at a used 1995 Century 2300 with a 1995 Yamaha 200 hp 2 stroke. Owned by friend who uses it for fishing charters on lake erie. He is asking $17,500. Concerned with engine life expectancy and cost of a new engine.

is it carbureted or fuel injected? are your warning horns working? if it iscarbureted then a few easy test can be done to find out. if its fuel injected then its a little harder but not impossible.(1) check compression. without the year model I'm giving you a average numbers. all cylinders need to be over 100 lbs and equal each other within 5 lbs.(2) check spark. use a spark gap tester all cylinders should jump a half inch gap. if you have good compression and good spark fuel is the problem nine times out of ten. clean fuel lines replace primer bulb and replace all fuel filters. Yamaha has a gravity filter under the engine coul. take it to the lake if no improvement. clean carbs. same test to be and fuel system service used of fuel injected engines. if no improvement in engine preformance then you will have to take it to a dealer to test with computer.

On the tachometer back you have secured a wire thread just like the one from the brakes of a bicycle. The other end of the wire is secure to the engine. This wire complete, need to be replaced. As a test first disconnect it from the tachometer and see if ok if not then the problem is with tachometer.
