High sodium is a big red flag and shouldn't be taken lightly.

On my Pilot 34 I got the oil analyzed after I bought it and trucked it home. Hi sodium- 700 ppm. Should be less than 10 ppm.

I concluded that the travel lift operator raised the stern first and allowed seawater to slosh forward into the engine from the exhaust. Or the truck's starting and stopping sloshed it forward. There was no exhaust turbo corrosion or rusty valve train so the sodium hadn't been there long.

I reworked the exhaust to add another 8" of height to an existing 8". Spec is 12" or better. I also serviced the after cooler.

So look at your turbo outlet. It is easy to do. Remove the insulation blanket and loosen the clamp on the turbo exhaust piping. Look into the turbo throat. It should be clean, no roughness with only a light soot coating. Any roughness or rust indicates seawater ingress.

Or it might be a leaking air cooler letting sea water into the air stream, and a rusty valve train is an indication of high sodium being in the oil for a long time. But I would put my money on the exhaust. I don't know how much clearance there is for a fix on the Pilot 30. Mine had enough room to extend the dry riser 8".

PM me and we can discuss.

Congratulations on a great purchase. I also agree on the great color choice - but then I'm a bit biased that way. May you have many great trips with her.

I agree...but white is very practical.

The worst color we use to see on the lake was a silvery grey. At dusk, those boats became almost invisible.

Then there are most of the sport boats like Riva or Sunseeker or Pershing, and it is what it is so you just accept it. Oh and on those, since they're mass production boats, generally not an interior choice either.
