Im looking to repower my boston whaler montauk.I have a local dealer who has a brand new 2007 suzuki still in the crate.Its hard for me to put a value on a 7 year old motor ?) Not to mention if it would be a good choice for my boat with has a 90 on it now.Once i walk out the door its a 7 yearold motor new or not new.Also were there any changes made over the years to the 70 that would make a big diffrence.....Thanks for any input
