the prop witch doctor from pt's name is Marcus i think, they call him funky monkey

Thanks for the link LaAngler. Very much appreciated.

if you set that thing up right it will run in just a few inchs of water and will take off in just a few inches. I have had my boat in about 3-5 inches of water and run without a problem and it will get up on step in just a few inchs more then it floats in

Silted in?? Just get a Gator tail !!!!

Dink- Motor just came in. Boats been ordered. I'm building the trailer now.

Emailed PTProp about a tunnel hull specific prop. I'm thinking my jack plate will be a must. The Bobs Stabilizer plate shouldn't hurt a thing since pontoons and trim tabs are a no-go. Weight distribution is sounding important. Oh, one other ting I was considering... the new 'Blade Saver' by Black Fin Skeg.

Blackfin makes a quality product

I was thinking the same thing! but I figured he already had the motor!

Dat is a good prop for a tunnel,I like the 3 blade design better. The 4 blade is heavy and if you do alot of forward and reverse you will wear out the clutch dog in the lower unit.

Here is my setup, 18x42 with a merc 40 and 14 pitch prop. Notice the cup in the blade,probably could show pic to a prop guy in Ar and they could duplicate it with no problem. Aluminum floor has Hydro turf covering and gaz tank sits front left. Soft mud it stands up in less than an inch, if it is harder it just depends. Dry, runs 38 gps with no mods. Hope these pics help you.

What are you going to be running though? Lakes with rocky bottoms? Rivers with Rocky Bottoms?


I wouldn't worry about a skeg if your running mud bottoms, yes you will hit a log or 2 eventually, but who doesn't?

got dat same motor der Raymond...

Will yours stand up if it is soft??:*****:

:smokin:

Tunnels have virtually no reverse power since the motor sits so high out of the water. They go forward but struggle backing up.

Thanks for all the input everyone. My boat should be available to me next Friday. Once I have it I can finish my trailer and get my boat setup figured out. I was beginning to worry about the deep tunnel and prop combo. Now I know it will be a nice rig once fine tuned.
If anyone has more to add please do. I appreciate all ideas.
Thanks

I just went thru this with a new 1652, non tunnel, with a 40 four stroke Yamaha EFI on a 6" jack plate...

Call Powertech Propellors and tell them what you have and what you want out of it and they will hook you up, super good guys to deal with... I ended up with a four blade 11 pitch wheel that gave me the hole shot I was looking for... These mid range four strokes are a different animal from the their two stoke cousins, I would like to try the equivalent prop in a three blade because top end does suffer...

Good luck,
Hydro

Hydro, what are you running with the 4 stroke?

28 mph fully loaded, but it will get on step within a boat length...

Boat is a camo 1652 G3 DK, skinned out with rod box, floor, sides, ect... Empty boat weighs 640lbs... Throw in motor, batteries, 8 gallons of gas, foot controlled trolling motor, jack plate, Yeti cooler (had to throw that in for the guy who was ragging on Yeti owners), fishing gear, seats, a rod box full of BS, my big arse and the dog and its probably pushing 1300-1400 lbs easy...

This is my first four stroke and I really am liking it, just an adjustment from anything else I have ever run...

Powertech said I could get into the low thrities with a different prop, but thats not what I was looking for... My break in period will be up in another month or so and I am really looking fwd to seeing if its turning up the 6k rpm its supposed to, by the sound of it I dont think it is but again these are different animals...

Lots of torque down low, really quiet, smooth, and sips fuel but definately not a "screamer" on the top end like the two strokes are...

Hydro

anyone have any dealins with the 40hp 4stroke suzuki

Used to call my buddies 40hp 2-stroke a GoZuki... was an excellent motor.
