Re: 175 faststrike prop?

A couple of things come to mind but I'm not sure if either one is what's going on.<br /><br />If the tach is off and you're really at 6200 it could be on the limiter but your numbers look good so I don't think that's it.<br /><br />The linkage could be off and the last little movement doesn't do anything. But I don't think it would be that far off.<br /><br />It's not unusual that the last little bit doesn't do anything but not that much. I'll have to think about that one.....

Re: 175 faststrike prop?

I don't know how to explain it right now. BUT, it's got something to do with the power and load (somebody help me here).<br /><br /> Anyway, it probably has less to do with your engine and more to do with (enginesin general).<br /> My underpowered car hauler comes to mind. You can load it down and drive it up an incline at 60mph with the gas pedal half way down, "feathered" on the verge of 59mph.<br /> Put it on the floor and you can hear it, but, you can't feel it doing anything else...won't go any faster either. <br /> Best I can tell, all you are hearing is more gasoline going thru it...lol.

Re: 175 faststrike prop?

Ron G,<br /> There is a basscat on ebay with a 175 Merc. It has a few mods and the description tells about them. Using the mods as a selling point, so, I doubt he left anything out.<br /> Looks like a 175 merc with an aftermarket intake, some exhuast work, solid motor mounts.<br /> Claims it's seen 85mph on gps. <br /> 75mph at will, in almost any conditions.<br />Goes on to say any idiot (us) can drive it 55-60 all day long, but, takes some learning to go faster.<br /> Says he will spend a day with the new owner gving them a crash course in this.<br /> SO, I'd say he's on the level.<br /><br />Maybe I'm just not smart enough to drive my boat that fast? Seems 60-65mph is where I start having my problems and this is the speed other boat owners (several others) say you need to be skilled to go faster?

Re: 175 faststrike prop?

Brownie i think you may have the power to punch on thruogh and find that fine line of driving at high speeds,fill the boat up and find some open water and start running it until you the hang of the chinewalking but be carefull,for some reason in my mind that hydrolic steering is hampering your ability to cut the wheel with the walk.<br /> On my boat bymyself i can run it wot and walk it now with the chine i just cant get over 65mph yet.but i want to make sure i got this thing set up to its max capabilitys as it is rught now.<br /> know this boats will run,my buddie has the same boat i do,but with a mariner built to 200+ it will run high 60 and low 70 easy yhe has to drive it,but his hole shot sucks and he int going to mess with it any,he may pass me but i'll be gone and at 60 before he drops over :Dwe will get all thuis figured out,i wish i could get mine out but i blew the transmission in my truck last week coming from tourny,so i'll be workink on that for awhile.

Re: 175 faststrike prop?

I would believe the guy with the Basscat isn't far off. A few years ago I went to the factory and drove a couple. If the guy has close to 225 hp he'll be in that ballpark. <br /><br />The ones I drove had Pro Max's on them. Once we got away from power steering they were pretty fast. A bit of a handful with the hydraulic but not impossible to drive. I don't know how fast it actually went, the speedo only went to 85 and we had the needle past that. It was a Gafferig so I'm sure it was fairly accurate. And it was over 100 degrees the days I was there.<br /><br />They're very well built boats, excellent rigging, really nice folks and a fun boat.

Re: 175 faststrike prop?

I'm seeing the part about the hydraulic steering now that effects this. <br />When I got this hydraulic, it was THE BOMB! (I heard some kids say that here while back...lol).<br /> Anyway, it was the greatest thing I'd ever bought for my boat.<br /> Instructions said to use an even spoke steering wheel. My idea of "why" was that it probably had some "bleed by/off" or "drift" in the steering wheel. YES, steering wheel is never in the same place twice when boat is loaded.<br /> Still, didn't bother me at all.<br /><br />NOW it does. I think it bypasses slightly due to the pressure of torque steer, or, just the pressure of turning makes it bypass. OR, I'm just imagining it? I get that "soggy" feeling when trying to adjust the steering to compensate for shine walk.<br /> Is that correct or am I just imagining it?<br /><br />Dhadley, Kenny...ONE MORE THING. I'm 1.5" below the pad with the propshaft now. <br /> WHY WHY WHY will be Yamaha M series 25p prop take off with a GOOD holeshot. And get me into chinewalk at 63mph.<br /> -vs- the 25p Tempest. It blows out when the boat breaks over on plane, grabs, lets go, grabs again...finally on plane....then it will run on up to 65mph before the boat starts chinewalking.<br /><br />I just want the top end characteristics of the tempest with my Yamaha 25p to get me there...lol.<br /><br />Could there be something wrong with the Tempest?

