COMPRESSION READINGS
(top to bottom, where is #1 cylinder?)
------------------------------------ 3 complete
1st full compression stroke.----- revolutions ------------------ max build up, 5 to 8 revolutions
25 -------------------------------- 105 ------------------------- 150
40 -------------------------------- 105 ------------------------- 150
50 -------------------------------- 90 to 105 ------------------ 125 to 135**
40 -------------------------------- 105 ------------------------ 135 to 145*
40 -------------------------------- 115 ------------------------- 140 to 147*
30 to 35 ------------------------- 100 ------------------------- 140 to 150*
What do you guys think about these readings?
I checked each cylinder around 8 times & went over them twice, very consistant with these readings. the astrik readings were the most inconsistent & not by much.
Also I can not find the id number plate on the engine I think it is missing, the boat title has an engine number on it & comes back as a 1972.
It needs a wire harness, stator, fuel line from pump(s) and the normal stuff from sitting .
