I have a 1989 Force 125HP on a Bayliner Trophy. One motor only revs to 4000RMP at full open. I checked the compression...#1-120PSI. 2-130PSI 3-120 PSI 4-100PSI.<br />I did a wet compression (oil in cylnder) #4-went to 130PSI.<br />Question 1) What is the most likely cause Piston rings or Head gasket? or other possibilities?2) Can a back yard mechanics replace rings?<br />3) What would the parts cost from Iboats?<br />4) How many hours would it take a professional to do the work?<br />5) Will it cause more damage if I contnue to use it as is?<br />All help is greatly appreciated.<br />Jim
