I have a 1973 18' Sportscraft with a 1970 115 HP Johnson OB. My mechanic (who I trust) told me the compression was low on two cylinders and recommended replacing the motor. He has a 1994 120 HP Force which he'll sell me installed for $1800. Is this a reliable motor, a good price and will it provide similar power as the Johnson?<br /><br />Thanks, Kevin
