Finally done. Big Min Kotta Ulterra went on this arvo, motor has been lowered, spray guard fitted for Furuno transducer. Fuel up, iced up, baited up and ready for first run to the reef at 4am. Played with the Ulterra in the shed. Now THAT is what I call a flash bit of anchoring gear. Should run about 250 k's tomorrow so can post some meaningful numbers with a full load of gear. I do have an RX 4 16" coming on an expectation that this prop will be a little to heavy to swing at 5500 RPM now that it is actually submerged.
Good luck with it.
Not sure if you got the message or not but you have more or less answered it .
Cheers

Good reef run yesterday and just had a talk to my dealer. 253 k's yesterday on 235 litres. about 4 litres of oil. heavy load of gear (and fish coming back). Calm conditions for run out, sloppy 15 knot sea for trip home made for heavier running and fuel use. Still significant prop slip below 4000 RPM and WOT of 5300 with trim.
Plan. Getting an RX 4 16 up to trial and dropping the motor 1 more notch. Was only lowered 1 notch last week because the bottom bolt mounting position made it a difficult option to take any lower, but will take this option next.
All up very happy and still with, I think, some room for improvement. The big win is the fuel burn staying consistent with RPM well into the rev band and incremental speed increase.
These are heavy load number.
4350 RPM 46.5 lPH 48 kph Econ as per gauges 1.1
4700 RPM 55 lph 55 kph 1.0
4800 RPM 60 lph 60 kph 1.0
5050 RPM 65lph 64 kph 1.0
From here on fuel burn curve rapidly overtakes speed with 92 lph @ 72 kph down to .7 kpl on the economy gauge.
If my new standard is going to be 1 litre per kilometre then I have just upped my cruising speed from 30 MPH to 40 MPH and that is an outstanding result when I am running big miles.
As a side note. How f$#@$ good are the Min Kotta Ulterras. A full day at the reef with "push button" anchoring.
Hi mate,Originally Posted by kc
Congrats on the new setup! It looks like this is a regular trip you do?
So just to get an overall view. Can you just list how many litres you would of used in the old set up and how many you used in this trip to get an idea?
Are you happy enough to recommend the G2?
Thank you
On yesterdays trip. A run to wide of Knuckle reef with a bit of running around I would have burnt 400 litres and maybe even had to throw a jerry can in as well. Estimate (based on at least 30 trips to the same area over 18 months with the 250 yammy) savings at about 170/180 litres, offset by about $70 worth of oil so about $150 better off for the run. Also being able to run a good 8 mph/12 kph faster gives me more fishing time when I run that far. Had I ran the yammy at 64 kph (pretty much WOT) I would have burnt about 450 litres.
Heading out tonight after work for a shot at some reds wide of Holbourne and a few macks on the way home at dawn and this will take the engine into close to 30 hour range so interesting to see if oil consumption starts to slow. At present oil burn seems to be about 50/1 and it should ease back to near 100/1 after the break in period.
Sorry, second part of the question. Would I recommend the etec gen 2. First off what I wouldn't do is bag the yammy. I was a lovely motor and just not suited to the boat. I have a yammy 60 on my creek boat and it runs on just about thin air. As to recommending the etec. I owned and had a perfect run from a Gen 1, and we all know how they ended...the new version of the black anchor. My experience so far with the Gen 2 is that it will be as good as I expected, but it is not there yet, which I think is a case of combined engine height and prop selection. It is not as good at cruise speed as I had hoped, and it is far better in the mid to high rev range than I had expected. The big surprise is what I seem to be achieving as my new "cruise speed". Ask me in 100 hours. So far, if nothing else was changed, this has been a great upgrade, but I do expect it to be even better. the prop slip at lower speed is still very significant.
Be interesting to see how you get on. When I initially started trialing props with my rig I had abysmal fuel use at low revs - just coming onto the plane and low speed planing. Ultimately the fix was a multitude of things in combination - a better prop (Rebel in my case) and addition of planing aids (trim tabs and a foil) to simply get the hull to work better at the boat speed that the revs corresponded with. Doing these things has seen economy at this rev range effectively double - not to mention the difference in ride. Have you tried the Rebel prop again with the engine lowered?
I'm interested to see and know more about the electric set up and how it goes. What's the battery life out on the water like? Do you covert 12v to 36v on board?

Hi Lovey,
System is set with 3 deep cycle 100 Amp batteries in series so a fair bit of weight to carry. Ran pretty much non stop for 5 hours with no loss of power and when I threw it on charge back in the shed I was still showing 3/4 full batteries. On the down side I went out last night and the remote failed =(. Thought it may have been a dud battery and didn't have a spare on board. Had to actually use an anchor!! & I left the retrieval bouy at home. Replaced battery this morning, still not working so took back to dealer. There is no manual override, no remote means no electric motor.
thanks a lot mate. Just wondering, with the Auto deploy function, can you lower the unit right out in the horizontal position before rotating it down into the water? For your set up its not an issue but many have boats with a bow rail that would interfere with the auto deploy if the shaft is right up when you deploy it.
Doest that make sense?

Having done some homework after getting home there is an auto stow override in the event the remote fails, but not an auto deploy. There does not appear to be the capacity to extend before tilting so anything needing to go "under bow rails" would not work. Had the hand remote replaced without hesitation this morning by dealer. Opened the box on a new unit and took out the remote rather than make we wait for a new one. Good service but a good customer/caring dealer issue rather than company policy by Min Kotta I would think. I have however, ordered a second unit. A $250 insurance policy to live in the glove box on the boat.
Interesting thread kc.... Now I must be living in the 60s... Can you explain does the Minn Kotta hold your position without the need to anchor? It must be connected to your gps or have a gyro or something. Sorry about the stupid question but I've never heard of such a cool bit of gear if I am reading it right.
Some of the higher spec electrics have a gps receiver and a heading sensor built in. They can hold you in position, steer you in a direction, steer you on a heading allowing for set and drift and even record a track and follow it backwards and forwards. They can also be hooked up to your on board gps to go to waypoints etc.

Badone. A picture (or this case video) is worth a thousand words. The best bit of deep water fishing kit since the invention of the sounder.
