Mercury Marine has no desire to see their older motors keep on going forever. They stop supplying parts soon after the warranty expires, in hopes that you'll just go out and buy a new one. Yamaha does the same thing (aquiring pre-1990 parts for a Yamaha is a crap shoot).

They are letting the boat set deeper so that the motor sits higher on the transom. It's a give/take scenario. But at the end of the day you still have a skeg, the full diameter of a prop, and a cavitation plate IN THE WATER. You can get the same effect a tunnel has by trimming up a flat bottom boat and causing the bow to raise and the stern to dig in a bit. The full bottom allows MORE trim angle.

No it won't. And I have a perfect place where we can stack up a wall of concrete blocks and prove it ? When ya wanna do it ? 😊💲💰💸 Pay up your insurance premium and let's go have some fun. 😁

Maybe you missed it......But this whole conversation got started because someone was considering buying a tunnel hull rig for the White river chain. I only poo-pooed it because to me that's a stupid idea. 😂

I 100% agree. Women were "designed" to give birth. And if they wanna blame MEN for the pain during child birth they need to be told that if WE had built them ....then they wouldn't have ANYTHING to piss & moan about. Odds are that we weren't trying to knock them up to begin with.....We were just poking fun, and they got all serious about it. Men's nuts were NOT designed to be hammered upon. As a matter of fact they were placed so that nothing could get to them naturally.... unless the guy did something stupid.

😂 Yeah you can hear it chewing sand! Try that over gravel and rocks, I dare ya. Guys on the Mississippi did that alot too.....until somebody invented these.....

They probably don't believe there is any water in it, and they may be right.....But it needs to be verified for sure before going any further. No need to be cranky about it. 😅. Pretty simple task, I suppose they'd rather be doing something more difficult? 😂 Since they are already pissed off, go ahead and have them do a siphon test on the fuel supply line. If all the above is 100% good.....then slap a new diaphragm and gaskets in the fuel lift pump and go test it.

Regardless of what hull you're pushing....This is the absolute minimum amount of water you need for a prop outboard to safely clear an object at WOT.... 2 cylinder motor 6 cylinder motor....

What are your plans for it? Just curious.

Very few "Certified Mercury" places will check the oil reservoir (because they don't teach that at the certification centers) and I'm not 100% sure how or why water gets in there..... but it often does. Condensation from the pressure hose possibly. I have a giant glass pickle jar that I can dump the reservoir into and let it set for 30 minutes to see if water separates and shows up in the bottom. You can't see it by looking through the milky colored plastic reservoir tank. You don't have to waste the oil if there is indeed water in there, just let it set overnight, clean the hoses, the pickup tube & screen, and the engine mounted reservoir, then siphon the UNCONTAMINATED oil from the top of the jar. You'll only end up wasting a pint or less of oil......'cause that $#!t is expensive! 😅 Then repurge the O/I system....and you're good to go again.

Your welcome, but it's only "help" if you follow through. So how long before you know the condition of the fuel and oil? Water just sitting within those components will cause permanent damage. So let's get busy! 😊

Speaking of insane catches of hybrids..... wait until you see what the guys at Truman and elsewhere are doing once they get proficient with their Livescope units.

Water in the fuel, and/or water in the oil reservoir (very common) will cause that without setting any trouble codes. So eliminate that first. A clogged or leaking fuel supply hose, bad primer bulb, or a bad Fuel pickup pump diaphragm can also cause that symptom without setting any fault codes.

Try that with gravel instead of sand or silt. I dare ya. 😅

Nice! 👍

Now Now..... Let's at least set the exaggeration factor at a setting that makes it somewhat possible. The skeg is 6 1/4" , the prop is 10.5" diameter on a 140hp, and the water intake is 14 " from the bottom of the skeg. I'll buy that you chewed sandy silt for 25-35' but you didn't "clear" 6" clean. Had there been a rock in your path you would have been on a boat camping trip until the tide came in. No matter how flat the hull is at plane.... you still need water from the cavitation plate to the end of the skeg, or you'll blow out. And on a 140 that's about 22"

I was under the impression that Pomme was fast becoming the walleye capital of Mo.

I get paid Outboard tech rates....But I'll gladly twist rope instead of twist wrenches. 😊

I'll bet ya $100 that those motors will still be out there pushing boats around long after everyone has forgotten what a Verado or a ProXS even was.

Listen...... Sending me to bed before I'm ready to just lay down and SLEEP ..... is just asking to start a fight. So whose side are you prepared to take ?

Really? Swapping out a jet foot..... ain't about nuttin' 😅 But to each their own. 👍

That's a sexy looking drifter, but I'd forgo a tunnel Hull design. By raising a section of the hull you are just forcing the lower portion of the hull deeper. You can prove that to yourself by making "hulls" out of 15" pieces of aluminum foil, putting a handful of penny's in them and floating them in your kitchen sink. Regardless of the position of the outboard in relation to the hull.....you're still running the motor at the same depth (from cav-plate to skeg) ya know? It's a bit confusing, but think it through. In other words....Show me a shoal that you can run in a tunnel Hull....that CAN'T be run in a flat bottom Jon.

Oh yeah 🙂 I think it's good for them. Orion gets the dark meat strips trimmed from White bass too. I learned to cut him off after about 10 of them though. If he has too many his farts will run everybody out of the house. 😂

Reminds me of the Roostertail brigade around here. They are afraid of getting a hook in their hand, so they drag them up on the bank, put a foot on them, reach down with pliers to rip the hooks out, then kick them back in the water. 😠

Now why didn't you go over there and help him lash those down on the cargo rack?
