| Is there a common history between hulls from Tuffy,YarCraft, and Warrior? I thought I had read somewhere that some designs were the same? if this is true what hulls were the same? When and who made changes and what were the improvements? I think Steve would probably have the most knowledge of this being involved with Tuffy since the beginning of time. Tongue in cheek. Steve's not quite that old.
What's the difference between the 1890 Hi-Perf. V and the 1760 deep-V? |

| Steve is way older than Tuffy boats! Think Adam and Eve time frame! LOL
Not sure if they ever shared the same hulls, but I don't think so.
Difference in the 1890 vs 1760? Almost 2 feet longer, 1 foot wider at the Beam, and an extra 50 HP and 5-10 MPH faster. |

Location: Rhinelander, Wisconsin | The Tuffy 1700 was a shared hull with Yar Craft, Skeeter, Warrior, and Kingfisher (Texas). No one did much with that hull, it was a Cruisers Inc runabout at conception and a great design. Everything from 17.5' up was each company designing or buying designs. |

I went from a 1760 to an 1890 this spring. Had fished in an 1890 but never really looked at the hull until I got my new to me boat. From a detail perspective the 2 are completely different. The 1890 has a stepped transom, the sides aren't as vertical, and at rest there is a whole lot more hull in the water but on plane I bet it has less. Hard to describe without just looking at each hull. A 1760gt could fit inside the 1890gt. They both seem to sit the same distance above the water when you are standing on the deck. The 1890 is a good bit more stable at rest. With the exact same HPs I bet the 1890 would be able to keep up with the smaller 1760. I'm guessing that has to do with the pad in the back. Both in the tiller version lean to port bad at mid range when the passenger is a good bit heavier than the driver. Both go dead flat at full throttle. I bet the console guys hardly notice since they cruise at what my tillers maxed out at.

Use your trim switch more than you might think necessary when running low speeds with a heavy port load. Trimming up will help, all the way down will add prop torque. |

| Steve,
Will try trimming a bit more but even with a hydrofoil it wants to porpoise when trimmed up a lot. One thing I have noticed the 1890 is WAY more trim sensitive than the 1760. |

Location: Rhinelander, Wisconsin | Don't overtrim, just feather it, it's common error to over-trim a high performance hull. What prop are you running? |

| Yes, both tillers. I had a 1760gt before now I have an 1890gt. The old one had a 75yammie and the new one has a 90 merc. |

Is a hydrofoil really needed to keep a 1890 tiller from porpoising?
Will a different hole mount or prop stop it? |

| Boat came with a foil and I think it runs nice with it. I would be surprised if it performed well with a 17 pitch 4 blade prop without the foil. Not sure what raising the motor would gain as the rpm are right where they need to be at full throttle and a normal load. I'm sure it could spin a 15 with no foul but the faster cruising speed of a 17 is nice. |

| What is your top speed?
Steve,what prop typically does best on the 1890 tiller? |

| Other night fully loaded with 2 people and 71ish water temps had 37 on the GPS. Saw 38 heavily loaded in cold water this spring. I think lightly loaded with just me I will see 40 on the gps in this boat. It's a tiller under 20' so not a speed demon by any means. |

Location: Rhinelander, Wisconsin | the 1890 Tiller loves a Rev 4 or similar 4 blade. |

Location: Hayward, WI | I have Nick's old 1760GT (great rig). One of the props included is a 16 pitch Silverado Stainless (3 blade) prop. With just me and a light load the boat will do over 36 MPH, and cruises at 26-28 nicely. I can't trim up a lot without the prop starting to throw water slightly and over-rev. The 75 Yamaha is mounted one hole up from the lowest position. Would dropping it to the lowest hole possibly give me more trim range?
I often find myself with the motor trimmed all the way down in anything over a moderate chop to keep the bow from bouncing. In smooth water, I only lose about 1 MPH with the motor trimmed all the way down compared to it trimmed out as far as I can. I could pretty much always run this boat with it trimmed all the way in and not really notice anything out of the ordinary. Other boats I've owned would plow water trimmed all the way in.
There's no way to know without trying, but I am wondering if dropping the motor down the last hole might be worth a try. The cavitation plate is currently above the waterline even when trimmed all the way in.
Also have a 4 blade 15P stainless that I think gives me more trim range but I haven't run it in a while so I don't remember the details. Better hole shot but significantly slower crusing speed than the 3 blade.
The dimensions on paper of the 1760 show it to only be 2" wider and about a foot longer than my old Alumacraft Navigator 165, but in reality the interior space is much, much bigger. Looking at Nick's 1890 GT - there is some serious interior space in that boat. The glass hull beats aluminum in every way so far, in my opinion.

Location: Rhinelander, Wisconsin | You can drop it down if the cavitation plate is out of the water with no issues. It may slow the boat down a bit. |

| Ifr I don't get one of the new pro guides,the 1890 is going to get serious consideration. especially if its hitting the upper 30's |

Location: Hayward, WI | The Pro Guides look like a very nice boat, but I have heard they can pound in good size waves. Shallow deadrise or something I seem to remember reading about a while ago? Having owned aluminum and now fiberglass, I can't think of anything at the moment that would get me interested in another aluminum boat.
Nothing at all wrong with aluminum and it will do most anything it's asked, but so far the glass does it all better in my opinion. If you're looking for interior space that 1890 tiller has a lot of it! Even the 1760 is very roomy. |
