Hello all!

I am new here and looking to enhance the performance of my 2002 23ft Caravelle Interceptor. It has a 260 hp version 5.7 liter. Or as Volvo marks it 5.7 liter GL. I would like to change the heads if needed, cam intake combo to make 350 to 400 hp. I am unsure what heads are on the motor may be vortec. I understand building car hp a little better but realize boats are a little different. Also I have captains call and do I need to change exhaust manifold. Any help would help. I really need some guidence. Please dont assume I know a thing!!! Thanks for help

whirl-away question.

2 hours 56 min ago
I have casale v-drive with a whirl-away on it but I think its going to only release if the prop shaft was to spin right hand. The motor is in back wards, driving off the fly wheel going in to the v-drive. If I hold the input shaft and try to spin the prop shaft to the left it wont release,but if I hold the input shaft and spin the prop shaft to the right it releases. I'm guessing the whirl-away could be for a motor if it was being driven off the front of the crank but i'm still learning. I mite be over thinking the whole, I hope I am. if this helps the motor is a BBC. thanks.

Any Big Cat Throttlemen/Drivers here who've flipped by the boat pitching up?

4 hours 50 min ago
Any Big Cat Throttlemen or Drivers here who've flipped by the boat pitching up? If their are any here, can you please discuss at what moment you knew you were going over and there was nothing you could do? What I'm looking for is an estimate of current position of the boat. A picture or screenshot of a video of the angle of attack of when "you knew" would be worth 1,000 words doesn't matter what boat it is.

I have a concept that gives pilots an "out". I'm trying to determine if it's feasible or if it's already too late by the time the pilots realize it. Thanks.

GPS android apps?

11 hours 5 min ago
I was on the river lastnight after dark and there is a section of my trip that can get a little confusing and difficult to navigate with several hard to see and underwater obstructions. That got me to thinking, are there any Android apps that allow you to plot a course and mark stumps etc. and then show you realtime a line to follow? And if so, any recommendations?

Thanks, Todd
