(2) HDS 12"s w/ Smartcraft engine data.
(3) Battle Born 100 Ah lithium batteries for the 36V trolling motor.
(1) Centennial 1150 Group 31 battery for outboard cranking and accessories.

215 LB Driver - no passenger.
I pack a fair amount of tackle and gear. I would consider my boat loading as medium heavy. These were the first test runs I made since I replaced my (3) Trojan SCS 225 batteries for (3) Battle Born 100 Ah lithium batteries. By replacing my Trojan batteries at 66 lbs each = 198 lbs for the Battle Born lithium's at 29 lbs each = 87 lbs, I removed 111 lbs from the rear engine compartment. I noticed a big improvement on the holeshot and mid range acceleration. My top end speed only increased about 1 mph. I have not had a chance to give the new lithium batteries an all day fishing load to see how they perform. The little bit of trolling motor work that I have given them has impressed me.
Test run information - Sunday 12/10/2017.
Lake Whatcom - deep clear lake - elevation 312 feet above sea level.
Light chop - excellent running conditions.
Air temperature 45 degrees.
Surface water temperature 46 degrees.
Prop to pad measurements were based on the best top end speed and performance from each prop.
Speed readings from my HDS-12 / Point-1.
Engine data from my Smartcraft linked to my HDS-12.
25P Fury 3 blade - stock prop w/ no vent plugs, all holes open.
3 1/2" prop to pad.
5900+ RPM's.
75.6 MPH
Water pressure 20+ PSIG.
Holeshot was very good.
25P Fury 3 blade - minor work by Mark Croxton w/ no vent plugs, all holes open.
3 1/2" prop to pad.
5900+ RPM's.
76.2 MPH
Water pressure 20+ PSIG.
Holeshot was very good.
26 Tenpest Plus 3 blade - repitched to 25P B&B by Mark Croxton w/ 3 large vent plugs.
3" prop to pad.
5900+ RPM's.
76.2 MPH.
Water pressure 20+ PSIG.
Holeshot was good - minor ventilation at break over. Had to feather the throttle.
The reworked 26P to 25P Tempest Plus had a little more bow lift but the reworked 25P Fury had a better overall feel and a quicker holeshot. With a passenger and a little more gear load, the Tempest Plus might be the better performer. After removing the 111 lbs of battery weight from the rear engine compartment and seeing the performance gains, my tournament partner and I need to throttle back on the "wobbly pops" and lose some weight. I hope this information helps some of you or at least gives you a starting point. For the record, I couldn't ask for a better built boat. The design, layout, quality and attention to detail are first class. All five of my Triton's (21Tr, 21X, 20X3, 2014 21TRX, 2017 21TRX) have been great and I have only had a few minor issues that were handled quickly by my dealer (Nixon's Marine). I just don't get the Triton bashing. I can afford to purchase any brand out there, I still choose Triton. Merry Christmas and Happy New Year to all.
