Motor decisions.....

So on my '89 Pirata project I'd be better off with an auto 6.0l? Are marine add on components around such as reasonably priced exhaust available?

Sorry Haugy, sarcasm just flows out of my like pee after a long day on the boat. not planning on repowering yet, but if i blow it up by accident when im hot lapping, i'll definately consider a modern fuel injected power plant. id love to cut my fuel bill by 20-30%. BUT..... if i go through the trouble of repowering, do i really want to put a "stock" engine back in? A cam, intake and software tuning would be in order. There goes my fuel savings lol...

Well, considering a Gen 3 6.0L is about 350 HP and 380 ftlb tq and its lighter than a 351W, and especially a 454, I dont think you would need a lot of extra performance...

Just putting a free flow intake and exhaust lets the LS motor gain some power, so, Marine headers, big air-filter, and a cam, you would be more than set...

I think it's funny how some of us with larger boats (Saltare/Pirata) are concerned with how much the engine weighs. How many of us got these 23' behemoths expecting a great slalom wake? If you use it primarily for wake sports lightening up the engine means you'll just need to add more water and these boats don't exactly have a ton of hiding space or room under the floor for bags.

Great point cadunkle, i never would have considered this.... keeping my boat anchor 454 is like having a 250lb bag already filled.

actually probably more than 250 lbs, considering the LS motors weigh less than the 351W as they are Aluminum heads and block with plastic intake. And the 454 is just over 200 lbs more then the 351W, wouldn't be surprised if its a 300 lb+ difference....
