    1390 Finally Sees Water

    Beautiful day at Senators. Weather mid 80's, reservoir full and glass, NO WIND!

    The 1390 hit the water. There are still a few bugs to work out. It will be about three trips before it is dialed. Saturday afternoon was breakin. Just riding around looking for water leaks etc. After about two hours and all the cool down shiz I gave it a run sitting on the seat. 75.5 fat as hell 84 6940 rpms. The ported 1300 did 79.3 @ 7280 with a setback 14/24.

    6 a.m. this morning the 1390 pulled 79.7 at 7120. The 145 mains are too much on the Black Jack 48's. I'll put 140's in for the next trip out. Ski runs good. My intermediate shaft is leaking water into the hull and my gas valve springs need tightened a little. I noticed some bogging on a right hand turn trying to accellerate from a low speed. Not so much on a left hand turn accellerating from a slow speed. So a little more work and she will be getting close. The ski started to hop just like the 1300 used to at 79 mph so some holes and plate adjusting are in order. The impeller is a set back Dyna Fly 15/25.


    The 1300 went 3 seperate back to back runs 80.2 twice and 80.3 once. It is under propped. I was turning 7360 rpm's. The conditions were as close to perfect as possible. The ski needs a 15/25 back in it. I am waiting on word from Solas before I get anymore bending done. The ski was absolutely solid at speed no sign of hopping. Thanks again Joe and Woody.

    All said and done it was a good weekend. Nothing broke, good numbers and some more tinkering needed. I like to plan out changes or adjustments.

    Thanks. I plan on doing the work over Thanksgiving weekend so won't be too much longer before the next trip. It will take a few more trips for the carb set up.

    Right now its Black Jack 48 (modded stock carbs)

    Highs 145

    Pilots 115

    N&S 2.0

    Black springs

    Low speeds 1 1/2

    High speeds 1 1/2

    For the next trip I'm only going to change the mains and turn the powervalves in. I'm running the red springs on them.
