Sitting at the dock surveying boat twin 1350hp engines running for 30 minutes and at 1250rpm for last 15 minutes. The following conversation..
Surveyor " ok take her up to wide open "
Me " What "
Surveyor " Open them up, put them on the pins "
Me " for how long "
Surveyor " 15 minutes or untill I tell you to slow them down "
Me " Get off my boat "
Surveyor " Your going to fail the survey I have to test the engines "
Me " Go survey someone else's boat "
Anybody else ever heard or done this? I felt stupid like I was missing out on something, but I wasn't going to try it.
He wanted you to run them WOT for 15 minutes,,,,, in neutral??? WTF,,,WHY? Those engines would be SCREAMING at the Governors at like 2500+ RPM with No load on them. Did he give you a reason why. That just doesn't sound right, or good in any way. I've seen Mechanics test no load RPM for a few seconds just to see if they'll turn up and it sounds scary as hell to. 15 minutes? I wouldn't have asked him to leave I would of tossed him.
I don't even like the way motors sound at Full throttle under load at sea. That's why I'll do WOT only every so many trips just to make sure they'll turn up and maintain a safe temperature but after a minute at most I bring them back down to Cruise RPM. I'd say a minute is pushing it, usually only for a few seconds once they hit 2300+ RPM. It's only occasionally that I'll hold them there a little longer to watch the temps and I HATE Doing it.
15 Minutes really,,,,, maybe you heard him wrong. I still can't believe it.
Also Jack, when we purchased ours the surveyor made a big deal about the blisters also. Most were gone after we returned from lunch and any bigger ones that remain and happen to open up during the sanding for a bottom job we have repaired. Any surveyor that doesn't know how most of these old Hatteras have some small superficial blisters makes me wonder where he's been and how long he's been doing this. He kept harping about them before we went to lunch and I told him I bet most of them dry out. He argued with me, I was right. He never admitted it or brought it up again.
