Compression on Volvo Penta

[Diver503562]

My cousin has a 26' Coronet with a 5,2l VP V8 engine, 225HP. (Don't have a ser.no now..) He is having problems with power loss. We have done a compression check with following results: 128,135,125,132,132,124,136,131. Can anyone tell me if this is good? Or are the readings low?

not terrible unless 124 and 125 are next to each other. adjacent cylinders low and even can indicate head gasket blown between the two.
