I am trying to sell a boat that I bought new in 2007,the motor doesn't even have 10 hours on it . I broke it in the way dealer told me too. when the buyer wanted a compression test done on it by his dealer the test came up low compression (#1 cylinder came up 150 #2 190 #3 190 #4 190 . It runs so nice and never had any issue? is this possible. they say a leak down test was done on cylinder #1 and it cam up 60% leaking . The warranty ended last July. Is Yamaha just a junky motor ? or does this sound fishy?and if this is real what kind of expense it this to have someone fix it?
