Nautic star 2110 problems

[ricky2110]

I have owned this boat for one year and for the most part its been a very good ride. Throughout the year though i have been battling porpoising problems with this rig. I have tried lowering the motor and i have tried a different prop but the results are the same. The slighest bit of chop and the bow wants to start coming out the water. Today in the lake there was barely any wave activity at all and I had to keep the trim way down and also let off throttle just to maintain control. i have trim tabs on the boat, but honestly do not think they should be needed in chop thats under 1ft. I feel like i should be able to run that wot and trim up some as well. I cant be the only one out there with this problem. Any help is appreciated.

Im in a 2011 2110 with a 150 opti on it . I dont have that issue with mine at all. I also dont have trim tabs . The trim tabs should be correcting that for you .

[ricky2110]

the tabs do correct it for the most part but i dont want to use them because they slow the boat down and mpg goes down as well. even on a glass straight away the boat will want to start porpoising at a certain point. the more weigh in the boat the worst it is. I seen some posts on the net with some ppl having this problem just like I have, but dont see a solution.

Get under the boat and make sure it isn't concave under it. Friend had a glass boat years ago and it was doing the same thing.

do you have a jackplate???

where are your batteries stored??

[fishinpox]

I drove a dudes 21' nautic star for him 1 trip just to show him around hopedale n I think I remember the same thing I couldn't trim up to get the rpms up with out that " bounce"

[ricky2110]

no jackplate, batteries under console except cranking.

[PUREBAY2200]

hmmmm.... my boat had a similar issue. the back end sat low, i had a 225 4 stroke on it, and a jackplate. it was alot of weight on the back end.

i ended up putting 4 25# bags of sand in the anchor locher up front and storing all my hear on the front deck space.

had trolling motor batteries in the concole and a cranking in the rear deck storage.



never really got it solved, but the weight up fromt did help.

my issue was running thru a chop and bow lifting up. and ehwn taking off it wanted to squat then all of a sudden jump on plane.

take it to ur dealer, let them run it and see what the issues looks like....

trim tabs help u said???
might just have to give uo some speed for a better ride.

good luck

[ricky2110]

trim tabs do work, but only to a certain extent. I dont care to use them unless I am in 2+ft chop. it planes off fine, very little bow lift actually, but once up to speed she wants to start lifting and if the trim isnt down it gets out of hand. i tried to use my friends 21p prop today which is the same prop thats on the yamaha bulletin, but results were the same. my friend and my father in law have blazer 2020s and they ride much better. one powered with a 200 and the other with a 150. i know im not comparing apples to apples, but it rides like there's a "problem". i didnt think it was to much of a big deal until today when i tried the other prop it really ticked me off because i was expecting something different. Im lucky if i use my boat 10 times a year but when i do i use it for a couple days at the camp and we ride from montegut to timbalier island so i want to get this resolved before we start hitting the beach in the summer.

Maybe try n lower your motor 1 set of holes on the transom

[PUREBAY2200]

check the yamaha performance info, see what mounting holes they use.....

[jchief]

Where is your cav plate in relation to the bottom of the hull?

[PUREBAY2200]

i say we all grab some beer and go investigate!!

[ricky2110]

im on the second hole from the top, going to have to check out cav plate later today. Anyone willing to investigate will recieve beer upon arrival.

I have an 07 2110 with 175 Suzuki and mine has never had that prob.

[CajunChristian]

The more rake a propeller has, the more bow lift it creates. The more cup a propeller has, the more bow lift it creates. Most CC rigs have a hook built into the rear corners of the hull. If not, that's an easy fix with a little splash zone compound. Just because a company can build a boat does not mean they can build it right, just sayin. Most boatbuilders I know happen to know ZERO about performance.

been working like a hebrew slave all day so didnt get to go look around the boat today, but was thinking if my motor is to low, would that make things worse or better? i lowered it down one hole in january and this week was the first time i ran it since. they been killing me with ot at the job.

We have a 18 ft aluminum boat with a 90 e-tec and the boat wanted to do that a lot we put one of those fins on the motor and that seemed to help out our problem when the trim is set right.

Get rid of that powetech and get a yamaha saltwater series prop and make sure your engine height is correct like already stated. Powertech makes good props I just don't care for them on a bay boat. The saltwater series is made for a bay/offshore boat and perform way better.

Whale tale fins are nothing more than a bandaid for a prop issue. If your boat benefits from one you have the wrong blade design for your hull. Only exception to that is tunnel hulls that run oversized marsh tails to keep the water on the prop.
