what pitch prop are you running

Sir what Prop your riding on ?

Your video was a huge help. Thanks

When u use a straight edge to see where it ends up on cavitation plate is the motor fully trimmed up or down? This a great video I have the same type hull.

Since you asked for feedback...I will oblige. Get an Atlas jack plate 4 " setback installed on that transom if you are SERIOUS about fuel economy and better performance. You can thank me later.

I agree. One more hole should be perfect.

Big undertaking brother. Hell yea.

Chine walk at 43mph lol. Mine doesn't start to about 68 then really bad around 75.

Would you reseal the mounting bolts every time you move the motor up/down to test it or would you just seal them when you are completely done testing and find the correct height?

Love the clamped breaker bar...bloody awesome 😄

Great video...did you ho ip an extra hole in the finish?

Could you point to your fish finder and show where your talking about seeing the lure and depths and fish

Nice video and editing work!

Efficient..thanks

Good explaining i follow u

So was that 3 or 4 holes up from the lowest the final position?

1 inch up for every 1 ft back in hight over the bottom cavation plate the lowest plate

Doing the same thing with my Astro Bass Boat.

Aluminum is a soft metal.

Please use flat washers!

I would go up 1/2 a hole, lol. Nice Video ,thx.

Hi, I have a 2018 190 TX with a Mercury 115hp EFI 2,1L. I am running with a 13" x 19 Pitch prop. In the beginning with WOT I can reach 5500 rpm 42 mph. loaded with fishing gear and ice boxes. I don't know what happens, now after 1/2 hour on the water, the speed drop from 4mph, to 30 mph then 20 mph. I service the engine every year. Change engine, gear oil and water pump impeller. Also scanned the engine but everything is OK. Seems that speed drop when the engine is hot. Please can anyone help? Also what correct size prop should I use?

Great video thank you. I also have a stepped hull and have been chasing an issue with getting on plane and not reaching full RPM. I think this may be the answer. Can you tell me what size & pitch prop you are using?

I really have liked all your videos. This was a great follow up to part 1. The only thing I see is my dad always yelled at me if I used an extension on my torque wrench. Maybe do a video if they effect the torque limit or not when used. Then I can rub it in his old face if you prove it's a myth, lol.

Nicely done ✅

O

that's why they have hydraulic jack plates

thank you !!!!!!

Have the straight edge line up from bottom of V exactly with the engine water pickups

1:26 shows the outboard sits further out from the transom than the typical design allowing such a high lift.

Where did you buy your reinforce plate

Wow, your FF is absolutely dialed

I have a Grady white 23 ft 300 hp and have it on 3rd hole and think I may move up to 4th hole

BIG Calico #7

Good job

Helpful video for any boat and i know with experience it can be tough dealing with outboard transom placement on any boat with a step hulls

I think you could go higher it is still a hole to low.

Go up another hole and trim it less. Thanks for the video Larry

So what is your height from the cavitation plate to bottom of hull ?

🎯👍🏼

go up 2 more and get a better prop

BURRIED!!!! then ALMOST ok

Was that a 25” shaft on a 20” transom?

if is bottom hull of your boat,alluminum?

Interesting but it would have been a lot better if you had a chart with heights and changes at the end you could compare apples to apples with. I raced offshore for many years and it was pretty much trial and error. Higher the better within reason. We ran low water pickups and cranked them up until the blew out and then down a bolt hole. The difference was totally amazing in speed, RPM and handling. Higher the better.... I was manager and director of Rabco Marine for years. We did really well until the cats came on the scene. We'd still beat them if it got rough enough. By the way....lower unit drag kills speed at some point. 3 EFI's could be faster than 4 on certain hulls. 4 will get a 35 out of the hole so hard everyone would fall down...but 3 was 6 - 8 mph faster on the top. We tried them all...believe me

Great video

Will having the engine too high or low cause the boat to shake ?? Having this problem. Thanks

great job of explaining what you are doing and why you are doing it. very useful. thank you

When you have a stepped hull like the one you have... Your best option is a good Jack Plate then you can fine tune everything without any hassle... Good stuff thanks for posting... used to race Molinari tunnel Hull boats with Mercurys... we used to go up or down 1/8 of an inch at a time you can't believe the difference, props make a big difference also... once you change one thing, you're changing everything LOL
