Low Water Nose Cone - questins?
Anybody running a low water nose cone?
Did you get any improvement in performance? Was it just from being able to raise the motor higher or did the lower profile of the additional material help make any noticable difference at the same level? -- Bob La Londe www.YumaBassMan.com All about fishing in Yuma, Arizona Promote Your Fishing Website FOR FREE

Low Water Nose Cone - questins?
Bob,
I run a shallow water lower unit on my boat, not just the nose cone. But, here is what I know about the add-on units. That is what you're talking about, right? You will get a small improvement in performance from the improved hydro-dynamic shape, if you run the motor at the same level. Will it be noticeable "seat of the pants?" Probably not. Where you do pick up performance is running the motor higher, creating less drag due to less lower unit in the water. One thing that I can see for your application is due to the shallow running that you do, less motor in the water will be a good thing. Sometimes, an inch of motor height will be the difference between sticking/striking the lower unit or running free. You should be able to punch up on plane in shallower water too. The units from Bob's Machine Shop have good reputations. Just make certain that you have a water pressure gauge and you watch it all the time. Running a motor too high is a certain recipe for disaster. -- Steve OutdoorFrontiers http://www.outdoorfrontiers.com G & S Guide Service and Custom Rods http://www.herefishyfishy.com "Bob La Londe" wrote in message ...

Low Water Nose Cone - questins?
A low water nose cone has water pickups on the bottom front of the nose cone
to force water into the cooling system. This allows you to lift the motor further out of the water to reduce drag without overheating your engine from inadequate cooling. Very common for speed boats. I am interested in it from both a performance perspective, but also to run my engine further out to clear sandbars and rocks in the river. -- Bob La Londe www.YumaBassMan.com All about fishing in Yuma, Arizona Promote Your Fishing Website FOR FREE "PB" wrote in message m...

Low Water Nose Cone - questins?
Bob, not specific to your question..but ... I recently changed out the
engine on my 14 Carolina Skiff. The Mercury installers in Illinois did NOT understand the full effect of the set-back/tilt/trim CMC PT35 unit that I had previously installed on the boat. The new Merc's anti-cavitation plate was placed exactly at the bottom of the hull of the CS. My performance was markedly poorer than I had experienced with the predecessor engine of the same hp. My local guys in Houston, (North Shore Marine) who know shallow water needs, re-set the engine up about two inches to conform to the setback. Performance improved markedly, Up on plane quickly; obviously shallower running and floating allowed; better top end speed, etc. It seems like anything that we can do ( within reason) to get the prop a little higher (assuming one has a set-back plate), while maintaining its driving force IN the water, improved my performance a lot.

Bob - don't confuse the shallow-ability of this unit with that of a jet
drive. Your prop still must be submerged for it to work, meaning it's not for navigating ultra-shallow waters. Especially rocky ones... Warren "Bob La Londe" wrote in message ...

Low Water Nose Cone - questins?
I used to run a nose cone and low water pickups on one of my boats. In my
experience, unless you also go super-radical with the prop (small diameter, over the hub exhaust, severe front hook, massive cup and minimal rake, paper thin blade chopper which usually equates to a diminished hole shot and questionable rough water performance) the advantages of a narow, slippery lower unit are minimal. But with the right prop (and of course a power jack plate) the combination can make for unbelievable top end performance. But there's still a control trade-off. With only the bottom of the prop and precious little skeg in the water, the boat really walks sideways as it runs. RichZ© www.richz.com/fishing

Yeah, you're absolutely right, but you'd be amazed at the difference an extra couple of inches can do for your "room to roam." -- Steve OutdoorFrontiers http://www.outdoorfrontiers.com G & S Guide Service and Custom Rods http://www.herefishyfishy.com
