Re: Ran Dom
 

Is that a 1:50 ratio?

Re: Ran Dom
 

yes 1.50

The sportmaster -2 lower was virtually the same results, the only difference was I was using labbed 30's that I borrowed for the test. (I have not tested with labbed 30's yet) I did notice I had no trouble planning with the Bravo Shop lowers & the boat seems rock solid on the top end. (I did not have the cavitation plate bolted up when I tested the sportmaster lowers)

Re: Ran Dom
 

Did you find a market for your used Bravo lowers? You must have had no water pressure issues, like I have read with the Imco's? Did the prop gods think that you would have any more performance with 5 blades? I was told that if I did the upgrade that I should try the 5 blades in case there was slip from going higher.

This is good stuff for those of us thinking about upgrading. Thanks again.

Re: Ran Dom
 

I did manage to recoup some of the cost by selling my stock cases. No water pressure problems with my set up. (next year I'll try 5 Blades) need to save some $$ for gas :eek:

Re: Ran Dom
 

Any test results with Imco lowers on the same boat?

Re: Ran Dom
 

What kind of water pressure issues are you talking about?
I also have been thinking about going with another set of lowers.

Re: Ran Dom
 

Apparently the front water pickup on the imco case is a bit larger compared to the merc. or B-Shop lower which in turn causes higher water pressure. This increased pressure may cause a problem on a standard open cooling set-up. A pressure relieve valve or sea strainer can be used to relieve this increased pressure.

Re: Ran Dom
 

I agree with Ran Dom, have a couple friends that run the Imco lowers, both had high water pressure issues, both installed strainers and dump some off. My understanding is that Imco has a kit of some sort to create a pressure relief.

Ran Dom --- That is a nice gain you made there, shorties cost some dollars but likely the cheapest speed gain avaliable, once the prop sorting out is maxed. Keep us posted if you get a chance to try some other props. Did all the internals change over ok, and allow for proper set up specs ?

Re: Ran Dom
 

My water pressure went thru the roof when I put the Imco shorties on.

But to heck with these shortie drives. Someone needs to step up to the plate and put in a couple of those new Merc 700's with the new style drives. Peter, you are nominated! With your dealer discount you should be able to get those packages on the cheap - probably around 60k each vs 83K retail. Then you would have that 100+ mph turn key boat :)

Re: Ran Dom
 

Thanks for the vote of confidence. If I buy the first one are you throwing in for number two ? I would for sure cut you in on the dealer net price for the second one. Actually I can bum a seat with MV 35 , He's run 109.9 so far , or get in with my other buddy, Anthony , he's running 100+ as well , best part of Anthony's boat is it's an anniversary , so it's just like being in my own boat. The single step 35 hull is as at home at 100+ as it is at 80+ , makes you think you should take advantage of the hulls ability to run those numbers........................ There I go with that thinking thing again , If I think too much , I'm going to end up just like you !!!!!!!
