hi all<br />i just came back from looking at a 1990 johnson 40 vro model# CJ40ELESR. owner has receipts from new. smoked a fair bit but was told that was fogging oil from last fall. he said this year hp was taken at the prop, making it equivalent to an older 55 hp. any comments on this motor are appreciated

It is a good engine. The basic design has been around for eons.<br /><br />Don't buy until you do the following.<br /><br />1. Look at the lower unit fluid. Make sure it does not look milky.<br /><br />2. Compression? Both cyl's. should be real close to each other.<br /><br />As far as the HP thing goes, he is right, that engine was rated at the prop. As far as it being eqivelant to a pre 1983 55 hp, that's a stretch. A 45 hp.- maybe.<br /><br />Typical gear train loss in an outboard is around 10%. Ratings have to be within 10% of the rated hp. Thus that engine could be as high as a 44, or as low as a 36.
