175 faststrike prop?

[Ron G]

i have 180 bumble bee bass boat with 175 johnson with a jackplate prop is a rengade131/2x25 4 blade runs great with one person still cant get the rpms up runs at 5500 around 60 to 64 mph with fishing buddy and his gear gets 55 mph at 5000-5200 holeshot is terrible,so questionis it fesible to have more cup put in the prop i have now or will it be betterto drop down a size?also a seen a prop on a yammy last night and it looked like the edges were cut off it was a ballistic i think whats the purpose in that?

Re: 175 faststrike prop?

I cant remember -- is your jackplate manual?<br /><br />As for the Ballistic (or Bull-istic) props, the only thing I can see for the design was that when Attwood started making them they wanted something that looked radical and was cheap. They sold a ton of props quick and then sold the division to Michigan wheel. They seem to work OK once you have a specialist re-work them but at that point you could have, money-wise, bought a good prop in the first place.

D it is a manual 10" jackplate .

Re: 175 faststrike prop?

Very good. Have you tried small adjustments up? I know it may not help much with that small diameter but we should try.

Re: 175 faststrike prop?

no i have not raised the motor up it seems like its high now i cant tell you right off hand but it seems the cavation plate is about 4"above the bottom of the boat ill try to get some measurements and let you know.wouldnt raising it make it slower coming out?just curious

Re: 175 faststrike prop?

also D,I was reading about decarboning on the F&a page i've never decarboned this boat and i bet its never been done think its worth doing?i never even herd about doing it until i came to iboats what a wonderful board with great people.thanks

Re: 175 faststrike prop?

Yeah, it cant hurt (as long as you follow the instructions on the can). Thats a good place to start.

Re: 175 faststrike prop?

okay ran boat idials great runs great with just me and my gear can get on planein roughly 15yards coulnt get my rpms over 5400 at around 61 to 63 mph,partner gets in he weighs around 195lb taking off took about 30yards to get on plane everbody beat me out of the hole,ran 56mph at wot 5400rmp this trimed all the way up.i dont want to losse my top end but top is no good if everbody else is already 100yards in front of you by the time i get going?so any ideals will help.

Re: 175 faststrike prop?

So we've slowed down with the exact same prop and jackplate height, right?

Re: 175 faststrike prop?

ive done nothing to the jackplate or prop yet.

 

[Ron G]

Re: 175 faststrike prop?

ive got pictures of the boat and jackplate if can figure out how do put them on here ill try to,would raiseing the motor up help any?

Re: 175 faststrike prop?

OK, I reread everything so at first we were at 5500 and 60-64 mph and now were at 5400 and 61-63mph. OK, thats not bad.<br /><br />Did you put in new plugs after the decarb?

 

[Ron G]

Re: 175 faststrike prop?

d i put new sparks in last month just like you told me,after decarboning i cleaned them up they look like new

 

[Ron G]

Re: 175 faststrike prop?

D finally got these pictures with alot of help from the little lady,hope there alright. <br /><br /><br /> <br /> <br /> <br /> <br /> <br />

Re: 175 faststrike prop?

so does anbody think raising my motor will help or should go down a little in pitch,if i do go down and raise the motor hows my top end and holeshot going to be?

 

[Dhadley]

Re: 175 faststrike prop?

Raising the motor is free and easy. And changing it back is too if youre not happy. Just watch the water pressure. That hull design should respond well. <br /><br />I'd try some new plugs too. The decarb process can be tough on them.

Re: 175 faststrike prop?

ill put new plugs in it,so do you think raising it will help my holeshot?should i raise it about 1/4 inch at a time or more?thanks D

Re: 175 faststrike prop?

Any time you lose drag (less gearcase in the water) and the prop still hooks up, you gain across the board. Holeshot, cruise speed, top speed, top rpm, fuel milage -- everything. Just watch the water pressure.<br /><br />The ideal X dimension is where the prop vents ever so slightly as you take off hard but bites (hooks up) again on its own. Generally speaking -- if you can use all of the trim range you can go higher with that prop.
