Nose cone installer recommendation?

[Robbie Racer]

Can anyone recommend a good nose cone installer? I want to try a IMCO nose cone on a new Bravo lower to use as my spare lower drive unit. I can't get my boat on plane with my Bravo lower with the WPM nose cone with 32 and higher pitch props but have no problem with my IMCO lower unit.
Thanks,
RR

Hey Robbie, Call Titus @ Custom Marine & Welding 1-256-272-0500. I just had my sportmasters modified & coned, EXCELLENT work. If He will do Your lower, Ask him about modifying the cav plate like he does the sportmaster. (Helps to get on plane).

Mike at Prime Marine did mine nice work!!! 909-484-8338

GREAT information. Thanks a bunch guys. I will start making some phone calls.

Whats it do RR,just blow out or what?Too much drag?

With the Bravo/WPM nose cone combination it starts to get on plane just fine with 32 and 34 pitch props, but just as the nose starts to drop down, it blows out the prop and won't grab again until the boat almost comes to a stop. I can't figure out why it does it with that combination and not the IMCO SC lower because I think they are both the stardard height lower drives. I'm going to double check that again though to make sure.

the imco has got to have a lower X dimension if ussing the same prop?when bow drops down on initial takeoff is when cavitation is most likely to occure with high Xdimensions.anything is possible,but never heard of cone causing this prob :confused:i would have the leading edges of your prop rolled slightly,but not to much as topend will start to suffer. keith i can reccomend a kick ass prop guy here in sac,especially with bravo1 four blades.Gary peeler at tru-pitch propeller 916-397-1126.he has been in boat business for 30+ years.good luck

If the IMCO lower does have a lower X-Dimension, that would make sense. I actually didn't measure it myself and just took the guys word that it was a "standard" length lower unit when I bought the Bravo/WPM deal. I did send my 34 lab prop down to Throttle Up in Houston last year because it was cavitating a little when getting on plane even with the IMCO lower. They rolled the ears like you are talking about and it did help a lot when getting it on plane with the IMCO lower but is still a problem with the Bravo/WPM set up. I will just switch back to the IMCO lower and the problem should be solved. IF the Bravo lower is a shorty, that would cause the cavitation and I will try and sell it to someone that can use it.
Thanks for the contact information for Gary. I will give him a try the next time that I need some prop work done.

Glen swapped out my Bravo/WPM lower (broke prop shaft and trashed lower gears) to my IMCO lower today. He measured the X-dimension on both and says they are within 1/8" of each other so don't know why one blows out with high pitch props and the other one does not. I didn't have that problem until I put the nose cone on the Bravo lower. With the stock Bravo lower it wasn't a problem. I will get the IMCO nose cone installed on my other stock Bravo lower housing and swap all the B-Max guts from the Bravo/WPM lower to this one and see how it performs. Weird stuff. :rolleyes:

Man sorry to hear all this bs happened to you, I was going to put the one on my drive but maybe I will let teague do it so I dont have to go throught all that bs. Please keep us posted on what happens.

Keith,are the low water pickup inlets below the point of cone on both cases?same amount and shape?you tested both cases ussing same prop?you going to red bluff,if so stop by

[Robbie Racer]

Okay, I called Titus at Custom Marine, Mike at Prime Marine and Bob at Bob's Machine about installing the Imco nose cone on my Bravo lower. Bob said he only installs his own nose cones and won't do the Imco. Titus says he hasn't installed a Imco nose cone but doesn't think it will be a problem. (I forgot to ask for an estimate). Mike at Prime says he should also be able to install the Imco nose cone and gave me an estimated price of $650 to $750 (including the $86 nose cone and other incidental misc. parts). That seems a little pricey to me but I don't remember what I paid several years ago to have the WPM nose cone installed. What do you guys think?
Thanks again, RR
ps: Kevin, the low water pick up in the Imco lower is only used to cool the drive. I use through hull pickups for the motor cooling and innercooler cooling. The Bravo/WPM lower has the low water pickup closed off and has a small external water pickup installed in the cav plate to cool the drive. All tests were run using the same 32 lab and 34 lab props between the two different lower units.
I won't be making it to the Red Bluff race this year. Good luck and kick some butt in the 10 second bracket class. :hammer2:

[Robbie Racer]

Thanks Kevin. I will give Gary a call to see if he is interested.
How did you do at Red Bluff this past weekend? I saw your other post about it getting blown out on Saturday but someone said the weather was good on Sunday.

Kevin, sorry to hear about the red light at the races. That has to be frustrating for you not to be able to run your motor to warm it up real good like the car motor guys to do in the pits. I still don't understand why you are not able to warm it up in the pits though. Does your prop have to be turning to force cooling water through the motor? Or, do you need higher pressure than you can get from a bucket and pump to force it through the motor?
I called Gary at Tru-Pitch this morning. As you suspected, he is much too busy to get to it until this winter. I think I will just replace the broken prop shaft in my existing Bravo/WPM lower spare and keep it as my spare and just not run high pitch props when I have that lower unit on it. I am reluctant to spend $750 to put a Imco nose cone on my other Bravo lower and then find out it didn't work any better than the Bravo/WPM combination. :cry:

Keiththese motors have all aluminum bores with a thin coating (.010)of nicom/nicasel which works real good at disapating heat off piston and will never cold sieze even if you hammer it from being dead cold.so getting heat in motor is not a real issue as two strokes get there lub from gas/oil mix.these motors also dont have thermostats and only run about 20 degrees warmer then lake water.the digital EFI is kinda crude as there is no O2 sensor or throttle position sensor,just a vacumm assisted map sensor and air temp sensor.you actually take a chance of fouling plugs if you rev motor with no load on it as map sensor sees low vacumm when you crack throttle plates and tells ecu to go full rich.at next race i will try hotter spark plug to see if that helps.you going to chowchiila on fathers day weekend?

[Robbie Racer]

I'm going to try and get out to Chowchilla for a little spectating on Sunday. Hope to see you there (and at Shasta the weekend prior to that). :D
