I love your passion for history Merlin. Our ancestors did so much that we benefit from today and we should remember their hard work and sacrifice, they did it for us.

Nice job! For those that don’t know, 75 is fast on the water, let alone 100. We had an old Hydroswift (Utah company, now out of business) that did 50 after some tweaking. Not many boats kept up with it. Long story short Merlin’s boat is fast!

Good run, glad the transmission shifted properly. Hard to pull the heat away with warm water. The mail truck looks excellent, it turned out really nice. Should be a nice addition to the museum.

Really enjoy the giving back. The local museum should be thankful. Mailer looks great.

This is the most amazing thing I have seen in a long time. I never knew this was possible, now I want one to run around the lakes here in the Ozarks. Well done.

Hey Merlin.. Thanks for taking us along on Test Drive #2!! Always a great time seeing the passion you have with these projects... you are truely a master of your "art"... Very kind of you to donate the mail buggy to the local museum..love that you take such pride in the history of your town and do your part to perpetuate the historic pieces. Safe travels, friend❤️ Stay FROSTY... Keep your powder dry and your head on a swivel... 🇺🇸🇺🇸WWG1WGA🇺🇸🇺🇸NCSWIC🇺🇸🇺🇸

Great job on getting the transmission fixed, watched the last video, cool way to test the transmission before installing. Great video Merlin, keep up the great work.

Glad to see the Cummins boat back in the water. Sweet flames out the exhaust. Can't wait until new propeller is installed. Keep up the great videos.

Merlin I'm Frickin impressed by your work 💪 love that Cummings and the Boat Have a Great Day 👍God Bless America

Freaking Merlin out there living my dream as I look at my boat in my garage in tucson in the middle of winter I’m over it

Merlin that is an awesome makeover on the postal three wheeler . You do such a wonderful job on all that you do. I love seeing all your work you do or have done

Beautiful boat and family. Thanks for sharing.

I love the boat and jet sky videos

Love your boat there's nothing like triple digits in a boat.So cool a speed boat with 12 valve Cummins I'm sure it surprises a lot of people I have had many boats over the years I just sold my Hydrostream Viking with 280 Merc outboard it would run 107 mph scary fast.I owned it for 26 years. Your youtube channel is the best keep the videos coming.

I can't picture somebody skiing in the black smoke screen, but anybody that would ski behind Merlin is certifiable anyways . . . ..

Thanks for sharing. I worked with caterpillar one time to turn up a 3512A to get 2250 hp after about 15 minutes it was shooting a 6 foot flame out of the exhaust stack. We named it puff the magic dragon. That was the mid 90’s things have changed a lot sense then. I love all diesel engines each has a special place in my life.

I absolutely love the flame followed by the coal freight training off of it! Must look absolutely amazing at sunset from a distance. Another bucket list item added too the list ☺️.

I love that you restored that mail truck and going to donate it ,that's too cool.

I go to havavsu every year for vacation I would be absolutely honored to come check this thing out

Looks like your co captain and camera lady was having a good time she was the best looking thing on the lake. Fun videos. Thanks for sharing.👊👍😎

I staggered over that bridge in the early 60's a few times, probably barfed over the side a few times as well. Good old London🙂

I really like the way you do it for the passion in your heart

Sweet to see the boat working as you had hoped it would.

I have been saying for 40-some years that if a person was to put an automatic transmission in a fast boat with more pitch in the prop than the engine could handle at low rpm. The transmission would shift to a lower gear and when the boat comes out of the hole and reduces drag it would shift. I always wanted to try it on a 3-point hydro or tunnel hull. But everyone said it wouldn't work and they all laughed and said I was nuts to even try it. I'm so glad to see someone actually try it and prove that the theory works.!!!

Awesome job on the Cushman. Happy to the trans works well this time. Thanks for sharing.

KICK ASS BOAT...old school, hot rod, Cummins 12 valve Merlin style. I think that pretty much sums it up. Cool video with lake, bridge and sunset shots.

