on your boat share...... on mine NOOOOOOO. lol lets hope it is some thing on the top end thats causing it because was planing to do them any way.... bought the boat with 345 hours and on about 15 or 20. didnt run as much trying to recoupe form buying the boat. with having near 20% leak down on some cylinders should i just go ahead and have them pull the heads any way and have them checked and new head gaskets a car guy told me that if the leak down is good just do the springs.

See what you find out this weekend. At 345 hours that motor should have a lot of life left in it. The leak downs at 20% when cold are not that accurate, but a good indication of no major problems. If you do anything with the heads, because you are half way into it, I would pull them to change head gaskets and do a quick valve job and springs to start off fresh.

i mainly wanted to do the top end becouse merc has it to be done every 300 to 350 hours. pluse with buying used its better to be safe then sorry. u never know how the outher guy drove the boat, he keept it mint and only put 324 (now that i looked back) hours on it in 11 years. but thouse could be hard hours.