Re: 175 faststrike prop?

I won't mention the name of the shop, but a couple of years ago, Bass and Walleye boats had this gentleman work his magic on a Merc Trophy...<br />Out of the box, the prop blades were 2" different in pitch from low blade to high.....<br />Could there be a problem?????....maybe, but I doubt it. The Tempest is a fast prop, but it may not have the right lift-qualities for what YOU need.<br />We're a long ways past this most likely, but are there any issues with the boat bottom at all??????<br />If you have a transducer transom mount that is down too far, it can create problems at high speeds....something even that simple can do it.<br />My next question for you would be: Have you ever considered a Turbo Lightning?????

Re: 175 faststrike prop?

That soggy or mushy feeling is exactly what we try to avoid on performance hulls. It could come from line expansion or the type of fluid. Dont use anything except the aircraft grade fluid they recommend.<br /><br />Ahhhh, the Lightning. I wondered how long it'd take to bring that up....

Re: 175 faststrike prop?

I was wondering too :D I know the turbo 2 is awsome,i did get out yesterday with a passenger,my paretner was over 300lbs full tank of gas and tackle,i was surprised my hole shot was awsome still and still ran 55mph at 5500rpm,still had plenty of petal left just like before???????My partner couldnt believe my holeshot with him in there compared to the last time he rode in it.

Re: 175 faststrike prop?

Still running the Yamaha M 25p. I gained speed today with a passenger. (saw 65mph). 63 was a good speed and when he went to get the truck, 63 was a good speed by myself.<br /> (lost 5mph with passenger using the Tempest 25p).<br /> Anyway, that "un-named" prop shop will be working on my prop, once I find the one I like best. I was told to send the prop I'm going to run on the boat. Not to just send "any prop". However, he said he did like Tempest's...and also Yamaha props. (more like once I decided on a prop, it'd be nice if it was one of those two choices).<br /> I've checked this hull every possible way I can think of and it all looks fine. I think my transducer is in a good place, but, I'm moving it inside the hull as soon as I get a chance...just to be sure.<br /><br /> I'll be playing with a 25p High Five tomorrow...It's just too cool looking for me not to give it try. LOL.

Re: 175 faststrike prop?

It's always been on my mind. I'd sure like to try one if I could find one. Just not sure where to look (I have done a few searches on websites, although, looks like they may have been feeble attempts). Seems everybody knows what a Lightning prop is but me...

Re: 175 faststrike prop?

Please advise. Where can I get a lightning prop or a "TXP"?<br /><br />Yamaha "M" 25p (good hole shot, smooth transition from standstill to 63mph, chinewalk bad at anything more, controllable at 63mph).<br /><br />Tempest 25p (decent hole shot, blows out as boat breaks over on plane, boat falls back, grabs again...finally up on plane..Runs smooth and controllable at 64mph (65-67mph possible sometimes).<br /><br />Think a TXP or Lightning might offer something better than each? (I just can't run that Tempest any more due to the way it acts taking off).

Re: 175 faststrike prop?

The Lightning has a tad more bow lift than the TXP although they're really close. The TXP's are designed to be on Allisons or Bullets etc.<br /><br />Let me see what I have laying around.

Re: 175 faststrike prop?

I've not weighed this boat, but, it sure strains my single axle trailer. <br /> Usually I carry two spares with me and an extra hub.<br /> I can't think of a problem that this trailer hasn't had (there's nothing quite like breaking a leaf spring while running down the highway).<br /> The tires always look low (everybody notices this also).<br /> It will be tandem as soon as I get a chance. I sure hate to take it very far away from home right now.<br /><br /> Ron, I think it's okay to post this link here. It's something I found for prop calculations.<br /><br /> http://continuouswave.com/cgi-bin/propcalc.pl
