    Advice on adding closed cooling to 5.7 GSi

    Howdy everyone! I hope the summer is treating you all well so far. After finding water in the cylinders and pulling heads to find quite a bit of corrosion in a motor with close to 1,000 hours we have decided to go ahead and replace the motor with a rebuilt stroker and new heads while i've got...

    '99 VP 5.7 GSi - PWTR continues to overheat after running w/o water line hooked up

    Howdy everyone, long time no see; as you may surmise the boat has been running very well until lately. Took the parent's '99 Four Winns Horizon 240 out for the first time of the year and noticed the power steering cooler was leaking water while running; I'm sure it was due to not being properly...

    Check your U-bolts

    Towing the Four Winns H240 down I-20 last night when I ran into a bit of a problem.

My first thought was that I had jumped off the...
