Left Hand Prop on a 27 Fever Questions
 

Well...I've got a "new to me" '94 27 Fever this year. It had a 23P Mirage Plus on it when I got it. I read on OSO that a LH prop should work better on my boat so I bought a LH 22P Hydro Quad. When I put it on my Bravo I, I thought I'd check it out for performance before switching the cable on the shifter. I expected the shift positions to be backwards, but they weren't. Of course this didn't show me much because I think the prop is still turning right which means I'm catching water on the back side of the prop...right? :grinser010:
Right now I'm the fastest backing boat on Texoma! :lolhit:
Question 1: How do I get my Bravo I to do a left rotation so I can use this prop?
Question 2: Do I have to disassemble the shifter to change the cable positions?
I know I can do this...I just need a little knowledge base from OSO. Thanks for any and all help...it's defiitely appreciated. Jim

The shifter should allow the cable to be reattached in the opposite side. Word of warning on rotating LH. I have seen boats snap shafts in Bravos from doing this very thing. The shafts take a set in one direction and now you are loading/twisting the shaft the other way. Can lead to failure.

are you having any other issues that would make you want a lefty prop , i use a 24 p bravo 1 prop rt hand and it works great i think . it is not the most top speed prop but it does everything well handle, hole shot ,stay on plane at low speeds so far so good .all i can say is that rt hand props work well for me .

Thanks Brad...so just moving the cable connection to the opposite side will cause the shaft to rotate left? Also...are there any shortcuts or tricks to moving the cable to the opposite side?
Thanks...jim

Hey Money455...the main reason for going lefty is to counteract the starboard list I'm getting with my mirage plus. I may have second thoughts after reading Brads reply about the busted shafts. Thanks for the input.
jim:coolcowboy:

no problem really interested to hear how this works out for you , a few people have told me of that issue "listing" and i have never encountered it sad to say . just wanted to let you know that if things do not work left there have got to be other props to try to fix the right hand list !

oh by the way any pics of the boat i would like to see ,also what engine/displ. do you have and do you have a stepped hull , i ask cause i do not and i wonder what was the the year of the first stepped 27 . thanks

i thank the first year step in 27,s were 95.i have had left hand and right hand props on my fountain and the left hand are faster and ride w/no list.factory prop for a 94 27ft fever was a mach 1 stren-driver,lh24four blades.i have on mine now a 26lh bravo1.w/502 mag

94 step
 

i have a 94 with the first step believe it as a special order until mid 94 than became standard..

Ditto on BCFountain...I've never heard about the special order 94's before. Anyway, I put a pic of my 27 as my avatar. I don't know how to download pics yet. I've got a naturally aspirated, punched-out genVI 502. It runs pretty good and sounds better. I just bought a Stainless Marine exhaust to install this fall...don't want to miss any h2o this summer. It's already going too fast. later

well what the he*# should i be running a left hand prop ? why is a lefty faster ? if i dont have a list is it worth going to a lefty ? i have always thought my boat was kinda slow for what i think it should be but i am pretty green when it comes to how things work with powerboats/fountains.

It's kinda general knowledge through feedback that the NON-step single engine fountains did better with left hand props. Lots of them came that way from Fountain.

Still yet, every boat is different in that no two are exactly the same so you may benefit by experimenting.

I run LH

thunderstruck does yours have a step? mine IS A 94 and it has a step. its left hand rot. also but its a IMCO had a 30p brovo labed but took to long to get on plane running a 26 brovo now and much easier to play with

lh props
 

the way reggie explaned it to me was that a left hand prop counters the engine rotation and allows the bow of the boat to be lifed and carried easyerwhich translates to better performance.

My '94 fever is non-step hull...this is my 1st summer with her so I'm doing what upgrades can be done on the fly...like stereo, pwr steering pump, ingnition...stuff the previous owner let go...

okay bcfountain thank you a ton for what you just said , that makes sense to me and how that would help the boat . i am going to try a lefty now just to see what happens you da man . i have asked that question alot about if i should be running a lefty or not and i have always got b.s. answers .

I tried a LH on my boat this weekend.

Could not believe the difference and was not expecting it to be that significant.

It was terrible. Could not wait to get out of that boat. Nasty, God-awlful ride.

Entire characteristic set changed for the worse.

At least now I know...

That's interesting.
One thing I noticed when we went for a ride on your beautiful boat is that you had to lower the port tab a bit while accelerating and at mid range, to keep her level.
With mine, which has a l/h prop (and always had, since the performance report), I don't need that.
Therefore, I assumed that the l/h was more appropriate for the F27 hull.
Now you make me wonder if it's worth trying a r/h prop also on mine!
Or do you think it can be so different from one hull to another?
There aren't many years between our boats, mine is a 07 model and yours a 05 as I recall?

Details? What exactly, was so significant?

At this point I don't wanna say cause I may be wrong. If you're getting good numbers that match the report than I'd leave it alone I suppose unless you want to tinker.

Boat has always had a "slight" list to port. Nothing huge just wanted to see if I could make it "perfect". The last 4 feet of my bottom have been blue printed to perfection. So.....

Instead of a list to port, it listed hard to starboard more than counter acting my initial complaint.

It was bow heavy and a much, much rougher ride and seemed to porpoise at every ripple.

It did not track the same either. Felt like I was always making a left hand turn etc.

I could not have been more surprised by simply changing the prop rotation. Could not take on any other boat wakes without getting wet and just felt very abnormal in every way.

I've spent so much time running this boat that I pretty much notice every little detail.

i just wasn't expecting such a big difference that's all... Suked.

Put it like this: I DON'T EVER go home with 3/4 tank of gas. It just doesn't happen. But it did this time. I wanted out.

What kind of prop was it?

Stock Bravo I 30 LH. Exact opposite of what I normally use..

I realize the story doesn't make sense but the difference between the two props was stark.
