I am buying a boat with twin 454's that have compression readings that vary from 125 - 140 on both engines with 750 hours. Are these readings good? average? bad? I appreciate your help. |

Bruce read the last post on this topic and it will give you the information straight out of the Crusader Operation and Maint Manual.

I'm about ready to purchase a 1988 370 C. C. Amerosport. Does anyone have any information about what to expect or what I should be looking for on a boat like this? Are there any inherent problems you may be aware of? |

Bruce,
To me those are average readings.If they were taken when engine was warm,all plugs out and throttle open, they will be higher than on a cold motor one plug at a time.Might want to see how old the manifold and risers are before purchase.Surveyer should lead the way for you...Todd |
