87 skeeter 175 / 175 mariner setup

[pmgoffjr]

Altitude is going to make a difference for sure. Under 2,000 not much but get above 3 and it’ll be very noticeable. I had to drop three inches of pitch when we went up to 5,000 ft.

The answer is there won’t be a magic prop that runs at all altitudes.

We had no gps back then cant say how fast it was but it hurt a lot of feelings . If your running in higher altitudes your going to have to go smaller in pitch . The comment about needing to prop the boat so it lifts is right on . That was a great haul in its day . The 1988 starfires hauls were know for extreme gel cracking . The next generation haul skeeter made I was not impressed with being a gear head . Rode rough and the boats were heavier . One thing you need to do is pop the bumper rail out ( middle section only) . Take out every screw one at a time inject a adhesive silicone in every hole and install the screws back in place . If you don’t vibration will back them out and top cap will be running lose on top of the haul . I had 2 starfire ser skeeters and both were bad about that . A 23 tempest might be a good choice to start with . They lift Good and 23 might be just right if your higher up in Altitude.

At 5,000 feet you’re gonna lose 4-600 rpms and have a pig holeshot.

Everyone who fishes different altitudes have a high and a low prop. One prop won’t get the job done.

So what would you suggest for my high alttitude prop? And already be close to the 3,000 ft elevation as you speak about losing rpms, would the 25 pitch still give me the bow lift and speed for that hull?

I hate asking the same thing over and over bit i want to be positive before i buy a few props.

And thanks for all your help. Its appreciated

Let's compare a sea level setup to an altitude setup.
Here that boat with that motor rigged on that jack plate will turn a 25M yamaha wheel (ready to fish, I never ever quote light and dry results) 5,700 rpms at 65-67 mph.
At three thousand feet, you're going to lose about 150 rpms and a couple mph. You could leave it alone, or you could have that prop adjusted to get the rpms back.
At 5,000 feet you'll want to run a 22ish prop. 1 inch prop pitch will average about 200 rpms. 1,000 feet of altitude will cost you about 100 rpms.

What you're probably having a little trouble grasping which is fine, your prop can be worked (by a skilled hand) to deliver exactly what you need. Sometimes you hit the exact prop out of the box, sometimes not.

I understand you're in Idaho, which is not exactly the center of any bass boat pool of knowledge, but you have access to those that do. Mark on the prop page here, or Steve at fork are both guys that can tweak what you've got into what you need, don't send it to some knucklehead that doesn't have their clue ticket punched.

Proper boat setup takes time and effort, there is no perfect setup because no two hulls/motors/props/loads are exactly identical. You start with what should be close, and see what it does, and adjust from there. Shortcuts? Not if you want to find potential.

New update.

Borrowed an 24" tempest today from my local boat shop
Set at 3"
65mph gps at 5300rpms
Still no bow lift and no rooster tail

Nah run a 23 and get it worked if needed

[JamesfromID]

I thought you told me to run a 25 yamaha?

He did. The 23 will work best for you. If need be, you can get it worked to fine tune it for your set up.

Ok. I started off with a 23p quicksilver and could do over 54mph. He told me the 25 yamaha would work the best. So i try a 24 tempest and i picked up 11 mph but 5300 rpms. So now i should go to a 23p again and have it work? Im glad i didnt buy the 25p yamaha he recommended.

[pmgoffjr]

I did say 25, which is the right prop at sea level. You’re not at sea level.

Lol. Hmmmmm.....

Ever since asking setup information on my boat day one, in my first posts, ive stated what altitude im running at. You still told me to run a 25. Few posts later, you sent me link of a prop i should get, again still knowing what altitude im running. Now im confused.

Your advice now is to run a worked 23P yamaha even though an 24 had better performnce so far than the 23 i currently own? No disrespect pat, but it seems these last few posts have been a waste of information based on providing you best accurate information (speeds, rpms, and most of all altitude) and you giving me recommedations for sea level. I never go to sea level.

[pmgoffjr]

I think you need to just take it down the road.

[JamesfromID]

Lol. Is that with or without my high altitude?

Not sure why youre pissed. You werent the one about to waste $400 on a prop that YOU suggested and then all of sudden "not the prop i need" a week later. In fact telling me to stay with a 23P in which it fell on its face with that pitch and slow as hell.

You either make suggestions based on not reading the whole post or you jus like people to waste money. From another post ive read, im goin with the first one. You made a suggestion and then caught yourself for not actually reading it. So pat, with your "skills", im not impressed.

It sounds like the 23 is slipping badly. A balance and blue print should make it run a LOT better, probably similar speed and at the right rpm as the 24.

Or......if you've already bought the 24 and it ran so much better than the 23, maybe get the 24 worked. Mark can get your rpm's up and add some lift to it and it could gain more speed.
