Just to inform everybody in case you have the same motor.
My motor is a Yamaha 200VMax carburatted 2002 model which i have from new. The motor has done 426 hours in total.
So far the only thing I have done is to change the anodes in the cylinder heads and of course regular services as per book manual from the Yamaha main dealers in Greece.
However, after 426 hours exactly the following have been noticed:
1. White spots floating in the gear box lub oil. Which according the the mechanic means that I need new gear box gaskets.
2. When you bring the pistons in the top position and if you take one spark plug out and you press with a screw driver on top of the piston from the hole, the piston retracts by about 2-2.5 mms. This means that the pins have been warn. The engine must be opened, and pistons, rings, pins must be changed, new gaskets and all that. In case there is a damage in the cylinders, the block needs reboring and bigger pistons obviously. Someone told me that may be the crank shaft may have been damaged too.
Cost for all the above including the oil floater of the main oil tank, gaskets (all Yamaha original), and full piston kits (after market) all coming from the US with shipping is USD 952.75, labour costs in Greece EURO 600, if the cylinders need reboring have to add another Euro 30 per cylinder = Euro 180.
TOTAL in Euro 660 + 600 + 180 = TOTAL Euro 1440!!
The question is the following:
1. For the gear box, I understand that this may be considered normal wear and tear
2. BUT for the engine, is this considered normal to have such a damage to have such a damage? Is this repair necessary? (I believe that it is). Is there any chance that the crank shaft may have a damage too?
I know that will find all out when I will open the motor (mid next week), but I am just asking to be prepared for the worst!
