    New 2007 115's are ready to go. Test run tonight. This boat had twin 90's last year which were strong out of the hole, but lacking on top end. The 115's being V4s should be able to spin the props up to 6000 rpms and give our footers the speed they want. This boat will outpull a single 225 by about 4 people off the dock.

    Nope, boat is a 97. We stripped all the decals off last fall as they were getting pretty ratty from rubbing against the dock. Sponsor decals and team decals will have to go on soon.

    Those baby motors are so cute! They don't look like much more than one of the older 10 horse motors now.

    I've always been curious about how well a small twin like that would perform. Our team has a "spare" 20' hull that we bought a few years ago, painted, and never used yet. I keep wanting to make either a big single or a baby twin out of it before the weather gets to it and destroys it. But alas, our team is not good at raising money, so fun projects like that get put by the wayside.

    Dealers are generally happy to work with you on motors like 115's. This is why we have done this as opposed to another big single. This boat will hold speed better than a single also. It is a little slower on top end, but has more grunt with two props in the water.
    One other thing is that it allows us to break in new twin rig drivers and not let them loose with a pair of V6's.
    We may very well switch our single to a pair of 115's also. There are always people looking for 115's to buy.

    Yes, for some reason, there are not a lot of people out there wanting to purchase an "appropriate" sized motor (200+ hp). May have something to do with coast guard regulations, or just lack of experience. I dunno.

    So, that's why our twin is staying with 150's again this year (first new motors in about 6 years). Much better chance of turning them over than a couple of 200's.

    The Backwater Gamblers put a single 60 on a 20 for a pickup boat. It went 30.

    Well, most boats now that are rated for 150 and up have 25" transoms in the midwest because most of them are deep V's. Therefore you either need to get a 25" transom on your dyne like some teams or just buy your own motors. Some of the motor programs are not nearly as lenient as they used to be before Evinrude's bankruptcy back in 2000.

    We've looked at having one of our twins with a 25" transom, but so far have not had a huge problem selling motors.

    Our program is definitely one of the less lenient ones then, because as of last year, we were required to purchase our motors from the dealer. Prior to that, we were on a "lease" type option. We have never been very good at selling motors, which could explain 6 seasons on our twin 150's.

    River rat, try e-bay I have heard some teams having luck with it. We just purchased our mercs this year and will likely be selling them in August to.
