I'm looking at an 89 model champion with an '89' 150 Yamaha on it. The dealer faxed these compression numbers over to me. Any input on these numbers or the motor in general?
#1 - 115
#2 - 115
#3 - 115
#4 - 110
#5 - 110
#6 - 112

Those are good numbers Joel as they are all within 10% of each other.
18 year old engine...be careful! How clean are the cylinders and piston crowns? Are the fuel pumps and fuel lines relatively new?
I haven't had a chance to look at anything...this boat is about 5-6 hours from my house, and I just found it.
I'm not sure I will proceed with anything, actually would like the boat with a new motor on it.
Really want to know if anyone knows what the compression would be new, or rebuilt to see if how far these numbers are off.
