Getting Close

Almost time to get that call and tell me “Your boat is here, come pick it up” so I’ve been gathering everything I need to rig it out. It’s not the most luxurious model Lund has to offer (Rebel 1750 SS) but has everything I need to be safe and enjoy a great day on the water for many years to come. You might have seen earlier posts asking stupid questions but after many hours of reading and comparing all equipment I ended up with the Motorguide Xi5 pinpoint/sonar 24 volt, a HDS 9 Gen 3 Lorance Total scan for the counsel and a HDS 7 Gen 3 for the front. I have all the wire and connectors to network them all together and have complete control of the trolling motor from my seat. I guess I have a couple days of rigging once I get it home before it hits the water. (Running this by you for any add or comment) I plan on running a electrical power strip under the dash for all the electronic power for the equipment at the counsel and the power for the backbone, then taking a main to a switch on the dash so at the end of the day I can shut it all down. That power will come from my cranking battery but the connections will be isolated to a power source under the dash. The HDS and Trolling Motor in the front gets power from the front as usual but the trolling motor will come off the 24 volt side of the front batteries and HDN off the 12 volt side of the front.
The only thing that’s still hanging out there would be an extra prop.It comes with a Spitfire 4 blade but I like having another on hand. With that being said, until I run it I won’t know where it’s operating at so that’s some thought for down the road.Any thoughts or ideas to improve on this,? I’d like to hear them.

you may get interference on front locator due to trolling motor also my dealer said you should not hook anything to the 24 batteries except trolling motor . running locator of one of the set will run that battery down faster and the other battery will compensate and you will wear them out much quicker.

Thx mwal, I think the front 12 volt power supply comes from the cranking battery in rear and the trolling motor 24 volt does com from the 2 batteries up front.At least that’s what the wiring schematics show.

What’s the HP

The HP on the SS (Counsel model) max 90 hp. and on the XC (Full Windshield) max is 115. Mine is coming with the 90 and I was crying like a baby as to why I couldn’t get the 115 seeing they were identical hulls and the only difference is the windshield, same exact everything else.

You don’t get a congrats yet, pics first

Grew up in a rebel, they look awesome now. Love to see how it works out for ya

Here ya go nhamm, running sea trials.

Oh my, black on black on black on black! What a great looking rig. Hope she performs well for you, congrats

I would guess a Spitfire X7 15″ pitch. I have a tiller 2016 Lund 1775 pro guide with a 90 4S, that came with a Spitfire 17″ alum, and I replaced it with a 17″ Spitfire X7. picked up 3 mph, and apx 150 rpm, and a better hole shot also. Look at the weights of the two boats, they are probably close. If you are going to run with two or more people, or want to troll with the main engine, I would go with the 15″ X7. You should be I’m guessing, about 5800 rpm, with a fantastic takeoff.

Enjoy your rig! Happy for you.

Ed, I’ve tested and tested now that I have some break-in time on it. The motor came thru with a 12.75×19 4 blade aluminum Spitfire prop.I did all the testing with a full gear load, 2 people and a full tank of fuel. With the 19″ stocker it would run just a tweek under 5000 (4900) full trim at 40 mph. I wanted a SS prop as the main and use this one for an extra. I was interested in the Spitfire X7 4 blade SS and with the use of the Merc prop calculator numerous times kept coming up with the 13×17 so I purchased it. Tested again with the same load and this time got a tweek over 5000 and still 40.something mph. All speed was indicated on GPS. So after spending for another prop I really gained nothing other then bling hanging off the motor. The hole shot still remains awesome and to move down another pitch is only going to make my motor run faster without any real gain. Here are some comparison pic’s RPM’s/Speed. Like said, full load and small under a foot chop.

At 5000 rpm’s you are over propped. You need to move down to a 15″ X7, and probably raise the engine a hole. The spitfire X7 props allow you to run the engine one to two holes higher than the aluminum version. Moving the engine up a hole, will gain you apx 100 rpm’s. When I went from a spitfire aluminum 17″, to a spitfire stainless X7 17″, I also raised the engine one hole. RPM’s went from 5350 aluminum, to 5500 X7 stainless, with a much better boat lift trimmed out, and a better hold in turns, due to the increased cupping in the X7. Are you trimming out all the way? Your rpm’s should have went up more with the 17″ prop. My boat is apx the same weight as yours, and I am seeing almost 500 more rpm’s. Also your dealer should not have put on a 19″ prop with that combination. You should have had the dealer change out the aluminum prop for the correct one first, before buying a stainless one, as your rpm’s were so far off that it was just a crapshoot as to what stainless one to get. You need to get your rpm’s up to get in the power band of that engine, and if it means buying another prop, sad to say, that’s what you have to do. There is a strong market for selling your Spitfire X7 17″prop. Also best deal on new Spitfire X7’s is Jaco’s.

