I'm helping a friend who's looking at a number of boats, including 02/03 Johnson 70s. The one we looked at today seemed to be very nice... the aft deck and platform is huge for such a boat yet it doens't come at a high price. We poked around quite a bit and found a few minor things, some to look at closely during survey. couple of questions though... How good are the 1400hp C18? some c18 appear to be rated at 1000hp, we're afraid that 1400 maybe pushing it a little too high? engine survey will help, but those engines have close to 1000hrs on them. how about the 1300hp MTUs? about construction... the stringers seems to be hollow (from taping and feeling around in some limber holes). how solid is the construction? solid glass or cored below water line? We also saw a streak next to a bonding bolt (under the master) indicating less than ideal sealing. hopefully, this is a solid glass bottom! ER is a little tight but manageable... altogether the boat has few "what-were-they-thinking" issues on it, although i dont' like batteries (even AGM) in living quarters and locating the shorepower plugs on the bottom step on the swim platform ins't very bright... any feedback on these boats is welcome!
