Default Boat pans

If you can run a full length pan.

I'm not a boat person but riding around in a friends 496 boat on the lake
it has a wet sump, it struck me as were bouncing around sideways to up and down, the pan and block must have some pretty good oil control.

Wonder what the oil control features are in a milodon boat pan, one I looked at was no deeper then a car pan.

Probably a full length windage tray.

I'd bet it's a great baffle / windage tray setup with trap doors and chutes and ladders.

Do the Vortec 7400 and 8100 and 572 have factory windage trays like the Vortec small blocks do?

Slightly off topic but I use a marine valve cover on my BB. Was the only thing I could find short of an $$ fabricated cover to give some space between the valve cover and my brake booster.
The lighting isn't so great in this pic but you get the idea.

Im sure when my friend took it out on the swells in the gulf it was doing a little more bouncing around

He let me run the boat, it will run 70, 25 foot weighs around 6,000
lives next door to me, when we backed it into his driveway had it
parked I said you know I've never driven a boat before.

70 on a lake was easy, don't think I would have had the nerve to run it very fast out in the ocean with my vast boat knowledge.

Most boat designs allow for a full length deep oil pan and that allows for an oil pickup in the center of the pan which has been proven thru 3d cad designs to be the best placement. a lot of boat pans also hold from 10 to 14 qts of oil.
As always, if there are oil starvation problems, install an accumulator.

BTW, try sitting on the transom next ride. The movement there doesn't feel nearly as bad as up front.

Back when I was 18 I went for a ride in a friend's speed boat in a cove in Colombia South America. This little speed boat was a Corvette look-a-like with bulging front fenders, two small seats, and a HUGE big block. It was right behind us. The cove was very calm, so we were able to almost reach top speed for the craft. The gauge read 90 knots on one run.

Let me just say that my back was so sore from the skipping that I couldn't walk properly for almost 3 days.

LOng story, short form, after fighting for nearly a year to get this 350 powered mercruiser IO 22' Chaparral on the river, my friend managed to cruise it at 55 mph....up and running, ran fine, super happy, next time they went out last winter, they skipped a large boat wake....dumb asses......they went airborne and blew the engine 50 ways from sunday.....

another engine in the boat now....last rodeo for me on THAT boat....no more......5X over the transom on account of totally not reading the books first.....not my job, I just hired help with the room and the hook.....

they were walking funny for a while too, even though the stood up when they left the water, knowing they would die if not....

even I knew enough about large boat wakes....

I would thing the engine would have a rev limiter on a boat for sure
was that not the case ? My friend got rid of the boat but if I remember
right the 496 ran to about 5200 rpm I assume much over that a rev limiter kicked in.

I was not with him but when he took it to the gulf in the swells you
know the prop had to be coming out of the water.
