1998 Yamaha Saltwater Series 225

[captain537]

Hello<br />I have a 1998 Yamaha 225 with 950 hrs on it.<br />I didn't know until recently that there are 4 internal zincs inside the motor.<br />I have never heard anyone talk of changing the internal ones.<br />Do they neeed to be changed and where are they located.<br />I am the original owner, I de-carb the motor every 75 hrs or so, change the zincs every year, use ring free all the time and only use Yamalube.<br />It runs like the day it was new........knock on wood.<br />I have one other question, can anyone give an idea of how many hours I can expect to get from the top end.<br />I am a firm beleiver that going the extra mile with maintenance and regularly de carbing the engine and frequently cleaning the O2 sensor greatly extend the life of a 2 cycle.<br />Thanx for your help<br />Bruce
