Hello<br />I have a 1998 225 Yamaha Saltwater Series.<br />I did a compression test with the motor warm, and sprayed deep creep in the cylinders before each test.<br />All 6 cylinders were 105-107. I know it is good when they are all close to each other, but is the 105 range good for a 1998 Yamaha with 1300+ hours on it?<br />One other thing I was wondering, based on the experience of this forum what is their best estimate for life expectancy for 225 outboard?<br />What is the most hours you have seen on a hour meter when it was time for powerhead or rebuild?<br />I have always used Yamalube ( despite all the oil conversations on here LOL ) and always use carbon guard ( will be using sea foam this yr tho ) I decarb the engine thouroghly every 100 hrs and clean O2 sensor. The motor has never been over 5000rpm and rarely goes over 4600. At 4600 with 2 people on board I am doing 34 mph with a 25 ft cuddy cabin.<br /><br />Thanx guys<br />Capt. Crunch
