    Default At What Speed....

    At what speed do you run a real risk of getting tossed or at least digging the nose if the engine dies? My old Tahiti did not have a loader only a rock grate nor a shoe but it never did over 55 so you could lift off the pedal at full speed and it would coast straight. My new gullwing will have both plus more speed so i was just wondering. I plan to have my kids in there and don't want to take chances with them.

    Depends On Your Setup. Im Sure All Hulls Are Different. I Would Just Get A Good Baseline Setup And Get To Know How She Handles.

    How Fast Will You Be Running?

    Not sure to be honest. 468 with an "A" impeller, tapered shoe. At these altitudes, 75-80? I know set up has a ton to do with it and i definately will take it easy and learn the boat by myself. Just curious at even moderate cruising speed 35-40 mph which is as fast as i would go with the kids if there is it still a possibility? Anybody run a gullwing similar that can give an idea?

    The 19 gullwing I used to own shut down at about 80 mph once. I was running the shoe about a 1/16 above keel with a loader that had ramps slightly below keel at the time. It slowed pretty hard but no where close to being tossed and it went nice and straight.

    Default jet-a-way

    it doesn't really matter what anyone tells you... there is always a possibility of getting tossed out and going for a swim... it sucks but thats the cold hard sad truth about our hobby/sport of boating. if the motor shuts down (for whatever reason, God forbid it happens) a jet-a-way is probably your best bet. regardless of set up... just remember if you run a jet-a-way. always keep it in the drive position unless your doing a "warm up" on the motor (then it will be in neutral) then quickly set it back in drive. its a good habit to get into. that way the springs in the jet-a-way dont go soft and it will work when you need it to. (God forbid you ever have to use it in such a fashion) my brothers boat shut down on him at about 70mph... said it scared the S#*T out of him lol the set down real nice and easy just like he was coming into a no wake zone and he said could hear the jet-a-way "ratcheting"... he simply slid it back into the drive position and off he went (carb loaded up on him) said later, it was a great feeling to hear that thing after having to change his shorts so to speak!!! its a small price to pay, $1500 or so, but a life is priceless!!

    Its a new engine so I don't know either of those. I figure max 480-500 hp and 5200 rpm. Just a guess from what i've heard on similar set ups. Pump gas, no nirtous, naturally aspirated.

    I have never owned a winger...but you made a good choice steppin up from the tahiti. My tahiti was fine at 55 at 70 ish gettin off the throttle was interesting at times. I love my tunnel..I feel safe with my kids at 75 ish....thats all my boat is good for at 4000 ft.

    I have a pretty conservative setup in mine with gobs of power and if I let off the gas too fast it is like I slammed on the brakes. So even a safe/conservative setup isn't safe at high speed. It is definately not safe to do but if it were a failure at speed then the jet away should take over. That being said it still goes straight and true with no thought of hooking. then there is the possibilty of a loader breaking. We have heard it in the past ans I know of a handful of guys that it has happened to lately. For that reason alone I would be worried in a gullwing. I run the lower river almost every weekend with my family (2 kids under 5) and when they are in the boat I never take the boat over 3500 rpm which is roughly 40 mph. If your loader breaks even going that slow you will have cause for concern. My best advice would be to set it up how you want it to run (safely) and be safe with the fam in the boat and most importantly check your loader on a regular basis. Do not use stainless bolts (only brade 8 black oxide back up with a nut in the bilge) and paint it white so that if a crack appears it will noticealbe right away.

    With the old set-up yrs gone by I could side-step the throttle at 90 mph boat would just glide to a stop. The shoe was anywhere from an 1/8th to 1/16 up from the keel.

    Totally depends on the set-up of the boat.

    This was an point of conversation way back in the HotBoat days. I never had a problem running stainless bolts ran them for yrs. Checked the intake every afternoon the boat came out of the water.
