Need HELP getting on plane..any ideas??
 

I have a 03 Fountain 27', which had a 496 HO, had very bad luck with the 496. Everyone suggested I upgrade to the 525 , so I purchased a brand new 525 EFI. Just put on the water last week-end with a Hydromotive Q4 26p , with 4 people in the boat, it would take approx 4 city blocks to come on plane, very very embrassing as everyone had to go to the front of the boat for weight. Once the boat went over the hump on plane I had no problem pushing the rev limiter, this boat could have a bigger prop yet but would never get on plane. Any one have any suggestions, besides getting a different boat. I would appreciate anyone's help on this matter....

I would try a bravo 1 prop.
I think they come better out of the :party-smiley-004:hole

26" B1, maybe go to LH rotation because of the engine torque. 02's and later 29's are tricky with Hydros because of the more aggressive setup, so maybe they changed the x dimension on the 27 as well. I know the 27 is a different hull than the 29, but it might react well to a Maximus or P5X wheel as well. And make sure you're K planes are all the way down.

What kind of speeds did you see with the 525? I've thought about making the switch from a 502 mpi. My Y2K 27 is slow to plane also, but not that slow. I've got a RH 23P Merc Rev 4 - we are on and off plane alot. Good luck.

Buy a new Reggie Baja, they never had issues of getting on plane and were the same speed as the 27 with none of the stabiltiy issues.

Dont take offense to this, but how are you getting on plane. I had a 27 with a Hydromotive 4 blade and it wasnt a ski boat, but it didnt take that long to get on plane. Are you putting the drive and tabs all the way down? Ours would just fall over and we lifted the tabs and set the drive. The bravo props will get on plane faster. Does you Hydromotive have a flare ring on the back of it?

I have had a Hydro 26 on my 27 Fountain. Did great getting out of the hole. Hydros will blow out sometimes and you definetly should always lower the tabs to keep the drive happy and help get on plane.

B1 will plane better. 4 blocks what is that like 150 yards. Still not bad with people in the boat.

how much total added weight did you have I had same prob with a 29 fever with a 502 but I had 7 in the boat around 8 900 lbs in just people not including gear and full tank gas.

You have to put the tabs all the way down, drive all the way in then 1/2 throttle till the nose starts to come down, then start lifting the tabs, it will take a little getting used to this way but it is a lot easier on the drive, The 27 and 29 single engines do not plane off fast that is the only complaint with them

Check how far down your drive is going. It should be going down past level quite a bit. I had a 27 Hydro on my 27 last week..No problem ..And I never put a trim tab down all day..Planed off easily without full throttle. Also make sure you new motor is timed right.

I run a 28 Hydro on my 27 and like you, it takes a bit of effort to get it on top. 4 ppl, tank full of gas and gear......mine takes a bit of time, too.

As has been suggested, drop the tabs, ease the throttle and let the boat do its job.

yup....tabs and drive 100% down. 1/2 throttle till nose drops, then start picking up the tabs, and backing off throttle....then start picking up drive to 3-3.5 try a b1 also.....26p these are not fast planning boats.

New motor, drive off, check the location of the plastic insert in the tail of the drive that locates the trim ram thru pin. The insert can be put in two ways, if located to the front, near the transom, of the oval hole it will allow more "in trim". Very easy to mess this up, simple to check and move if need be. Pin needs to be at the rear of the oval hole. to get max in trim on the drive. Can make a huge difference on some boats.

Well you had a real good one!!!:D How's that working out for you so far?

