looking at buying a 2000 pursuit 3070 powered with twin 2004 Yamaha 225hp four strokes.
i'm new to the whole 4s engines.
I had the marina send a guy (@ $200/engine) to test them:
PORT MOTOR STBD MOTOR
CYL #1= 175PSI CYL#1=175PSI
CYL #3= 175PSI CYL#3=175PSI
CYL #5= 175PSI CYL#5=175PSI
CYL #2= 165PSI CYL#2=150PSI
CYL #4= 165PSI CYL#4=150PSI
CYL #6= 165PSI CYL#6=150PSI
"THEY JUST CHANGED OIL IN MOTOR SO I COULDNT
SEE IF ANY DEBREE SO IF U WANT WE COULD GET A OIL SAMPLE
AND SEE IF THEIR IS ANY WEAR BUT BEST KNOWLEDGE COMPRESSION DIFF.
MIGHT NEED VALVE JOB . I HAVE SEEN THEM WITH 35OR 50 PSI DIFFERENCE AND
STILL GOING . IF YOU HAVE ANY QUESTIONS FEEL FREE TO CALL .THANKS"
I have asked him to do a leak down test but is it worth it?
they have 750hrs on each.
I think I'm going to send someone else there? and words of advice would be appreciated.
Thanks,
Colin
