A question for all the Yamaha mechanics. I was running my boat the other day when I noticed my rpm' started to drift down. Lost about 400rpm when I figured something just wasn't rite. I had no alarms or anything else. When I came off plane I looked back and noticed a cloud of white smoke so I killed the motor asap. After being pulled back to the launch I pulled the cover and I noticed oil had blown out the throttle body. The shop did a download, a compression check, and a leak down check. All this info has been sent to Yamaha and I'm waiting to hear back. The shop did say the motor was tight when they had to turn it for the leak down test.
Any thoughts? Thanks to all.
