need advice on used outboard purchase...

[bsteckel]

here we go again ... am on vacation for the next 10 days in DE ... located a 98 yamaha 150, oil inj. saltwater series motor. guy says he bought 2 motors as a pair .. approx 450 hours. installed this one on his boat. he could not get the motor to spin up past 3100 rpms or so .. took off carbs, cleaned them .. tried again .. no go. changed fuel pump ... again no go. i think he even replaced the carbs and still no high rpms.

so then he gave up and put the other motor on that he got and it worked great. so now this motor is for sale. says he checked compression and all were 98-115. he says that is all he can tell me. he gave up and put the other motor on .. then this one went in storage. did not have the time to fool with it.

motor looks real nice externally. not sure what else could be the problem. he said he can rev the motor up past 3100 by hand, but when motor is in gear .. no go.

does this sound like something i should walk from or maybe this could be an easy fix .. not sure what there is left to try.

thanks
