Nose Cone Install ?
 

I looked up threads on this and havn't found what i'm looking for yet.My ? is has anyone installed hydromotive cones where it blocks your low water pick up and if it did what was done if anything to the pick up.I have a xz lower with dual water pickup.Will this hurt or help.I was told it will increase water pressure but i'm already running water pressure relief vavles on my 525's.It runs at wot between 30-40lbs of pressure now.Been told will gain 4-7 mph.The boat 70-95+ runs like its on rails now so is it even worth installing?

Re: Nose Cone Install ?
 

Good question,my spare drive has dual pick ups and no nose cone because I haven't been able to find a nosecone intended for dual pick up,Smitty

Re: Nose Cone Install ?
 

Teague has them. I am haveing them installed on my bravos.

Re: Nose Cone Install ?
 

What would it cost to have them put on and repainted tota???

I wonder if its a hole lot would it be better to go ahead and swap out the foots with one that allready has it built in?

I have done both of what you are talking about. I am doing one for Dave now that is a low water pickup. I did 2 for Lotti a few weeks ago. Dave is using the Imco, I used the Hydromotive on mine. I think it is worth the effort above 85. What you will start seeing is small burns on the prop near the hub where the water is pulling away from the prop. It basically is cavatating in the small circumference.

Call me after lunch & I can talk you through it.

It was $250.00 for the nose cones ,epoxy and filler. I will know more next week what it cost me to have installed.
My lowers had to come off anyway. :D

Re: Nose Cone Install ?
 

Strip i talked to Mike the guy that sold the 388 to Don and he said he had to put nose cones on he's 388 and what a world of differance it made over 90 mph.

Re: Nose Cone Install ?
 

when i first did my motor the boat ran 91 with out a nose cone i put on a wpm nose cone and went 96 at a lower rpm so yes they will help you above 85.also it is very importent thet they are stright on the drive if you have never put one on you might get some one to help you that has done they and had them work for them . also they can be stright side to side and up and down good luck

Re: Nose Cone Install ?
 

Who's installing them for you and how much ?

Re: Nose Cone Install ?
 

A few years ago I had a nose cone installed by Bob's Machine. It was for a Bravo and I believe it was $275-295 installed including the parts and repainting the lower. I think they even included a warranty on the paint.

Re: Nose Cone Install ?
 

We saw a big difference at about 85 and above on a high X dimension cat with twins. One drive with a nose cone and our spare drive without. RPMs on drive without nose cone climbed a last faster above 85 than the one with. Put the right drive back on and RPMs were the same.

Re: Nose Cone Install ?
 

Fred the cones came in on tues. thanks.I know a 388 that put them on and did make a big diff. and especially in handling over 90+.Fred if you like and want to install mine for practice i can send my drives to you. :D

Re: Nose Cone Install ?
 

Rich, do you have a tig welder?
if you do start grinding your lowers, i know you like the thought of that :D:
I'll help for a gift cert. :drink:
they are not that bad you can either spot weld them then epoxy or just epoxy.

Re: Nose Cone Install ?
 

No welding to be done on my drives.Good since it looks like it will be raining on sat. then i'll be at the shop at 7 am well better make that 8 am. :drink:

Re: Nose Cone Install ?
 

At the risk of sounding stupid, who is the manufacturer or what is WPM?

Re: Nose Cone Install ?
 

Fred, So Hydro has a nose cose for a Bravo 1 drive that has ONLY the low water pickup? I have hull mounted offshore water pickups so that's not the problem. The low water pickups on the drive lowers are used for the top cooler cap. Richard

Re: Nose Cone Install ?
 

I think WPM is Warlock Performance Marine.

Re: Nose Cone Install ?
 

do you have a picture of one? Will they work if all you have is a low water pick up?

Re: Nose Cone Install ?
 

Rich,

Send the nose cones to rivas. I saw the ones he has done and they look great. If you call him he would probably do them on a weekend, maybe when you pick up your boat.

Re: Nose Cone Install ?
 

Fred, How much are the kits?

Re: Nose Cone Install ?
 

$99.95

Re: Nose Cone Install ?
 

Will and I did them saturday in the shop well Will did them and i helped Lori in the tanning bed i put in the shop.Sure glad i never built any walls around the bed. :D :D

Re: Nose Cone Install ?
 

got a picture fred? Mine xr has only the low water pick up. Does yours work for that?

Re: Nose Cone Install ?
 

dude,
you sure had the right bait for her! :D: now your electric bill is going to go up and your gonna have to start stocking "Grey Gooose vodka cause she will want to come over all the time now :drink:

Re: Nose Cone Install ?
 

gs mine has a low water pick up too.all i did was drill a hole in the cone where mine had been covered up from the cone.i'll take pic in the morning and post it.

Will i'm stocking the shop bar with grey goose aslong as Lori wears her new outfit she showed us sat. :D :D

Re: Nose Cone Install ?
 

yea , she shops as i work,:D:
i like the outfit too :evilb: :evilb:

Re: Nose Cone Install ?
 

Here is what they look like before and after.

Re: Nose Cone Install ?
 

Rich, that looks good. are you going to paint it black or leave it? Was it hard to sand the epoxy?

Re: Nose Cone Install ?
 

Black and not to bad sanding.

Re: Nose Cone Install ?
 

This is what you need Rich, Don't play with "Mini Me" nose cones

Re: Nose Cone Install ?
 

Finished mine today.Need to put 1 more coat of black on them in the morning and done.

Re: Nose Cone Install ?
 

i still like the grey :D:

Re: Nose Cone Install ?
 

Is that the Hydromotive nose cone? Wow, it looks small. :eek:

Re: Nose Cone Install ?
 

A few people down here have painted them aluminum and they dont look bad. I think Imco does that as well.

Re: Nose Cone Install ?
 

Yes it is.Does size really matter ? :D

Re: Nose Cone Install ?
 

Rich, I don't see in your pics where you drilled the holes for the low water pick up.

Re: Nose Cone Install ?
 

Just took these.

Re: Nose Cone Install ?
 

I always say size doesn't matter as long as it's getting he job done! :D

BTW, I had my boat at the house today and realized that's not really small. Guess I figured it would cover the lower more.

Question, how does it affect the speedo pickup on th leading edge of Bravo drives? It looks like it covers it up. And I like me speedo for pointing out to passengers how fast "we're going". :evilb:

Re: Nose Cone Install ?
 

GPS.or drill a hole just for the speedo if you don't have a gps.
