What speeds are you hitting?I'm, as usual, late to the Four Winns jetboat party. I have a 95 FW H190 w/ the Redline 351 and AT jet drive. My rear floor plan is way different than your 96 but from midship forward it's pretty similar. I don't get anything close to 50MPH on the water.
You can trim your jet output? That's bad ass! Mine is fixed. It used to have some semi factory looking trim tabs attached in the far rear of the boat where there's no support structure. I (accidentally) tore one off so I removed them and just added the Nauticus Smart Tabs down and attached to the transom directly.
Got any photos of the jet drive? I see yours has a second cable running to the top side, I'm assuming that's the 'trim' adjustment.I'd LOVE to trim it down just a little to reduce the jetwash at the surface!

I zoomed in on one of your photos and yea, looks like a diverter that goes inline to trim up and down. Is yours powered or manual? What's the controls inside the boat look like?Yes I can. Don't have any more pics of jet. It's in the water or I would gladly take a few for you.
I'm pretty sure you can add the place diverter so you can trim but not sure how expensive it would be.
I honestly haven't pulled any tubers yet. Have left the dock to go tubing only for the sheriff to pull on lake 3 times so I just pull back out. Not really a high demand since am at a camp ground where everyone has a boat and the kids are always tubing with someone I'll see how it goes this weekend. I have read about the problem you are having and most recommend extending your rope 10-15'.I zoomed in on one of your photos and yea, looks like a diverter that goes inline to trim up and down.

I gotta do some research to see the option(s) of adding that. I thought about adding a droop snout to see if that lowered it just enough to change the aerated wake. The center of my wake is so bad that at tubing speeds you feel like you're in a rain storm riding a motorcycle without eye protection. It just plain HURTS! Swinging the tuber thru the wake from side to side is fine and getting them outside the wake is smooth riding but first time and inexperienced riders are tough to tow right now. Skiing is fine and wakeboarding, while having a small wake, is acceptable too.

The trim tab is on the dash next to bilge and other switches. I find it isn't very convenient and wish it was attached to my throttle like a prop boat but haven't had time to dig too much into if switching it would be a possibility. I would think I should be able to do that. Add it to the list of a gazillion other things I want for the boat first.
What speeds are you making? I have figured out that my speedometer is off and when it says I'm hitting 50 my hummingbird actually shows around 41. And it GUZZLES gas. I've never had another boat so not sure if that is normal for all boats or worse with the jet
GUZZLES gas, hehehehe. Yea. I don't have an hour meter but knowing the hours I put on the boat and the fill up it takes. YEP! I'm getting ready to change the vacuum 4 barrel spring to hold the secondaries closed longer trying to get heavier throttle on just the primary body. It's a classic small block Ford (Ford guys don't crucify me for the term 'small block') with a heavy load and a 4bbl carb. I have the factory paperwork/tag and the motor is listed at 5.8l H something, looks like HC but that doesn't make sense. HO would make sense and I was told when I bought it it's 285hp which falls in line with a 351 HO BUT.... mine does not have GT40 heads which is typically what makes the extra HP and the HO classifications. <shrug>
Speeds, I don't know, I relocated my pitot tube when changing the trim tabs, it didn't work well before and the speedo works worse now. Haven't put GPS to it for a while but guessing low 40s would be doable with decent lake conditions. Factory tach I don't know how accurate it is but I can push wide open and bump 5500 RPM and settle down around 5200 on the tach. I usually shoot for 4500 on the tach for water sports depending upon who's behind me.
I had carb rebuilt by a good carb guy. Mine's still just a little odd starting once warmed up. Cold, pump the throttle twice and set it in fast idle and it'll start immediately. Warmed up and shut off for a few minutes.... it's just gotta be cranked a while. I think it's running a little rich, carb guy told me to blah blah blah and I'm like, I'm an IT guy so I gotta look up WTH he means. You notice the dark scum line at the exhaust ports in the photo, it's a little rich smelling while water sporting behind it too.
Dude.... thats awesome!
But then again 500 hp would be FUN!I love the arguments you get when you say Four Winns and jet.... compound that with "Ford" and the marine guys just look at you like you have 3 eyes and are one of those people. I argued, albeit briefly, with a guy on the phone I wanted a starter for a Ford 5.8l, he says "Ford didn't make a marine motor..." yea, well, no shit, but they did make the long block for 900 some mariners to use so can I get a (insert any effn boat/mariner brand you want that uses a 5.8l Ford motor) starter please. Hey look, it's a starter for a F 5.8l marine rated, gosh be Wally, thanks! I've been thru it for plugs, plug wires & coil. I have it documented, SOMEWHERE what the proper parts are that can be safely pruchased from [insert local parts store]. Firing order is 351W order but the location of #1 in my Mallory ignition isn't where it's listed for a 351W. Not hard to figure out but it was still time I'll never get back.
I'm sure you've done some digging on the Redline Marine motors. Long story short, give a few guys a warehouse and they'll build ya some solid boat motors. I'd love to know more about the internals, specifically what cam and pistons were used. I've got this terrible hankering to pull the 351 out this winter and tinker a little. The AT jet says safe up to 500hp. I don't want 500hp outta it but then again.....
