Prop and jack plate help

[Squall Line]

Hello all,

Background:
I have recently acquired a G3 1756 tunnel hull with a 4 stroke Yamaha 60. The boat has the flotation pods as well as the T&H manual jack plate. I am planning on purchasing a 4 blade prop and a hydraulic jack plate to help run better in the skinny stuff. I had a few questions though before I pull out the CC and get some parts inbound.

Prop: I am wanting a 4 blade, but something that doesn't sacrifice too much on the top end. I am thinking a cleaver type would fit the bill, but I would like to hear the opinion of folks more experienced than my self. Aside from the style, I also need some guidance on pitch selection. The engine is currently turning 48-5200 RPM at WOT... 5-6K is specified in the manual. The current prop is the stock 3 blade aluminum unit in a 15 pitch. I would think I would have to back off to a 13 or 12 when stepping up to a SS 4 blade... any advice on this would be appreciated. Brand suggestions would be much appreciated as well.

As far as the jack plate is concerned, I would like to hear some input on the brand selection. Right now I am leaning towards the T&H hydro unit as it is all in one, and has a nice gauge package. The other option with a nice display is the bobs machine, but I am not too fond of the remote pump. The T&H manual unit that is in place now has a 5" set back; am I correct in assuming I might be able to run the motor higher vertically with a larger set back plate due to the 'cleaner' water, or would that be a marginal return?

p.s. I have a tach and water pressure gauge

TinCan is our resident expert. I'm sure he'll read your post but you might shoot him a PM just to be sure.

I have heard that the "Bobs" unit is the most trouble free one you can buy.

Go with the Bob's plate.

You gain more height with more setback, to a point. It's different on every boat. The only way to know is to devise a way to vary the setback on your boat to find the optimum setup. (I can show you a way to do this if you want to spend $100 to find out)

I don't know why you would want a cleaver type prop. They're designed for flat out running, and you'll lose your hole shot.

I'm running a Turbo Flats IV. Not the best prop out there, but not bad for the money. Powertech makes a better prop, and will probably work with you to get the prop somewhat matched to the boat.
