hello everyone
i have a new 2006 nitro 750 nx dc with the standard optimax 90
have had it 2 weeks and been to shop 2 times for what i call a very serous lean to the port side when comming out of th hole it will settle down a bit but still is very unnerving. tracker has replaced the original prop 19 with a 20 and still not any better it is in the shop today and been on the river 2 times today with the service man. and the gen. man. they called this evening to tell me the are putting a hydrofoil and a 19 4 blade trophy prop on to see if that helps they are stumped,as well as i am
this is my first nitro is this going to be an ongoing problem or are the experts not telling me something or is there something else wrong other than the prop
thanks for your help
PS great site

My NX750 leans some, mostly when starting out and stopping. Once on plane it levels out when I trim it up. It is annoying, but I have not experienced anything severe. With a partner it leans left (port) more since I have an extra trolling motor battery on that side as well, otherwise its a list to the starboard since all the weight is over there when I am alone. Otherwise its fairly level most of the time I am running. I have the stock 19" alum. prop with the optimax 90.
I put a Stingray Hydrofoil on it the other day... WOW was the result, I think you'll be impressed with it. If you want to know all it did for my rig you can read it at http://deepsouthbass.com/bobsmith/articles/stingray.html (my personal site)Without the 'foil I would get a lot of water onto the rear deck when stopping, I've eliminated that as well. It also porpoised real bad in turns, the foil eliminated about all of that too.
I would think a 20 pitch prop would be a little too much for that motor/boat combination. how did it run with that prop (other than the lean)? I can just hit the rev limit with the 19 on mine (single console, 2006 model).
This is my first Nitro as well - had it since the end of Jan. Have not decided if I'd like another. There are some things I don't like, like the cloth "handles" on the battery compartment lid ripping already, a cooler that isn't anything more than uninsulated storage where 2 bags of ice are gone by 9am, and a couple other little things like that.
The OptiMax I love (just not on a small boat, but I've resolved that issue with the Stingray Hydrofoil); I think it burns water since 26 gallons lasts me about 3 trips and a tournament, sometimes more :)
Wow, sorry I got longwinded.... I think the hydrofoil will solve much of the problems you are encountering; JMO.

BassinBob when you get a chance,, could you look at your boat and tell us what holes your motor are mounted in. I.e is it high, ow in the middle? Or :-* post a photo of your motor set up? Do you have a jack plate? ghettofiremn, do you have a jack plate? can you do the same please. Even if the boats are the same, and the motors are the same and the props are the same, something is different. Most times when you get a lean like your talking about its due to prop torque. The motor and prop are trying to spin the boat rather then the motor spinning the prop. If the motor is set to low you can get a big lean while trying to come out of the hole, or while trimming down to come off plane smooth.
when you get a chance shoot us a photo so we can compair them. My guess is that the shop/sealer would rather put a foil on it rather then readjust the motor if you don't have a jack plate. Takes trial and error, and if your a ways from the water, and don't have a jack plate it could take some time to dial it in right.
Sure thing about some pix.
I inquired about a jack plate, but with that HUGE motor on the back I decided it wouldn't be a good idea to add another fifty pounds or so to the back end :)

The motor is mounted low, in the top hole.

I added the Stingray Hydrofoil Stabilizer last week with awesome results, and it has the stock 19" alum. prop.
Hope it helps some....

The new ones are not that heavy, and the set back and lift with help every boat. Sure glad you had some luck with the foil, & thank you for the photos. Now once ghettofiremn get time we can look at you two boats side by side.
By the way if your tapping your rev limiter from time to time, you might could go to a stainless without loss of power. Stainless won't flex like an alum. prop and you might pick up a bit more top end.
I've been considering the SS prop, but right now I don't know about investing much more money into the 750 since I am in negotiation with manufacturer on a boat sponsorship - among others - with plans on returning to B.A.S.S, BFL and possible FLW next season. If all works out well I will no longer be running the Nitro. Not that its a bad boat by any stretch of the imagination, but I would be moving to a bigger, faster and better rig. Might try keeping the Nitro as well though, I do like the boat now that the performance issues are mostly taken care of :)
