Hi everybody, new member here, I have been looking to buy a 203-2007 BF225 to re-power my '93 236 Coastal, I came across a 2005 BF225 ex-USCG, they guy says that he does not know the hours but I'm sure it has a couple of thousand on it, engine looks really clean, no rust anywhere, no rusted bolts, it looks like it has been very well taken care off, starts right up, idles fine, the green light on the ignition switch stays on.
I did a compression test on it, I first let the engine warm up, then removed all the plugs and check cylinder by cylinder, compression was about 180 to 195 PSI on most cylinders, but....cylinder #5 had a bit less than 175 PSI and cylinder #4 had the highest number of them all at 195 PSI.
I know on two strokes if there's more than 15 PSI difference in between cylinders is not a good sign..but I do not know if that also applies to 4 stroke motors, any comment or input would be greatly appreciated, thanks in advance for your help.