Bow Lift ! I need bow lift ! :D

Brett and I are working on the solution. I turned the 27 at 5100 RPMs though.. :D

Hydros need a step hull..I tink. we are going to try a stock b1 and go from there..next week......:cool-smiley-011:

First of all I want to thank you all for the info, the Hydro 26 does not have the difuser ring and it is not Labed, to tell you the truth I did not put the tabs down all the way because it seemed to slow the boat down and not help pull the bow down or lift the stern, when the RPM get above 2,800 the engine starts to build torque and then will push the boat over the hump, on the way over the hump you must trim out fast or she will blow out bad, it would be nice to have a little slipage on take off and then lock up on top, I would think a 5 blade would reduce slip and make the hole shot worse, once on plane the boat will run 79+ with 3- 180lb. people and 3/4 tank 5400 RPM and a little throttle left, I know the time to plane will never be good but this is vary bad. By the way I have a Baja too with no complaints on hole shot

My 27 would play like hell trying to get on plane with the tabs up. Have to be fully down. Especially with riders, no way around it. As the boat climbs over the hump, start raising the tabs and backing off the throttle to keep it from blowing out. If you wait till on plane before raising the tabs, then she'll bury it's nose. After you get on plane, then you can raise the drive, adjust the tabs and take the throttle up. Sounds involved, but becomes automatic after you get the technique down.

try a box stock b1....26 or 28 pitch. drive and tabs all the way down.

Is this prop LH or RH?

You have to put the Tabs all the way down on a 27 Fever, drive all the way in. The X dim on the Fountain is shallower than your BAJA, thus more top end but hard to plane. I got my 2001 500efi 27 Fever on plane with 12 people on board one weekend, but I would never suggest anyone else doing that!!!!!!!!!!!!!
WILL:evilb:

that would suck....i dont like the feel of the boat with more than 4 or 5 people in it.

Like everyone says the Bravo prop will plane much better. It will give you better fuel milage at cruise speed too.

Getting on plane in the 27 Fountain requires full tabs and full down drive.

Now for the trick.

It will plane better with less throttle. It seems hard to believe but in most cases it will. Think about it this way. When you floor it and the nose goes sky high the stern is digging a huge hole in the water. To get on plane the boat must climb out of this hole. Therefore the smaller you can make the hole the easier it is to get on plane. It takes a while to get the hang of it but it will become second nature. What you have to do to acheive this changes with fuel amd people load but you can feel it.

Everything else everyone said is true. A slight letting off as the boat is starting to come over helps greatly. You will get the feel of how much throttle is required and for how long before you let off and let the boat come onto plane.

The first time I had 5 people in the boat it was embarrassing how long it took to get on plane. After I learned the boat even 6 people was acceptable.

Good luck,

Ron

The Hydro is RH

Thank You Ron I think your right on, the more HP made the hole deeper. what pitch should I try ???

Lee I have a set of 26 bravos at steves shop . Give me call if you need to try left or right.
Jeff

Thank You Jeff, I don't think a 26 will be enough pitch, the bravos are lighter on pitch than the Hydros, I think a 28 would be the right number.

I don't know you might want to try them at least once. B1 4 blade had better performance than my quad 4 blades. You might want to just try.

I think you need a 28. But it may still plane slow.. A 26 should plane right now

Contact B Blades. He is all over the prop talk post. He can rent you a prop to try.:D

words of advice........never turn down an opportunity to try a prop!!!!

for what it's worth........ I have 600hp to the prop and approx 580ft lbs and can't turn my 28 Hydro past 4700. Talked to Brett yesterday and he's sending me a 26 Bravo 1 to try. He feels that's the best all around prop for the 27s. I'll have results end of next week.

I would try the 26 if i was you. I run a 26 b1, 1.5 bravo, 496ho, and can spin the prop to 68.6mph @ 4850ish rpm i think. Your motor will spin to 5400rpm right?........that should get you upper 70's i think with that prop and get on plane how its supposed to. A 28p b1 just sounds like too much.

Hey Jeff-I`ll take the 26p Bravo 1 LH if nobody else wants it!

I have `97 27 with the 500 HP spinning a 24p Bravo 1, and I`m in the 70`s easily, running mid 5000 rpm`s.

Would like to have the 26p just to compare, if it is reasonably priced? :D

James

Sorry to far away for me to have you come and take them off the boat for a day. :D

I misunderstood, I thought you had them up for sale. :(

No problem, just a friend letting a friend try out some props.
