My brother in law has a 427 in his jetboat that has roller rockers in it. He says it has a knock or tick to it and needs advice on what is going on with it. Oil pressure is good power is there just a knock or tick. We are in santee, ca if anyone knows where to take the boat or if anyone out there is near to us that might be able to check it out that would be great.
Thanks in advance for the help as you all have helped out in the past.
