    Tell tale signs of salt water use?

    I'm looking at buying a used 210. The dealer just got the boat and claims that it never has been in salt water. I saw it before it was detailed and all the running gear have a green tinge to them and the hull has some dark raised spots on it. I've had my current boat on my lift in fresh water for 6 years and never has seen green tinge on the running gear or the bumpy stuff on the hull. The engine is a zr6 if that makes any difference. Thanks.

    They may have just had it in a marina with no lift. Just check everywhere you can for rust. Otherwise you either have to go with your gut or trust the dude. Sorry, I'm sure that wasn't much help

      I know this sounds wierd, but I would open the inspection plate for the prop shaft, run my finger around the seal and touch it to my tongue. Is it salty? if so the boat has been run in salt at one time or another.

        After I cleaned my hull with ON/OFF, the running gear turned green and ugly and my boat has never been in salt. How old is the boat? I would think rust is the biggest indication of salt water use. Since the ZR6 motor has closed cooling, it wouldnt show up as easily. I would inspect the trailer closely, though.

          If/since the ZR6 has closed cooling system, then what does it matter if the boat has been used in salt water absent of any hardware rust. The main issue with salt water is internal engine corrossion...but with closed system, this is a moot point.

            Not necessarily. You still have to worry about the exhaust risers, which rust out even in fresh water. Cooling for those is raw water, whether you have closed cooling or not.

              RE: Re: RE: Tell tale signs of salt water use?

              If it has a ZR6 then it's a pretty new boat. Even if it was sitting in salt water for a few seasons, it might still be ok. But how does the dealer know that it was never in salt? Do you know where the previous owner comes from? Is there fresh water around there? Is it coming with a trailer and if so is it rusted or galvinized? Some good questions to ask...

                Just because it has a galvinized trailer does not mean it see salt use. I have a galvinized trailer and refuse to drop mine in the salt.

                  No it doesn't, I would be wary of it, especially if there were other evidence of salt water use.

                  So, why do you have a galvinized trailer?

                    What does it matter?

                    Why do you have 18 lights all over your trailer?
                    I don\'t care.

                      Good point, forgot about the exhaust manifolds. However, if the rest of the boat is good, then manifolds are relatively easy and cheap to replace.

                        My dad has a '79 Invader Tri-hull with an '80 115 Envader. His has galvanized trailer under it that is a '79. It is in perfect condition. I have seen painted trailers that are 5 years old that have never seen salt and need replacement. I did not want to be replacing my trailer every 5 years.

                          Understanble. My original '82 trailer rusted a little but had more axel problems than anything else. So in 89 we replaced it. THe boat however, is still going, and going and going....

                          That said, todays trailers are certainly painted better than those old ones and might last considerably longer. I'll let you know....

                          BTW, i actually do want to put my boat in salt water, but don't want to risk the $4500 trailer! So could I borrow yours for a day? :grin:

                            Sure, come on down and pick it up, but at fuel prices these days, it might be cheaper to just buy one locally or have your trailer dipped. In truth, it would be cheaper to have yours dipped than the cost of fuel from NY to TX and back.

                              I only want to put it in salt once or twice a year. I was thinking of asking the marina to launch it for me using one of those humongous slings.
