Breeze how many hours do you have on that power head. It should be a little higher then that. It might need a good decarb but with them being that close it seems more like wear to me but a little more info like the hours used on it will help dertmine this closer.

hey bubba how high should the comp be. i dont know how many hrs are on the head. it was done before i bought the boat a year ago.

can someone tell me what my comp should be on a 90 200xp evanrude engine?

Breeze, anything that is even is good but anything above a hundred is acceptiable. I like it when they are at about 120 or better. It really depends on the amount of hours on the motor. With what you go it will run okay but will be a little harder to start. I would do a good decarb and it may bring them up another 10 pounds. But don't get to flusterated just yet there is still some good life left in the old gal. It will need to be kept tuned real regular to keep it where it will start good.