Love his Video's he Build's such awsome Vehicles and what him and the Kid did to his Truck.

I would think the lake authorities wouldn’t like all that smoke. Pretty boat.

At first I was thinking, watta waste, but after seeing the flame show, I was sold, lol

The Boat is coming along nicely ! Loving the Postal Van ! Thanks foe Sharing !

I read years ago that this London Bridge's original stones are just a veneer. To save on shipping, the faces of the stones were sawed off and that's all that was sent over; just the facade. So very little of the actual London Bridge remains!

Very nice Merlin...

I was 15 the first time I drove across that Bridge, back in '74. Been on it many times sense. I do enjoy the lake. Glad you have got that Bad Ass Fire Spitting Monster of a boat running good. Can't wait til you put the new prop on. Thanks for sharing your adventures with us.

Mail buggy looking awesome.

My dad drove one of the Cushman 3 wheel Post Office Trucks in his early days on an old route, and I remember some of the stories of the issues they had with those things.

Glad the boat shifted thank you for taking us out on the lake I miss living there

I had a similar problem on my pulling truck so we switched to reinforced high pressure lines for the trans lines and it fixed the issue. Expensive for hose but well worth it boats looking and sounding awesome❤❤

the whole project is badass!!!,luv ur work.runs in the family!!one of my favorite channels along with fabrats and others! more!

Looking forward to seeing you and Paul coming around on the lake when he gets that boat fixed up that he got from lake Powell.

CONGRATS ON MAIL TRUCK LOOKS GREAT!... YOUR BOAT IS A FIRE BREATHING MONSTER!! HOLY CRAP!

Hi from across the pond. I was told the chap that bought the old London bridge though he was buying Tower Bridge (the one that opens up) Great boat I'm jealous!

we put a heater core inside a deep trans pan and run coolant or water through the pan. we learned this on mud racing trucks that disappear in mud and not burn up now.

Hey this is the first time I`ve ever subscribed to a channel...Saw you on the wrecker games and absolutely fell in love with your rig.....old school power wagon with a Cummins...It does not get any better...Plus you don`t drive like a wimp...

Driven over that old bridge many times in London and couple of times in Havasu. What a backdrop to a powerful boat!

I’m pretty sure I seen this boat cruising thru the channel last year definitely a head turner. Love the boat! found this channel this past winter and realize that’s the boat I had seen lol great channel keep up the content!

Thanx for the tour & history, definitely interesting. Not to mention all the tech you've put into that boat. Pride in craftsmanship in all that you do, Kudo's!

A hot dog and a nap had me laughing my ass off. A man of simple things. Nice boat btw.

Family time on the lake, Livin the Dream Buddy, you deserve it!

Mighty nice rig you got there Merlin

That boat is incredible, Merlin. Good thing you lady doesn't mind going fast on the water, mine gets a bit nervous when it's a bit choppy at speed.

Man after my own heart...vintage jet boats and Der Weinershnizel! Just wish i was in AZ and not IL!

Beautifully done love the flame shots out of the exhaust beautiful boat. I love the sunset. Great job.

116 DEGREES ON THIS DAY. MYYYYYYYYY GOD. You can keep that my friend lol 😆

Merlin’s a great guy and team player, very humble for his immense knowledge

its rolling coll love it

Im 64 but when I was grade school age we went there and rented a paddle boat and you could see where they numbered all the bricks to reassemble it here. Not much of a town there at the time.

All the fishermen must love you.

She is running great congratulations

Our family and friends family came to see the bridge the first year it had water under it . We told the guy at some gas station we were on the way to see the London Bridge. He showed us a road map with a picture of the bridge, and he told us to not waste our time going out there. I do remember it was HAWT !!!

I grew up on a fresh water lake in the panhandle of Florida. My father said there were only two speeds for the boat. Full throttle or full stop. Looking back on that time I can’t believe my dad put up with all of boat motors I killed. He never scolded me about, and I guess he knew I was safer racing around on the lake than on the road. Great time to grow up. Remember it’s the first 40 years of childhood that are the hardest.

