Calling for all fish Nautique numbers

No i dont want your phone numbers. (i already found them)
Can we start a thread showing peoples fuel burn, speed, WOT, running gear, prop size etc, etc?
I know everyone with a Fish has google searched for this before and it always winds up with hours or reading and researching before coming up with no definitive answer.

I'm splashing this weekend and i 'm going to gather some real numbers before i order my new wheel. I'm looking to keep this thread simple, maybe post a picture of what your running since Every fish out there seems to be outfitted differently,
I've seen T tops, radar arches, mini fly bridges, seating in the bow, open bow, tanks in the floor, tank in the stern. batteries aft, batteries forward. etc etc.
running with full tank, empty, ice box full? live well full? trim tabs?

ANY information your willing to share will help me, and every other Fish owner in the future to make decisions on what wheel to run, or anything else.

I'll start and fill in the blanks once i launch.
-1979 Fish
-351W approx 260 hp? no idea really
-not sure the gear ratio
-13x9 Oj
-T Top
-open deck
-Fuel tank aft 75 gals
-Batteries aft lazaret
-cruise speed......@......RPM (on plane)
-WOT speed .......@ .....RPM
-Approx fuel burn........... GPH @..........RPM

anyways, i think this is some good info to share between these boats because of all the differences between them and now that everyone isn't quite running the factory propellers its good to share.

Tony:

Check that fuel tank capacity on your chart. Just pulled my Fish's tank to replace it and mine has an 85 gallon capacity. Perhaps they changed tank designs between the 79 and 86 models? We will not be launching until maybe Labor day, bottom painted this past weekend, will be installing new power, drive, fuel tank, electronics, and re-working all the thru hull connections before we splash it. Will post up then with performance numbers.

only choice you have is 13x11.50 or 13 x10.50 in the acme , 10.50 maybe if your running super heavy , 11.50 works perfect for normal loads , moved my batteries forward , helped get the front down , can sit and drive now , before had to stand to see , don't have tabs 2700 RPM = 24 MPH , that's with a prop guard , stock 351 , gets on plane better and much smoother

I agree with that one. especially those of us with the fuel tanks out back.

Wanted to update, My first splash this season went well, bilge pump got some use because the sea strainer was leaking a little, (was expected with the cracked cover)

There was a pretty good sea on saturday so i didnt really mess with the trim tabs at all, they stayed cocked and locked in the upright position during my tests.

in MPH not KNTs
with the OJ 13x9
3800 @ 25MPH
WOT I hit 4300 @ 29.5

4 people aboard, 3/4 tank and two coolers.


edit*
john looks like your running 1000 rpm less with that acme than i am with mine, what are you getting @ WOT for rpm and speeds?

I run my 61 year old, 51 year old and 38 year old engines WOT without any worries! Is there something that worries you about the engine?

moved batteries from over stuffing box to front of big hatch in the floor , 2 optima 31 yellow tops , 65 lbs each , blems from interstate for $80 each , 1/0 wire , 3 runs , so switch stays in the back , 30 foot total at $ 1.75 a foot , go with the 524 and leave some people home

That is one sweet looking FN.

Thanks! Tony I believe you are under propped. I sprayed it with 545 primer and awlgrip really happy with the result. Did the whole inside and floor and added nonskid. It takes a pretty good beating and blood cleans up easy. The t-top flips forward with console.

northstar those numbers are phenomenal. I have a feeling i'm a little underpowered as well as underpropped after hearing a few of these others.

I have a 351 ford Pleasurecraft inboard in my Fish Nautique. Although it runs great it is only 260 hp and the fish is a heavy boat. I would like to go up in hp to the 300-320 range. What are my options for bigger blocks that will still bolt up to that transmission. Laird


i did a repower in a fish nautique with a 6.0 mpi 375 hp. same gear same shaft
they had a hose that went to the fuel return and a plug converter
the boat was an absolute rocket holeshot was amazing
top speed depending on fuel and passengers was upper 40's
cruise @ 3400 rpms was high 30's

then we did one on a ski nautique with a 5.7 325 hp mpi
same thing was very fast
and ease of insallation was great . i think it was done in 2 days with all the extra work we did
i would never go back to using a ford in any nautique

yanmar lh 230 hp , last made in 2006 https://www.youtube.com/watch?v=QhfaNsrD9FA

So i put the 524 on last week and did some testing,It did just about everything i asked of it. Except it brought my WOT RPMs down to 3800. My WOT speed was just shy of 30 knts, cruise around 20knts at 3200 RPM, comes up on plane nicely. ( i dont know the MPH i was doing because i didn't have my electronics on board during initial testing.

So yesterday i fished a small local tournament and had 4 people on board about 100# in the cooler fishing gear and a full tank of fuel. I was cruising around at 3000 RPM range on plane at about 25 MPH most of the day I'm very happy with that for a cruise.

Its almost like its a different boat. maybe it was the way it was loaded up or maybe the characteristics of the new prop but I didnt take a single wave over the bow and it was blowing 15 out of the east. which usually i'm getting a little wet in those conditions.
I'm pleased with the 524 Prop. now i just need a bigger rudder and i'll be happy.
thanks for the recommendations guys.

I thought so too but i think i may have the wrong cam or something else is happening because i'm just not seeing it. with that prop.
with the 13x9 OJ i was getting about 4200 max @ WOT. so it makes sense it would be down 400 or so from what i had.
oh and heres a picture
