    List of Issues You've Had with your Nitro/Tracker

    2005 Nitro NX-750. Problems with the boat, broke a steering cable at WOT so I replaced it with a Bay Star hydraulic set up rated for 150 HP max. I have owned it for 10 years and am quite pleased. The motor that came on it was a 2006 115 OptiMax and it was grossly under powered. I repowered to a...

    2005 Nitro NX750 Repower

    Yes it is 135 max. The 135 is also a 6 cylinder and the exact same weight (431 lbs) as the 150 pro XS i put on. I tested the setup with a Laser 2 25P and it was a little too much pitch. I am testing a 24P trophy 4 blade this weekend to see if I can get my RPM's closer to 58k. I will say this, I...

    Nitro 640LX struggling to get on plane. Help!!!

    I had a similar problem with my NX750 opti 115. I had an older 22P laser II with the small square vent holes and it was a dog trying to get up on plane. I recently picked up a newer 22P laser II with the PVS large round vent holes. The difference was night and day, it allowed the prop to spool...

    2005 Nitro NX750 Repower

    I have a 2005 Nitro NX750 with a 6" manual jack plate, and a 2006 Merc 115 Opti that is losing cylinder 3. I got a good deal on a 2014 Merc 150 Pro XS and should have it installed the first/second week of Jan 2024. I've been trying research a prop setup but there's not a lot out there. The Nitro...

    Battery Durability

    It's a portable Jump Starter. One of our club members had his cranking battery die early in the AM during a tournament, and he was able to start his boat 6 times using the Halo 58830. He gave us a show and tell at our next meeting and several of us bought one and it's come in handy multiple...

    Battery Durability

    I carry a halo bolt 58830 with me at all times. I never have to worry about a dead cranking battery again :)

    Hello From Warner Robins Ga!

    Andy here from the Warner Robins area. I have had a 2005 NX750 with a 115 Merc Opti for about 4 years now and still love it. Its been a solid boat so far but every once and a while a minor repair is needed. Lately I have been noticing that my steering has been getting stiffer. I drove my buddies...

    2001 Nx 750 Set Up

    Lightweight, that 19 pitch sounds like it might not be enough. Do you have access to a friends 21P or 22P that you could try? I have a 2005 NX750 with a 115 Optimax, 5.5" manual CMC jack plate set at 4" below pad, prop is a laser 2 22P with cup added, and i'm hitting 50 mph GPS in the summer (53...