Great job on the Cushman mail cart or maybe trike

Good to see you guys out at Chico's today, and always fun chatting with you. Great to see the boat rolling through the channel as well.

This is awesome to see the Cummins boat up, and doing its thing! Nice beautiful shots of the London Bridge, and all the other beautiful landscapes! Get'r did! :)

for the new prop test run, I'll get binoculars and watch from the bank. 100 mph-ish on the water, for some reason scares me a bit. No issue with cars or aircraft. Love the Mail Truck ! A running and driving museum piece.

Love that boat. Shes definitely alittle on the HOT side...LOL..Great Video...

German 101: Der Wiener, Das Schnitzel when combined = Das Wienerschitzel!

Nice job that speedboat is a beast Merlin, haha hard at play need food & a nap I totally appreciate that & I'm only 55, great video thank's for sharing 😉👍

The boat was cool. Cant wait to see new prop run

Damn, Merlon! I've not had a Der Weinerschitzel hotdog since I lived in Hobbs back in the 70s!!

I really like what you do. I’ve been a Cummins lover since my first 98 12 valve. I love your boat. Such a cool idea and build.

👍👍 right on Mr.Merlin..the boat's kick ass...thank you for another video 👊

Nice boat, but wouldn’t want to ski behind it! LOL

Very KOOL Boat Merlin

Glad to see you worked things out.

Back in the mid 70's I ran Ski-Mod. and Unblown Gas. The hull was a Mandello Flat Bottom. We held records twice. When I changed to a Minkins Props, not sure of the spelling. The boat came to life. I'm sure the tech guys are long gone but their tech group told me what the boat was doing in the water before I did. May be worth a try. Ps. I;m 74 now.

That's one bad ass Cummins powered boat you have there sir

Amazing video you guys !!!!

And that's how you do it, good job brother

Merlon. That engine absolutely rocks. Your lady getting the shots of the flames coming out was outstanding!!!👍🏻👍🏻👍🏻🇬🇧

I person hates to see that much smoke pollution on a lake but i like the great work done my Merlin on the boat.

Need to start doing Saturday evening ski shows again under the bridge

Great boat! Mail truck looks awesome!

Love the boat BTW it is awesome. Just need to reduce the coal!!

Nice job, that is sweet boat!

perfect Boat Engine

You hooligan! Blipping the throttle under the bridge is not the sort of thing us grown ups are supposed to do! 😉 I grew up in Essex in the UK, sometimes a bunch of us would head south through the Dartford Tunnel (often on the way to Brands Hatch) on our motorcycles, and pretty much every single biker tested the echo from the tunnel walls by using way to low a gear in order to max the engine rpm. To be fair, were were a bit younger than you.

That is one awesome boat Merlin!!!😁😁👍👍💪

Bad ass man them flames in the sunset are just some wicked shots and the bad ass sound of the 12 valve sheesh the boat looks Hella fun to steer cummins 💯🇺🇲👌🏻

Glad to see you have the boat sorted. Can't even imagine 100mph on water. I went for a ride in a friends boat at 55 mph. It seemed MUCH faster. Stay cool.

I just caught this video and thanks for sharing!

Good and fast👍

Absolutely impressive! Cummins the world boys!

wow the postal truck looks better then new & congrats the boats great !

You did a really nice job on this boat but seriously, who wants huge black clouds from a boat?! I certainly wouldn't want to ski behind that boat or honestly be on the same lake with that exhaust.

The Cummins reminds me of all the equipment that Felonious Gru runs.

Looks like you guys are having way too much fun. A better type/quality coolant hose and good to go. Thanks for sharing.

Being in Havasu and having boats, did you know my friend Russ Nyland? He used to tow boats all over that lake! Love the channel man! R.I.P. Russ and Ashleigh Nyland

You gave me a flash back to 1993. No hole is too deep or sloppy when you are driving with a big Johnson!

Had no idea the water was so warm! Looks like you had alot of Fun!

Sound ❤
