  5. V-Drives
    I just installed my new 18’s in my Casale, but the only way I could get them in was to put them in backwards (by that I mean not being ableto see the stamped numbers on the gears). Does this mean I put a set of RH gears in my LH drive boat? I can’t see it making a big difference either way, due...

    Curious if anyone is running any LS motors in their v-drives, wanted to see what the feedback was. (good or bad) I know they can make big power with different power adders. Thanks

  8. Outboards
    OK, maybe not performance but who cares. I have a 9.8 I believe to be an 80 or 81. Unknown origin. I ran it one day, ran good, hard to start, poor water flow. Replaced impeller. Pretty good flow... still not steady stream, but will get full kit and redo. Replaced spark plugs and properly gapped...
  9. Jet Boats
    I have read a lot of conflicting information about running a jet out of water. Is it acceptable for the boat to run for a few seconds without water to the pump? If there is a hose spraying thought the intake of the pump is that sufficient for short amount of run times? I know the engine needs...

  12. Jet Boats
    I've heard it said several time that its bad for the pump to run the boat out of the water, My question is how bad? If I ran it for 10 min "dry" should I redo pump. I commonly fire the boat up on the trailer right before putting it in the water just to make sure its going to light off, is short...

    Gotta say Phoenix was great. But most of all , I really enjoyed seeing some real quick jets running low MPH. DeClark running 6.05 @ 114 mph & 6.07 @112mph Starkweather running 8.02 @ 122 mph And that's barely bumping the spray to run the number. There's no telling how quick these boats would run...
