Review and Test Numbers for New Pro-Drives

Postby pwhnts5 » Thu Sep 19, 2013 10:37 am

I know there has been a lot of fuss'n about the new generation PD speed and a lot of discussion about different props needed, but here are some real numbers for our rigs with the new motors and the EFI set-ups and EFI with our head, intake and exhaust.

Testing conditions:

Location: Mississippi River just below Lock and Dam #13 at Clinton Iowa - Main Channel for deep water with wind and current, both directions average speed. Out of wind and current - East side of river - North end of Cattail Slough at Fulton, shallow dead end bay of Cattail with 1-2 feet of water going to no water in mud far north.

Every test run is on the exact same GPS track for each location.

#1 Boat 1860 Phowler Extreme with stock Gen 3 Prodrive carb model.
Standard Equipment, including tank, battery, lines, gun box etc.
Average Man Weight was 220 lbs each

One man -26 MPH deep water
Two Men - 25.5 MPH deep water
Three Men - 24.6 MPH deep water
Four Men - 24.1 MPH deep water
Five Men - 22.6 MPH Deep Water

In deep water we had no prop slip and the boat planed out in less then a boat length with up to four men, maybe 3 boat lengths with the five man load.
We gained 2-3 mph out of wind and current in 1-2' of water.
In the mud the motor just digs like a tractor, 1/4 throttle with the 3 blade trimmed down and boat is going, start moving and crack to 1/2 throttle and it is up on step.

Average RPM Range: 4250-4350 best speeds regardless of load.

Boat # 2 - 1860 Phowler Extreme withCX36 Gen 3 PD Stock EFI
Standard Equipment, including tank, battery, lines, gun box etc.
Average Man Weight was 220 lbs each

One man -28.5 MPH deep water
Two Men - 27.8 MPH deep water
Three Men - 27 MPH deep water
Four Men - 26.4 MPH deep water
Five Men - 25.2 MPH Deep Water

In deep water we had no prop slip and the boat planed out at once with up to four men, maybe 2 boat lengths with the five man load.
We gained 3-4 mph out of wind and current in 1-2' of water. Hit 30.5 with one man in a foot of water.
In the mud the motor just digs like a tractor, with the EFI it will idle in the deep mud and junk, 1/4 throttle (3200 RPM or so) with the 3 blade trimmed down and boat is going, start moving and crack to 1/2 throttle and it is up on step and right up to 4400 RPM.

Boat # 3 - 2060 Phowler Extreme with a full hard blind (220 lbs) fully grassed with CX36 Gen 3 PD EFI with Illowa Heads and Exhaust
Standard Equipment, including tank, battery, lines, gun box etc. Additional Equipment - 4 dozen duck decoys, 1 dozen goose decoys, stove, heaters, 20# propane tank, robos, poles, and all hunting gear for each guy.

Average Man Weight was 230 lbs each (one guy is over 275).

One man -27.5 MPH deep water (before the blind was added this boat hit 29.7 with just one man out of wind and current).
Two Men - 26.9 MPH deep water
Three Men - 25.5 MPH deep water
Four Men - 24.5 MPH deep water

This is a big blind set-up that catches a lot of air, we estimate it was carrying around 1500-1650 lbs with the blind, people, decoys and equipment.
In deep water we had no prop slip and the boat planed out at once with three men, blind and gear in about three boat lengths, with four it took about 20 yards.
We gained 3-4 mph out of wind and current in 1-2' of water.

In the mud the motor just digs still digs like a tractor, even with the big blind and gear, with the EFI it will idle in the deep mud and junk, 1/4 throttle (3200 RPM or so) with the 3 blade trimmed down and boat is going, start moving and crack to 1/2 throttle and it is up on step and right up to 4400 RPM. With the head, intake and exhaust this big rig jump right out of the hole in shallow water and mud/weeds.


Boat #4 - 1860 Phowler with Phowler TCBS Light Marsh Blind HARD BLIND (170 LBS)with all the extras WITH UPGRADED 2012 PD X36.
THIS IS A 2012 PRODRIVE X36 WITH GEN 2 GEAR BOX WITH NEW EFI, 4700 COILS AND ILLOWA HEADS AND EXHAUST AND OLD STYLE 3 BLADE PROP.
Standard Equipment, including tank, battery, lines, gun box etc.
Average Man Weight was 220 lbs each

This rig before the addition of the EFI and Illowa Performance Kit would run 22 mph with two men and gear, 17-18 mph with three men and had trouble planning with four men.

Results after adding EFI, Illowa Kit and 3 blade prop.

One man -28 MPH deep water
Two Men - 27.2 MPH deep water
Three Men - 26.5 MPH deep water
Four Men - 25.7 MPH deep water

In deep water we had no prop slip and the boat planed out in 1-2 boat lengths with up to four men.

We gained 2 mph out of wind and current in 1-2' of water. Hit 30 with one man in a foot of water.
In the mud the motor stayed hooked up, not a well as with the GEN 3 box and blade, we had to keep under rev limit trimmed down at 1/4 -1/2 throttle until the prop stayed hooked up good, then slowly trim up to jump on step. Just like the new motors with the EFI it will idle in the deep mud and junk, 1/4 throttle (3600 RPM or so) with the smaller 3 blade trimmed down and boat is going, start moving and crack to 1/2 throttle and it is up on step and right up to 4600 RPM.

This rig with the smaller three blade runs right at 4400-4500 top speed, regardless of load.



I have heard of guys not having enough prop for these new set-ups and the Gen 3 gear box (i.e. no getting the top end speeds or having to stay trimmed down to keep RPMs under 4600), but that is not the case with our larger rigs up here. I could see this being an issue with a smaller boat with a much lighter load, but we are seeing pretty impressive improvements with all the different combinations we have tested so far. Speed is great, but not at the expense of performance with big loads for our customers with these large boats with blinds and 3-4 men. These motors, and the old motors with new EFI kits) are moving these big loads as well, if not better then any previous performance motors we have run (and we have run them all, from all the different brands and all the different mod options, all the way to MB 7000 and the PD and GT motors with Stage 3 set-ups with cams, pistons, roller rockers and mikuni carbs). Yes we sell PD primarily, so I am a bit bias, but the numbers are the numbers, anyone who knows me and how we do business knows we don't bs on the numbers and loads.

Most folks know that PD is working on more prop options for these new set-ups and for the retro fits to older motors, we will be testing these also to see how they do, IMHO, with our bigger rigs with big loads we think the current prop is pretty spot one, so any improvements will be icing on the cake.