The dealer doesn’t prop the motor it comes straight from Lund that way. I had mentioned the install of the motor to the dealer and they said it was mounted at the height recommended by Lund. As far as re-propping now, I don’t think there’s anything to gain in speed and all I’ll do is speed the motor using more fuel and efficiency while slowing the speed in the cruising area’s. I run the motor at 4000 – 4200 most of the time and like said, the hole shot is fantastic. I think I’ll call the dealer and throw it off on them to see what they say.

Never herd of a dealer that wouldn’t exchange props, within the same style, to put you in the proper rpm range on a new boat purchase. That is their responsibility, as they sold you the boat, and Lund has no idea in how you ordered your boat rigged. I would be calling Lund to ask why they shipped it with a 19″ prop, that cant even hit 5000 rpm. That is unacceptable. As to raising the engine, yes, that is on you. I’m still somewhat confused as to why you are only seeing 5000 rpm with that X7, as I have the same prop, on the same size boat, that is about 100 lb’s heavier than yours, and I am seeing 5500 rpm’s. My engine came mounted in the 2nd hole down, and I raised it to the third hole down.

Ed,
Talked to the dealer and all they will do is test and re-test at no charge but.. if they find the prop that works it will cost me at a reduced rate for the prop. I don’t understand how your doing better with the same prop? You have a 90 mounted on a what? My engine is about optimal for height because I can almost blow it out on a turn so I know it’s real close. I might just step into a semi-cleaver 4 blade Power Tech prop. Keep the 4 blade for lift and plane but move another inch lower for rpm’s. I noticed on this years build sheets the prop is not even an option or spelled out as it was for the early 18’s.

Be careful when adding a different prop make to the mix. Odds are the pitches will not equate the same. You really need to try before you buy, if switching to Power Tech. Best bet would be to stick with the Spitfire X7, ad try to find someone that has a 15″ to try, they are fantastic props. Not sure where you bought your X7 from, but you will probably save over $100 if you shopped at your dealer, by calling where I suggested. They are under $400 with free shipping. I am using the 17″ Spitfire X7 on a 2016 Lund 1775 Pro Guide, with trolling motor and three batteries. Boat came with a 90 hp 4s, mounted in the 2nd hole down, and a 17″ spitfire aluminum, running 5350 rpm. Replaced it with a Spitfire X7 17″, raised engine one hole, to the third hole down, 5500 rpm and three more mph, with better over all handling. Check the weights out on the Lund site. I think my boat is about 100 lbs heavier than yours. Not sure why your performance is so bad with the same prop. 500 rpm is a lot. It’s too bad your dealer is the way he is, I would be really concerned with his other service. I guess I have been real fortunate over the years to have some really great dealers and service. Best of luck, and make sure you try that Power Tech before you buy, as odds are, the pitches will not match the Spitfire.

Talked to the Dealer (Owner) yesterday and told him of my talk to their service guy and what he said the end result would be. He mentioned that Lund just sends it thru like that. I mentioned to him it sounded like it was a Dealer/Lund problem and NOT a Dealer/Customer problem. I mentioned to him my optimum operating RPM’s as per Mercury is 5800 rpm’s and I would not be happy doing that at 38 mph. He agreed that there was more he had to get into on it and would call me back.
Believe me… I’ve been thru the pitch ringer and your not talking to a cherry for sure. All props are not created equal. The Power Tech is a quality prop and have had great success with them in the past on other engines. Thanks for the advise.

I just looked at the comparison’s of the 2 boats, yours and mine. Your boat is 200 lbs heavier and 8 inches wider. With the same prop and motor I should be much better in my numbers.

Ya, I guess mine is about 200 lbs heavier, and I think only 3″ wider. Some of the performance difference could be that I sit back further, but it would be interesting to see what mine would do if it could loose 200 lbs, that’s a lot. Merc factory test report showed mine getting 43 mph with the aluminum prop. Best mine could do was 39 mph as it came, but I don’t think it was tested with a trolling motor, and two extra batteries. I do push 42+ with the X7. Good to hear your dealer might be finally helping you out. You shouldn’t have to push them to do that. Bought a walleye boat from Skeeter boat center this spring, and I cant say enough good things about them. They are just fantastic to deal with, as their only goal is to make you happy. Something just does not sound right with that prop only hitting 5000 rpm. Do you live at a higher elevation?

Ed.. I’ve been running under 1000 ft ASL for the most part so that’s not it. I do have 2 – 27 battery’s, trolling motor, lots of tackle, all safety gear and, anchor in the front. All in total I might think there’s 200 lbs maybe up there. Full tank of fuel.. 150 lbs, 1 battery..40 lbs, and 2 people with rods, 450.. so.. I’m hauling 850 extra lbs total.
