#2 cyl low compression CABREA 75

[rbcj7]

eng lacks power. I did comp ck. #1 130, #2 30, #3 130. squirted oil into cyl #2 comp 90psi. i figured i'd rering the motor. is this a tough task? can the average back yard mech perform this? Can't afford a new power head or pay big bucks to have this done. (kids in college)

depends on if it will come apart. is it a salt water motor? most likly its scuffed a piston. you will need to find and fix the cause of the failure while your at it..

Fresh water motor, pulled the t-stat out and no corrosion on the bolts or cover so i figure this should come apart okay. This is my first outboard, so i was gonna pull the head off and if the cyl walls looked okay i wanted to rering this other wise i'll toss it and get another motor.

that motor is very easy and inexpensive to rebuild. use the service manual and have the rod big end play tested. if its ok bore the offending hole add a piston or all 3 and go play.

Thanks for the confidence builder rodbolt. I'm gonna order a manual and tear it down.

I reccomend reading the manual a few times before starting, higlight the parts that will pertain to your objective. also rebuild/repair fuel pumps,water pumps carbs and fuel and oil filters. replace the inline oil pump check valves and any hardend vynil tubing.<br /> and a note book with a digital cam and a box of 1 gallon ziplocks come in very handy.
