Bobs nose cone good?

[wizard8575]

Ok I am really tempted to buy a bobs nose cone so I can let my motor go sky high with out loosing pressure. I have a pressure gauge but whats fun about having a jackplate without being able to use it right? Let me know if there are any other options or suggestions.

Wizard, if you want to jack the motor up your only other option would be to get a Sportmaster or CLE (for Black motors) If your lower is cherry its a good Bang 4 the Buck. And yes I have 2 lowers with the Bob's conversion.

How fast are you running now? Before you go throwing money away on a nose cone, you should know that you have other options. I have run my 225efi bolted to a 10" jack plate in the highest position with the plate jacked all the way up and never lost water pressure. This was on a 2100 Pulsare and a 2000 Pulsare. If you need to go higher, they make a set of scoops to go over the water intake on your lower. The thing about a nose cone is that if you are running slower than 75mph, it will probably slow you down. My 20' Pulsare was running 76 on gps without and after it was installed, 75. There is a fine line as to when they start to gain speed and this is different on every boat. Do some research before you spend money. boatman

i run my motor on a 12 inch jackplate 2.5 inches from the bottom of the "v" and no low water pick-up(stock lower) the only time i start to loose pressure is when i turn really hard one way or the other......i wouldn't spend the money-my 2cents-ross-

Hey wiz, you will lose 2 MPH easy with the same setup. I did in my predictor when i installed a cone. BUT, I had the power to swing a bigger prop.

IMHO on your boat, I would just run it as is and be happy. unless you plan on doing 70+ and running a big chopper on it, I would leave it alone. its a pretty nasty job and you will NOT want to take it off once its on.

I am not all that worried about losing a few mph. My main concern is the fact that I like to push stuff to the limit to see what it can do. Knowing that I am afraid I will jack up the motor all the way just to see what kind of speed I can get but what if I do it for too long. I like kary he is a cool guy but I don't want to keep spending the money redoing my motor once is enough to scare me. I mainly want it just for the secuirty of knowing I wont burn it up. And with how high those intake holes are compared to the hull on my boat looks like they will be high and dry. I have a welder to tig it I can do body work to smooth it out if I only spend the money it costs to buy it how can I loose.

My 2 cents for what it is worth ... Just for the peace of mind install a nose cone if you have access to a tig it is and easy job take the time to make sure it is straight with the lower unit. Measure from the tip of the cone to the back edge of the hub .. same for the top measure from the leading edge to center of the back keep measuring all through the welding.
weld in 4 or 5 places down both sides then weld it out when you order your nose cone order a torque tab to weld to your skeg this will help with steering if you have to much pull in your steering at high speed you can change this by changing the leading edge of the nose cone so do not paint it till after you have ran it and done all adjustments... Drill and tap two holes to feed water to your pump and you are done.. if you need any more info PM me I will be glad to help if I can

The purpose of installing a nose cone is to run the prop higher without losing water pressure so that you can GAIN SPEED! If you are going to lose speed, and you will if you are currently running less than 75, it would be a total waste of money. This would be like paying someone $300 to unhook 2 spark plugs on your Corvette. Myself and many others on this board have spent thousands of dollars making these boats go faster and sometimes slower. Do some research on this site and others (s&f) and you will change your mind. The nose cone increases the length of your lower unit which increases drag. It will take at least 75mph to overcome the extra drag and see any benefit. Spend your money on a better prop. boatman

What about noseconing a big drive like a Bravo? At what point would it be advantageous to nosecone one of those?

I agree. The stock case is better at carrying the bow at speeds below 70 MPH. The lower unit intake "Scoops" would be a better choice for your application. I run them on my stock 3.0 liter 225 gearcase/Pulsare 2100/Trophy Plus 26 and they work great. My boat runs consistantly 72-75 MPH.

Ditto...all you need is the scoops!

I guess I missed something. I thought the idea of a jackplate was to tune your boat to run faster. Why install a jackplate and then do something to lose what you have gained? By the way, I sell Bob's nose cone kits and probably cheaper than anyone else and I would love to make a sale, but I hate taking someone's money for nothing. Good luck. boatman

What is the name of your business or how does one get in touch with you?? I have a friend that is going to be buying 2 or 3 that I will have to install. We always like to save a few bucks!!

Send me a pm and we will hook up. I am just now getting my business started back up after a long hard move. boatman

Gary, on my Sportfire which was not a 75 mph boat I gained speed when installing the Bob's lower. The whole idea is to be able to raise the motor which the LWP lets you do. With less lower in the water there is less resistance. An added benifit was that it improved the handleing of the boat. I agree that if you were to just add the nose-cone and do nothing else ofcourse it would slow you down (more surface more drag) but I installed mine so I would be able to raise the engine and run a surfacing prop. The GPS don't lie, I gained mph and thats a fact.

I think every scenario will experience different results.

Shameless, many of the regulars to the Site have purchased items from Gary (Boatman). I definitely recommend him.

GOOD LUCK GETTING BACK ON YOUR FEET GARY!

Thanks Hotdaddy! There are exceptions to every thing. But the imformation that I am speaking of comes from my own trials and what I have seen from others on this site. My first experience with a nose cone was on a 2100 Pulsare with a 200efi(merc) that was slightly modified. All of the mods were done at the same time so I can't tell you that the nose cone helped or hurt. My GUESS is that it helped. The boat ran 79mph on gps and was verified on radar. My next experience was on a 2000 Pulsare with a 225efi(merc). The boat was running 76 on gps with no issues! The boat handled like a dream. There is a video on youtube of the boat at speed. The set up seemed to be perfect! I sent the lower to Bob's and had them install the cone and when I ran the boat again, 75 was it and I had to drop the engine 3/8" to get that. $300 wasted! I sold that boat and kept the motor for my Enforcer. After trying several props, the best speed was 59 on gps. After hitting a log and trashing that lower, I replaced it with a stock gear case. Now the boat runs 62 on gps. No, the gps doesn't lie, that is where I get my imformation from along with others. The bottom line is, if anyone wants to spend the money to try anything, it's your money and you can do anything you want with it. If you want to buy a nose cone kit, I will sell you one as cheap as I can. The only thing I ask just like anything else that I sell to my C-mate brothers on this site, is report your results to us honestly either good or bad so that others may benefit from our experience's. After all, that is what it is all about, helping each other. Thanks for listening to my BS! boatman

adding a jackplate alone will net you higher MPH and better handling.

In this case, I dont think he has the power to run a large prop so there is no reason to jack it to the sky. THUS, no need for the cone.
