fish nautique prop questions

Can anyone share there prop info for a 1984
fish nautique. I am so overproped it wont troll well and wont spin proper rpms. thanks
dave. I have the 351 setup.

what's on there now and what RPM's are our seeing would be a better place to start with to choose a different prop. All boats are different and will perform differently depending on how it is used so what someone else has may not be what you need.

For instant If i said i have a 79" ski nautique what is the best prop for that model and year and 99% would say get the ACME 540 or a OJ 13x13 but that just won't work on my boat, now if I wanted to pull stumps and the rope out of the skier's hand, or blow mine up, then ok it might be a good choice but it's not, that's why I use a 470 on mine.

Prop for your boat for your intended use and use what you currently have as a starting point. Or otherwise base it on what YOU ALREADY KNOW not what joe blow knows about his and nothing about yours even thought they are the same boat means nothing. Now if your using it the same and have the same speed and RPM then it could be helpfull and might work then again it could make it worse as well.

ok darrel lick lets try this again I never said use a 540 or 470 on the f**k'n thing. What I said and you totally missed was


"what's on there now and what RPM's are our seeing would be a better place to start with to choose a different prop. All boats are different and will perform differently depending on how it is used so what someone else has may not be what you need"


then I go on and Say " FOR INSTANT......"

Then I finish by saying


"Prop for your boat for your intended use and use what you currently have as a starting point. Or otherwise base it on what YOU ALREADY KNOW not what joe blow knows about his and nothing about yours even thought they are the same boat means nothing."


SO to summerize again it doesn't mean d*ck what some a**hole john33617 has on his boat. LOOK AT WHAT YOUR"S IS DOING AND HOW YOU WANT TO USE IT THEN CHOOSE A PROP ACCORDINGLY.


SO that means DAVE need's to firgure out what is on the boat currently, what is the top speed, what is the max RPM, what is the speed at trolling, what is the RPM at trolling speed. How is the performance to plain or out of the hole?
TOO START WITH THEN WE CAN GIVE HIM A BETTER IDEA WHAT TO CHANGE, DIAMETER, PITCH, CUP, NUMBER OF BLADES. It's not rocket science you just have to know what your starting with otherwise your pissing in the wind like you like to do a lot of there johnboy.

I don't

I'm not married

Me Girl friend is pretty smart and can read and tell the difference between a suggestion and a example.

Long story short Dave need's to see what's on his boat then make adjustments according to that information rather than listen to someone to use this because they did. If I would have listened to Bill Weeks at ACME I would have waisted money on a prop that I would have turned at 6500 rpm.

What I choose to do is verify what I had and then educated myself on what I needed to do to get the rpm I wanted for my application and intended use. Which is exactly the same information I gave Dave the first time, second time and this time. Maybe you should clear your head of all of those diesel fumes or pull your head out of your ass.

I fell sorry for your WIFE, SHE HAS TO LIVE WITH A f**kING DUMB ASS THAT DOESN"T KNOW SQUAT.

that doesn't sound to bad of a direction dave, what's the tune up like? have you had much time to mess with that? diffently too much prop for the current performance of the motor. Does it have points or has it been converted to electronic? By the looks and your comments you want to do a lot of trolling and not much running long distances. Another thing to keep in mind is the load did you have it weighted down with gear, full tanks, live wells filled? are you planning on loading it down more than you did. Basicly it sounds like you where idling and happy with the speed you where trolling at just not getting enough juice for the electronics, plotter, fish finder and so forth.

might want to give it a good tune up and get that conversion kit before you drop down some cash on a new prop, also double check the shaft alignment and make sure it's right. That way you know exactly what your max RPM's will be.

With the difference between the two props it should give you a good indication on what you'll need to fine tune-it to your needs. Not sure if a 4-blade is the way to go usually you lose on the top end with them. ACME actually says there 3 blades come out of the hole better than there 4 blades. With the 3" less pitch I'd saying you should be in the mid to upper 4K range maybe a tade high for the motor depending if it's cupped or not.

Well before you go and spend some cash on the prop double check the tune up make sure the timing is right, throw a vaccum gauge on the holley and set the idle mixture screws for max vaccum and the idle at 600, check the spark plug's gaps and the rotor and cap condition. make sure the throtle cable is adjuster correctly and the throtle plate is opening all of the way.

If the props are dinged up and not blanced then that's not going to give you a very good indication of your actually condition. one was a four that was on earlier and this one was the 3 blade right.

Dave you better jump on that the ACME's are nice props that's what brand I use.

the 13x12 would be equalant to the 14x11 and might even have a slight performance edge out of the hole with the smaller dia and a little on top end with the extra pitch worth a try. I'm sure he would be willing to ship to you and try it out before you buy maybe a small down payment to cover shipping.

Dave, I run a 13x12 3 blade federal on my cuddy which is the same hull as the fish, maybe a bit heavier. It has the OMC chevy 250HP. I am happy with the performance, and it will tach over 4,000K can't remember what the exact RPMs maxed out and I believe I was around 39 MPH. Not sure but I believe it is an original set up in 1978.

Go Dave!
You're right about this site. Muchgood info here. Go Irish, beat Michigan.

Sorry, couldn't help myself.
