Looks great Sheldon! Well done. The local F/FC-470 chapter needs to meet up soon!

We are running out of time to meet up on water. Although I did take mine out yesterday. Got a little chilly after sun set.

Yes, it did get chilly yesterday after the sun went down! I was out in the afternoon on both Saturday and Sunday, Saturday felt a lot warmer.

I got the boat up to 30mph per my GPS, first time I've properly clocked it. Next season I'll have to get a tach and properly measure whether I've got the right propeller on the motor.

30 is pretty good what pitch do you have? Should be stamped on prop.

12 1/4 x 15.

Bigger diameter than most of the charts suggest and plenty of pitch. I got 30 on light chop with two people on board, all the way to the rear of the boat to manually trim the nose up as much as possible. Under smoother conditions with a more balanced load it slows down to around 25mph, and I suspect the RPM's are lower than they should be at WOT.

Don't have a tach yet, so not totally sure.

Sheldon. Where the valves hard to disassemble? Did you rebuild them? I had mine rebuilt at IBC but I suspect two of them are leaking.

I'm no Sheldon. "rebuilt" is pretty much in his pictures. Take apart, clean, inspect, lube , put together. I did same thing to mine. One of valves was missing washer/sprint retainer. I would only add: when taking apart position valve in Navigation mode. This way if you drop a nut or washer it won't fall into one of those openings.

Does yours seal correctly or do they have to be in a specific position in order not to audibly leak air? My port side valves need to be in a specific position marked by a permanent marker in order not to audibly leak. My starboard valves don't. Is this normal? Will a rebuild fix my port side valves?

That sounds normal. I don't have an FC470, but I've had older Grand Raids that had intercommunicating valves and they all did that.

If it was normal wouldn't all 4 valves behave the same way then?
