    Very helpful. Thanks. For reference I see approx 60psi at idle when dead cold first start. But that drops way down to 25 when warmed up. Testament to letting an engine warm up before doing WOT.

    Update. I've run a full tank of fuel through and the ski is running well. 7450 RPM/14 PSI/64 mph on GPS. Only a couple of issues I still need to address: (1) small water leak from the exhaust manifold, and (2) cavitation on a hole shot. I ordered a rebuilt stock prop.

    I'll pull the exhaust manifold and install a new gasket. I had to reuse the one I had with copper spray as I changed out the manifold due to a busted bolt. I didn't have a new one handy, but won't make that mistake again.

    I also ordered the CandooPro GPS module, which as I understand will also remove the limiter.

    It's a really nice ski, strong acceleration and corning, pretty smooth in mild chop. Ski is super clean, freshwater and had <100 hours. It sure drinks fuel at full throttle!

    What I did:

    - Used 310 case and crank
    - Used 300 rods (thanks @grumpy_stephen)
    - New windage trays
    - New rod bolts/nuts
    - New piston rings
    - New piston pin snap rings
    - New main and rod bearings (plastiguaged)
    - New supercharger belt
    - Cleaned and spray tested injectors
    - New supercharger intake pipe (flange was broken)
    - Used exhaust manifold (due to broken bolt)
    - Lapped all valves and checked valve lash
    - All new gaskets
    - Cleaned intercooler
    - Tested oil pressure relief valve
    - Tested oil cooler thermostat per shop manual
    - Checked pump bearings
    - New Iridium spark plugs
    - New Odyssey PC625 battery and Battery Tender

    Might keep this one for a while. Though, I let my buddy in the neighborhood ride it yesterday, and now he wants to buy it.
